Excessive sweating or hyperhidrosis is a state in which an individual has increased perspiration than that is required for proper control of body temperature.

Sweating is a natural process required for the control of one’s body temperature. The secretion of sweat is controlled by the Sympathetic Nervous System. In some people this system works at a very high activity level above what is needed to keep the body temperature constant. This affliction is called hyperhidrosis or excessive sweating.

Excessive sweating can occur in certain parts of the body like armpit, feet, hands, and the groin. These areas are among the most active in sweating because of high concentration of sweat glands although any part of the body can be affected. Hyperhidrosis is divided into primary condition, in which it is inherited and is noticed early in life or secondary hyperhirosis which is brought about by medical condition occurring later in life. These include obesity, menopause and other psychiatric complications.

The genesis of primary hyperhidrosis is not clear but is likely to be caused by sympathetic nervous system disorder. Anxiety worsens the situation for many sufferers. Other factors like certain foods & drinks, nicotine, caffeine, and smells play a role in initiating excessive sweating.
