What is Excessive sweating?
Hyperhidrosis is the condition characterized by abnormally increased sweating/perspiration, in excess of that required for regulation of body temperature. It is associated with a significant quality of life burden from a psychological, emotional, and social perspective. As such, it has been referred to as the 'silent handicap'.
The words diaphoresis and hidrosis both can mean either perspiration (in which sense they are synonymous with sweating) or excessive perspiration (in which sense they can be either synonymous with hyperhidrosis or differentiable from it only by clinical criteria involved in narrow specialist senses of the words).
