Subfebrile body temperature. What is it causes in women during pregnancy, children, men, how to measure, the rate in oncology, IRR, chronic tonsillitis, ankylosing spondylitis. Treatment

One of the symptoms, which often indicates the occurrence of health problems, is a low-grade body temperature. It's a state, the appearance of which in any case can not be ignored.

It can occur as a result of prolonged psychological stress, to testify about the development of a dangerous disease or pathological processes accompanied by a chronic nature.

How to properly measure the temperature

The traditional instrument for measuring body temperature - thermometer. It can be electronic or mercury. A more modern version - infrared (contactless) thermometers. There are several ways in which measured temperature.

End of the thermometer is placed:

• in the armpit;
• in his mouth;
• into the rectum;
• on the forehead;
• in the ear opening.

Two recent method involves the use of infrared devices.

Mercury thermometer is suitable for temperature measurement in the armpit and mouth, inserting it into the rectum is not recommended. For rectal method is suitable electronic thermometers. Also, they are convenient to use when measuring the temperature axillary and oral ways.

Axillary method, despite its prevalence and popularity, is considered the least accurate option. Often the temperature readings in the right armpit a little different from the figures in the left armpit.

During the temperature measurement in the armpit skin should be dry. Mercury end of the thermometer in the armpit a recess, a hand pressed to the body to the thermometer did not move. Duration: 7-9 minutes. A similar algorithm steps in the application of the electronic thermometer, but the measurement will take less time (about 1 min.) Typically, the completion signal indicates procedures.

But it is believed that some models of thermometers programmed temperature measurement in a straight line gut, so when using the armpit is not always necessary to remove the instrument immediately after signal. The duration of the measurement can be up to 4-5 minutes.

It is not always authentic and oral route. It is not suitable for small children, for people with diseases of the oral cavity and upper respiratory tract (when disturbed breathing), with mental disabilities. After eating or smoking temperatures, try to measure - readings may be inaccurate.

To measure temperature orally, the thermometer at the end of a tongue. Roth try to close tightly. Length measuring mercury thermometer for - 5 min; for e - to the audio signal. The most accurate reading will give rectal measurement. But it has its contraindications. These include hemorrhoids, proctitis, constipation and diarrhea.

End of the thermometer prior to insertion into the rectum is lubricated with oil. The measuring process takes place at a position lying on its side (for young children - pronation). The depth of introduction of - not more than 3 cm. A thermometer is introduced slowly without sudden movements. Control after the beep.

Infrared thermometer is convenient that at applying forehead almost immediately outputs the result. Ideal for temperature measurement in children. Before the procedure, make sure that the forehead dry. Otherwise, the skin rubbed with a cloth.

Another accurate way - in-ear measurement. Infrared instrument is introduced into the ear canal to a depth of 1 cm and a few seconds is obtained temperature values.

Typical normal temperature:

• 36,3 - 36,9 ° C (in the armpits, on the forehead);
• 37,3 - 37,7 ° C (in the ear and in the rectum);
• 36,8 - 37,3 ° C (in the mouth).

What is a low-grade body temperature?

Low-grade body temperature - it is a condition that often signals a fault in the body. Subfebrile temperature limits: 37 - 38 ° C. temperature jumps are different regularity, can last for weeks or even years.

The presence of this symptom is evidenced not only elevated temperature readings. State is accompanied by weakness, bad mood, headache. Often unpleasant signs are beginning to manifest themselves in the evening.

The following signs indicate the infectious nature subfebrile:

• temperature values ​​normalized after temporarily receiving antipyretics;
• temperature brings severe discomfort;
• temperature readings are changing throughout the day.

Noninfectious subfebrilitet different:

• immunity to antipyretic;
• constancy diurnal temperature values;
• without the occurrence of unpleasant symptoms expressed.

When a low-grade fever is considered normal during pregnancy, women, children and men?

Low-grade fever is not always indicative of the presence of abnormalities in the body. Sometimes this is normal and not cause for concern. For example, the temperature rise in women can occur during pregnancy (usually during the first trimester), in menopause, with the onset of menses, at least - in the period of lactation.

In very young children have not yet developed a normal thermoregulation, so the measurements can be seen higher temperature values. Also, do not need to sound the alarm if the temperature is held against the backdrop of teething.

Children in adolescence sometimes recorded temperature rises - they are associated with hormonal changes in the body.

Low-grade fever in men in the absence of serious pathologies observed much less frequently than women. If such cases occur, they can be attributed to nerves, chronic fatigue, hormonal disorders. Increasing the temperature characteristics is considered relatively safe, if caused by a stressful situation.

