Increased body temperature. Causes of high body temperature

To assess the condition of a person with a high temperature, let's find out why this happens to the body.

Normal body temperature

The normal human temperature is on average 36.6 C. This temperature is optimal for the biochemical processes occurring in the body, but each organism is individual, so it is possible to consider a temperature from 36 to 37.4 C normal for some individuals (we are talking about a long-term condition and in if there are no symptoms of any disease). In order to make a diagnosis of habitually elevated temperature, you need to be examined by a doctor.

Why does body temperature rise

In all other situations, an increase in body temperature above normal indicates that the body is trying to fight something. In most cases, these are foreign agents in the body - bacteria, viruses, protozoa or a consequence physical impact on the body (burn, frostbite, foreign body). At elevated temperatures, the existence of agents in the body becomes difficult; infections, for example, die at a temperature of about 38 C.

But any organism, like a mechanism, is not perfect and can malfunction. In the case of temperature, we can observe this when the body, due to individual characteristics immune system reacts too violently to various infections, and the temperature rises too high, for most people this is 38.5 C. But again for children and adults who have had early febrile seizures at high temperatures (if you don’t know, ask your parents or your doctor, but usually this is not forgotten, as it is accompanied by a short-term loss of consciousness) the critical temperature can be considered 37.5-38 C.

Complications of elevated temperature

If the temperature is too high, disturbances occur in the transmission of nerve impulses, and this can lead to irreversible consequences in the cerebral cortex and subcortical structures until breathing stops. In all cases of critically high temperature, antipyretic drugs are taken. All of them affect the thermoregulation center in the subcortical structures of the brain. Helper Methods, and this, first of all, wiping the surface of the body with warm water is aimed at increasing blood flow on the surface of the body and promoting the evaporation of moisture, which leads to a temporary and not very significant decrease in temperature. Rubbing with a weak solution of vinegar on modern stage After the research, it is considered inappropriate since it has exactly the same results as just warm water.

A prolonged increase in temperature (more than two weeks), despite the degree of increase, requires examination of the body. During which the cause should be clarified or a diagnosis of habitually low-grade fever should be made. Be patient and contact several doctors with the results of the examination. If the results of tests and examinations do not reveal any pathology, do not measure your temperature again without showing any symptoms, otherwise you risk developing psychosomatic diseases. Good doctor I must answer you exactly why you constantly have a low-grade fever (37-37.4) and whether anything needs to be done. There are a great many reasons for a long-term elevated temperature, and if you are not a doctor, do not even try to diagnose yourself, and it is impractical to occupy your head with information that you do not need at all.

How to measure temperature correctly.

In our country, probably more than 90% of people measure their body temperature at armpit.

The armpit should be dry. Measurements are made in calm state 1 hour after any physical activity. It is not recommended to drink hot tea, coffee, etc. before taking measurements.

All this is recommended when clarifying the existence of a long-term high temperature. In emergency cases, if there are complaints about bad feeling measurements are carried out under any conditions. Mercury, alcohol, and electronic thermometers are used. If you have doubts about the correctness of the measurements, measure the temperature of healthy people and take another thermometer.

When measuring the temperature in the rectum, a temperature of 37 degrees C should be considered normal. Women should consider their menstrual cycle. It is normal for the temperature in the rectum to rise to 38 degrees C during the period of ovulation, which is days 15-25 of a 28-day cycle.

Measurement in oral cavity I consider it inappropriate.

Recently, ear thermometers have appeared on sale and are considered the most accurate. When measuring in the ear canal, the norm is the same as when measuring in the armpit. But young children usually react nervously to the procedure.

The following conditions require calling an ambulance:

A. In any case, at a temperature of 39.5 and above.

b.High temperature is accompanied by vomiting, blurred vision, stiffness of movements, muscle tension in the cervical spine spine (impossible to tilt the chin to the sternum).

