The etiology, diagnosis, and management of hyperhidrosis: A comprehensive review

Hyperhidrosis (HH) is a dermatologic disorder defined by sweat production exceeding thermoregulatory needs. Clinically, HH is diagnosed when excess sweating creates significant emotional, physical, or social discomfort, causing a negative impact on the patient's quality of life. Existing data imply that this condition may affect at least 4.8% of the US population. The etiology of HH may stem from a complex autonomic nervous system dysfunction, resulting in neurogenic overactivity of otherwise normal eccrine sweat glands. Alternatively, HH may be a result of aberrant central control of emotions. This condition is categorized as primary or secondary HH. Approximately 93% of patients with HH have primary HH, of whom >90% have a typical focal and bilateral distribution affecting the axillae, palms, soles, and craniofacial areas. Secondary HH presents in a more generalized and asymmetric distribution and is generated by various underlying diseases or medications. Secondary causes of HH need to be excluded before diagnosing primary HH. Hyperhidrosis (HH) is a dermatologic disorder defined by sweat production exceeding thermoregulatory needs.