After removing the source of irritation and normalization of psychological state, the temperature ceases to rise to subfebrile marks. Also in men, women and children of low-grade fever may persist for several months after suffering an infectious disease.

Causes of abnormal rise in temperature to subfebrile marks

Subfebrile causes of many - the most common ones:

1. Infectious diseases.
2. Chronic diseases of internal organs.
3. Malignant tumors.
4. Viral diseases.
5. Autoimmune diseases.
6. Taking certain drugs.
7. Endocrine disorders.
8. Prolonged stress and fatigue.
9. Post-infectious period.
10. Allergic reactions.
11. Violation of metabolic processes.
12. Infestation.

Acute infectious diseases

Low-grade body temperature - it is a condition that occurs on a background of infectious diseases.

For common diseases include:

• caries and other inflammatory processes in the oral cavity;
• sinusitis;
• bronchitis;
• SARS;
• otitis;
• pneumonia;
• furunculosis;
• inflammation of the urogenital tract.

After the elimination of the disease, the temperature returns to normal values.

Chronic nonspecific infection

For chronic nonspecific infections, which may be accompanied by fever, include:

• respiratory diseases (bronchitis, bronchial asthma);
• gastrointestinal tract diseases (gastritis, cholecystitis, pancreatitis);
• problems of the genitourinary system (adnexitis, cystitis, urethritis, pyelonephritis).

toxoplasmosis

One of the signs of infection with Toxoplasma - subfebrile temperature. Especially dangerous is the disease for pregnant women - they have a weakened immune system, and the body is difficult on its own to defeat the disease. In people with healthy immune system, the infection takes place relatively quickly and without consequences.

Tuberculosis

Low-grade body temperature - it is a condition that has an effect in pulmonary tuberculosis. Generally, with an increase in the latent phase face (up to 37,5 ° C) or at a low intensity inflammation (up to 38 ° C). Often the temperature jumps - the only sign of the disease.

As a rule, the growth temperature values ​​occur in the evening and in the morning indices return to normal. TB infection can affect not only the lungs, but also the bones, organs of excretion, skin, eyes. Additional symptoms: weight loss and excessive sweating.

HIV infection

Sometimes the only low-grade fever may indicate the presence in the body of HIV. It can be called the first symptom. Later appear the other signs of infection: swollen lymph nodes, there are rashes, nausea, headaches and joint pain.

Malignant tumors (oncology)

As in the case of HIV infection, low-grade fever (with attendant state weakness) may be one of the first symptoms incipient malignant tumor. The problem is that the correct diagnosis at this early stage is difficult.

Viral hepatitis B and C.

In viral hepatitis B and C, the elevated temperature is shown together with:

• muscle and joint pain;
• yellow complexion;
• increased sweating;
• discomfort in the liver;
• loss of strength and weakness.

Results of analyzes will enable an accurate diagnosis, so that will be the time treatment is started.

Chronic tonsillitis

In chronic inflammation of the tonsils often a low-grade fever. If the disease is not treated, the temperature can be reminded of the years currently. But the most dangerous thing that infections can spread throughout the body and provoke more serious pathology.

Helminthiasis (parasitic infestation)

The emergence of low grade temperature without any other symptoms may point to infection with worms. As a result of their activities in the body are formed foci of inflammation, which leads to an increase in temperature characteristics. Elevated temperatures may be combined with weight loss, dysfunction of the digestive system, weakness and quick fatigability.

Thyroid disease

In case of violation of the thyroid gland occurs hyperthyroidism. It is characterized by an acceleration of metabolic processes. By several degrees the temperature rises.

Are not excluded and other symptoms:

• weight loss;
• hair loss;
• increasing pressure;
• excessive sweating;
• diarrhea.

As a rule, the disease is easily diagnosed. Time spent treatment to avoid serious consequences.

Iron-deficiency anemia

Iron deficiency anemia can occur due to oncological diseases, chronic hemorrhage, infectious lesions, malnutrition.

When iron deficiency anemia subfebrile temperature manifests itself with:

• sudden darkening of the eyes;
• the disappearance of appetite;
• unpleasant sensations in the stomach;
• sleepiness;
• weakness;
• discomfort when swallowing food;
• dizziness;
• dry skin;
• marked deterioration of nails, hair;
• decreased immunity.