V. High temperature is accompanied by severe abdominal pain. Especially in the elderly, even with moderate abdominal pain or fever, I advise you to call an ambulance.

d. In a child under ten years of age, the temperature is accompanied by a barking, dry cough, and difficulty breathing. There is a high probability of developing inflammatory narrowing of the larynx, the so-called laryngotracheitis or false croup. The algorithm of actions in this case is to humidify the inhaled air, trying not to scare, calming, take the child to the bathroom to pour hot water To obtain steam, inhale humidified, but of course not hot air, so being at least 70 centimeters from hot water. If there is no bathroom, an improvised tent with a source of steam. But if the child still gets scared and does not calm down, then stop trying and just wait for an ambulance.

d. A sharp rise in temperature over 1-2 hours above 38 degrees C in a child under 6 years of age who has previously experienced convulsions at high temperatures.
The algorithm of action is to give an antipyretic (dosages must be agreed in advance with the pediatrician or see below), call an ambulance.

In what cases should you take an antipyretic drug to reduce body temperature:

A. Body temperature is above 38.5 degrees. C (if there is a history of febrile convulsions, then at a temperature of 37.5 degrees C).

b At a temperature below the above figures only in the case of severe symptoms in the form of a headache, a feeling of aches throughout the body, and general weakness. significantly interferes with sleep and rest.

In all other cases, you need to allow the body to take advantage of the increased temperature, helping it remove the so-called infection-fighting products. (dead leukocytes, macrophages, remnants of bacteria and viruses in the form of toxins).

I will give you my preferred herbal folk remedies.

Folk remedies for fever

A. In first place are fruit drinks with cranberries - take as much as your body requires.
b. Fruit drinks from currants, sea buckthorn, lingonberries.
V. Any alkaline mineral water with a low percentage of mineralization or just clean boiled water.

The following plants are contraindicated for use at elevated body temperatures: St. John's wort, golden root (Rhodiola rosea).

In any case, if the temperature rises for more than five days, I recommend consulting a doctor.

A. The onset of the disease, when did the elevated temperature appear and can you associate its appearance with anything? (hypothermia, increased physical activity, emotional stress).

b. Have you had any contact with people with fever in the next two weeks?

V. Have you had any illness with fever in the next two months? (remember, you may have suffered some kind of ailment “on your feet”).

d. Have you had a tick bite this season? (it is appropriate to remember even the contact of a tick with the skin without a bite).

d. It is very important to remember if you live in areas where hemorrhagic fever with renal syndrome (HFRS) is endemic, and these are areas Far East, Siberia, Urals, Volgovyatka region, whether there was contact with rodents or their waste products. First of all, fresh excrement is dangerous, since the virus is contained in it for a week. The latent period of this disease is from 7 days to 1.5 months.

e. Indicate the nature of the manifestation of increased body temperature (absorbent, constant, or with a gradual increase at a certain time of the day).

h. Check whether you received vaccinations within two weeks.

and. Tell your doctor clearly what other symptoms accompany high body temperature. (catarrhal - cough, runny nose, pain or sore throat, etc., dyspeptic - nausea, vomiting, abdominal pain, loose stool etc.)
All this will allow the doctor to prescribe examinations and treatment in a more targeted and timely manner.

Over-the-counter medications used to reduce body temperature.

1. paracetamol in various names. Single dosage for adults: 0.5-1 g. daily up to 2 g. the period between doses is at least 4 hours, for children 15 mg per kilogram of the child’s weight (for information, 1 gram is 1000 mg). For example, a child weighing 10 kg requires 150 mg - in practice, this is a little more than half a tablet of 0.25 grams. It is available both in tablets of 0.5 g and 0.25 g, and in syrups and rectal suppositories. Can be used from infancy. Paracetamol is included in almost all combined cold medicines(Fervex, Theraflu, Coldrex).
For infants, it is better to use it in rectal suppositories.

2. Nurofen (ibuprofen) adult dosage 0.4g. , children's 0.2 g Recommended for children with caution; used in children with intolerance or weak effect of paracetamol.

3. nise (nimesulide) is available in both powders (nimesil) and tablets. Adult dosage 0.1g...for children 1.5 milligrams per kilogram of a child’s weight, that is, with a weight of 10 kg, 15 mg is required. A little more than one tenth of a tablet. Daily dosage no more than 3 times a day

4. Analgin - adult 0.5 g...children 5-10 mg per kg of child’s weight That is, with 10 kg of weight, a maximum of 100 mg is required - this is a fifth of the tablet. Daily allowance up to three times a day. Not recommended for frequent use by children.

5. Aspirin - adult single dosage 0.5-1 g. Daily dose up to four times a day, contraindicated for children.

At elevated temperatures, all physical procedures are canceled, water treatments, mud therapy, massage.

