In the evening the temperature is 37.1 in an adult. A fever without signs of a cold is a serious cause for concern.

Heat– a typical symptom in many diseases. It is by focusing on temperature that we often determine whether a person is sick or not. But this is not entirely correct, because temperature is only a manifestation of the disease, and not the disease itself. Therefore, bringing down the temperature does not mean recovery. It is necessary not only to fight high fever, but to determine what disease caused it and treat it. And for this you need to see a doctor.

Signs of a high fever

The following signs (symptoms) may indicate that the temperature is rising:

  • , sudden fatigue, general painful condition;
  • chills (mild chills at slightly elevated temperatures and severe chills at high temperatures);
  • dry skin and lips;
  • , body aches;
  • loss of appetite;
  • sweating (“breaks into a sweat”);

If you are experiencing any of these symptoms, it would be a good idea to take a thermometer.

What is considered a high temperature?

Normal temperature is generally considered to be 36.6°C. But in fact, temperatures within a fairly wide range are normal.

During the day, body temperature fluctuates quite a bit. The lowest temperature is observed in the morning, immediately after waking up; maximum - in the evening, at the end of the day. The difference can be somewhere around 0.5°C. Physical activity, stress, ordinary meals, drinking alcohol, staying in a bathhouse or on the beach can raise the temperature. In women, temperature fluctuations are also associated with ovulation. A few days before ovulation, the temperature decreases, and when ovulation occurs, it increases.

On average, a normal temperature is considered to be between 35° and 37°C. In children under 3 years of age, a temperature of up to 37.5°C is also considered normal. Where you take your temperature matters. You can focus on 36.6°C if you place a thermometer under your arm. If the thermometer is held in the mouth ( oral temperature), then the normal temperature will be 0.5°C higher (36.8-37.3°C). In order to receive normal values when measuring temperature in the rectum ( rectal temperature), you will need to add another half a degree (the norm is 37.3-37.7°C). Based on the measurement of the temperature under the arm, an elevated temperature is a temperature in the range of 37-38°C, a high temperature is above 38°C.

A temperature that rises above 38°C or a temperature of up to 38°C that persists for a long time is cause for concern ( low-grade fever).

When is an increase in temperature dangerous?

High body temperature is an undoubted sign that some pathological process, usually of an inflammatory nature, is developing in the body. The higher the temperature, the faster it rises or the longer it lasts, the more serious the problem that caused it may be. This is why high temperatures are scary.

Meanwhile, in itself, an increase in temperature in most cases is a protective reaction to the penetration of infection. At high temperatures activity pathogens decreases, and the body’s defenses, on the contrary, intensify: metabolism and blood circulation accelerate, antibodies are released faster. But this increases the load on many organs and systems: cardiovascular, respiratory. High temperature depresses the nervous system and leads to dehydration. It is possible that circulatory disorders may occur during internal organs(due to increased viscosity and blood clotting). Therefore, a high temperature that lasts for a long time can pose a danger in itself. Extremely high temperatures (above 41°C) are also dangerous.

Should I lower the temperature or not?

There is no need to rush to lower the temperature. First of all, the patient must be examined by a doctor. You should follow the doctor’s recommendations: if he advises you to lower your temperature, then you should lower it. The doctor makes decisions based on the general picture of the disease and assessment of the patient’s condition, that is, recommendations are always individual.

However, if the patient has a severe fever and the temperature is high (39°C or higher), then he can be given antipyretic drug, strictly following the instructions on the packaging. At the same time, you need to understand that you are fighting a symptom, not a disease.

The correct course of treatment involves identifying the cause of the high temperature and carrying out a set of measures aimed at treating the disease that caused its increase.

Causes of high temperature

Any inflammatory process can cause an increase in temperature. The nature of inflammation can be different - bacterial, viral, fungal. In most cases, the temperature is a concomitant symptom: for example, with otitis media, the ear hurts (“twitches”) and the temperature is elevated...

The temperature is noticeable Special attention when no other symptoms are observed. Temperature against the background of standard signs of ARVI is ordinary, but only one high temperature is frightening.

Diseases that may cause a high fever without other symptoms:

    chronic diseases of the urinary system (chronic,), in women -. Along with low-grade fever, abdominal pain and urination problems may occur;

    chronic myocarditis and endocarditis. In this case, the usual symptom is pain in the heart area;

    autoimmune diseases (rheumatism, systemic lupus erythematosus, etc.).

This is, of course, far from full list diseases that can cause fever

High temperature in a child

The child will not say that he has a high temperature. Even relatively large children, including students in primary school As a rule, they cannot correctly assess their well-being. Therefore, parents need to closely monitor the child’s condition. You can suspect an increase in temperature based on the following signs:

  • the child becomes unexpectedly lethargic or, conversely, restless and capricious;
  • he is tormented by thirst (he asks for a drink all the time);
  • mucous membranes become dry (dry lips, tongue);
  • bright blush or, conversely, unusual pallor;
  • eyes become red or shiny;
  • the child is sweating;
  • pulse and breathing increase. Normal pulse is 100-130 beats per minute during sleep and 140-160 during wakefulness. By two years, the frequency decreases to 100-140 beats per minute. Normal frequency breathing also depends on age, for two month old baby it is 35-48 breaths per minute, for ages from one to three 28-35 breaths.

You can measure body temperature in the armpit or groin cavity with a mercury thermometer (it most accurately shows the temperature), rectally - only with an electronic one. It is possible to measure the temperature rectally only in a small child (up to 4-5 months); older children resist the procedure, as it is unpleasant. To measure the temperature rectally, the tip of the thermometer is lubricated with baby cream, the child’s legs rise, as if washing. The tip of the thermometer is inserted into the rectum to a depth of 2 cm.

We should not forget that in children under one year of age, a normal temperature is considered to be a temperature of up to 37.5°C, and even up to 3 years of age, such a temperature does not always mean that the child is sick. You cannot measure the temperature when the child is very worried, crying, or is tightly wrapped up - the temperature in these cases will be expected to be higher. A hot bath or too high a room temperature can also raise your body temperature.

In young children, the temperature can rise up to 38.3°C for reasons unrelated to illness, such as:

  • overheating (due to excessive wrapping, being under direct sun rays or violations drinking regime), especially under 3 months of age;
  • scream;
  • (if the child pushes, the temperature may rise);
  • (one of the most common reasons).

If it does not seem that the temperature is caused by one of these reasons, it persists and does not subside, or, moreover, increases, it is necessary to urgently consult a doctor. If the temperature is above 38°C, you should consult a doctor in any case.

What to do at elevated temperatures

While the temperature rises, the patient gets chills and feels cold. You want to dress as warmly as possible, wrap yourself in a blanket, and this is natural. But as soon as the temperature rises and the patient becomes hot, care should be taken to avoid excessive overheating: you need to change clothes (or change clothes for a sick child) into light cotton clothes. You can cover yourself with a sheet.

Bed rest is recommended, but if the child is active despite the temperature, he should not be forced into bed, although it is worth keeping him from excessive activity, which can raise the temperature even more.

