After an acute respiratory viral infection, the temperature is kept for a week

Why does the temperature stay at 37.2-37.5: the reasons for the low-grade temperature

? Subfebrile is a rise in temperature from 37 to 37.9 degrees Celsius. Body temperature above 38 degrees is usually accompanied by very specific symptoms that any physician can tie to a particular disease. But the long subfebrile condition often remains the only sign that causes the patient to visit many experts and take many tests.

Why does the body need a low-grade fever?

Human being is a warm-blooded being, so we are able to maintain a more or less stable body temperature throughout life. Oscillations within 1 degree may occur with stress, after eating, during sleep, and also depending on the woman's menstrual cycle. At influence of some factors the defensive reaction of an organism - a fever can arise. Even subfebrile temperature figures allow to accelerate metabolism and make it impossible to multiply many harmful microbes. In addition, the temperature rise can speak of bodily or psychological ill health.

Normal human body temperature

The average temperature measured in the armpit is 36.6 degrees Celsius. But for different people this value can be individual. Someone's thermometer rarely shows a value greater than 36.2, and someone constantly lives with figures of 37-37.2 degrees. However, in most cases, subfebrile temperature indicates a slow inflammatory process in the body, so you should find out the cause of subfibrillity and find the focus of inflammation.

The upper limit of the human temperature norm of 37.0, all that is higher, can be considered as a slow inflammatory process and requires careful diagnosis. In a child under one year, the temperature 37.0-37.3 is normal because of the unsteady thermoregulation system.

However, it should be taken into account in what state the measurement takes place. If, for example, to measure the temperature of a person who is overheated in the sun or dressed in a woolen sweater, or if the patient has hyperthyroidism, a violation of thermoregulation - this should be taken into account.

How correctly to measure temperature?

There are several parts of the body where the temperature is usually measured. The most frequent are the rectum and axillary cavities. In the rectum, the temperature is usually taken for children, such data are more accurate, although some babies actively resist this procedure. And the subfebrile condition in infants is not at all an excuse to torment the child with rectal measurements. The classical version of thermometry in adults is in the armpit.

Temperature norms:

• axillary basin: 34,7C - 37,0C
• rectum: 36,6C - 38,0C
• in the oral cavity: 35,5C - 37,5C

Causes of subfebrile condition

Infectious causes Common viral and bacterial acuteinfections Chronic inflammatory foci( in the oral cavity, digestive organs, urogenital) Tuberculosis( both pulmonary and extrapulmonary forms) HIV Viral hepatitis	Autoimmune diseases Crohn's disease ulcerative ulcerative colitist ankylosing spondylitis rheumatism
non-infectious causes tumors( see. tests for oncology) Thyroid and other endocrine organs Diseases of the blood( anemia)	«tail" after a viral infection psychogenic causes Drug subfebrilitet

Infectious causes

The most frequent cause for subfebrile temperature is infection. So, most banal ARVI is accompanied by malaise, headache and joint pain, runny nose, cough and subfebrile condition. Some children's infections( rubella, chicken pox) are not very heavy, with low temperatures. In all these cases, there are bright signs of the disease.

With prolonged existence of the focus of inflammation all the symptoms are erased or become habitual. Therefore, the only sign of trouble remains a long subfebrile condition. In such cases, finding the source of infection is not easy.

Foci of infection, most often causing a prolonged temperature rise:

• ENT diseases - tonsillitis, sinusitis, otitis, pharyngitis, etc.
• Dental - carious teeth
• Diseases of the gastrointestinal tract - gastritis, colitis( inflammation of the intestine), pancreatitis, cholecystitis, etc.
• Inflammation of the urinary tract - pyelonephritis, urethritis, cystitis, etc.
• Inflammatory diseases of female and male genital organs - inflammation of the appendages, prostatitis.
• Abscesses in pricked areas
• Non-healing ulcers in elderly and diabetic patients

The doctor will appoint

• for general infection of blood and urine. Deviations in some indicators may indicate an inflammatory process in the body. For example, a change in the leukocyte formula and an increase in ESR.
• Inspection by narrow specialists: ENT doctor, gastroenterologist, surgeon, dentist, gynecologist
• Additional methods: CT, X-ray, ultrasound for suspected inflammation in a particular organ.

If the source of inflammation is found, it will take some time to heal, as chronic infections are worse given to therapy.

Rarely diagnosed infections

Toxoplasmosis

Very common infection, but clinical manifestations are rare( see symptoms of toxoplasmosis in humans).Almost all lovers of cats are infected with it. In addition, you can get infected with poorly-roasted meat.

Only toxoplasmosis in pregnancy( due to the risk of pathology in the fetus) and HIV-infected( due to the severity of the course) is clinically significant. In a healthy person, toxoplasmosis is present as a carrier, sometimes causing subfebrile temperature and eye damage.

Treatment does not require treatment( except for severe cases).Diagnose it with the help of ELISA( definition of antibodies), which is especially important when planning pregnancy.

