Assessing the Effect of Patient Characteristics on Treatment Response in Primary Hyperhidrosis

This study will describe the treatment of hyperhidrosis (excessive sweating) in clinical practice and explore the effect of patient characteristics on treatment response. This study will follow 200 people with hyperhidrosis over 18 months. Anyone with primary hyperhidrosis (excessive sweating not due to another medical condition) over the age of 12 may participate. Study participants will have multiple office visits during which they will asked to rate the severity of their sweat production in multiple areas (i.e. underarms, hands, feet), answer a questionnaire regarding their disease and treatment, and undergo a non-invasive measurement of sweat production called gravimetry. Gravimetry is performed by placing absorbent material in an area, such as the underarms, for a set amount of time and then measuring the amount of sweat collected. In between clinic visits, study participants will be contacted electronically to answer several questions regarding their disease and treatment.