The air in the room where the patient is located should be fresh and cool. The room must be ventilated, removing the patient to another room for the time of ventilation.

At high temperatures you need to drink more. You can drink little by little, but constantly. Fruit drinks, compotes, diluted juices, tea with lemon, and green tea are excellent.

You should not shower or bathe. You can wipe yourself with water at room temperature or with vinegar (a 9% vinegar solution is diluted with water in a 1:1 ratio). It is not recommended to wipe small children with vinegar. Rubbing with cold water or alcohol can increase the fever.

Antipyretics should be taken as prescribed by a doctor, strictly following the instructions.

In some cases, at high temperatures you should call an ambulance:

  • if against the background of temperature it is observed;
  • if the temperature is accompanied by the appearance of a rash;
  • for febrile convulsions and other severe conditions;
  • if at a temperature above 38.5°C, lethargy and drowsiness are observed;
  • if the temperature continues to rise or does not subside, despite taking antipyretic drugs;
  • at temperatures above 39.5°C.

Thank you

Temperature increase body to low subfebrile levels is a fairly common occurrence. It can be associated with various diseases, or be a variant of the norm, or be an error in measurements.

In any case, if the temperature remains at 37 o C, you must report this qualified specialist. Only he, after necessary examination, can tell whether this is a variant of the norm, or indicates the presence of a disease.

Temperature: what can it be?

It should be borne in mind that body temperature is a variable value. Fluctuations during the day in different directions are acceptable, which is quite normal. None symptoms it is not accompanied. But a person who first discovers a constant temperature of 37 o C can be extremely worried about this.

A person's body temperature may be as follows:
1. Reduced (less than 35.5 o C).
2. Normal (35.5-37 o C).
3. Increased:

  • subfebrile (37.1-38 o C);
  • febrile (above 38 o C).
Often, experts do not even consider thermometry results within 37-37.5 o C to be pathology, calling only data of 37.5-38 o C subfebrile temperature.

What you need to know about normal temperature:

  • According to statistics, the most common normal body temperature is 37 o C, and not 36.6 o C, contrary to popular belief.
  • The norm is physiological fluctuations in thermometry readings during the day for the same person within 0.5 o C, or even more.
  • In the morning hours, lower readings are usually observed, while body temperature in the afternoon or evening can be 37 o C, or slightly higher.
  • In deep sleep, thermometry readings may correspond to 36 o C or less (as a rule, the lowest readings are observed between 4 and 6 o'clock in the morning, but a temperature of 37 o C or higher in the morning may indicate pathology).
  • The highest measurement data is often recorded from approximately 4 pm until night (for example, a constant temperature of 37.5 o C in the evening hours may be a normal variant).
  • In old age, normal body temperature may be lower, and its daily fluctuations are not so pronounced.
Whether an increase in temperature is a pathology depends on many factors. Thus, a prolonged temperature of 37 o C in a child in the evening is a variant of the norm, and the same indicators in an elderly person in the morning most likely indicate pathology.

Where can you measure body temperature:
1. IN armpit. Despite the fact that this is the most popular and simplest measurement method, it is the least informative. The results obtained can be influenced by humidity, room temperature and many other factors. Sometimes there is a reflex increase in temperature during measurement. This may be due to anxiety, for example, from a doctor's visit. When thermometry is performed in the oral cavity or rectum, such errors cannot occur.
2. In the mouth (oral temperature): its values ​​are usually 0.5 o C higher than those determined in the armpit.
3. In the rectum (rectal temperature): normally it is 0.5 o C higher than in the mouth and, accordingly, 1 o C higher than in the armpit.

Also quite reliable is the determination of temperature in ear canal. However, an accurate measurement requires a special thermometer, so this method is practically not used at home.

It is not recommended to measure oral or rectal temperature with a mercury thermometer; you should use an electronic device for this. For thermometry in infants, there are also electronic thermometers-pacifiers.

Do not forget that a body temperature of 37.1-37.5 o C may be associated with an error in measurements, or talk about the presence of pathology, for example, an infectious process in the body. Therefore, consultation with a specialist is still required.

Temperature 37 o C - is this normal?

If the thermometer shows 37-37.5 o C, don’t get upset or panic. Temperatures greater than 37 o C may be associated with measurement errors. To ensure accurate thermometry, the following rules must be observed:
1. The measurement should be carried out in a calm, relaxed state, no earlier than 30 minutes after physical activity (for example, in a child after active play temperature can be 37-37.5 o C and higher).
2. In children, measurements may be significantly elevated after screaming and crying.
3. It is better to carry out thermometry at approximately the same time, since low readings are more often observed in the morning, and in the evening the temperature usually rises to 37 o C and above.
4. When conducting thermometry in the armpit, it should be completely dry.
5. Where measurements are taken in the mouth (oral temperature), it should not be taken after eating or drinking (especially hot drinks), if the patient is short of breath or breathing through the mouth, or after smoking.
6. Rectal temperature may increase by 1-2 o C or more after physical activity or a hot bath.
7. Temperature 37 o C or slightly higher may be after eating, after physical activity, against a background of stress, anxiety or fatigue, after exposure to the sun, while in a warm, stuffy room with high humidity or, conversely, excessively dry air.

Another common cause of a temperature of 37 o C and above can always be a faulty thermometer. This is especially true for electronic devices, which quite often produce measurement errors. Therefore, when you receive high readings, determine the temperature of another family member - in case it will also be high. And it’s even better to always have a working mercury thermometer in the house for this case. When an electronic thermometer is still indispensable (for example, to determine the temperature of a small child), immediately after purchasing the device, take measurements with a mercury thermometer and an electronic one (for any healthy family member). This will make it possible to compare the results and determine the error in thermometry. When conducting such a test, it is better to use thermometers of different designs; you should not take the same mercury or electric thermometers.


4. Diseases of the reproductive system. When women have a temperature of 37-37.5 o C and pain in the lower abdomen, this may be a sign infectious diseases genital organs, for example, vulvovaginitis. A temperature of 37 o C and higher can be observed after procedures such as abortion, curettage. In men, fever may indicate prostatitis.
5. Diseases of the cardiovascular system. Infectious inflammatory processes in the heart muscle are often accompanied by low levels of fever. But despite this, they are usually accompanied by severe symptoms such as shortness of breath, disorders heart rate, swelling and a number of others.
6. Foci of chronic infection. They can be found in many organs. For example, if the body temperature is kept within 37.2 o C, then this may indicate the presence of chronic tonsillitis, adnexitis, prostatitis and other pathologies. After sanitization of the infectious focus, fever often goes away without a trace.
7. Children's infections. Often, a rash and a temperature of 37 o C or higher may be a symptom of chickenpox, rubella or measles. The rash usually appears at the height of the fever and may be accompanied by itching and discomfort. However, a rash can be a symptom of more serious diseases (blood pathology, sepsis, meningitis), so if it occurs, do not forget to call a doctor.