Brucellosis

This is a disease that is often overlooked in the search for the causes of subfebrile. It is mainly found in farmers and veterinarians in contact with farm animals( see brucellosis in humans).Signs of the disease are manifold:

• fever
• articular, muscle and headache
• hearing and vision reduction
• confusion

This disease is not life threatening, but can lead to a persistent change in the psyche and the motor sphere. For diagnosis, PCR is used, which determines the source of the disease in the blood with high accuracy. Brucellosis is treated with antibiotics.

Parasitic infections

When infected with helminths in the organs, a flaccid inflammatory process may last for a long time. And often subfebrile condition is the only symptom of helminthic invasion( see signs of worms in humans).Therefore, with prolonged fever, especially combined with weight loss and digestive disorders, it is possible to pass tests:

• General blood test for eosinophils - cells that grow with an allergic reaction to helminths
• ESR - a sign of inflammation in the body
• analysis of feces for eggs worm( the most common in a particularregion, see pinworms in a child, symptoms of ascaridosis)

Treatment of helminthic invasion is performed by special drugs( see pills from worms).Sometimes it is enough to have one reception for a full recovery.

Tuberculosis

There is an erroneous opinion that tuberculosis is a disease of the past, it is now found only in prisons and only antisocial persons are ill. In fact, the number of TB patients does not decrease, but even increases. Everyone is at risk of getting sick, especially small children, medical workers, students in dormitories, soldiers in barracks. In general, the tubercle bacillus likes places with a large accumulation of people permanently living under the same roof.

Risk Factors:

• inadequate and unbalanced diet
• chronic pulmonary diseases
• diabetes
• residing with a human tuberculosis source
• tuberculosis in the past

Tuberculosis is a bacterial infection that affects mainly the lungs. In this case, the annual Mantoux test in children and fluorography in adults allows you to suspect and cure the disease on time.

If other organs are involved in the process, it is extremely difficult to find the cause of malaise with a "pure" X-ray of the lungs, since the tubercular lesion of the internal organs is perfectly masked for non-specific inflammatory processes. Until now, the diagnosis of extrapulmonary forms is extremely difficult and also when the diagnosis is differentiated, it is often "forgotten" about this infection.

Signs of tuberculosis:

General: high fatigability, working capacity decrease subfebrilitet evening excessive sweating and insomnia at night decreased appetite weight loss( up to exhaustion)	Urinary system: high pressure pain blood in the urine
Pulmonary forms: cough hemoptysis shortness of breath, chest pain	Genital tuberculosis: persistent primary infertility menstrual disorder postpartum acute inflammation of the female genital organs salpingitis, prostatitis
Bone and joint forms: pain in the spine change of posture restricted movement painful, swollen joints	Skin and ocular forms: persistent skin rash small confluent skin nodules Inflammation of the eye

To identify the disease, you need to undergo a chest examination( fluorography), conduct tuberculin tests( Mantoux), Diaskintest;if necessary, computed tomography of internal organs, renal radiography, GAS of fallopian tubes, etc.

Diagnosis of tuberculosis:

Mantoux test - intradermal injection of a special protein from the destroyed shell of the bacterium( tuberculin).This protein can not cause the disease, but in response to it there is a skin reaction, according to which the test is evaluated. Probation Mantou most children spend 1 time per year.

• In children under 5 years of age, the reaction should be positive( papules from 5 to 15 mm).If the reaction is negative, it means that the child has a congenital immunity to the disease or has received a low-quality BCG vaccine( or not at all).With a papule more than 15 mm, an additional examination is necessary.
• If the reaction has sharply increased compared to the previous one( more than 6 mm in comparison with the previous one), then this is considered a bend. That is, the child was infected with mycobacterium tuberculosis. Such children are likely to get this infection. Therefore, after an additional examination, the child is prescribed preventive doses of anti-tuberculosis drugs.

Important to know:

• the place of an injection can be wetted, it does not affect the size of a papule.
• sweet and citrus fruits is possible - this does not affect the size of the papule, if the child does not suffer from a pronounced allergy to these products.
• Mantoux test is not capable of causing tuberculosis
• Diaskintest is a Mantoux-like test, but exhibits a greater percentage of accuracy. Reaction to intradermal administration is also checked after 72 hours. The results of the test are not affected by BCG vaccination. Therefore, the positive result of the test is almost 100% infection with mycobacterium tuberculosis and the development of the disease. However, when infected with a bovine type of mycobacterium( unboiled milk, contact with a sick cow, a cat, a dog, etc.), as well as a complication of BCG vaccination( extremely rare, but there are complications in the type of persistent or disseminated BCG infection, when the vaccine strain "is activated"In weakened children), Diaskintest remains negative, and does not give 100% exclusion of tuberculosis of bovine type or activation of BCG vaccination.

The treatment of tuberculosis is a long, hard-to-bear, but still vital. Without therapy, tuberculosis slowly disables the person and leads to death. In time, the BCG vaccine protects young children from severe lethal forms of the disease, but unfortunately, does not protect the disease from either children or adults with prolonged contact with the patient with an active form. Modern drugs can cure foci of infection, but in recent decades, the number of drug-resistant forms that are difficult to treat has been increasing.