Diseases that occur with a very high (above 39 degrees C) temperature.

Flu - viral disease, accompanied by a sharp rise in temperature, severe aching joints and muscle pain. Catarrhal symptoms (runny nose, cough, sore throat, etc.) appear on the 3rd-4th day of illness, and with a normal ARVI, first the symptoms of a cold, then a gradual rise in temperature.

Sore throat – severe pain in the throat when swallowing and at rest.

Varicella (chickenpox), measles They can also begin with a high temperature and only on days 2-4 the appearance of a rash in the form of vesicles (bubbles filled with liquid).

Pneumonia (lung inflammation) Almost always, except for patients with reduced immunity and the elderly, it is accompanied by high fever. Distinctive feature, the appearance of pain in chest, aggravated by deep breathing, shortness of breath, dry cough at the beginning of the disease. All these symptoms are in most cases accompanied by a feeling of anxiety and fear.

Acute pyelonephritis(inflammation of the kidneys), along with high temperature, pain in the projection of the kidneys comes to the fore (just below the 12th ribs, with irradiation (rebound) to the side, often on one side. Swelling on the face, increased arterial pressure. The appearance of protein in urine tests.

Acute glomerulonephritis, the same as pyelonephritis only with the involvement of the pathological reaction of the immune system in the process. Characterized by the appearance of red blood cells in urine tests. Compared to pyelonephritis, it has a higher percentage of complications and is more prone to becoming chronic.

Hemorrhagic fever with renal syndrome- an infectious disease transmitted from rodents, mainly from voles. It is characterized by a decrease, and sometimes complete absence urination in the first days of illness, redness skin, severe muscle pain.

Gastroenterocolitis(salmonellosis, dysentery, paratyphoid fever, typhoid fever, cholera, etc.) The main dyspeptic syndrome is nausea, vomiting, loose stools, abdominal pain.

Meningitis and encephalitis(including tick-borne) - inflammation meninges infectious nature. The main syndrome is meningeal - severe headaches, blurred vision, nausea, tension in the neck muscles (it is impossible to bring the chin to the chest). Meningitis is characterized by the appearance of pinpoint hemorrhagic rashes on the skin of the legs and the anterior wall of the abdomen.

Viral hepatitis A– the main symptom is “jaundice”, the skin and sclera become icteric in color.

Diseases occurring with moderately elevated body temperature (37-38 degrees C).

Exacerbations chronic diseases, such as:

Chronic bronchitis, complaints of cough, both dry and with sputum, shortness of breath.

Bronchial asthma infectious-allergic nature - complaints of nighttime, sometimes daytime attacks of lack of air.

Pulmonary tuberculosis, complaints of prolonged cough, severe general weakness, sometimes streaks of blood in the sputum.

Tuberculosis of other organs and tissues.

Chronic myocarditis, endocarditis, is characterized by prolonged pain in the heart area, arrhythmic uneven heartbeat

Chronic pyelonephritis.

chronic glomerulonephritis - the symptoms are the same as in acute ones, only less pronounced.

Chronic salpingoopharitis - gynecological disease which is characterized by pain in the lower abdomen, discharge, and pain when urinating.

The following diseases occur with low-grade fever:

Viral hepatitis B and C, complaints of general weakness, joint pain, late stages“jaundice” joins.

Diseases of the thyroid gland (thyroiditis, nodular and diffuse goiter, thyrotoxicosis) main symptoms are a feeling of a lump in the throat, rapid heartbeat, sweating, irritability.

Acute and chronic cystitis, complaints of painful urination.

Acute and exacerbation chronic prostatitis, a male disease characterized by difficult and often painful urination.

Sexually transmitted diseases, such as gonorrhea, syphilis, as well as opportunistic (may not manifest as a disease) urogenital infections - toxoplasmosis, mycoplasmosis, ureoplasmosis.

A large group of cancer diseases, one of the symptoms of which may be a slightly elevated temperature.

Basic tests and examinations that can be prescribed by a doctor if you have a long-term low-grade fever (increased body temperature within 37-38 degrees C).

1. Full analysis blood - allows you to judge by the number of leukocytes and the value of ESR (erythrocyte sedimentation rate) whether there is any inflammation in the body. The amount of hemoglobin can indirectly indicate the presence of diseases gastrointestinal tract.

