Hyperhidrosis is a condition that causes excessive sweating beyond what the body needs to regulate temperature. It most commonly affects the underarms, hands, feet, or face.

For many people, sweating can occur even when the temperature is cool or when they are not physically active.

Excessive sweating can interfere with clothing choices, work activities, and social situations. Many people with hyperhidrosis find that standard antiperspirants or over-the-counter treatments do not provide enough relief.
