|Underarm sweating is a normal process and is something that most people have to deal with. Unlike many other types of sweating, underarm sweating only begins around puberty and during the first month or two the sweating is generally excessive. In time, this sweating decreases down to a normal and more manageable level.
For some people however, the sweating remains excessive and it can become quite an annoying and embarrassing problem having to deal with large sweat marks on clothing, and managing the body odor that is often associated with underarm sweating. The sweat glands in the armpits differ to the sweat glands in most other areas of the body.
Unlike the eccrine sweat glands, which are all over the body and concentrated in areas such as the head, hands, and feet, the glands present under the arms and in the groin area are called apocrine glands. Where eccrine glands excrete mainly water and salts, the sweat produced by the apocrine glands also contains other substances such as carbohydrates, proteins, fatty substances and pheromones.
The sweat produced in these glands is therefore often associated with body odor as it attracts bacteria and when the compounds are broken down, body odor is the result. When underarm sweating becomes excessive it is referred to as auxiliary hyperhidrosis.