2. A complete urine test indicates the condition of the urinary system. First of all, the number of leukocytes, red blood cells and protein in the urine, as well as specific gravity.

3. Biochemical analysis blood (blood from a vein):. CRP and rheumatoid factor - their presence often indicates hyperactivity of the body's immune system and manifests itself in rheumatic diseases. Liver tests can diagnose hepatitis.

4. Markers of hepatitis B and C are prescribed to exclude corresponding viral hepatitis.

5. HIV- to exclude acquired immunodeficiency syndrome.

6. Blood test for RV - to detect syphilis.

7. Mantoux reaction, respectively, tuberculosis.

8. A stool test is prescribed for suspected diseases of the gastrointestinal tract and helminthic infestation. Positive hidden blood a very important diagnostic sign in the analysis.

9. A blood test for thyroid hormones should be done after consulting an endocrinologist and examining the thyroid gland.

10. Fluorography – even without diseases, it is recommended to undergo it once every two years. It is possible to prescribe FLG by a doctor if pneumonia, pleurisy, bronchitis, tuberculosis, or lung cancer are suspected. Modern digital fluorographs make it possible to make a diagnosis without resorting to extensive radiography. Low dose is used accordingly X-ray exposure and only in unclear cases additional examinations with an x-ray and tomograph are required. Magnetic resonance imaging is considered the most accurate.

11 Ultrasound of internal organs and the thyroid gland is performed to diagnose diseases of the kidneys, liver, pelvic organs, and thyroid gland.

12 ECG, ECHO KG, to exclude myocarditis, pericarditis, endocarditis.

Tests and examinations are prescribed by the doctor selectively, based on clinical need.

Accompanied by an increase in temperature. In turn, this causes panic among parents. Especially if the child is still very small. Your temperature may rise even if the weather changes, you are tired, or you are stressed. Before giving him antipyretic medications or using other methods to bring down the temperature, it is necessary to determine the cause of the fever. In some cases, you need to call a doctor immediately.

What is the normal temperature for a child?

In adults, the normal body temperature is 36.6°C. In contrast, in children the normal temperature ranges from 36-37°C. Infants have an elevated temperature by an average of 0.3-0.4°C. During the first three months of life, the baby's body temperature depends on external environment, from a child's sleep. A daily fluctuation of 0.6°C is considered optimal. For older children, the run-up should not exceed 1°C during the day. Up to 5 years of age, a child’s temperature may rise to 37°C. In the absence of cough and runny nose, this is not considered a deviation from the norm. Try it on in the morning after the child has woken up and lay in bed for a while. Most likely everything will be fine.

Temperature is measured using thermometers. They are mercury, electronic and infrared.

Mercury thermometers are more accurate. The measurement error is 0.1 degrees. The measurement is taken in the armpit for 7 minutes or in the rectum for 5 minutes. This thermometer is dangerous because it contains mercury and can be broken or crushed.

Electronic ones are easy to use. Temperature is measured in the mouth, armpit, or rectum. After 3 minutes the thermometer will show the result. After the measurement, a beep sounds. Electronic thermometers in the form of a pacifier are sold for infants. After 4 minutes, such a thermometer will show the baby’s body temperature. The error of such a thermometer is much greater than that of a mercury thermometer: up to 1 degree.

The infrared thermometer is non-contact and ear-mounted. An ear thermometer can easily measure your temperature. Measurement time 5 seconds. But he has enough high price. Non-contact shows the temperature when you bring it to the skin. They do not have high accuracy. It makes it easy to control temperature fluctuations.

Causes of high temperature in a child

In the human brain there is a center responsible for thermoregulation. When it is irritated, heat transfer decreases. An increase in temperature is a protective reaction of the body.

During infections, bacteria enter the body, multiply and release toxic substances. Blood cells - white blood cells - fight harmful bacteria. When the temperature jumps to 39.5°C, the proliferation of microorganisms slows down. When the virus multiplies rapidly, the child develops a high fever.

If there is no infection in the body, then the causes of fever may be immune reactions. For example: injuries, burns, allergic diseases, psychological disorders.

Children easily overheat in hot weather, which can cause a rise in temperature. In infants, overheating often occurs due to wrapping when going to bed. When overheated, the baby becomes moody or lethargic. In hot weather, the child should be moved to the shade. Undress and give plenty of fluids. Wipe with water. Within an hour, the temperature should decrease without the use of medication.