HIV infection

The human immunodeficiency virus attacks the body's defense system, making it immune to any, even the slightest infection. Virus infection occurs in the following ways( see how is transmitted by HIV):

• with unprotected sexual intercourse
• when injecting contaminated syringes
• with blood transfusions
• when manipulating the dentist's office, cosmetologist
• from mother to fetus

Because a large number of viral particles are required for infection, it is impossible to get HIV infection from coughing, sneezing or touching a sick person.

Symptoms of HIV infection:

There are no subjective signs during the incubation period( 1-6 months from infection).
Complications in acute period:

• Subfebrile or high temperature
• Enlargement of lymph nodes
• Rash of various nature
• Headache, nausea and vomiting
• Pain in muscles and joints

A latent period without obvious symptoms, but with active reproduction of the virus in the blood. Can last up to 20 years.
AIDS-associated complex( diseases that often occur and are difficult to develop with AIDS):

• Candidiasis( thrush in the mouth)
• Leukoplakia in the mouth( change of mucous membrane)
• Herpes with multiple relapses
• Pneumocystis pneumonia( not amenable to standard antibiotics)
• Tuberculosis
• Subfebrile, weight loss
• Inflammation of the parotid glands
• Contagious mollusc
• Dysplasia and cervical cancer
• Kaposi's sarcoma
• Toxoplasmosis of the brain
• Other inflammationflax disease

HIV diagnosis:

• ELISA( enzyme-linked immunosorbent assay).This is the first stage of the survey, which is carried out at the request of many employers. With the above symptoms, this method alone is not enough. Most of the infected antibodies to the virus appear after 3 months, some have a positive result only after 6-9 months. Therefore, it is recommended to conduct a study twice: after 3 and 6 months from possible infection.
• PCR( polymerase chain reaction).Very effective method, which allows to detect virus particles within 2 weeks after infection.
• methods for determining viral load and immune suppression. Additional methods used with a confirmed diagnosis.

With the final diagnosis of HIV infection, antiretroviral treatment should be initiated. It will allow to delay the emergence of AIDS as much as possible, to alleviate the already existing symptoms and significantly prolong the life of the patient.

Viral hepatitis B and C

One of the causes of intoxication and, as a consequence, subfebrile temperature, are hepatitis of a viral nature. These diseases begin in different ways: some are acutely, with pain in the hypochondrium, jaundice, high fever. Some people practically do not feel the onset of the disease( see hepatitis C how many live with it)

Signs of slow viral hepatitis:

• malaise, weakness
• subfebrile, sweating
• discomfort in the area of ​​the liver after eating
• slight, almost invisible jaundice( see symptoms of jaundice)
• joint and muscle pain

Since a large percentage of viral hepatitis passes into a chronic form, the subfebrile condition may return with each exacerbation.

Transmission routes of viral hepatitis:

• Sexual contacts
• Medical instruments
• Blood transfusion
• Instruments in manicure and dental offices
• Needle syringes
• from mother to fetus

Diagnosis of viral hepatitis:

• PCR method with high accuracy, detects particles of viruses in the blood
• ELISA- a method that allows to detect antibodies to various components of the virus. With it, you can determine the carrier, the active form of the disease, the risks of infection of the fetus. It is also possible to distinguish between acute and chronic hepatitis.

Treatment of acute hepatitis of viral origin is not performed. Concomitant complications are usually treated. Treatment of chronic hepatitis during the exacerbation is carried out by antiviral special drugs, hepatoprotectors, cholagogue. Chronic process in the liver can lead to cirrhosis and cancer, so all patients with hepatitis should be examined regularly by a specialist.

Tumors

With the development of a malignant tumor in the body, all organ systems begin to work differently. The metabolism also changes. As a result, there are paraneoplastic syndromes, including subfebrile. Suspect the tumor can be after eliminating more obvious causes( infection, anemia).Malignant neoplasm during disintegration throws out pyrogens into the blood - substances that raise the temperature. Often, on the background of a tumor, infections become worse, which also causes fever.

Features of paraneoplastic syndromes:

• poorly amenable to standard for this indication of therapy
• often recurs
• decreases with treatment of underlying disease( tumor)

Frequent paraneoplastic syndromes:

Fever poorly treatable by antipyretic and anti-inflammatory agents.
Skin manifestations:

• Black acanthosis( for cancer of the digestive, breast and ovarian organs)
• Erythema Darya( for stomach cancer and breast cancer)
• Skin itching without rash and obvious causes

Endocrine signs:

• Cushing's syndrome( excess ACTH-hormone of the adrenal glands) - with lung cancer, pancreatic, thyroid or prostate cancer
• Gynecomastia( breast augmentation in men) - with lung cancer
• Hypoglycemia( low glucose) - with lung cancer, digestive organs

Changes in blood:

• Anemia( with tumors of different locations).By itself, anemia also leads to a long subfebrile condition.
• Increased ESR( over 30) for a long time

It should be noted that not all cancer patients have obvious paraneoplastic syndromes. And not all the above signs necessarily indicate a tumor. Therefore, when a subfebrile condition of unclear etiology, especially in combination with other paraneoplastic symptoms, requires a thorough examination.