If you eliminate the root cause of iron deficiency, and a course of treatment, the body in a few months to get rid of anemia.

ankylosing spondylitis

Low-grade body temperature - it is a condition that often manifests itself in chronic lesions bones and joints of the spine (usually in the lumbar region): ankylosing spondylitis, or illness Spondylitis. The disease is incurable, can only partially alleviate its course.

autoimmune diseases

Autoimmune diseases (e.g., systemic lupus erythematosus, hyperthyroidism, Crohn's disease, rheumatoid arthritis, Horton's disease) is always accompanied by constant inflammation, because of which raised and kept temperature. Due to the failure of the body's immune system takes its own cells as foreign invaders and try to destroy them.

Completely impossible to get rid of these diseases, perhaps only a temporary improvement.

psychogenic causes

The temperature depends on the psyche. The causes of psychogenic nature, which can cause low-grade fever, are stress, severe emotional distress, neurosis. Using psychological questionnaires, diagnose the problem. And as its decisions prescribe sedatives or psychotherapy.

medicinal subfebrilitet

Subfebrile body temperature can manifest itself as a result of receiving the drugs. Such condition causes not only antibiotics (penicillin group, lincomycin), antihistamines and hormone preparations, narcotic analgesics.

It may also be anti-depressants. If it is determined that the temperature increase - a reaction to a specific drug, stop taking it. Or replaced with a more secure equivalent.

vasoneurosis

When the disease of the autonomic nervous system increased temperature can be maintained for a long time - for many years. It is not caused by inflammation, and psychosomatic causes. Sometimes low-grade fever suddenly runs by itself. On the background of change VSD pulse rate and blood pressure, there is sweating, muscle tone decreases.

Anemia

As low-grade fever, anemia is not a disease but a symptom.

The most common problems that trigger its development:

• malnutrition;
• improper functioning of the gastrointestinal tract;
• internal bleeding;
• helminth infections.

Anemia also can occur during pregnancy.

To which the doctor ask?

In order to establish the causes of the regular temperature increase should contact a physician. He will give a direction to the survey, to take required tests. And then, depending on the received diagnostic results, send to specialists: phthisiatrician, endocrinologist, infectious diseases, cancer, gastroenterologist.

Diagnostics

Before you give directions to the expert examination, begin every day to measure the temperature - every 3 hours. The results are recorded in a diary. Tracking performance lasts 2 weeks.

To determine what causes (infectious or non-infectious nature) caused by increasing temperature values, carry out a test with antipyretic drugs:

1. At rest, the measured temperature.
2. At higher values ​​of taking a pill antipyretic.
3. After 2 h. the measurement is repeated.

If rates have dropped to normal, there is a high probability of infection. When non-infectious pathologies indicators should remain at the same level. Fully trust this test is not necessary - the final conclusions made by experts. Standard diagnostic procedures are indicated in the table. In specific cases, the list can be reduced or supplemented.

analyzes	X-ray examinations and ultrasound	Other research and examinations
General blood analysis	radiography	ECG
Blood chemistry	Radiography of the sinuses	Mantoux test
General urine analysis	Ultrasound of internal organs	Survey of the gynecologist
Urinalysis Sterility	Thyroid ultrasound	inspection otolaryngologist
Daily urine	A visit to the dentist
Kal parasites
A blood test for hormones
Blood tests for infection (including syphilis, HIV, hepatitis)
Blood tests for tumor markers

Another test, which allows you to establish the nature of the problem supposedly called amidopirinovoy:

1. Before taking the drug measured temperature in the armpits, and rectally.
2. Make similar measurements after the adoption of means.
3. The test is continued for 3 days.

Methods of treatment depending on the disease

Specific treatment aimed solely at eliminating sub febrile temperature, no, because it is - just a symptom. If a state close to the feverish, brings severe discomfort, your doctor may recommend acceptance of antipyretics. But we should not use them on a daily basis.

The aim should be a statement of the correct diagnosis. After its establishment in due time the therapy. If the main reason for which the condition occurs subfebrile be eliminated, temperature readings back to normal.

In identifying serious diseases therapeutic measures can last a long time. In rare cases - with low-grade fever of unknown origin - it is impossible to make a diagnosis and prescribe treatment. Then the doctors admit that the rise in temperature triggered by psychological reasons.

whether prevention would help?

Take special preventive measures to protect themselves from subfebrile impossible. This practice does not exist, since the temperature rise occurs for various reasons. And more often than not it turns out to deal with them on their own - you need professional help.

Prevention is the responsible attitude to health: strengthening immunity, hardening and sports, to undergo regular medical examinations, establishing the regime of the day, rest and recuperation.

If there is such a symptom as a low-grade body temperature, it does not leave unattended. The first manifestations, without delay, it is important to be diagnosed - this will help in time to begin treatment and prevent the development of serious pathologies.
