The Sweat glands perform an important function of thermoregulation of an organism and the withdrawal of products of metabolism and water from it to the surface of the skin. They are similar to a ball rolled tubes from which depart, in fact, the ducts to the skin surface. In humans, the number of sweat glands may reach 2.5 million. They are distributed unevenly through the body: in some places there is a large concentration (armpits, on the palms, on the soles of feet), and there are places where they do not. In particular, the sweat glands are absent in males on the glans penis. In fact, in women they are not in the same place: in the field of large and small labia.

Is not only the density of sweat glands (per square centimeter of the skin surface may account for from 55 to 400 pieces), but the depth. There are sweat glands, which are located deep in the dermis, others can be placed directly in the subcutaneous fat.

Types of sweat glands

Eccrine sweat glands are responsible for thermoregulation and are located mainly in the subcutaneous and skin layers. In secret they produce 98% water, the rest is, mostly, sodium chloride, obtained from blood plasma. The work of the exocrine (eccrine) glands control the nervous and hormonal system. The amount of sweat produced depends on many factors and can vary from 250 to 800 ml per day.

Apocrine sweat glands produce the very secret by which to identify each person. It is a viscous substance with specific smell. Apocrine glands begin to work immediately, they aktiviziruyutsya during puberty. The size of apocrine glands larger than eccrine, and is located mainly in the anogenital, axillary area and breast. They have a slightly different mechanism of secretion, although a small part in thermoregulation, they also accept.

What sick sweat glands

The Most common two serious diseases: anhidrosis and hyperhidrosis, each of which leads to its unpleasant consequences. May develop inflammation of the sweat glands which usually treated with anti-inflammatory drugs local action.

Anhidrosis – this disease, when the secretion of sweat at all stops. Can cause some underlying disease. Distinguish 4 types anhydrase:

  • Congenital -due to pathology (aplasia or hypoplasia) glands;
  • Acute - can develop due to dehydration of the organism, e.g. after intoxication;
  • Chronic, may be congenital or develop in violation of the nervous system;
  • Rain - is so named because it is more common in people living in the tropics, it occurs from blockage of sweat ducts with dust.

Anhidrosis may develop due to disease of the skin in the aging process, diabetes, or spinal injury (if spinal cord is damaged), hereditary diseases.

So sick in the first place to avoid overheating. Because violation of the mechanism of thermoregulation, increases the likelihood of heat exhaustion when a person is in a hot place. Contraindicated exercise. Treat anhidrosis multivitamins, retinol, apathetic ointments with moisturizing characteristics.

Hyperhidrosis – it is a disease the opposite of the previous one. That is sweat stand out too much and it can give a lot of trouble. Hyperhidrosis can be localized in separate areas or spread to the whole body. Can occur during exercise or develop due to serious diseases, such as nervous system. More common hyperhidrosis, localized in the armpits, on the inner surface of the palms and on the soles of the feet.

With hyperhidrosis may involve removing the sweat glands with a minimally invasive subcutaneous curettage. Glands processed with sodium chloride (saline) and are sucked out through the incisions with a special cannula.
