L74.3: Miliaria, unspecified
Sweat glands are located just below the surface of the skin and are distributed throughout the body and produce sweat. Sweat cools the skin down when it’s too warm. Certain substances are also excreted with the sweat and the skin is kept supple. The sweat reaches the surface of the skin from the sweat gland through small pores. These small pores can become closed, for example, in extreme heat or as a result of greasy creams. The sweat can then no longer drain properly from the affected areas and collects in the skin.
As a result, skin lesions form where blisters or papules can be seen on the skin, for example.