There are often situations when, after an infectious disease, the temperature remains at 37 o C or higher for a long time. This feature is often called a "temperature tail". Elevated temperature readings may persist for several weeks or months. Even after taking antibiotics against an infectious agent, a reading of 37 o C can remain for a long time. This condition does not require treatment and goes away on its own without a trace. However, if, along with a low-grade fever, cough, rhinitis or other symptoms of the disease are observed, this may indicate a relapse of the disease, complications, or indicate a new infection. It is important not to miss this condition, as it requires consultation with a doctor.

Other causes of low-grade fever in a child are often:

  • overheat;
  • reaction to preventive vaccination;
  • teething.
One of the common reasons for a child's temperature to rise above 37-37.5 o C is teething. In this case, thermometry data rarely reaches figures above 38.5 o C, so usually just monitoring the baby’s condition and using physical cooling methods is enough. Temperatures above 37 o C can be observed after vaccination. Usually the indicators are kept within the subfebrile range, and if they increase further, you can give the child a one-time antipyretic drug. An increase in temperature as a result of overheating can be observed in those children who are excessively wrapped and dressed. It can be very dangerous and cause heat stroke. Therefore, if the baby overheats, he should first be undressed.

Fever may occur with many non-infectious diseases. inflammatory diseases. As a rule, it is accompanied by others, quite characteristic features pathology. For example, a temperature of 37 o C and diarrhea streaked with blood may be symptoms of ulcerative colitis or Crohn's disease. In some diseases, such as systemic lupus erythematosus, low-grade fever may appear several months before the first signs of illness.

An increase in body temperature to low levels is often observed against the background of allergic pathology: atopic dermatitis, urticaria and other conditions. For example, shortness of breath with difficulty in exhaling, and a temperature of 37 o C or higher, can be observed during exacerbation of bronchial asthma.

Low-grade fever may occur with pathology the following systems organs:
1. The cardiovascular system:

  • VSD (syndrome vegetative dystonia) - a temperature of 37 o C and slightly higher may indicate sympathicotonia, and is often combined with high blood pressure, headaches and other manifestations;
  • high blood pressure and temperature 37-37.5 o C can occur with hypertension, especially during crises.
2. Gastrointestinal tract: a temperature of 37 o C or higher, and abdominal pain, may be signs of pathologies such as pancreatitis, non-infectious hepatitis and gastritis, esophagitis and many others.
3. Respiratory system: a temperature of 37-37.5 o C may accompany chronic obstructive pulmonary disease.
4. Nervous system:
  • thermoneurosis (habitual hyperthermia) – often observed in young women, and is one of the manifestations of vegetative dystonia;
  • spinal and brain tumors, traumatic injuries, hemorrhages and other pathologies.
5. Endocrine system: fever may be the first sign of increased function thyroid gland(hyperthyroidism), Addison's disease (insufficiency of adrenal cortex function).
6. Kidney pathology: a temperature of 37 o C and higher may be a sign of glomerulonephritis, dysmetabolic nephropathies, and urolithiasis.
7. Genital organs: low-grade fever can be observed with ovarian cysts, uterine fibroids and other pathologies.
8. Blood and immune system:
  • a temperature of 37 o C accompanies many immunodeficiency conditions, including oncology;
  • a slight low-grade fever can occur with blood pathologies, including common iron deficiency anemia.
Another condition in which the body temperature constantly remains at 37-37.5 o C is oncological pathology. In addition to low-grade fever, weight loss, loss of appetite, weakness, and pathological symptoms from various organs may also be observed (their nature depends on the location of the tumor).

Indicators of 37-37.5 o C are a variant of the norm after surgery. Their duration depends on the individual characteristics of the body and the volume of surgical intervention. A slight fever may also occur after some diagnostic procedures, such as laparoscopy.

Which doctor should I contact if I have an elevated body temperature?

Since an increase in body temperature can be due to a wide range of different reasons, the choice of a specialist to contact at a high temperature is determined by the nature of the other symptoms the person has. Let's consider which doctors should be contacted in various cases of increased body temperature:
  • If, in addition to fever, a person has a runny nose, pain, sore or sore throat, cough, headaches, aches in muscles, bones and joints, then it is necessary to contact general practitioner (), because we're talking about, most likely, about ARVI, colds, flu, etc.;
  • If you have a persistent cough for a long time, or a constant feeling of general weakness, or a feeling that it is difficult to breathe, or whistling when breathing, then you should consult a general practitioner and phthisiatrician (sign up), since these signs may be symptoms of either chronic bronchitis, either pneumonia or tuberculosis;
  • If elevated body temperature is combined with pain in the ear, leakage of pus or fluid from the ear, runny nose, scratchy, raw or sore throat, a feeling of mucus flowing down the back of the throat, a feeling of pressure, fullness or pain in the upper cheeks (cheekbones under the eyes) or above the eyebrows, then you should contact otolaryngologist (ENT) (make an appointment), since most likely we are talking about otitis media, sinusitis, pharyngitis or tonsillitis;
  • If elevated body temperature is combined with pain, redness of the eyes, photophobia, leakage of pus or non-purulent fluid from the eye, you should contact ophthalmologist (make an appointment);
  • If elevated body temperature is combined with pain when urinating, lower back pain, frequent urge to urinate, then you need to consult a urologist/ nephrologist (make an appointment) And venereologist (make an appointment), because a similar combination of symptoms may indicate either kidney disease or a sexually transmitted infection;
  • If elevated body temperature is combined with diarrhea, vomiting, abdominal pain and nausea, then you should contact infectious disease doctor (make an appointment), since such a set of symptoms may indicate an intestinal infection or hepatitis;
  • If elevated body temperature is combined with moderate abdominal pain, as well as various symptoms of dyspepsia (belching, heartburn, feeling of heaviness after eating, bloating, flatulence, diarrhea, constipation, etc.), then you should contact Gastroenterologist (make an appointment)(if there is none, then see a therapist), because this indicates organ diseases digestive tract(gastritis, peptic ulcer stomach, pancreatitis, Crohn's disease, etc.);
  • If elevated body temperature is combined with severe, unbearable pain in any part of the abdomen, then you should urgently contact surgeon (make an appointment), since this indicates a serious condition (for example, acute appendicitis, peritonitis, pancreatic necrosis, etc.) requiring immediate medical intervention;
  • If elevated body temperature in women is combined with moderate or mild pain in the lower abdomen, discomfort in the genital area, or unusual vaginal discharge, then you should contact gynecologist (make an appointment);
  • If elevated body temperature in women is combined with severe pain in the lower abdomen, bleeding from the genitals, severe general weakness, then you should urgently contact a gynecologist, since these symptoms indicate a serious condition (for example, ectopic pregnancy, uterine bleeding, sepsis, endometritis after abortion, etc.), requiring immediate treatment;
  • If elevated body temperature in men is combined with pain in the perineum and in the prostate gland, then you should contact a urologist, as this may indicate prostatitis or other diseases of the male genital area;
  • If elevated body temperature is combined with shortness of breath, arrhythmia, edema, then you should contact a therapist or cardiologist (make an appointment), since this may indicate inflammatory heart diseases (pericarditis, endocarditis, etc.);
  • If elevated body temperature is combined with joint pain, skin rashes, marbling of the skin, impaired blood flow and sensitivity of the extremities (cold hands and feet, blue fingers, feeling of numbness, goosebumps, etc.), red blood cells or blood in urine, pain when urinating or pain in other parts of the body, then you should contact rheumatologist (make an appointment), since this may indicate the presence of autoimmune or other rheumatic diseases;
  • Temperature in combination with rashes or inflammations on the skin and symptoms of acute respiratory viral infections may indicate various infectious or skin diseases(for example, erysipelas, scarlet fever, chickenpox, etc.), therefore, if such a combination of symptoms appears, you need to contact a therapist, infectious disease specialist and dermatologist (make an appointment);
  • If an elevated body temperature is combined with headaches, surges in blood pressure, or a feeling of interruptions in heart function, then you should consult a therapist, as this may indicate vegetative-vascular dystonia;
  • If elevated body temperature is combined with tachycardia, sweating, or enlarged goiter, then it is necessary to contact endocrinologist (make an appointment), as this may be a sign of hyperthyroidism or Addison's disease;
  • If elevated body temperature is combined with neurological symptoms(for example, obsessive movements, coordination disorder, deterioration of sensitivity, etc.) or loss of appetite, causeless weight loss, then you should contact oncologist (make an appointment), since this may indicate the presence of tumors or metastases in various organs;
  • Elevated temperature combined with very feeling unwell, which worsens over time, is a reason to immediately call an ambulance, regardless of what other symptoms the person has.

