About the International Hyperhidrosis Society

Founded in 2003 by an elite team of world-respected physicians and experts in hyperhidrosis research, the International Hyperhidrosis Society is the only independent, non-profit, global organization that strives to improve quality of life among those affected by excessive sweating. The International Hyperhidrosis Society knows no boundaries; it is composed of people from all over the world, making it a true global network of understanding, advocacy, information, and resources. We are a registered charity under section 501(c)3 of the IRS tax code and 100% of your donation is tax deductible (for U.S. residents). Each member of our Board of Directors is a dedicated volunteer.

Our mission is to reduce the symptoms, anxiety, and social stigma associated with excessive sweating by improving the information, support, and treatment available to the millions (3% of the population) of children, teens, and adults affected by hyperhidrosis worldwide. As part of our mission, we promote hyperhidrosis research, educate healthcare professionals in optimal hyperhidrosis diagnosis and management, raise awareness about the condition's emotional and economic impacts, and advocate for improved patient access to effective treatments, all while also increasing public understanding of this debilitating medical condition. We also build programs that connect those who suffer from hyperhidrosis with those who provide care.
