Hyperhidrosis is a condition that causes the body to sweat uncontrollably and unpredictably. Most commonly the hands, feet, groin, and underarms are affected; however, hyperhidrosis can also occur on the face and, rarely, the entire body.

The cause of hyperhidrosis is unknown but doctors believe that an over-reactive sympathetic nerve response is the primary cause. High emotion, smells, sounds, certain foods and drinks, caffeine, or nicotine can trigger episodes. Hyperhidrosis can also occur with other conditions like Parkinson’s disease,  congestive heart failure, and  diabetes.
