ABSTRACT
The clinical spectrum of sweating disorders includes sudomotor excess and deficiency. Hyperhidrosis is characterized by sweating beyond that required to maintain a constant internal body temperature. Hypohidrosis and anhidrosis are distinguished by a reduced or absent ability to generate sweat for the purpose of evaporative heat dissipation. Whereas hyperhidrosis is usually benign, anhidrosis may predispose to hyperthermia.
