Hyperhidrosis is a fairly common form of unexplained functional localized abnormal hyperhidrosis, which has also become primary hyperhidrosis of the hands and feet. Young people growing up in subtropical areas are especially prone to this problem. The secretion of sweat glands is controlled by the sympathetic nerves and occurs most often when the sympathetic nerves are overstimulated, such as tension, excitement, stress, or summer heat. Many patients have a family history of the condition, but it is not always passed on to the next generation. There are two types of treatment for hand sweating: medical and surgical. Internal medicine uses drugs that inhibit the sympathetic nervous system to control symptoms, which often have side effects such as dry mouth or gastrointestinal disturbances, and are prone to relapse after discontinuing the medication. Because of the limitations of medical treatment, surgical treatment has become the trend in the treatment of hand sweating. Surgical treatments are divided into open-heart and minimally invasive methods. Traditional open heart surgery is gradually being phased out due to long incisions, high trauma, long operation time, heavy pain and long hospitalization. Minimally invasive surgery has small wounds, does not require stitches, takes less than half an hour to perform, has a quick post-operative recovery, and the success rate of the surgery can be as high as 99%. “Thoracoscopic Bilateral Thoracic Sympathetic Ganglionectomy” is the most commonly used minimally invasive surgical procedure today, which can be completed by making two tiny incisions of about 0.3cm in diameter in each armpit. The incisions are small, the pain is small, the scar is small and does not affect the aesthetics, usually about 2 days after the operation, the vast majority of patients immediately disappear after the operation. Some patients have compensatory sweating in the forehead, buttocks and abdomen, but most of them have mild symptoms and can tolerate it. Patients can quickly integrate into society and rebuild self-confidence, and the recurrence rate is extremely low.
