Surgical Treatment
The operation to treat Hyperhidrosis, Endoscopic Thoracic Sympathectomy (ETS), is geared at eliminating the nerve impulses responsible for signaling the excessive production of sweat. ETS is a highly effective procedure, leading to a definitive cure in nearly 100% of all patients. When the surgery is performed by a skilled surgeon, the risk of complications is very low with the patient experiencing relatively little post-operative discomfort.

Endoscopic Thoracic Sympathectomy involves the removal of a small portion of the Sympathetic Chain which lies on the inside of the chest on either side of the spine. Total anesthesia is required. The procedure consists of making three tiny incisions in the armpit. A small scope inserted into the first incision will give the surgeons a detailed view of the Sympathetic Nerve Chain while the two surgical devices introduced into two other incisions will remove the defective portions of the nerve chain. The procedure is then repeated on the other side.

The entire process only takes about an hour and a half. Generally, the operation is done on an out-patient basis with a return to normal activity after just a few days. The resulting scar in the armpit is well-hidden and almost invisible.
Results

Relief to the patient after surgery is immediate and astonishing. Patients who just hours before fell asleep with cold, wet hands and feet wake up from anesthesia feeling warm and dry. With an overall success rate that is close to 100%, excessive hand sweat will be cured in almost all patients. Facial blushing and sweating will be eliminated in most cases with success rates at 95% and 90%, respectively. The outcome regarding relief of excessive foot sweat is not yet predictable, but in many cases Hyperhidrosis of the feet does improve as well. In addition to improvement or elimination of Hyperhidrosis, after surgery patients will feel calmer under stressful situations. Patients who suffer from chronic migraine headaches have noted a decrease in episodes. Stage fright is substantially reduced as is the severity of cardiac reactions to stress or anxiety. The positive results of ETS are reinforced by the high satisfaction rate of patients, averaging 98.5%.
Potential Side-Effects

The most common side-effect after ETS is Compensatory Sweating, an increase in sweating on other parts of the body (usually the trunk or on the thighs). Sweating in these less-exposed areas is, by the vast majority of patients regarded as a minor inconvenience and far more acceptable than the initial Hyperhidrosis experienced on exposed areas such as the face and hands.

Heredity has some effect on your ability to sweat, but being in good physical condition is usually a more important factor.
The majority of the body’s two to four million sweat glands are concentrated in the palms of the hands, making excessive sweating of the hands the most frequently encountered form of Hyperhidrosis.
Besides summer heat and exertion, perspiration can be triggered by strong emotions.
