The next option, iontophoresis, is administered at home using a machine that works by immersing the affected areas into tap water and then passing a small electrical current through the skin to temporarily disrupt sweat production. This treatment is most appropriate for hands and feet and on average decreases sweating of the treated area by 50%.
When other medical treatments fail to control excessive sweating, surgery may be an option. Dr. Minars does not perform this surgery. Patients who require and are appropriate for this procedure are referred to the surgeons of the Memorial Hyperhidrosis Center who offer a highly advanced, minimally invasive outpatient procedure called endoscopic thoracic sympathectomy (ETS).
