Hyperhidrosis is a condition that causes excessive sweating, usually of the palms but also of the axillae and feet.
There are a number of conservative treatment options such as topical antiperspirant, iontophoresis and botox injections.
Surgery (thoracoscopic sympathectomy) can be performed as an overnight procedure with very low risk of complications. The long term results with surgery show that 80% of patients with palmar hyperhidrosis are satisfied with the results. Patients with axillary or plantar hyperhidrosis have a less reliable response.
A referral to a thoracic surgeon to discuss the risks and benefits in any case is worthwhile.
