Symptoms
By Mayo Clinic staffMost people sweat when they exercise or exert themselves, are in a hot environment, or are nervous, anxious or under stress. The excessive sweating experienced with hyperhidrosis far exceeds such normal sweating.
Hyperhidrosis usually affects the hands, feet, underarms and sometimes the face. Rarely, the entire body is affected. The excessive sweat may soak through clothes or drip off your hands. Episodes usually occur at least once a week without an obvious reason.
