Fever is called increase body temperature above 370C. Thus appears a defensive reaction to infection, inflammation, cancer, or to allergens.

Most adult human cause temperature rise are infectious diseases, conditions associated with the formation of antibodies against its own body (autoimmune disease), malignant tumors, etc.

What if this happens

The normal body temperature of a healthy person can fluctuate throughout the day — from 360From 6:00 in the morning to 36.90C.16-18 pm. In children and the elderly in the morning and did the norm is temperature Body 356-36,00S.

An increase in temperature is caused by special agents — pyrogens. They can be both pathogens and their metabolic products — toxins. They stimulate organism to develop their own pyrogens. This deals with a certain type of white blood cells (WBCs) — monocytes.

Body temperature in our body controls the hypothalamus. Reduce the loss of body heat is achieved through the redistribution of blood from the surface of the skin to the internal organs. Thus there is a fever — organism trying to compensate for the heat loss of muscle contraction. When the temperature decreases to a normal level, the excess heat is removed by sweating and hot flushes back toward the skin surface.

It should be remembered that high temperature increases the body's need for oxygen by 7% for each degree above 36.60C, so it is dangerous for the "core" and people with diseased lungs. A serious increase body temperature may even lead to dysfunction of the brain.

Diagnostics

In rare cases, that the behavior of the temperature can be assumed diagnosis — for example, temperature rise characteristic of malaria in a day or every third day.

In addition, when viewed from the patient's physician interested preceding symptoms and diseases, taking medication, the possibility of contact with sick people, traveling (there are a number of tropical infections).

Some studies of blood:

  • Antibody against certain microorganisms;
  • Blood cultures on various culture media for the purpose of determining the presence of a bacterial or fungal infection;
  • determining the number of leukocytes in blood. The so-called WBC (proportional content of different varieties of white blood cells in the blood) allows you to get additional information. For example, an increase in the number of neutrophils may indicate an acute bacterial infection, eosinophils — infection of the round or tape worms, etc.

Treatment

Increased temperature body — this is a sign that the body is fighting an illness, so do not always be in a hurry to shoot down the temperature. Therefore, if there is no specific complications (headache, convulsions in children), the temperature should begin to shoot down after passing a threshold of 38.00S.

However, if the child has previously had attacks of convulsions during high temperature (febrile convulsions), then, of course, necessary to reduce the temperature. Monitor the temperature and knock it if necessary, and in adults with heart or lung disease.

The most famous are paracetamol antipyretic and nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin. However, children from better keep aspirin because there is a perception that it increases the risk of developing a rare but dangerous Reye's syndrome — a disease which is accompanied by inflammation of the brain.