What studies and diagnostic procedures can doctors prescribe when body temperature rises to 37-37.5 o C?

Since body temperature can rise against the background of a wide range of different diseases, the list of studies that the doctor prescribes to identify the causes of this symptom is also very wide and variable. However, in practice, doctors do not prescribe the entire possible list of examinations and tests that could theoretically help identify the cause of elevated body temperature, but use only a limited set of certain diagnostic tests that with the maximum probability allow identifying the source of the temperature. Accordingly, for each specific case, doctors prescribe a different list of tests, which are selected in accordance with the accompanying symptoms that a person has in addition to elevated body temperature, and indicating the affected organ or system.

Since most often elevated body temperature is caused by inflammatory processes in various organs, which can be either infectious origin(for example, sore throat, rotavirus infection, etc.), and non-infectious (for example, gastritis, ulcerative colitis, Crohn's disease, etc.), then always if it is present, regardless of the accompanying symptoms, it is prescribed general analysis blood and a general urine test, allowing you to navigate in which direction the further diagnostic search should go and what other tests and examinations are necessary in each specific case. That is, in order not to prescribe a large number of studies of different organs, they first do a general blood and urine test, which allows the doctor to understand in which direction to “look” for the cause of the elevated body temperature. And only after identifying the approximate spectrum possible reasons temperature, other studies are prescribed to clarify the pathology that caused hyperthermia.

Indicators of a general blood test make it possible to understand whether the temperature is caused by an inflammatory process of infectious or non-infectious origin, or is not associated with inflammation at all.

So, if ESR is increased, then the temperature is caused by an inflammatory process of infectious or non-infectious origin. If the ESR is within normal limits, then the increased body temperature is not associated with the inflammatory process, but is caused by tumors, vegetative-vascular dystonia, endocrine diseases etc.

If, in addition to the accelerated ESR, all other indicators of a general blood test are within normal limits, then the temperature is due to a non-infectious inflammatory process, for example, gastritis, duodenitis, colitis, etc.

If a general blood test reveals anemia, and other indicators, except hemoglobin, are normal, then the diagnostic search ends here, since the elevated temperature is caused precisely by the anemic syndrome. In such a situation, anemia is treated.

A general urine test allows you to understand whether there is pathology of the urinary system. If there is one according to the analysis, then other studies are carried out in the future to clarify the nature of the pathology and begin treatment. If urine tests are normal, then to find out the cause of the elevated body temperature, the urinary system organs are not examined. That is, a general urine test will allow you to immediately identify the system in which the pathology caused an increase in body temperature, or, on the contrary, dismiss suspicions of diseases of the urinary tract.

Having determined from a general analysis of blood and urine the fundamental points, such as infectious or non-infectious inflammation in a person, or a non-inflammatory process at all, and whether there is pathology of the urinary organs, the doctor prescribes a number of other studies to understand which organ is affected. Moreover, this list of examinations is already determined by the accompanying symptoms.

Below we present options for lists of tests that a doctor may prescribe for elevated body temperature, depending on other accompanying symptoms a person has:

