Hyperhidrosis
Pronunciation: hy-per-hy-DROH-sis
A condition of excessive sweating beyond what is physiologically required for thermoregulation, treated in cosmetic dermatology with intradermal botulinum toxin injections.
Full Definition
Hyperhidrosis is classified as primary (idiopathic, focal) or secondary (generalised, caused by an underlying condition). In cosmetic and medical dermatology, the axillary, palmar, and plantar forms are most commonly addressed. Botulinum toxin injections into the affected area temporarily block eccrine sweat gland activity and represent a licensed treatment indication in many jurisdictions. Editors should note the correct spelling ends in '-osis' (not '-osis' or '-asis') and should verify whether a document refers to primary focal hyperhidrosis (the cosmetic indication) or secondary forms. The term appears in consent forms, clinical outcome scales, and product prescribing information.
Usage
Usage note: Distinguish primary focal hyperhidrosis (cosmetic/medical indication) from secondary generalised hyperhidrosis in all clinical documents.
