Symptoms of disease - violation of organism thermoregulation

Disorders of thermoregulation - violations of the constant temperature of the body caused by dysfunction of the Central nervous system. Temperature homeostasis is one of the main functions of the hypothalamus, which contains a special temperature-sensitive neurons.

From the hypothalamus starts vegetative way, which if necessary can provide an increase in heat production, causing muscle tremors or scattering of excess heat.



Which diseases there is violation of organism thermoregulation

In the defeat of the hypothalamus, as well as the following from him to the stem of the brain or spinal cord ways disturbances occur moisture in the form of hyperthermia or hypothermia.

The heat of an organism into the environment depends on the ambient temperature, the amount of moisture (sweat), allocated by the organism because of the costs of heat for evaporation, on the severity of the performed work and the physical condition of the person.

At high air temperature and irradiation of the blood vessels of the body surface are increasing, in this case, the movement of blood - the main battery heat in the body - to the periphery (the surface of the body).

Due to such redistribution of the blood of the transfer of heat from the surface of a body increases significantly.

Violations of thermoregulation of the body may occur in the damage of the Central or peripheral level system of thermoregulation - bleeds or tumors in the area of hypothalamus, trauma, accompanied by damage to relevant pathways, etc.

Violation of thermoregulation accompanies many systemic diseases, usually manifesting increased body temperature or fever.

Increased body temperature is so reliable indicator of the disease, which is most often used in the clinic of the procedure became thermometry.

Temperature changes can be identified even in the absence of explicit febrile. They manifest themselves in the form of redness, blanching, sweating, tremor, abnormal sensations of heat or cold, and may also consist of an unstable fluctuations of body temperature within the normal range in patients with bed regime.

During physical work temporarily disrupted the balance between heat production and heat loss from the subsequent rapid restoration of normal temperature in a state of rest at the expense of long activation of mechanisms of heat transfer.

In fact, during prolonged physical activity expansion of the blood vessels of the skin in response to the increased temperature of the core of the body shall be terminated in order to maintain this temperature.

If fever adaptive capacity is reduced, so as to achieve a stable body temperature heat production is equal to the heat transfer, however, that, and the other is at the same level than that of the original. The blood flow in the peripheral blood vessels of the skin plays a more important role in the regulation of heat production and heat transfer than sweating.

If fever body temperature, defined thermoreceptors, low, therefore, the body reacts to it as for cooling.

A shiver leads to an increase in heat production, and the narrowing of blood vessels of the skin - to the decrease in heat emission. These processes allow us to explain arising in the beginning of fever, feeling cold or fever. And Vice versa, if you remove the causes of fever temperature decreases to normal, and the patient feels the heat. Compensatory reactions in this case are widening of the vessels of the skin, sweating, and suppressing the tremor.

At high temperature of the environment development of four clinical syndrome: heat cramps, heat exhaustion, heat injury at a voltage and thermal shock. Each of these conditions can distinguish on the basis of a variety of clinical manifestations, but between them there is a lot in common and these conditions can be considered as a variety of syndromes of one and the same origin.

Symptom complex of the thermal lesion develops at high temperatures (more than 32 degrees C) and high relative humidity (over 60%). The most vulnerable older persons, persons suffering from mental illness, alcoholism, taking antipsychotic, diuretics, antiholinergicakie drugs, as well as the people who are in areas with poor ventilation. Especially a lot of heat syndrome develops in the first days of heat, before it comes time for acclimatization.



Which doctor should I contact if there is a violation of organism thermoregulation

  • Neurologist


Are you experiencing violation of organism thermoregulation? You want to know more detailed information, or you need an inspection? Please sign up on reception to the doctor! Doctors will examine you, examine the external signs and help to determine the disease the symptoms, they will consult you and provide the necessary assistance. You can also call the doctor on the house.

Do you feel disrupted organism thermoregulation? You should be very careful approach to your health in general. People pay not enough attention to the symptoms of the disease and don't realize that these diseases can be critically dangerous. There are many diseases that in the beginning didn't manifest in our body, but in the end it turns out, unfortunately, it have already been treated too late. Every disease has its own specific features typical symptoms - called symptoms of the disease. Definition of symptoms is the first step in the diagnosis of diseases in general. You just need a few times a year to be screened by a doctor, not only to prevent a terrible disease, but also to maintain a healthy spirit in a body and the organism in general.