  • For a runny nose, sore throat, sore or raw throat, cough, headache, aching muscles and joints, usually only a general blood and urine test is prescribed, since such symptoms are caused by ARVI, flu, colds, etc. However, during an influenza epidemic, a blood test may be prescribed to detect the influenza virus to determine whether a person is dangerous to others as a source of influenza. If a person often suffers from colds, then he is prescribed immunogram (sign up)(total number of lymphocytes, T-lymphocytes, T-helpers, T-cytotoxic lymphocytes, B-lymphocytes, NK cells, T-NK cells, NBT test, assessment of phagocytosis, CEC, immunoglobulins of classes IgG, IgM, IgE, IgA ), to determine which parts of the immune system are not working correctly and, accordingly, what immunostimulants need to be taken to normalize the immune status and stop frequent episodes of colds.
  • At a temperature combined with a cough or a constant feeling of general weakness, or a feeling that it is difficult to breathe, or whistling when breathing, it is imperative to do x-ray chest(sign up) and auscultation (listen with a stethoscope) of the lungs and bronchi to determine whether a person has bronchitis, tracheitis, pneumonia or tuberculosis. In addition to x-rays and auscultation, if they do not give an accurate answer or their result is questionable, the doctor may prescribe sputum microscopy, determination of antibodies to Chlamydophila pneumoniae and respiratory syncytial virus in the blood (IgA, IgG), determination of the presence of mycobacterial DNA to distinguish between bronchitis, pneumonia and tuberculosis and Chlamydophila pneumoniae in sputum, bronchial washings or blood. Tests for the presence of mycobacteria in sputum, blood and bronchial washings, as well as sputum microscopy, are usually prescribed when tuberculosis is suspected (either asymptomatic persistent prolonged fever or fever with cough). But tests for determining antibodies to Chlamydophila pneumoniae and respiratory syncytial virus in the blood (IgA, IgG), as well as determining the presence of Chlamydophila pneumoniae DNA in sputum, are carried out to diagnose bronchitis, tracheitis and pneumonia, especially if they are frequent, long-lasting or untreatable antibiotics.
  • Temperature, combined with a runny nose, a feeling of mucus running down the back of the throat, a feeling of pressure, fullness or pain in the upper part of the cheeks (cheekbones under the eyes) or above the eyebrows, requires a mandatory x-ray of the sinuses (maxillary sinuses, etc.) (sign up) to confirm sinusitis, sinusitis or other type of sinusitis. In case of frequent, long-term sinusitis or that cannot be treated with antibiotics, the doctor may additionally prescribe the determination of antibodies to Chlamydophila pneumoniae in the blood (IgG, IgA, IgM). If the symptoms of sinusitis and elevated body temperature are combined with blood in the urine and frequent pneumonia, then the doctor may prescribe a test for antineutrophil cytoplasmic antibodies (ANCA, pANCA and cANCA, IgG) in the blood, since in such a situation systemic vasculitis is suspected.
  • If the elevated temperature is combined with a feeling of mucus running down the back wall of the throat, a feeling that cats are scratching in the throat, soreness and soreness, then the doctor prescribes an ENT examination, takes a smear from the oropharyngeal mucosa for bacteriological culture in order to determine the pathogenic microbes that caused inflammatory process. The examination is usually carried out without fail, but a swab from the oropharynx is not always taken, but only if a person complains of the frequent occurrence of such symptoms. In addition, if such symptoms appear frequently and do not go away even with antibiotic treatment, the doctor may prescribe the determination of antibodies to Chlamydophila pneumonia and Chlamydia trachomatis (IgG, IgM, IgA) in the blood, because these microorganisms can provoke chronic, often recurrent infectious and inflammatory diseases of organs respiratory system(pharyngitis, otitis, sinusitis, bronchitis, tracheitis, pneumonia, bronchiolitis).
  • If an elevated temperature is combined with pain, a sore throat, enlarged tonsils, the presence of plaque or white plugs in the tonsils, or a constantly red throat, then an ENT examination is required. If such symptoms persist for a long time or appear frequently, the doctor will prescribe a smear from the oropharyngeal mucosa for bacteriological culture, as a result of which it will become known which microorganism provokes the inflammatory process in the ENT organs. If the sore throat is purulent, then the doctor will definitely prescribe blood tests for the ASL-O titer in order to identify the risk of developing complications of this infection such as rheumatism, glomerulonephritis, myocarditis.
  • If the temperature is combined with pain in the ear, discharge of pus or any other fluid from the ear, then the doctor must conduct an ENT examination. In addition to the examination, the doctor most often prescribes bacteriological culture of ear discharge to determine which pathogen caused the inflammatory process. In addition, tests may be prescribed to determine antibodies to Chlamydophila pneumonia in the blood (IgG, IgM, IgA), to determine the titer of ASL-O in the blood, and to detect herpes virus type 6 in saliva, oropharyngeal scrapings, and blood. Tests for antibodies to Chlamydophila pneumonia and for the presence of herpes virus type 6 are performed to identify the microbe that causes otitis. However, these tests are usually prescribed only for frequent or long-term otitis media. A blood test for the ASL-O titer is prescribed only for purulent otitis in order to identify the risk of developing complications of streptococcal infection, such as myocarditis, glomerulonephritis and rheumatism.
  • If elevated body temperature is combined with pain, redness in the eye, as well as discharge of pus or other fluid from the eye, then the doctor must perform an examination. Next, the doctor may prescribe a culture of the discharge from the eye for bacteria, as well as a blood test for antibodies to adenovirus and IgE content (with particles of dog epithelium) in order to determine the presence of an adenovirus infection or allergy.
  • When elevated body temperature is combined with pain when urinating, lower back pain or frequent trips to the toilet, the doctor will first and without fail prescribe a general urine test, determination of the total concentration of protein and albumin in daily urine, urine test according to Nechiporenko (sign up), Zimnitsky test (sign up), and biochemical analysis blood (urea, creatinine). In most cases, these tests can determine whether you have kidney or urinary tract disease. However, if the above tests do not provide clarity, the doctor may prescribe cystoscopy Bladder(sign up), bacteriological culture of urine or scraping from the urethra to identify a pathogenic pathogen, as well as determination by PCR or ELISA of microbes in scraping from the urethra.
  • If you have an elevated temperature, combined with pain when urinating or frequent trips to the toilet, your doctor may order tests for various infections sexually transmitted diseases (for example, gonorrhea (sign up), syphilis (sign up), ureaplasmosis (sign up), mycoplasmosis (sign up), candidiasis, trichomoniasis, chlamydia (sign up), gardnerellosis, etc.), since such symptoms may also indicate inflammatory diseases of the genital tract. To test for sexually transmitted infections, your doctor may prescribe vaginal discharge, semen, prostate secretions, a urethral smear, and blood. In addition to tests, it is often prescribed Ultrasound of the pelvic organs (sign up), which allows us to identify the nature of changes occurring under the influence of inflammation in the genital organs.
  • With elevated body temperature, which is combined with diarrhea, vomiting, abdominal pain and nausea, the doctor first prescribes a stool test for scatology, a stool test for helminths, a stool test for rotavirus, a stool test for infections (dysentery, cholera, pathogenic strains of intestinal sticks, salmonellosis, etc.), stool analysis for dysbacteriosis, as well as scraping from the anal area for culture in order to identify the pathogenic pathogen that provoked the symptoms of intestinal infection. In addition to these tests, the infectious disease doctor prescribes blood test for antibodies to hepatitis A, B, C and D viruses (sign up), since such symptoms may indicate acute hepatitis. If a person, in addition to fever, diarrhea, abdominal pain, vomiting and nausea, also has yellowness of the skin and sclera of the eyes, then only blood tests for hepatitis (antibodies to hepatitis viruses A, B, C and D) are prescribed, since this indicates specifically about hepatitis.
  • If there is an elevated body temperature, combined with abdominal pain, symptoms of dyspepsia (belching, heartburn, flatulence, bloating, diarrhea or constipation, blood in the stool, etc.), the doctor usually prescribes instrumental studies and biochemical blood test. For belching and heartburn, a blood test for Helicobacter pylori and fibrogastroduodenoscopy (FGDS) (), which allows you to diagnose gastritis, duodenitis, gastric or duodenal ulcers, GERD, etc. For flatulence, bloating, periodic diarrhea and constipation, the doctor usually prescribes a biochemical blood test (activity of amylase, lipase, AST, ALT, alkaline phosphatase, concentration of protein, albumin, bilirubin), a urine test for amylase activity, a stool test for dysbacteriosis and scatology and Ultrasound of organs abdominal cavity(sign up), which allow you to diagnose pancreatitis, hepatitis, irritable bowel syndrome, biliary dyskinesia, etc. In complex and unclear cases or suspected tumor formations, the doctor may prescribe MRI (sign up) or x-ray of the digestive tract. If there are frequent bowel movements (3-12 times a day) with unformed feces, banded stools (feces in the form of thin ribbons) or pain in the rectum, then the doctor prescribes colonoscopy (make an appointment) or sigmoidoscopy (sign up) and stool analysis for calprotectin, which allows identifying Crohn's disease, ulcerative colitis, intestinal polyps, etc.
  • In case of elevated temperature in combination with moderate or mild pain in the lower abdomen, discomfort in the genital area, abnormal vaginal discharge, the doctor will definitely prescribe, first of all, a smear from the genital organs and an ultrasound of the pelvic organs. These simple studies will allow the doctor to determine what other tests are needed to clarify the existing pathology. In addition to ultrasound and smear on flora (), the doctor may prescribe tests for sexually transmitted infections ()(gonorrhea, syphilis, ureaplasmosis, mycoplasmosis, candidiasis, trichomoniasis, chlamydia, gardnerellosis, fecal bacteroids, etc.), to identify which vaginal discharge, scraping from the urethra or blood are donated.
  • At elevated temperatures, combined with pain in the perineum and prostate in men, the doctor will prescribe a general urine test, prostate secretion for microscopy (), spermogram (), as well as a smear from the urethra for various infections (chlamydia, trichomoniasis, mycoplasmosis, candidiasis, gonorrhea, ureaplasmosis, fecal bacteroides). In addition, the doctor may prescribe an ultrasound of the pelvic organs.
  • At a temperature combined with shortness of breath, arrhythmia and edema, it is imperative to do ECG(), chest x-ray, Ultrasound of the heart (sign up), as well as take a general blood test, a blood test for C-reactive protein, rheumatic factor and titer ASL-O (sign up). These studies allow us to identify the existing pathological process in the heart. If the studies do not clarify the diagnosis, the doctor may additionally prescribe a blood test for antibodies to the heart muscle and for antibodies to Borrelia.
  • If an elevated temperature is combined with skin rashes and symptoms of ARVI or flu, then the doctor usually prescribes only a general blood test and examines the rashes or redness on the skin in various ways (under a magnifying glass, under a special lamp, etc.). If there is a red spot on the skin that grows over time and is painful, the doctor will order an ASL-O titer test to confirm or deny erysipelas. If the skin rash cannot be identified during the examination, the doctor may take a scraping and prescribe it under microscopy to determine the type of pathological changes and the causative agent of the inflammatory process.
  • If the temperature is combined with tachycardia, sweating and enlarged goiter, you should do Ultrasound of the thyroid gland (), and also take a blood test for the concentration of thyroid hormones (T3, T4), antibodies to steroid-producing cells of the reproductive organs and cortisol.
  • When the temperature is combined with headaches, jumps blood pressure, a feeling of interruptions in the work of the heart, the doctor prescribes blood pressure monitoring, ECG, ultrasound of the heart, ultrasound of the abdominal organs, REG, as well as a general blood test, urine and biochemical blood test (protein, albumin, cholesterol, triglycerides, bilirubin, urea, creatinine , C-reactive protein, AST, ALT, alkaline phosphatase, amylase, lipase, etc.).
  • When the temperature is combined with neurological symptoms (for example, loss of coordination, deterioration of sensitivity, etc.), loss of appetite, causeless weight loss, the doctor will prescribe a general and biochemical blood test, a coagulogram, as well as an x-ray, Ultrasound of various organs (sign up) and, possibly, tomography, since such symptoms may be a sign cancer.
  • If the temperature is combined with pain in the joints, rashes on the skin, marbling of the skin, impaired blood flow in the legs and arms (cold hands and feet, numbness and a crawling sensation, etc.), red blood cells or blood in the urine and pain in other parts of the body, this is a sign of rheumatic and autoimmune diseases. In such cases, the doctor prescribes tests to determine whether a person has joint disease or an autoimmune pathology. Since the spectrum of autoimmune and rheumatic diseases is very wide, the doctor first prescribes X-ray of joints (sign up) and the following nonspecific tests: complete blood count, concentration C-reactive protein, rheumatoid factor, lupus anticoagulant, antibodies to cardiolipin, antinuclear factor, IgG antibodies to double-stranded (native) DNA, ASL-O titer, antibodies to nuclear antigen, antineutrophil cytoplasmic antibodies (ANCA), antibodies to thyroid peroxidase, presence of cytomegalovirus in the blood, Epstein-Barr virus, herpes viruses. Then, if the results of the listed tests are positive (that is, markers of autoimmune diseases are found in the blood), the doctor, depending on which organs or systems have clinical symptoms, prescribes additional tests, as well as X-rays, ultrasound, ECG, MRI, to assess the degree of activity of the pathological process.