Thyroid Diseases

With increased thyroid function( hyperthyroidism), all metabolic processes are dramatically accelerated. This immediately affects the body temperature. In patients with thyrotoxicosis, the thermometer rarely shows less than 37.2 degrees.

Symptoms of thyrotoxicosis:

• subfebrile condition
• irritability
• frequent pulse, high pressure
• liquid chair
• weight loss
• hair loss

For thyroidectosis diagnosis it is necessary to make an ultrasound of the thyroid gland and donate blood to hormones: T3, T4, TTG and antibodies to TSH.Based on the results of the tests, the doctor will prescribe the appropriate treatment.

Anemia - as an independent disease or a component of other diseases

Anemia - a decrease in the level of hemoglobin. This condition occurs for various reasons, ranging from chronic bleeding( with hemorrhoids, for example), ending with a violation of iron absorption( with diseases of the gastrointestinal tract).It is iron deficiency in most cases that causes this condition. Often anemia occurs in women with heavy menstruation and vegetarians who abandoned animal products.

Lower limits of the norm of hemoglobin:

• Men: 20 to 59 years: 137 g / l, from 60 years: 132 g / l
• Women: 122 g / l

In some cases, the hemoglobin level may be normal, but the iron content in the bloodsharply reduced. This condition is called latent iron deficiency.

Symptoms of anemia and latent iron deficiency:

• unmotivated subfebrile condition
• cold hands and feet
• loss of strength and reduced performance
• frequent headaches and dizziness
• bad hair and nails( see causes of hair loss)
• drowsiness during the day
• aversion to meat products andpropensity to eat inedible
• skin itching, dry skin
• stomatitis, glossitis( inflammation of the tongue)
• poor tolerance of stuffy rooms
• unstable stool, incontinence

The higher the above characteristics, the higher the probability of a lack of iron in the body. To confirm the diagnosis, the following tests are needed:

• Blood test for hemoglobin
• Ferritin level
• If necessary - digestive examination of

If iron deficiency is confirmed, then it is necessary to start treatment with ferrous iron preparations. This is Sorbifer, Tardiferon, Ferretab( see iron preparations for anemia).All iron preparations should be taken together with ascorbic acid, for at least 3-4 months.

Autoimmune diseases

In autoimmune diseases, the body begins to attack itself. Immunity is tuned against the cells of certain organs and tissues, causing chronic inflammation with periods of exacerbation. Against this background, the body temperature also changes.

The most common autoimmune diseases:

• Rheumatoid arthritis
• Thyroiditis Hashimoto( thyroid damage)
• Systemic lupus erythematosus
• Crohn disease( bowel disease)
• Diffuse toxic goiter
• Sjogren's syndrome

For the diagnosis of autoimmune conditions, the following tests are needed:

• Erythrocyte sedimentation rate( ESR) - an indicator whose increase indicates an inflammatory reaction
• C-reactive protein - a parameter in a biochemical blood test, speaks of inflammation
• Rheumatoid factor( increases with rheumatoid arthritis, vasculitis, other autoimmune processes)
• LE cells( for diagnosis of systemic lupus erythematosus)
• additional examination methods

With a proven diagnosis, it is necessary to begin treatment. It includes hormonal drugs, anti-inflammatory, immunosuppressants. Therapy allows you to control the disease and reduce the risk of exacerbations.

Residual effects after

disease

All people at least once in their lives suffer from acute respiratory viral infection, influenza-acute respiratory viral infection. Often the main symptoms do not stay longer than a week: cough, runny nose, fever and headache. And here a subfebrile condition can be saved some months after the transferred or carried illness or disease. It is not necessary to treat such a condition, it will pass by itself. You can strengthen your health with dosed physical exertion and outdoor exercise( see how to recover from the flu).

Psychogenic causes

Subfebrile is a manifestation of accelerated metabolism. It, as well as all processes in the body, is influenced by our psyche. Under stresses, experiences and neuroses, it is metabolic processes that are violated in the first place. Therefore, people with subtle emotional organization, especially in young women prone to hypochondria, often have unmotivated subfebrile fever. And the more active the temperature measurements, the worse a person feels. To diagnose this condition it is possible to pass tests to assess psychological stability:

• Questionnaire for detecting panic attacks
• Hospital scale of depression and anxiety
• Bek scale
• Individual-typological questionnaire
• Toronto alexithymic scale
• Scale of emotional excitability

Based on the results of these tests,need to consult a therapist( not forgetting to capture these results with you).Treatment of this condition can be reduced to sessions of psychotherapy and the use of antidepressants or tranquilizers, sedatives. Often, all unpleasant symptoms go away when a person realizes the baselessness of fears and ceases to measure temperature.

Drug subfebrile condition

Prolonged or active use of certain drugs may cause fever to subfebrile digits. These drugs include:

• epinephrine, ephedrine, noradrenaline
• atropine, some antidepressants, antihistamines and antiparkinson drugs
• antipsychotics
• antibiotics( penicillin, ampicillin, isoniazid, lincomycin)
• chemotherapy for tumors
• narcotic pain medications
• preparations of thyroxine( thyroid hormone)

Cancellation or replacement of therapy relieves of unpleasant subfebrile condition.

