Even those who know almost nothing about the structure and functioning of the human body are aware of the sweat glands. As a rule, they are considered exclusively a source of an unpleasant odor and unaesthetic secretions, although their role in the thermoregulation of the body is recognized. Nevertheless, sweat glands play a significant role in the functioning of the excretory system, and malfunctions in their functioning can cause discomfort to a person and cause a number of skin diseases. About what are the diseases of the sweat glands & nbsp; and why they are dangerous, read on Estet-portal.com.

What determines the work of the sweat glands and the composition of sweat

Sweat glands are located unevenly on the human body, and their work is regulated by the nervous system. The amount of sweat produced depends on the ambient temperature – even in a motionless person in a cold room, the sweat glands work, but not all and not intensively. Men tend to sweat more than women. Chemical Composition  sweat is individual for each person, and it may differ in different parts of the body.  So, with sweat, human skin releases more than 250 different substances, sweat on the neck contains more salts, and under the armpits – more lipids. In patients with diabetes, sweat contains an increased level of glucose, and in athletes after training – lots of lactic acid. Of course, the composition of sweat is affected by food – it changes under the influence of alcohol,

Sweating can be of several types:

    thermoregulation – sweat glands are activated of the entire skin, is realized due to the expansion of skin vessels & nbsp; to cool the body in case of overheating in a hot environment, during heavy physical or sports stress, in febrile conditions;
  • psychogenic – active sweat glands of the palms, feet, face, armpits, realized due to spasm of skin vessels as a reaction to mental or emotional stress;
  • food – sweat glands are activated when eating at any temperature, but especially under the influence of hot dishes, alcohol, extractives from spices.
Diseases of the sweat glands and problems with sweating

Sweat glands are involved in the regulation of metabolism and water-salt balance, remove metabolic products from the body, and therefore, based on their work, one can often assume which organs and systems are malfunctioning. But sometimes there may be diseases associated directly with sweating and the work of the sweat glands themselves.

Anhidrosis – lack of sweating; possible causes of anhidrosis: aplasia of sweat glands, tumors and other lesions of the spinal cord, toxicosis during pregnancy and poisoning, dehydration of the orginismak.

Oligohidrosis – weak sweating, insufficient for the functioning of the body; causes: ichthyosis and some other skin diseases, old age.

Hydradenitis – purulent inflammation of the sweat glands; causes: blockage of the gland, hormonal failure, bacterial infection, immunodeficiency.

Hyperhidrosis – excessive sweating; causes: infectious diseases, tuberculosis, rheumatism; neglect of personal hygiene, psychological factors; local  hyperhidrosis can manifest itself with flat feet, eczema, psoriasis, fungal infections.

Osmidrosis – excretion of sweat with a fetid odor; causes: endocrine diseases, menstrual disorders, diseases of the urinary system, poor hygiene.

Chromhidrosis – secretion of sweat dyed in uncharacteristic colors; reasons: accumulation of metal salts (copper, cobalt) in the body due to professional contact with these substances.

Sweating – inflammation of the sweat glands, which occurs due to intense sweating and blockage of the ducts; reason: overheating of the body in hot conditions.

All problems with sweating are solved individually with each of the patients, depending on the general state of health and the reasons that caused the disease of the sweat glands.
