Abstract: Hyperhidrosis (HH) is a disorder of the eccrine sweat glands causing excessive sweating. It is caused by hyperactivity of the sympathetic nervous system resulting in excessive release of acetylcholine and activation of the sweat glands. Primary essential HH is thought to have a large genetic component, while secondary HH is the result of an underlying condition or medications. HH will often cause excessive sweating in areas with a high density of eccrine sweat glands that include the palms, soles, face, head, or axillae. Diagnosis is largely based on history and physical which can help differentiate between primary and secondary HH. Hyperhidrosis can have a significant impact on quality of life. Management includes identifying and avoiding triggers, the use of topical antiperspirants, and advanced therapies in recalcitrant cases (such as tap water iontophoresis, botulinum toxin injection and surgical options).
Key Words: hyperhidrosis (HH), primary (essential) hyperhidrosis, secondary hyperhidrosis, excessive sweating, eccrine sweat gland.