Subfebrile in children

The reasons for the subfebrile temperature in a child are exactly the same as in adults. But parents should remember that the temperature to 37.3 degrees in a child up to a year is considered normal and does not require antipyretics and the search for causes. Therefore, if the baby feels well, is active, cheerful and does not suffer from a lack of appetite, then it is not necessary to treat subfebrile condition. However, if the child is older than a year of long subfebrile condition, lack of appetite, weakness - the cause should be established.

How to find the cause of the subfebrile condition?

To exclude dangerous and even deadly variants, it is necessary to pass a survey with specialists.

Algorithm for examination at subfebrile temperature:

• Determination of the nature of the fever: infectious or noninfectious
• General blood analysis
• General urine analysis
• Analysis of feces for helminths
• Blood biochemistry: determination of c-reactive protein
• Chest X-ray( to exclude tuberculosis, endocarditis, cancerlungs)
• X-ray or CT of the nasal sinuses( to exclude sinusitis)
• ultrasound of the heart, digestive organs
• Bacteriological culture of urine( to exclude inflammation in the urinary systeme)
• Tuberculin samples, dyskintest( to exclude tuberculosis)

Optional:

• With additional methods to exclude HIV, brucellosis, viral hepatitis, toxoplasmosis
• Consultation of phthisiatrician for unspecified tuberculin tests, night sweats, weight loss
• Consultation of oncologist and hematologisttumors and blood diseases)
• Consultation of rheumatologist
• Consultation of psychotherapist

Temperature without signs of cold is a serious cause for concern

"I have a temperature", - we say, when the column of the thermometer rises above the mark of + 37 ° С. .. And we say incorrectly, because the indicator of the thermal state our body has always. And the said common phrase is pronounced when this indicator exceeds the norm.

By the way, the body temperature of a person in a healthy state can vary within a day - from + 35.5 ° С to + 37.4 ° С.In addition, the norm at + 36.5 ° C is obtained only when measuring the temperature of the body in the armpit, if you measure the temperature in your mouth, then on the scale you will see + 37 ° C, and if the measurement is carried out in the ear or rectally, thenall + 37.5 ° C.So, the temperature of + 37,2 ° C without signs of a cold, and even more so the temperature + 37 ° C without symptoms of a cold of particular concern, as a rule, do not cause.

However, any increase in body temperature, including temperature without signs of a cold, is the response defense response of the human body to an infection that can lead to a particular disease. Therefore, doctors say that the increase in temperature indicators up to + 38 ° C indicates that the body came into conflict with the infection and began to develop protective antibodies, immune system cells, phagocytes and interferon.

If the fever without colds lasts long enough, then the person feels bad: the load on the heart and lungs increases significantly, as energy consumption and the need for tissues in oxygen and nutrition increase. And in this case only the doctor will help.

Causes of fever without symptoms of cold

A fever or fever is observed in almost all acute infectious diseases, as well as during the exacerbation of certain chronic diseases. And in the absence of catarrhal symptoms, doctors can determine the cause of high body temperature indices by isolating the pathogen either directly from the local focus of the infection or from the blood.

It is much more difficult to determine the cause of temperature without signs of a cold, if the disease has arisen due to exposure to the organism of opportunistic microbes( bacteria, fungi, mycoplasma) - against the background of a decrease in general or local immunity. Then it is necessary to conduct a detailed laboratory study of not only blood, but also urine, bile, sputum and mucus.

In clinical practice, cases of persistent - for three or more weeks - a fever without signs of a cold or any other symptoms( with scores above + 38 ° C) are called fever of unknown origin.

To the most "simple" case of a temperature of 39 ° C without signs of a cold( in the sense of diagnosis, of course) is the appearance of her after a trip to hot foreign lands( especially in Africa and Asia) where he was bitten by a mosquito infected with parasites of the species Plasmodium. That is, in addition to souvenirs from the journey a person brings malaria. The first sign of this dangerous disease is fever, which is accompanied by headache, chills and vomiting. According to WHO, every year around the world, malaria from 350 million to 500 million people.

Causes of fever without cold symptoms can be associated with such diseases as:

• inflammatory diseases of bacterial origin: endocarditis, pyelonephritis, osteomyelitis, pneumonia, tonsillitis, andexitis, sinusitis, meningitis, prostatitis, inflammation of the uterine appendages, sepsis;
• infectious diseases: tuberculosis, typhus and recurrent typhoid, brucellosis, Lyme disease, HIV infection;
• diseases of viral, parasitic or fungal etiology: malaria, infectious mononucleosis, candidiasis, toxoplasmosis, syphilis;
• oncological diseases: leukemia, lymphoma, tumors of the lungs or bronchi, kidneys, liver, stomach( with and without metastases);
• systemic inflammation, including autoimmune nature: polyarthritis, rheumatoid arthritis, rheumatism, rheumatoid arthritis, rheumatic polymyalgia, allergic vasculitis, nodular periarthritis, systemic lupus erythematosus, Crohn's disease;
• endocrine diseases: thyrotoxicosis.