The cause of fever may be. In this case, the thermometer readings do not exceed 38°C. The child puts everything in his mouth, his gums become inflamed. 1-3 days after the tooth appears, the temperature subsides.

In infants, it is difficult for parents to examine their throat. He himself cannot explain what worries him. Therefore there is no fever severe symptoms can be observed in several diseases.

Is it possible to lower a child's temperature?

During fever, the body's defenses are activated. The process of tissue restoration is accelerated. At temperatures above 37°C, the body fights the infection and there is no point in fighting it off. Heat means good. At the same time, interferon is produced in the body. It kills germs. On the second or third day of illness, the amount of interferon in the blood is maximum. If even with a slight fever the parents gave the child an antipyretic, the illness lasts longer. Recovery occurs around the seventh day.

Children's bodies are different. In some cases, babies do not tolerate even a slight increase in temperature. If the child plays calmly at high temperatures, then there is no need to worry too much. If there is a change in the baby’s behavior, when he experiences discomfort with a fever, or is capricious, you should consult a doctor. Some children may have seizures. If you have a disease of the heart, kidneys, or lungs, fever can cause deterioration in the functioning of these organs. In this case, you should not rely general recommendations, but listen to the doctor’s advice.

What temperature to lower in a child

For some parents, it is enough to touch their lips to the baby's forehead to understand that the child has a fever. A slight increase in temperature does not mean a mild cold. With pneumonia, the temperature may not exceed 38°C, and with ARVI, it can rise to 40°C. In any case, it is worth calling a doctor to clarify the diagnosis. If the thermometer shows more than 38.5°C, start reducing the fever without waiting for the doctor. In infants up to three months, the temperature is reduced to 38°C.

You should not wrap your child up. It must have heat dissipation. The room should not be too hot. It's better to ventilate the room. The child should be given plenty of fluids to drink to avoid thickening of the blood and causing sweating.

Dry mouth, refusal to eat, and excessive crying mean that an antipyretic should be given.

How to reduce a child's temperature

When a child has a fever, the baby needs to replenish fluid loss. They come out with urine pathogenic microbes. Warm water should be given half a glass every half hour. If the baby refuses to drink water, then it can be replaced with rosehip decoction or cranberry juice.

• Pour raspberry tea for your child. It has an antipyretic effect.
• Wear light clothing. If there is a chill, cover with a thin blanket. You should change your baby's clothes in time if he is sweating.
• Turn down the batteries to make the air cooler. In this case, excess heat during inhalation will be spent on warming the air.
• Give your child medicine or use traditional methods.

Anti-fever medications for children

To bring down the temperature, doctors advise using suppositories, suspensions or tablets. The choice of drug depends on the age of the baby. The smallest children are prescribed candles. They are easy to use. From 3 one month old use Tsefekon or Efferalgan suppositories. For older children, it is recommended to use suspensions. They have a sweet taste. The most effective are Ibufen, Panadol, Paracetamol and Efferalgan. Before purchasing at the pharmacy, be sure to tell the baby’s age.

It should be remembered that until a child reaches 12 years of age, the use of acetylsalicylic acid. When used before this age, the development of Reye's syndrome may be provoked. This causes damage to the liver and brain.

Antipyretics are given 2-3 times a day and no more than 3 days in a row. Before taking the medicine, you should read the instructions. Familiarize yourself with the composition and side effects. You cannot use several drugs at the same time.

With the development of fever with spasm skin vessels(pale, cold hands and feet, marbling of the skin) after taking an antipyretic, you need to rub the skin until it turns red and urgently call a doctor.

Reduce a child's temperature using folk remedies

When the effect of the antipyretic has not yet begun, other methods should be used to reduce the fever. In this case, rubbing helps a lot. It should be remembered that rubdowns are contraindicated for children under one year of age.

When using vodka, it is diluted with water in a 1:1 ratio. Wipe the child’s skin with a cloth soaked in the solution. Particular attention should be paid to the armpits, feet, palms and back of the knees.

Rubbing with vinegar also helps reduce your baby's fever. Water with vinegar should have a slightly sour taste. Should not be used vinegar essence to prepare the solution.

With pale skin and cold extremities, rubbing will only worsen the situation.

