Some people’s palms are wet most of the time, and even shake hands with others have a psychological barrier; some children because of excessive hand sweat, the exam questions did not answer, but the examination paper wet a large area; what exactly is the cause of this? This reporter interviewed Xie Yuancai, chief physician of thoracic surgery at Peking University Shenzhen Hospital. He introduced, excessive hand sweating is actually a disease, medically known as “hand sweating”, although not a serious disease, but excessive sweating makes the patient daily in helplessness, anxiety or panic, to the patient’s work, social and life brings great inconvenience, seriously affect the patient’s self-confidence. 1, excessive hand sweating mistakenly see dermatology Many people want to solve the problem of excessive hand sweating, to the hospital but do not know which department to seek medical attention, dermatology, or internal medicine? The actual fact is that you will find a lot of people who are not able to get a good deal on this. Xie Yuancai introduced that it is indeed difficult for the general public to associate excessive hand sweating with thoracic surgery, thinking that if you sweat a lot you should go to the dermatology department. In fact, excessive hand sweating is due to the imbalance between the sympathetic and parasympathetic nerves. The sympathetic nerve will sweat when it is excited, and the parasympathetic nerve will collect some sweat when it is excited. In normal people, the two nerves will be in balance, and they will be able to dissipate heat by sweating and not make too much sweat. In patients with hand sweating disorder, however, the sympathetic nerve is overexcited, and sweating occurs. It is not entirely clear what causes hand sweating, but it is related to genetic factors. Because of ethnic specificity, young people who grow up in subtropical areas are especially prone to this problem. Shenzhen is a city of young people, so the incidence is relatively high, and many primary and secondary school students have also become a group plagued by hand sweating. 2, emotional tension will aggravate the condition In the opinion of outsiders, sweating more, is not a big problem, but hand sweat patients, but has a common people difficult to understand the pain. Xie Yuancai introduced, tension, excitement, stress or summer heat, etc., will aggravate the symptoms of hand sweating, some patients sweat like dripping water. Some of the hand sweating is secondary to complications caused by hyperthyroidism, diabetes, cardiovascular disease, tumors, etc.; the other is primary, and the general talk about treatment is for primary hand sweating. Because the effect of drugs is not obvious, at present, the problem is basically solved by surgery, that is, to clearly locate a certain location of the sympathetic nerve, and then cut it off, just like a telephone line, directly cut off, the signal will not be passed down. Compared to other hyperhidrosis, hand sweating is easier to solve because the surgical location is already very clear. Many people think that hand sweating is a minor disease and often delay or leave it untreated. Xie Yuancai said that although hand sweating itself will not be aggravated by delay, the symptoms will become more and more pronounced because of the patient’s nervousness. At present, people have less knowledge about this disease, and there is still a need for medical knowledge.
