Endoscopic Thoracic Sympathectomy (also called ETS) is another procedure for excessive sweating which is performed under general anesthesia. Using a fiberoptic surgical tube inserted through the neck or the underarm, a surgeon cuts the nerve ganglion near the spinal cord that is responsible for transmitting messages to the sweat glands. This procedure is mainly for excessive face and hand sweating, and can be effective, but compensatory sweating (sweating in other areas) and gustatory sweating (sweating when eating or smelling spicy foods) are common side effects. There are also reports that ETS can permanently lower the patients heart rate, so athletes should consider carefully before choosing this procedure.
