Why is it freezing?

Fever is the body's response tooccurrence in it of any viruses, microbes, bacterial poisons, and also the reasons of non-infectious character, for example, a bruise of a brain or hysteria. This pathological process entails an increase in body temperature and a change in its thermoregulation. The person frosts, there is a chill, weakness and aches in the bones.

In itself, a febrile state is notdisease, although there are diseases in the name that contain the term "fever" (for example, Ebola haemorrhagic fever). In other cases it is a symptom that indicates the presence of the disease. Let us consider in more detail why a person is freezing.

The causes of the violation of body thermoregulation

In the human hypothalamus is locatedThermoregulating center, responsible for heat transfer and heat production. By a complex system of control established by the brain, a balance is observed between these two processes. Infectiousness, swelling, intoxication and other effects can disrupt it.

If you are sick, a person feels that it is freezing, the reasons why this happens can be as follows:

• Infectious and inflammatory diseases of internal organs:
  • abscesses of the liver and kidneys;
  • pneumonia;
  • cholangitis;
  • intestinal infections, etc.
• Endocarditis. When infectious human endocarditis freezes long before the symptoms of the underlying disease, such as heart murmurs, thromboembolism, etc. In patients with weakened immune defense, the cause of endocarditis can be fungi. When setting such a diagnosis, the therapist is prescribed treatment - the course of antibacterial drugs after determining the sensitivity to the pathogen.
• Tuberculosis. Learn about the tuberculosis of the liver, adrenal glands, kidneys, peritoneum, lymph nodes and some other organs can sometimes only by the presence of fever. Sometimes it is the only symptom of these diseases. Most other organs from tuberculosis suffer from lungs, which is detected with the help of an X-ray. No less effective is the bacteriological method of research - mycobacterium tuberculosis is found in sputum, urine, cerebrospinal fluid and gastric juice.

Other causes of fever include:

• malfunctions in the immune system;
• thrombosis of blood vessels;
• taking certain medications (eg, interleukins);
• tumor processes;
• diseases of the endocrine nature;
• hemorrhage and trauma in the skull;
• heredity.

How to treat a fever

Physicians distinguish between two types of fever: "White" and "pink." When the "white" is observed extraordinary pallor of the skin, their marbling and dryness. The patient's hands and feet are cold, the pulse is rapid, the pressure is higher than normal. This condition is dangerous and a number of actions are carried out to transfer the fever from "white" to "pink."

The "pink" fever is different. There is redness of the skin, humidity and body temperature increase. Heat is intensively given off by the skin and the danger of overheating is low.

If such symptoms are observed, thencall a doctor. Without medical assistance, the situation can get out of hand and the temperature will rise to critical levels. Prior to the arrival of a specialist, you should:

• Drink more fluids. The best are berry and fruit fruit drinks, compote of dried fruits, decoctions and juices. The intake of food is not forbidden, but preference should be given to easily assimilated carbohydrates.
• At a temperature above 39 ° C, you can wipe the patient with a sponge soaked in warm water (at least 30-32 ° C). This method is practiced with a "white" fever.
• Give antipyretics before the arrival of a doctor is not recommended, since their action can "obscure" the clinical picture of the disease.
