Dr. David Nielson, MD, FACS - Hyperhidrosis Specialist, Excessive Sweating Expert


hyperhidrosis doctor  
Society of Thoracic Surgeons  

Dr. David Nielson
Texas based cardio-thoracic surgeon who specializes in micro-endoscopic chest surgery. Dr. Nielson is widely known as a hyperhydrosis expert and sweating specialist with his innovative, least invasive treatment for patients who suffer from (excessive sweating of the hands, face, and/or armpits, Raynaud’s Syndrome, and Facial Blushing. These conditions are all connected to an over-active sympathetic nerve chain.  Micro-endoscopic thoracic sympathectomy (Micro ETS), created by Dr. Nielson, is the least invasive, most advanced surgery for people suffering from these ailments.  One of the most experienced endoscopic thoracic surgeon performing ETS surgery, Dr. Nielson emphasizes that extensive ETS surgical experience is essential to eliminating excessive sweating of the hands, face, and/or armpits.

Dr. Nielson's Micro ETS procedure has the quickest recovery time and has a high success rate for those suffering from hyperhidrosis of the hands. During the procedure, Dr. Nielson makes a single incision, one-twelfth of an inch per side , under each arm and inserts a 2mm scope. Nielson compares the size of his instruments to angel hair pasta. Once Dr. Nielson identifies the sympathetic nerve, he precisely divides it to instantly lessen hyperhidrosis symptoms and bring warmth to cold hands. The procedure takes 30 minutes. The patient is able to leave two to four hours after the procedure.
