With fever, sweat is hot and usually appears on the hyperemia skin, while in conditions accompanied by hypersympathicotonia, arterial hypotension sweat is cold, sticky, and the skin is pale.
Sometimes excessive sweating is accompanied by a special rash (sweating) in the form of vesicles the size of a poppy seed covering the skin, like dew. The sweating is caused by a blockage of the excretory ducts of sweat glands.
Increased sweating can be caused by the following reasons.
- Constitutional features.
- Fever: in some diseases, increased sweating occurs only during a period of lower body temperature (croupous pneumonia, sepsis, malaria). Tuberculosis and HIV infection are characterized by a symptom of nocturnal pouring sweat associated with prolonged subfebrile fever. This symptom is also observed in infectious endocarditis. Conversely, with scarlet fever, typhoid fever, an increase in sweating is not typical.
- Hyperthyroidism (increase in the blood levels of thyroid hormones).
- Hypoglycaemia - excessive skin moisture serves as one of the differential signs of hypoglycemic coma from other comas in diabetes mellitus (with a high content of glucose in the blood).
- "Tides" in women during menopause.
- Conditions accompanied by an increase in the tone of the sympathetic part of the nervous system: mental excitement, pain, fear.
- Vascular collapse with arterial hypotension.
- Pronounced hypercapnia - with suffocation, pronounced dyspnea, in agonal states.
