Excessive sweating is when you sweat more than you might expect based on the surrounding temperature or your activity level or stress. Excessive sweating can disrupt daily activities and cause social anxiety or embarrassment.

Excessive sweating, or hyperhidrosis (hi-pur-hi-DROE-sis), can affect your entire body or just certain areas, such as your palms, soles, underarms or face. The type that typically affects the hands and feet causes at least one episode a week, during waking hours.
