Excessive sweating, also known as hyperhidrosis, is a rare condition that causes sweating on the hands, feet, armpits, face and genital area, or all over the entire body. The cause of this condition is unknown, although it often runs in families and begins during childhood.
Patients with hyperhidrosis may sweat all over their body or in certain areas. Their skin may become white and wrinkled or red and irritated as a result of the constant moisture, and may develop an odor as well. Living with hyperhidrosis often causes patients to feel embarrassed, awkward and self-conscious, especially during social situations.
