International Hyperhidrosis Society

About the International Hyperhidrosis Society


Hyperhidrosis (extreme, uncontrollable sweating affecting 4.8% of people) is often misunderstood, misrepresented and mismanaged, but for the past 15 years the International Hyperhidrosis Society (IHhS) has been bringing the full range of stakeholders to the table to transform missed opportunities into an impactful mission.

From individual sufferers and health providers, to pharma, biotech and regulatory bodies, IHhS provides and fosters advocacy that’s collaborative and cross-pollinating for meaningful improvements in hyperhidrosis diagnosis, care, and understanding.

Although excessive sweating continues to cause excessive suffering, we’re working towards a cure. 

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 and... we know no boundaries. Our community brings together people from all over the world; creating a global network for advocacy, support, and information-sharing. 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 of children, teens, and adults affected by hyperhidrosis worldwide. As part of our mission, we promote hyperhidrosis research, educate healthcare professionals in optimal, up-to-date hyperhidrosis diagnosis and management, raise awareness about this condition's emotional, economic, and life impacts, and advocate for improved patient access to effective treatments, all while also listening carefully to the voices of hyperhidrosis sufferers and increasing public understanding of this debilitating medical condition.
