What Causes Excessive Sweating?

Also known as hyperhidrosis, excessive sweating is a medical condition that affects an estimated 4.8 percent of individuals in the United States. Patients with this condition may sweat more than usual in cool weather or in response to stress or emotions such as anger or fear. Generally, hyperhidrosis begins before individuals are twenty-five years old, and patients experience symptoms at least once a week. The sweating associated with this condition may occur for no known reason over six months or more, and the patient will frequently sweat on both sides of their body in similar amounts.