The increase in temperature indicators can be caused by changes in the hormonal sphere. For example, during a normal menstrual cycle, women often have a temperature of + 37-37.2 ° C without signs of a cold. In addition, unexpected sudden temperature increases are reported by women with early menopause.

Temperature without signs of cold, so-called subfebrile fever, often accompanies anemia - a low level of hemoglobin in the blood. Emotional stress, that is, the release of a high volume of adrenaline into the blood, is also capable of raising body temperature and causing adrenaline hyperthermia.

As experts note, a sudden jump in temperature can be caused by taking medications, including antibiotics, sulfonamides, barbiturates, anesthetics, stimulants, antidepressants, salicylates, and some diuretics.

In fairly rare cases, the causes of temperature without signs of colds lie in the diseases of the hypothalamus itself.

Temperature without cold symptoms: fever or hyperthermia?

The regulation of human body temperature( body thermoregulation) occurs at the reflex level, and the hypothalamus, which belongs to the parts of the intermediate brain, is responsible for it. The function of the hypothalamus also includes the control of the work of our entire endocrine and autonomic nervous system, and it is in it that there are centers regulating body temperature, hunger and thirst, a cycle of sleep and wakefulness, and many other important physiological and psychosomatic processes.

In the rise in body temperature involved special protein substances - pyrogens. They are primary( exogenous, that is, external - in the form of toxins of bacteria and microbes) and secondary( endogenous, that is, internal, produced by the body itself).When a disease occurs, the primary pyrogens force the cells of our body to produce secondary pyrogen, which transmits the impulses to the thermoreceptors of the hypothalamus. And the latter, in turn, begins to correct the body's temperature homeostasis in order to mobilize its protective functions. And while the hypothalamus does not adjust the disturbed balance between heat formation( which rises) and heat emission( which decreases), a person suffers from fever.

The temperature without signs of cold also happens with hyperthermia, when the hypothalamus does not participate in its increase: it simply did not receive a signal to start protecting the body from infection. This increase in temperature is due to a violation of the heat transfer process, for example, with significant physical exertion or due to the general overheating of the person in hot weather( which we call heat stroke).

Treatment of temperature without signs of cold

So, we remind that treatment of temperature without signs of cold should begin with finding out the true reason of this problem. And for this you should turn to the doctors - and not a bag.

Only a qualified doctor( and, often, not one) will be able to answer the question, where did you get a high fever without signs of a cold, and prescribe a comprehensive treatment.

If the detected disease appears to be infectious-inflammatory, antibiotics will be prescribed. And, for example, with lesions of fungal etiology prescribe polyene antibiotics, drugs of the triazole group and a number of other medication medications.

In general, as you understand, for the treatment of arthritis you need some drugs, for the treatment of thyrotoxicosis or, say, syphilis - quite different. With an increase in temperature without signs of a cold, when this single symptom combined so different diseases, only a qualified doctor can determine which medicines should be taken in each specific case. So, detoxification, that is, to reduce the level of toxins in the blood, resort to intravenous drip injection of special solutions, but exclusively in the clinic.

Therefore, curing a fever without signs of a cold is not just a fever-reducing pill like paracetamol or aspirin. Any doctor will tell you that with the diagnosis not yet established, the use of antipyretic drugs can not only prevent the identification of the cause of the disease, but also aggravate its course. So the temperature without signs of a cold is really a serious cause for concern.

Temperature 37 lasts a week - causes

On the thermometer 37-37,5?Do not panic or get upset! Such indicators on the thermometer may indicate fatigue, stress and severe physical fatigue. But what if the temperature of 37-38 lasts a week? Does this really mean serious health problems?

Temperature 37 as a norm

The temperature within 38 degrees, which is held for a week, is called subfebrile. It can be a norm option:

• after severe physical exertion;
• in the second phase of the menstrual cycle;
• during the menopause;
• during pregnancy.

Also, the temperature 37 can not fall off a week in a woman during lactation. Especially high rates are in the first days of the flow of milk. But if, at the same time, there is pain in the chest, it can be a symptom of purulent mastitis.

Pathological causes of temperature

Often the temperature of 37-37.5 lasts a week if there is a serious pathology in the body. For example, such indicators on the thermometer may appear with:

• intestinal infections;
• toxoplasmosis or helminthic invasions;
• tuberculosis;
• ulcerative colitis;
• systemic lupus erythematosus;
• is rheumatoid arthritis.

The reason for the fact that the temperature 37 lasts for a week, are allergic and surgical pathologies. Such indicators on the thermometer can last quite a long time for diseases of blood vessels and heart, problems with the nervous system, chronic lung pathology. Accompounding subfebrile fever immunodeficiency states and cancer.

Do you have a usual SARS?Why does the temperature last for a week? With a mild infection of respiratory organs, such indicators on the thermometer do not indicate complications. But if this condition is accompanied by an aching in the muscles, a strong runny nose or an increase in lymph nodes, it is better to consult a doctor.

