Excessive sweating, or hyperhidrosis, is a condition where the body produces more sweat than necessary to regulate temperature. It commonly affects the underarms, hands, feet, and face, often interfering with daily activities and confidence. Hyperhidrosis may occur without an identifiable cause or as a result of an underlying condition. While not harmful, it can be uncomfortable and socially disruptive. Modern treatments help control excessive sweating, improving comfort and quality of life.