A last resort at very high temperatures is to use a lytic mixture. In this case, an injection is given intramuscularly. The mixture contains “Analgin”, “Diphenhydramine” and “Papaverine” in proportions 1:1:1.

A cleansing enema of 1 teaspoon of soda diluted in a glass of water can reduce intoxication at high temperatures: six-month-old infants are given up to 50 ml of soda solution, after six months to one and a half years - up to 100 ml, after 2 years - up to 200 ml.

Under no circumstances should you use steam inhalations, hot compresses. This will only make the temperature rise.

If the temperature does not go down in any way, immediately call an ambulance.

About ways to measure body temperature

It would seem that there is nothing complicated in measuring body temperature. If you don’t have a thermometer at hand, you can touch the sick person’s forehead with your lips, but errors often occur here; this method will not allow you to accurately determine the temperature.

Another more accurate technique is pulse counting. An increase in temperature of 1 degree leads to an increase in heart rate of 10 beats per minute. Thus, you can approximately calculate how much the temperature has increased, knowing the indicator of your normal pulse. An increase in frequency also indicates fever. breathing movements. Normally, children take approximately 25 breaths per minute, and adults take up to 15 breaths.

Measuring body temperature with a thermometer is carried out not only in the armpit, but also orally or rectally (holding the thermometer in the mouth or anus). For young children, a thermometer is sometimes placed in the groin fold. There are a number of rules that should be followed when measuring temperature to avoid getting a false result.

• The skin at the measurement site should be dry.
• During the measurement, you cannot make any movements, it is advisable not to talk.
• When measuring the temperature in the armpit, the thermometer should be held for about 3 minutes (the norm is 36.2 - 37.0 degrees).
• If you use the oral method, then the thermometer should be held for 1.5 minutes ( normal indicator 36.6 – 37.2 degrees).
• When measuring the temperature in the anus, it is enough to hold the thermometer for one minute (the norm with this method is 36.8 - 37.6 degrees)

Normal and pathological: when is it time to “bring down” the temperature?

It is generally accepted that the normal body temperature is 36.6 degrees, however, as you can see, this is quite relative. The temperature can reach 37.0 degrees and is considered normal; it usually rises to such levels in the evening or in the hot season, after motor activity. Therefore, if before going to bed you saw the number 37.0 on the thermometer, then there is nothing to worry about yet. When the temperature exceeds this limit, we can already talk about fever. It is also characterized by a feeling of heat or chills, redness of the skin.

When should you lower your temperature?

Doctors at our clinic recommend using antipyretics when the body temperature in children reaches 38.5 degrees, and in adults – 39.0 degrees. But even in these cases, you should not take a large dose of an antipyretic; it is enough to reduce the temperature by 1.0 - 1.5 degrees so that the effective fight against infection continues without a threat to the body.

A dangerous sign of fever is the paleness of the skin, its “marbling”, while the skin remains cold to the touch. This indicates a spasm peripheral vessels. This phenomenon is usually more common in children and is followed by seizures. In such cases, it is necessary to urgently call an ambulance.

Infectious fever

For bacterial or viral infections The temperature almost always rises. How much it increases depends, firstly, on the amount of the pathogen, and secondly, on the state of the person’s body. For example, in older people, even an acute infection may be accompanied by a slight increase in temperature.

It is curious that with various infectious diseases, body temperature can behave differently: rise in the morning and fall in the evening, increase by a certain number of degrees and decrease after a few days. Depending on this, we allocated Various types fevers – perverted, relapsing and others. For doctors, this is a very valuable diagnostic criterion, since the type of fever makes it possible to narrow down the range of suspected diseases. Therefore, during infection, the temperature should be measured in the morning and evening, preferably during the day.

What infections increase the temperature?

Usually when acute infection there is a sharp temperature jump, and there are general signs intoxication: weakness, dizziness or nausea.

1. If the fever is accompanied by a cough, sore throat or chest, difficulty breathing, or hoarseness, then we are talking about a respiratory infectious disease.
2. If the body temperature rises, and along with it diarrhea begins, nausea or vomiting, and abdominal pain occur, then there is virtually no doubt that this is an intestinal infection.
3. A third option is also possible, when, against the background of fever, a sore throat, redness of the pharyngeal mucosa occurs, sometimes a cough and runny nose are noted, as well as abdominal pain and diarrhea. In this case, one should suspect rotavirus infection or the so-called “stomach flu”. But for any symptoms, it is better to seek help from our doctors.
4. Sometimes a local infection in an area of ​​the body can cause a fever. For example, fever is often accompanied by carbuncles, abscesses or cellulitis. It also occurs with (, kidney carbuncle). Only in the case of acute fever almost never occurs, because the absorption capacity of the mucous membrane Bladder is minimal, and substances that cause an increase in temperature practically do not penetrate into the blood.