The temperature of 37-37.5 can occur during the week for urinary tract infections. This is especially typical for inflammation of the bladder. Also, such indicators can often be observed for a long time with cystitis, kidney disease and gastrointestinal disease. When women have a temperature of 37-37.5 and have a lower abdominal pain, it is most likely a symptom of infectious diseases of the genitals. This condition is accompanied by various parasitic diseases.

Subfebrile fever may be noted in pathologies of organ systems. For example, this phenomenon is very often observed in the syndrome of autonomic dystonia, Addison's disease or hypertension. In pathologies affecting organ systems, a slight increase in temperature can be combined with increased pressure, headaches, loss of appetite or weakness.

What should I do at a temperature of 37?

If you have a week of 37-37.5, do not use medication to reduce it. They should be used only:

• on late pregnancy;
• for severe heart or lung disease;
• in diseases of the nervous system.

What does it mean if the temperature 37 lasted a month? Temperature 37 - what to do?

Feel drowsiness, loss of strength and apathy? All this can serve as symptoms of fever. So, the thermometer confirmed your fears. The temperature does not fall below 37 degrees a long time - a week, two, a month. .. What should I do? No, of course, the situation is not critical, there is no acute threat to life and there is no need to call the resuscitation team either. However, it is strictly necessary to find out the cause.

Why does the temperature rise?

The raised temperature of the person is a protective reaction of our organism. It is caused by pyrogens. These are special substances that, on the one hand, can serve as the products of vital activity of a number of pathogens, on the other hand, they can be produced by our immune cells. In simple terms, the temperature is the weapon with which our body is fighting viruses. At 38 ° C, it produces interferon. It is he who serves as a threat to pathogens.

As a rule, with such symptoms, the patient is prescribed antibiotics, as well as drugs for lowering the temperature. The latter is disastrous not only for viruses, but also for our body, giving a strong strain on the heart and lungs. It is quite another matter - the body temperature is 37 degrees, which doctors call subfebrile. It can last for a long time, and it is not easy to find out its cause even to experienced therapists after a thorough medical examination. What does the temperature mean 37 degrees?

Not a reason for panic

Reason number one is the absence of any reasons, forgive the tautology! School textbooks on anatomy and medical encyclopedias have rooted in our minds the fact that the normal human temperature is exactly 36.6 degrees. Anything less than this value is an indicator of the decline of strength, and all that is greater is a symptom of an infection or an inflammatory process. But does this always correspond to reality?

It turns out that the temperature norm for each individual and can vary within 35.5-37.5 degrees. This vital indicator is influenced by a number of factors - gender and age, level of physical activity, hormonal background. In some cases, it may depend on the temperature and humidity of the air, as well as the time of day. Between five and eleven o'clock in the evening its value can go up by 0.5 degrees. In children, in some cases, the normal temperature can reach 37.5 degrees. Sometimes it rises in women in menstrual and climacteric period. However, the temperature of 37 in an adult is not an alarm signal only when no other symptoms are observed. Otherwise, it is worth immediately contacting the therapist to avoid serious consequences.

Cold is the main suspect

If you have a prolonged temperature of 37, the cause is primarily to look for in colds. As a rule, it is accompanied by other symptoms - headache, body aches, runny nose, a sore throat and a beginning dry cough. Subfebrile temperature can persist even after the transfer of acute viral diseases. The body needs some time to regain strength and restore the basic indicators to normal.

Complications of cold and viral diseases

However, cold and viral diseases due to our negligence, on the one hand, and the resistance of modern strains of viruses to antibiotics, on the other, can go on to chronic tonsillitis and have other complications. Inflammatory processes in the tonsils( both pharyngeal and palatine) can also cause a temperature of 37. To avoid such negative consequences, cold and viral diseases must be treated until all the symptoms disappear and the temperature is restored.

Is it a cold?

"Temperature 37, sick with a cold", - such reports are not uncommon on thematic forums. However, you are sure that this is a cold disease, and not, say, focal pneumonia? We often err, believing that the main symptom of pneumonia is high fever. It is a myth. The thermometer shows 37 degrees. Temperature is not critical, but requires your attention. If she is accompanied by a cough and general weakness, it is better to be safe and make an X-ray. With this disease in the lung tissue inflammatory processes occur. Often they are caused not by infections, however, against their background, fungal or viral-bacterial pneumonia may well develop. This disease requires immediate treatment with antibiotics. Remember that late diagnosis worsens the prognosis. Despite the presence of various types of strongest antibiotics, in cases of neglected form of pneumonia, a lethal outcome is possible.

Caution: Tuberculosis!

Weakness, temperature 37 and other symptoms listed above can also be caused by bacterial, fungal, viral or parasitic infections. Sometimes they point to toxoplasmosis, syphilis, immunodeficiency virus and tuberculosis. The latter requires special attention.

