ABSTRACT
Sweating is a physiological response of the body for thermal regulation influenced by the change in skin temperature (1) mediated by sympathetic nervous system. In about 1% of the population, the sympathetic nervous system is overactive, causing certain areas of the body to sweat at inappropriate times and beyond what is necessary to maintain thermal regulation. This disorder is known as primary hyperhidrosis (2). The definition of hyperhidrosis as excessive sweating is subjective. It is defined quantitatively as the production of more than 100 mg of sweat in 1 axilla over 5 minutes (3). Excessive sweating (hyperhydrosis) or its absence (anhydrosis) are distressing, often attributed to organic causes requiring investigation and treatment (4). Hyperhidrosis may be focal or generalized. Focal hyperhidrosis is most often essential, or idiopathic, and results from a neurogenic overactivity of the sweat glands in the affected area.