Sluggish chronic infectious processes in the body can also cause fever, especially during an exacerbation. However, a slight increase in temperature is often observed in usual time when there are practically no other obvious symptoms of the disease.

When does the temperature still rise?

1. An unexplained increase in body temperature is noted when oncological diseases. This usually becomes one of the first symptoms, along with weakness, apathy, loss of appetite, sudden weight loss and depressive mood. In such cases, the elevated temperature persists for a long time, but remains febrile, that is, does not exceed 38.5 degrees. As a rule, with tumors the fever is wavy. Body temperature slowly increases, and upon reaching its peak, it also slowly decreases. Then there comes a period when the temperature remains normal, and then it begins to rise again.
2. At lymphogranulomatosis or Hodgkin's disease Undulating fever is also common, although other types may occur. Temperature rise in in this case accompanied by chills, and when it decreases, heavy sweat occurs. Increased sweating is usually observed at night. Along with this, Hodgkin's disease manifests itself as enlarged lymph nodes, and sometimes there is skin itching.
3. Body temperature rises when acute leukemia . It is often confused with a sore throat, since there is pain when swallowing, a feeling of palpitations, and increased The lymph nodes, often there is increased bleeding (bruises appear on the skin). But even before the appearance of these symptoms, patients note a sharp and unmotivated weakness. It is noteworthy that antibacterial therapy does not give positive results, that is, the temperature does not decrease.
4. Fever may also indicate endocrine diseases . For example, it almost always appears with thyrotoxicosis. In this case, the body temperature usually remains subfebrile, that is, it does not rise above 37.5 degrees, although during periods of exacerbations (crises) a significant excess of this limit can be observed. In addition to fever, thyrotoxicosis is associated with mood swings, tearfulness, increased excitability, insomnia, sudden loss of body weight due to increased appetite, trembling of the tip of the tongue and fingers, and menstrual irregularities in women. With hyperfunction of the parathyroid glands, the temperature can increase to 38 - 39 degrees. In the case of hyperparathyroidism, patients complain of severe thirst, frequent urge to urinate, nausea, drowsiness, and itchy skin.
5. Particular attention should be paid to fever that appears several weeks after respiratory illnesses (most often after a sore throat), since it may indicate the development of rheumatic myocarditis. Usually the body temperature rises slightly - up to 37.0 - 37.5 degrees, however, such a fever is a very serious reason to contact our doctor. In addition, body temperature may increase when endocarditis or, but in this case, the main attention is not paid to the pain in the chest, which cannot be relieved with available analgesics.
6. Interestingly, the temperature often rises when stomach ulcer or duodenum , although it also does not exceed 37.5 degrees. The fever gets worse if it occurs internal bleeding. Its symptoms are sharp dagger pains, vomiting " coffee grounds"or tarry feces, as well as sudden and increasing weakness.
7. Cerebral disorders (, traumatic brain injuries or brain tumors) provoke an increase in temperature, irritating the center of its regulation in the brain. Fever can be very different.
8. Drug fever most often occurs in response to the use of antibiotics and some other drugs, while it is part of allergic reaction, therefore it is usually accompanied by itchy skin and rashes.

What to do at elevated temperatures?

Many, having discovered that they have an elevated temperature, immediately try to reduce it, using antipyretic drugs available to everyone. However, their thoughtless use can cause even more harm than the fever itself, because elevated temperature is not a disease, but just a symptom, so suppressing it without identifying the cause is not always correct.

Especially it concerns infectious diseases, when infectious agents must die under conditions of elevated temperature. If you try to lower the temperature, the infectious agents will remain alive and unharmed in the body.

Therefore, do not rush to run for pills, but lower your temperature wisely when the need arises, our specialists will help you with this. If fever has been bothering you for a long time, you should contact one of our doctors: as you can see, it can indicate many non-communicable diseases, so without additional research not enough.
