What we aim to solve New!

Approximately 5% of the population worldwide, or 367 million people, suffer from excessive, uncontrollable sweating -- a medical condition called hyperhidrosis. Too many people suffer in silence, not realizing that their sweating is a treatable medical condition. Sufferers who do seek treatment do not always receive prompt diagnosis or care due to lack of physician awareness about hyperhidrosis, and the range of treatment options available. As a result, many are forced to develop compensating behaviors such as avoiding handshakes or certain social situations; or carrying a towel around with them. They report that their sweating has a profound effect on their emotions and confidence, which can negatively impact nearly every part of their lives-- social, professional, and at home. We want everyone to know that excessive sweating is a medical condition, we strive to improve the quality of life for those suffering from it, and we work to improve available treatment options as well.

We strive to improve the quality of life for the nearly 5% of the population—367 million people--with hyperhidrosis by helping to reduce the anxiety and social stigma associated with excessive sweating while also providing reliable, objective treatment and symptom management information. We want hyperhidrosis sufferers to recognize that their sweating is a medical condition so that they can discuss it with a knowledgeable healthcare provider. We also want to increase the number of healthcare providers who are aware of hyperhidrosis as a medical condition, and understand the most current treatment options. Improving the number and effectiveness of available treatment options and ensuring that treatments are affordable and accessible are other key goals. Finally, we strive to raise awareness of the emotional, practical, and economic impacts of hyperhidrosis so that, perhaps, these pervasive, long-standing secondary effects of the medical condition can be mitigated.

Our strategies include increasing public awareness about hyperhidrosis, educating healthcare providers about hyperhidrosis diagnosis and management, advocating for improved patient access to effective treatments, and promoting hyperhidrosis research among healthcare providers, scientists, and patients alike. Communicating reliable, up-to-date, useful information in an approachable manner via a variety of mediums – from low- to high-tech - is critical to helping us to meet our goals.

We increase public understanding of hyperhidrosis via our continuously evolving, expertly written and reviewed website. This website is visited by millions globally, and includes: (1) real patient stories and a powerful testimonial video, (2) a database of physicians familiar with hyperhidrosis, (3) in-depth insurance tools for patients and their physicians, and (4) descriptions of treatment options and sweat-managing products that can alleviate the impact of excessive sweating. We dispatch news blogs to over 50,000 subscribers, and answer emails to provide specific information and support. Our social media accounts enable sufferers from all over the world to connect. We facilitate physician education by holding medical education seminars and housing a plethora of on-line educational resources. We actively promote hyperhidrosis research by disseminating information about clinical trials, and keeping an up-to-date library of peer-reviewed, evidence-based research papers.

We will know that our organization is making progress by the number of visitors to our website; the number of phone calls and emails we receive for help and support; the number of physicians registered on our physician finder database and attending annual training meetings; the number of clinical trials underway; the increasing number of treatment options available; improvements made in insurance coverage of hyperhidrosis treatments; and the number of evidence-based sweat-related stories appearing in the general media.

Since 2003, we have developed: a content-rich website for both patients and physicians, another website dedicated entirely to teens with hyperhidrosis, a news blog with 50,000 subscribers, a searchable physician database, accredited medical education seminars attended by hundreds of healthcare providers, publications in peer-reviewed scientific journals, a “Know Sweat In School" program that brought information on excessive sweating to 10,000 school children and their school nurses, a powerful hyperhidrosis video filled with patient testimonials, and social media platforms so patients can make their voices heard. But there is more work to be done. We must increase public and healthcare provider awareness of hyperhidrosis and its serious quality-of-life impacts. We must also motivate medical researchers and industry professionals to develop more options for treatment. We aim to improve insurance coverage of treatments, and continue to reduce the stigma associated with this condition.
