|Other names||Polyhidrosis, sudorrhea|
Hyperhidrosis is a condition characterized by abnormally increased sweating, in excess of that required for regulation of body temperature. Although primarily a physical burden, hyperhidrosis can deteriorate quality of life from a psychological, emotional, and social perspective. It has been called by some 'the silent handicap'.
Both the words diaphoresis and hidrosis can mean either perspiration (in which sense they are synonymous with sweating) or excessive perspiration, in which case they refer to a specific, narrowly defined, clinical disorder.
