Hyperhidrosis is abnormal excessive sweating.
Excessive sweating, also known as hyperhidrosis, is an embarrassing condition that can have dramatic negative effects on peoples’ lives. It can affect most areas of the body, but it is usually a major problem in one or two main areas.
Hyperhidrosis is the excessive production of the watery sweat. This sweat causes the damp patches on clothes, and in severe cases, beads of sweat form and can drip down the body from the affected area.This sweat is produced by the Eccrine glands. It’s main purpose is to cool the body.
This condition is not to be confused with smelly sweat – properly called Bromhidrosis – which is a more greasy sweat of low volume that has a distinctive – and often nasty – smell. Bromhidrosis is formed by the Apocrine glands. These produce a greasy substance called sebum that is discharged into hair follicles.
The condition is controlled by the sympathetic nervous system, although many other factors also influence it – such as heat or local heat, psychological effects (embarrassment or fear), some hormones, some drugs, some sorts of food.