If in the last century tuberculosis was considered a disease of the poor, then today, unfortunately, no one is insured against it. The causative agent of this disease is mycobacterium tuberculosis. According to WHO, every third inhabitant of the Earth is its carrier. However, it is infected - it does not mean that it is sick. In the first case, microbacteria are not active in the human body. Such people do not experience symptoms of the disease and can not infect others. However, in case of weakening of immunity, resulting in stress, inadequate nutrition, excessive physical activity and lack of sleep, microbacteria can affect the lungs, and in some cases, other organs and systems.

The number of tuberculosis patients today is only 1% of the population according to official data. In reality, this figure is several times higher. Every day, without knowing it, we often face sick tuberculosis. Representatives of various strata of society are subject to this disease. Doctors and pharmacists, public transport drivers and sellers, teachers in kindergartens and university teachers. This disease does not choose. However, with healthy immunity, only a patient with an open form of tuberculosis can be infected. In this case, microbacteria enter the environment with saliva and sputum.

Fluorography is necessary to detect tuberculosis. In many clinical cases, the temperature was 37 months, after which the patient was diagnosed with the disease. Easy coughing for a long time - another reason to show your doctor. However, tuberculosis is not a verdict. In the vast majority of cases, this ailment can be overcome if the treatment scheme is followed. To prevent tuberculosis, vaccination is being performed today.

Stress as a cause of high temperature

"Temperature 37 lasted a month, and then recovered," - many of us faced this situation. We almost never associate a fever with stress. Today they have become so common for us that we simply do not react to them, which can not be said about our body. It reacts to external stimuli on the physical and chemical levels. When we are nervous, pressure builds up, heart rate increases, and adrenaline enters the bloodstream. All systems start to work more actively, as a result of which the temperature also rises. It turns out that this phenomenon is so widespread that specialists even introduced a special term for it - "psychogenic temperature".In this case, a person can also experience dizziness, shortness of breath and general malaise. Frequent stress can cause with time chronic fatigue syndrome. If you have a temperature of 37 months, then this can testify just about him. With such a disease, the functions of the nervous, endocrine and immune systems may be disrupted. A simple rest will not save you from such serious consequences. In this case, the help of a specialist is required.

The aggravation of the "chronicle"

The thermometer shows 37 degrees. The temperature can be caused by exacerbation of chronic diseases and inflammation in various organs. Dysfunction of the cardiovascular system and thyroid gland, peptic ulcer, gastritis, pyelonephritis, etc. For a long time, the main symptom of these diseases may be a low-grade fever. It can also be accompanied by pain in certain areas. In these cases, you need to contact a specialist. The temperature will return to normal when the inflammation passes.

Malignant neoplasms

A slight increase in temperature, especially in the evening, can be caused by malignant tumors. It leads to intoxication. A higher temperature( from 37.5 to 38 degrees) indicates that the body has begun the process of disintegration of the tumor, which was joined by inflammation. In many cases, oncology develops against the background of already existing chronic diseases. However, in some cases, malignant cells can affect healthy tissues and for a long time do not manifest themselves in any way. If the temperature of 37 lasted a month, and acute pain was not observed, unfortunately, this is not a reason to discard this version. It is not superfluous to undergo a general examination. The last one is shown annually. Diagnosis of the disease in the early stages is the key to the success of her treatment. One of the countries with the lowest rates of death from cancer today is Israel. The employment contract, which is signed by specialists when applying for a job, provides for dismissal in the event of failure to attend a medical examination once a year. Such a discipline would not hurt us.

"Interesting position"

The reason for raising the temperature to 37 degrees can not only not upset you, but also serve as an occasion for the greatest joy in life. In some cases, it is pregnancy. Sometimes subfebrile temperature accompanies all nine months, during which a woman carries a fetus. It can determine the physiological characteristics and individual response of the female body to pregnancy. However, be cautious: the increase in temperature in the "interesting position" can also be caused by viral infections and inflammatory processes. Self-medication is fraught with the most negative consequences. Consultation with a gynecologist is strictly required!

Temperature 37: what to do?

Above are possible causes of subfebrile temperature. But what if, in the absence of pain and other symptoms on your own, you can not even put an approximate diagnosis to contact a narrow specialist? So, instead of the usual cheerfulness, you feel the weakness and decay, and on the thermometer the temperature is 37. What should I do? It's time to move on to concrete actions. First of all, you need to consult a therapist and take a blood test. If the body has inflammation, then its results will show it.

What should I look for?

Can I read the analysis myself? Yes, and for this you will not need a medical education. On the received form with the result you will see your indicator and rate. The disease will indicate an increased number of leukocytes, as well as a deviation in the larger side of the rate of erythrocyte sedimentation. But hemoglobin, on the contrary, will be reduced. Such results can be caused by a variety of ailments. For more accurate data, it is necessary to undergo a fluorographic study, as well as ultrasound of the pelvic organs and abdominal cavity. This will eliminate or confirm a number of diseases, in particular, tuberculosis.

Most likely this is the effect of antibiotic treatment, because ARVI does not treat antibiotics, ARVI is treated with antiviral drugs, and the pediatrician shouldyl know. retake tests, the KLA and OAM, look for the cause of the temperature, because the temperature is not small.
