Diagnosis and Management of Primary Hyperhidrosis: Practical Guidance and Current Therapy Update.

Hyperhidrosis is a chronic medical condition characterized by excessive sweating beyond that which is necessary for thermoregulatory homeostasis. It is estimated to occur in 4.8% of the U.S. population (~15.3 million people) but is both underreported and underdiagnosed. With the busy practitioner and dermatology resident in mind, we provide here a disease state primer for hyperhidrosis, a top-line review of the breadth of literature underscoring the overall burden of the disease, a practical guide to differential diagnosis, and an update on current treatment approaches, including for the most common form of the condition, primary axillary hyperhidrosis. In addition, a case study is presented to provide a real-life perspective from the clinic on the importance of early and effective management strategies for those suffering with hyperhidrosis.