Temperature 37-37.5 o C: what to do?

How to bring down the temperature to 37-37.5 o C? Reducing this temperature medicines not required. They are used only in cases of fever above 38.5 o C. The exception is an increase in temperature in late pregnancy, in young children who have previously had febrile convulsions, as well as in the presence of severe diseases of the heart, lungs, nervous system, the course of which may worsen against the background high fever. But even in these cases, it is recommended to reduce the temperature with medications only when it reaches 37.5 o C and above.

The use of antipyretic drugs and other methods of self-medication can complicate the diagnosis of the disease and also lead to unwanted side effects.

In all cases, the following recommendations must be followed:
1. Think: are you doing thermometry correctly? The rules for taking measurements have already been discussed above.
2. Try changing the thermometer to eliminate possible errors in measurements.
3. Make sure that this temperature is not normal. This is especially true for those who have not previously regularly measured their temperature, but have detected elevated data for the first time. To do this, you need to contact a specialist to exclude symptoms of various pathologies and order an examination. For example, if a temperature of 37 o C or slightly higher is constantly detected during pregnancy, and there are no symptoms of any diseases, this is most likely the norm.

If the doctor has identified any pathology leading to an increase in temperature to subfebrile levels, then the goal of therapy will be to treat the underlying disease. It is likely that after healing the temperature will return to normal.

In what cases should you contact a specialist immediately:
1. Low-grade body temperature began to rise to febrile levels.
2. Although the fever is mild, it is accompanied by other severe symptoms ( coughing, shortness of breath, chest pain, difficulty urinating, vomiting or diarrhea, signs of exacerbation of chronic diseases).

Thus, even a seemingly low temperature can be a sign of serious illness. Therefore, if you have any doubts about your condition, you should inform your doctor about them.

Prevention measures

Even if the doctor has not identified any pathology in the body, and a constant temperature of 37-37.5 o C is normal, this does not mean that nothing can be done at all. Long-term low-grade fevers are chronic stress for the body.

To gradually bring your body back to normal, you should:

  • promptly identify and treat foci of infection and various diseases;
  • avoid stress;
  • to refuse from bad habits;
  • follow a daily routine and get enough sleep;

Body temperature 37 - 37.5 - reasons and what to do about it?


Before use, you should consult a specialist.
  • Danger of high temperature

    A temperature of 37.0–37.9 is called subfebrile. An increase in indicators is a response of the immune system to the penetration of pathogenic microorganisms into the body. When pathogens remain in the body for a long time, severe intoxication develops - rashes appear on the skin, the functioning of the liver and kidneys is disrupted, since the organs have to intensively cleanse the body of toxic substances. At high temperatures, oxygen starvation occurs - the brain and heart suffer from oxygen deficiency, which negatively affects performance and the condition of the body as a whole.

