In daily life, we can often see some of these friends around us, their palms are mostly wet, no matter the summer heat, or cold, palms, soles and armpits are always sweaty, wet and cold, and sometimes dripping beads of sweat, more serious when emotional tension. Often when writing the paper blotting wet, typing the keyboard dripping wet, more afraid to shake hands with others, in a crowded occasion, in a meeting to make a report, in meeting strangers, in meeting acquaintances leadership, in nervous excitement, in sports, in meeting the opposite sex, in talking about sensitive topics, sometimes somehow also appear full of sweat, full face red and hot. The symptoms often cause serious problems in school, work or social life. In fact, this condition is medically known as hyperhidrosis of the hands, or hand sweating for short. We know that the secretion of sweat glands is controlled by sympathetic nerves, and hand sweating is caused by unexplained sympathetic overstimulation, such as tension, excitement, stress or abnormal increase in palm sweating due to high summer temperatures. Hand sweating occurs in most children and becomes more severe in adolescence. Most patients with hand sweating are healthy and normal except for sweaty hands, and most also have excessive sweating on the soles of the feet or in the armpits. It is a congenital defect. These are not serious diseases, but excessive sweating and/or blushing makes the patient friend in daily helplessness, anxiety or panic, bringing great inconvenience to work, social and life, and seriously affecting the patient’s self-confidence. It can be said that excessive sweating is not a disease, but it is annoying to the point of killing! For a long time, the treatment of hand sweating has been a difficult problem, with limited treatment methods and inaccurate results. The treatment of hand sweating is divided into two methods: medical and surgical. The sympathetic nervous system inhibitors used in internal medicine often have side effects such as dry mouth or gastrointestinal dysfunction, which affects long-term use. Topically applied medications are also limited in duration and need to be reapplied from time to time, and are not as effective. All in all, internal medicine methods have their limitations. Surgical treatment: The most critical point is to surgically cut off the sympathetic nerves that control the sweat glands in the hands, which are located in the second and third vertebrae of the thoracic spine, that is, on both sides of the back vertebrae about a little higher than the nipple line. The traditional surgical method is open-heart surgery, which takes a long time, has a long incision, is very traumatic, and is extremely risky because of its proximity to important organs of the body such as the heart and lungs and the large blood vessels surrounding them. The current popular surgical method in Europe and America is endoscopic sympathectomy (thoracoscopy), which is the only effective and long-lasting method for treating hand sweating, requiring only 2-3 tiny incisions of about 1 cm in diameter in each side of the armpit, without opening the chest. This surgery is a tiny incision, less painful, less scarring and does not affect the aesthetics. The unilateral procedure only takes about half an hour, and except for a very small number of patients who experience a reactive increase in sweating on the soles of the feet and/armpits, the majority of patients’ excessive hand sweating symptoms disappear immediately after surgery, which can be described as “immediate”. The pain that has been building up for years or decades disappears immediately, and the patient’s self-confidence increases rapidly, enabling him or her to integrate into normal social life, interpersonal communication and work as soon as possible. Psychometric studies have also found significant improvements in the mental health of patients after surgery, with treatment success rates as high as 95-99%. We people are hand in hand, heart to heart, many times our emotions are transmitted through our hands, so we sincerely hope that through our efforts, we can let more friends with hand sweating find hope for their lives and bring more and better future to their lives. Finally, I wish all of our patients and friends a tiger and a higher level of success in the new year.
