Many patients with hyperhidrosis try topical medications or herbal remedies to ease their condition, but these have only temporary or no benefit. Fortunately, effective treatments are available.
UCSF dermatologists use botulinum toxin (Botox) injections to treat hyperhidrosis. The injections temporarily block a chemical in the body that stimulates the sweat glands, and will reduce sweating for about four to six months.
The treatment is relatively painless, and most patients do not need anesthesia. Doctors can apply anesthetic cream or ice to the skin before the injections, if desired. Patients typically resume their regular activities immediately after the treatment.
Surgical interruption of the sympathetic nerve chain offers proven, long-term results. These nerves primarily affect blood flow to the skin and the function of the sweat glands. Interrupting the sympathetic nerves in the chest results in dilation of the veins and arteries in the arm and hand as well as the complete blockage of sweating.
A minimally invasive procedure called endoscopic thoracic sympathectomy (ETS) was developed to treat hyperhidrosis. Using very small incisions, the sympathetic chain is cut or clamped to eliminate the excessive sympathetic nerve activity. The ETS procedure may be done on an outpatient basis with quicker recovery and less scarring than open surgery. The procedure is highly effective in eliminating excessive sweating of the hands in more than 98 percent of patients. In addition, the risk of complications is very low. ETS also can be used in some patients with axillary hyperhidrosis, or excessive sweating of the armpits.
UCSF surgeons have significant experience in treating hyperhidrosis using ETS. We can perform ETS on both sides of the body during a single operation if needed. The operation requires general anesthesia, and two 5 millimeter incisions on each side. Most patients leave the hospital in less than 24 hours and recover completely within two weeks.
