Hand sweating is caused by an abnormal increase in sweating on the palms of the hands due to stress, excitement, pressure, or summer heat. Hand sweating can occur in both men and women and is quite common in young people of Eastern ethnicity (about 3%) and may run in families (about 12.5%). The treatment of hand sweating is divided into medical and surgical therapies; the medical treatment for hand sweating includes oral and topical medications, but their effects are short-lived and have side effects that prevent long-term fundamental treatment; recently, some people have tried topical bacillus toxin (BOTOX), but its effectiveness lasts only a few months. The traditional surgical method is to remove the second and third sympathetic ganglia from both sides by cutting into the center of the back, which takes a long time to operate and recover, and requires hospitalization because of the painful wound of about five to seven centimeters. The patient should be admitted to the hospital on the day of the surgery, and if there is no discomfort after the surgery, the patient can be discharged on the same day, or if the patient has severe chest pain, the patient will be kept in the hospital for one day for observation before being discharged. Hand sweats after surgery will feel a little chest tightness which is normal, both sides of the wound before the stitches are removed do not touch the water, if accidentally wet; immediately replace the sterilized gauze, so that the wound remains dry. Of course, there are some limitations to thoracic endoscopic cautery; for example, people with congenital pulmonary adhesions, or those who have suffered from costochondritis or lung disease, or those who have undergone surgical treatment for hand sweating and have severe adhesions may not be suitable for this method, and should be evaluated by a physician before making a decision. There are children under the age of 12 who have this problem and are brought in by their parents. We believe that hand sweating may cause inconvenience in the learning process, but will not affect academic performance. In addition to the reduction in hand sweating, some patients also have less sweating in their armpits and feet after hand sweating surgery; however, normal people sweat to dissipate heat and lower body temperature, so some degree of sweating is still necessary. For those who wish to undergo surgery, careful consideration should be given before surgery. The chance of improving sweating on the palms of the hands and feet at the same time is about 60-70%. Even if the sweating on the palms of the feet does not improve after surgery, it is not likely to worsen (compensatory sweating on the soles of the feet is a rare occurrence). However, since the cure rate for foot sweating is only 60-70%, this procedure is not recommended for patients who only have foot sweating but not hand sweating. In addition to the compensatory sweating mentioned above, some people may feel that their hands are too dry in winter and need hand cream.