    A slight increase in temperature is not the only sign of a cold or other illness. Hyperthermia is accompanied by cough, runny nose, cephalalgia, muscle and joint pain, weakness, vomiting and diarrhea. But colds, enterovirus and rotavirus infections rarely last more than a week. If low-grade fever is observed for a long time, it is necessary to undergo a thorough examination to establish the exact cause and begin treatment.

    Important! With prolonged hyperthermia, the human body gradually stops responding to elevated temperature values, all symptoms of the disease may disappear, but the pathological processes continue, the immune system is worn out. A crisis can come suddenly - the indicators will rise sharply, to a critical level, which will significantly worsen the patient’s condition.

    An increase in temperature every day for several weeks or a month to 37.2–37.5 degrees without other manifestations of disease is a sign of various serious infectious and non-infectious pathologies.

    Natural

    One of the most common causes of hyperthermia is measurement errors. Cheap electronic thermometers often break down and show incorrect values. Not immune from errors and mercury thermometers. Therefore, if prolonged hyperthermia without symptoms is observed, it is necessary to measure with another device.

    Reasons for natural temperature rise:

    • normal state - moderate hyperthermia in many people is observed constantly throughout life, while all other health indicators are normal, often such an anomaly is inherited;
    • rapid metabolism - the body produces a lot of energy, which provokes an increase in temperature values;
    • heat, dry and hot air in the room - the temperature rises due to a violation of heat transfer, most often this condition occurs in a small child;
    • overheating, long flight;
    • stress, fear - adrenaline increases temperature values;
    • intense physical activity;
    • prolonged overwork is a protective reaction of the body; most people, when their temperature rises, try to stay in bed for at least a few days, which allows them to regain strength;
    • overeating, hangover syndrome;
    • in women, temperature indicators are affected by the phase menstrual cycle– an increase in values ​​up to 37.1–37.3 can be observed before ovulation;
    • in young children, hyperthermia is observed during teething, after vaccinations, in adolescents - during hormonal changes body.

    A prolonged increase in temperature to 37.1–37.4 after an acute respiratory viral infection or flu is called a temperature tail or train - this condition is normal, harmless, and goes away on its own without additional treatment within 5–7 days. But if the problem does not disappear for the second week after the illness, a secondary bacterial infection may have occurred, and you need to get tested.

    Causes associated with diseases

    Important! The temperature in the evening is usually a few tenths of a degree higher than in the morning or afternoon.

    An increase in temperature over several weeks or months is a sign of an inflammatory process. The body constantly produces antibodies to fight pathogens.

    A prolonged increase in temperature can be caused by caries, long-term non-healing ulcers in diabetics, allergies, and sexually transmitted diseases.

    • hormonal changes during pregnancy and breastfeeding - most often the values ​​rise to 37.3–37.6 in the first trimester, after childbirth, the problem does not require drug therapy if the tests are normal;
    • ectopic pregnancy, ovarian cyst, disturbances in the functioning of female and male genital organs;
    • the presence of malignant tumors in the body - prolonged hyperthermia is often one of the first symptoms of cancer; it is necessary to urgently visit a doctor;
    • autoimmune diseases - dysfunction immune system, in which the body attacks not only foreign, but its own cells;
    • diseases of the thyroid gland - its hormones take part in the process of thermoregulation, an increase in their number leads to a rapid heartbeat, weight loss, a person does not tolerate heat well, his hair condition worsens;
    • fluctuations in adrenal hormone levels;
    • anemia - a problem that often occurs in women and children with a lack of iron, internal bleeding, is characterized by a decrease in the level of hemoglobin in the blood.

    An increase in temperature is often observed with long-term use of antibiotics. penicillin group, antipsychotics, antidepressants, muscle relaxants, antihistamines, narcotic painkillers, oral contraceptives.

    Important! In infants up to 12 months, low-grade fever (up to 37.2 degrees) is considered normal; the indicators normalize by the beginning of the second year.

    Since there are many reasons for prolonged low-grade fever, in order to establish the true cause, you will have to visit many doctors, take various tests. Clinical analysis blood allows you to determine whether hyperthermia is caused by infectious or non-infectious pathologies. The presence of an inflammatory process is indicated by an increase in ESR. An increased erythrocyte sedimentation rate in combination with a high content of monocytes, lymphocytes, and leukocytes indicates the presence of viral diseases. An increase in the number of eosinophils may indicate helminthic infestation, and leukocytosis with neutrophilia occurs with a bacterial infection.

    To identify the cause of a prolonged increase in temperature, you must first visit a therapist or pediatrician. Based on examination, history taking, primary diagnosis he will give a referral to other specialists. An infectious disease specialist, an immunologist, an endocrinologist, a urologist, a gastroenterologist, and a phthisiatrician can treat low-grade fever. In some cases, consultation with a neurologist, psychotherapist, or oncologist may be required.

    Important! Due to some anatomical and hormonal features, the normal temperature in men is always slightly higher than in women.

    At long-term low-grade fever self-medication is dangerous and useless, since it can distort clinical picture. Assign necessary medications Only a doctor can do this after identifying the causes of the temperature increase.

    What you can do at home:

    • drink more liquid - clean water, herbal decoctions, fruit drinks, natural juices;
    • normalize your daily routine, get enough sleep;
    • avoid stress, use relaxing practices;
    • take vitamins, eat right, avoid junk food and alcohol, reduce salt intake and caffeinated drinks;
    • strengthen the immune system - carry out hardening procedures, walk more fresh air, exercise.

    At temperatures up to 38–38.5 degrees, you should not take antipyretics - the body, with the help of hyperthermia, tries to cope with the microbes on its own. Natural immunomodulators such as tincture of echinacea, eleutherococcus, and ginseng should also be used with caution. For many diseases, even such harmless remedies are contraindicated; you need to carefully read the instructions.

    A prolonged or constant increase in temperature above 37 degrees is a reason to consult a doctor, even if you generally feel good and have no symptoms of disease. Low-grade fever is often caused by non-dangerous reasons, but can sometimes be the first sign of serious, fatal diseases.

    Weakness, runny nose, sore throat, persistent temperature of 37 - signs of a cold, known to everyone. This list can be supplemented and expanded, but in general it is repeated from time to time to one degree or another.

    By the way, why does the temperature stay at 37.5 degrees when you have a cold, which you don’t always notice? This is the body’s protective reaction to the presence of foreign bacteria and viruses that need to be neutralized.

    A temperature of 37.1, a temperature of 37.2, a temperature of 37.3 with a cold most likely indicates an inflammatory process, but in some cases this may be a consequence of overwork. It is important to have data on other symptoms, then it will be possible to accurately determine the cause and prescribe effective treatment. By the way, it will be possible to talk about its effectiveness only after complete recovery. If treatment leads to relapse, it means it is ineffective.

    Let's talk about some common mistakes that are made when treating a cold with a temperature of 37 degrees, runny nose, sore throat and other accompanying “joys”:

    • You should not grab aspirin and other antipyretics immediately after a temperature of 37.1 with a cold has made itself felt. The natural course of recovery should not be disrupted by premature medical intervention. By lowering the temperature, you disrupt the natural resistance of the immune system to the disease.
    • If a cold has a temperature of 37, this does not mean that the disease is not serious and is in no way related to the flu. Today there are many different types of influenza virus infection known, and not all of them occur with a fever of 39 and above.
    • If lozenges, tablets and other pharmaceutical products do not help with a sore throat, you should not grab vodka with pepper (one of the popular folk recipes) or eat a plate of freshly chopped onions, flavored with the same fresh garlic. Phytoncides and alcoholic heating can be useful, but only in strictly defined doses. Otherwise, you will burn the mucous membranes of your throat, esophagus and stomach. This will not save you from acute respiratory infections, but it can lead to other, no less serious consequences.
    • A temperature of 37 with a cold lasts a week - do not rush to buy immunomodulators. There are no indisputable scientific evidence something that gives a lasting positive effect and reduces the incidence of acute respiratory infections. Lately they have been talking about this more and more often, but, of course, wide publicity of this information is completely unprofitable for the manufacturers of these drugs. Therefore, be careful when choosing medications. Do not expect anything from the drug that is not indicated in its instructions for use.
    • Bed rest is the first commandment of a quick recovery. When you have a cold with a temperature of 37, pretending that you can survive the illness on your feet is absolutely wrong. This can lead to the disease going deeper: into the lungs and bronchi. A temperature of 37.2 for a cold, a temperature of 37.3 for a cold are not normal, and treatment must be completed.

    The more complete information We know about the course of the disease, the easier it is for us to choose the right path to fight it. By how long the temperature stays at 37 for a cold, and how it changes later, you can understand how successfully the body fights the disease.

    Let us remind you again. A typical set of signs of a cold is a temperature of 37.5 degrees, constant weakness, runny nose, and there is no clear plan on what to do and how to treat a cold that has overtaken you. Don't rush to empty the pharmacy, there may be effective means and methods that you have not yet tried.

    Forcis is your amulet against acute respiratory infections and ARVI

    Nobody likes to be sick. With a cold on your lip, a temperature of 37 degrees and a runny nose, it is difficult to feel like an active and joyful person. Our mood and attitude directly depend on our well-being. And such signs as malaise, temperature 37.4, and in general may indicate the presence of influenza or another serious virus.

    And often after suffering from an illness, we assure ourselves that from Monday we will start drinking freshly squeezed juices, eating onions and garlic every day and generally strengthening our immunity. However, if you look at things soberly and do not make impossible promises, start preventing acute respiratory infections by regularly taking the drug Forcis. These are lozenges based on a natural complex of polyphenols that stand between you and pathogenic bacteria, viruses and microbes. With a temperature of 37.5 for a cold, take foot baths and drink herbal infusions not enough for recovery at all. Your body needs more specific help. If you don’t know what to drink for a cold with a temperature of 37, start treatment with Forcys. This drug.

    A body temperature of 37.3 °C is considered subfebrile, that is, not reaching the level of fever. It may appear when various diseases in adults and children, being one of the signs of inflammation. But situations often occur when a thermometer reading of 37.3 °C is found in a completely healthy person. That is why a single detection of low-grade fever is not a cause for alarm. It is taken into account if repeated measurements after a few hours give the same result. In this case, not only a constant temperature is important, but also its repeated rises. They can be detected either within one day or over several days.

    Reasons for the temperature increase to 37.3 °C

    Infectious and inflammatory diseases. Of course, the most common reason temperature 37.3 °C – infectious process. More than 80% of cases in everyday life medical practice are caused by it. And the dominant place in the list of all possible infections is occupied by the group of acute respiratory infections (acute respiratory diseases, mainly of a viral nature). They are seasonal and pose an epidemic danger. Acute respiratory infections can be caused by influenza viruses, parainfluenza, rhino-, corona- and adenoviruses and some other less common pathogens. Symptoms that develop in this case include signs of intoxication (headache, malaise, muscle and joint pain, rapid heartbeat, general weakness), fever, catarrhal symptoms (runny nose, discomfort and sore throat, cough due to irritation back wall pharynx). The severity of each symptom depends on the type of pathogen and the individual characteristics of the sick person.

    Other infectious and inflammatory diseases can also lead to an increase in temperature to 37.3 °C. Most often, sinusitis and other sinusitis, pyelonephritis, cystitis, and bronchopulmonary pathology are diagnosed. Purulent inflammation of the skin (or mucous membranes) is also possible.

    Non-communicable diseases. TO non-infectious causes temperature rises include systemic diseases(rheumatism, rheumatoid arthritis and others). An increase in temperature to 37.3 °C is possible with overheating and heat stroke, in the early recovery period after operations, or traumatic brain injuries. In women, a rise in temperature is often observed after ovulation and during pregnancy.

    Is a temperature of 37.3 °C dangerous?

    Increased body temperature is universal defensive reaction the body in response to infection and the development of inflammation of any origin and location. It creates unfavorable conditions for the development and activity of some microorganisms harmful to humans.

    However, this condition is usually not dangerous for our body. A temperature of 37.3 °C does not lead to the deactivation of key enzymes, does not contribute to the deformation of protein molecules and does not cause cell death. And although it is often accompanied by a feeling of malaise, vital organs are not affected. Even sensitive and delicate ones are not damaged nerve cells brain. Therefore, it is a mistake to assume that a temperature of 37.3 °C always poses some kind of danger for a sick person, even if he feels unwell.

    Is it possible to reduce the temperature to 37.3 °C and how to do it?

    A thermometer reading of 37.3 °C is not a reason for the active use of various medications and non-medicinal measures to combat elevated temperature. Such “treatment” will not necessarily be beneficial, although it may temporarily improve your well-being. So you shouldn’t take antipyretic drugs; it’s better to give the body the opportunity to make the most of its natural defense mechanisms.

    It is possible to bring down a temperature of 37.3 °C with severe intoxication, the risk of developing cardiac and neurological complications, and a tendency to rapid deterioration of the condition with the development of a subjectively poorly tolerated fever. All these conditions require prompt consultation with a doctor and comprehensive treatment, one of the components of which will be taking medications with antipyretic and anti-inflammatory effects. Non-drug measures can be used in consultation with your doctor.

    Often it is necessary not only to reduce the temperature, but also to reduce the severity catarrhal symptoms and intoxication. In this situation, you can use complex action products, one of which is RINZA®.

    Temperature 37.3 °C in a child

    A child's temperature of 37.3 °C does not always indicate the presence of a disease. This condition requires analyzing the situation and determining its true cause. What to do if a child’s temperature is 37.3 °C? First of all, give up the desire to immediately give him an age-appropriate antipyretic drug. Other presenting symptoms need to be assessed.

    For example, a cough accompanying a temperature of 37.3 °C in a child may be a sign of inflammation of the back wall of the pharynx, damage to the larynx, or involvement of the lungs in the process.
