Sweating is a “small exercise” that the body does every day. The actual sweat is a way for our body to automatically dissipate heat and cool down in the hot weather. The 25-year-old girl, Zhang still (a pseudonym), has been plagued by sweaty hands for years. The constant sweating of her palms not only affected her mood at work, but also made her cautious in interpersonal interactions. The first hospital in Hangzhou, deputy director of thoracic surgery Feng Xing, Zhang still has hand sweating. The sympathetic nerves that dominate the sweat glands are overexcited and are an important cause of hand sweating. This disease is not a major health problem, but it can bring great embarrassment and distress to life, work and social life. The hand sweat makes her “sweat” Zhang still in Taizhou, Zhejiang Province, is engaged in education, but she is often distressed by the hands that are wet all year round. Each time to students to correct homework, marking test papers, have to pad a thick stack of paper towels. When she met colleagues and parents, she did not dare to shake hands easily, and those who had met her, called her “sailor” figuratively. ”Not just typing at work, correcting homework, even sometimes holding hands with her boyfriend, but also feel their hands very wet and sticky.” Zhang still said, “In order to solve the trouble, when I was in college I went around to seek medical help, once for two consecutive summers have been taking Chinese medicine, hand sweating once there are signs of relief. But wait until after work, the medicine did not continue to eat, the feeling of hand sweat is more obvious.” ”At work, every time I need to shake hands, my heart is very apprehensive, feel their palms of sweat, certainly make each other uncomfortable.” Zhang still said that the winter when it was cold was fine, in recent days, as the weather gradually hot, her hands and feet are involuntarily sweating, which once again put her in pain. After hearing Zhang’s story, Dr. Feng Xing, deputy chief of thoracic surgery, diagnosed her with severe hand sweating. “The reason for this is that it’s a common, unexplained, functional localized abnormal sweating, and because of its ethnic specificity, young people who grow up in subtropical areas are particularly prone to it.” The secretion of the sweat glands is controlled by the sympathetic nerve, which normally regulates the body’s temperature by controlling sweating and heat dissipation. The sweating of patients with hand sweating is completely out of normal control. The abnormal increase in palm sweating is caused by unexplained sympathetic overstimulation, such as tension, excitement, stress or summer heat.” Dr. Feng Xing, deputy chief physician, introduced that patients with hand sweating disorder are healthy and normal except for sweaty hands. These people are prone to sweaty, wet and cold palms whether it’s a hot summer or a cold day, and some people even sweat on the soles of their feet and armpits together, and sweat in the form of droplets in summer, so it’s also known as hyperhidrosis. ”Hand sweating is a congenital disorder. A survey once showed that there is about 0.3% incidence in youths between the ages of 10 and 30, which means that about one in 3,000 youths suffers from fairly pronounced excessive sweating of the palms, both men and women, while its family heritability is as high as 13%.” Feng Xing, deputy chief physician, said, “Most patients have had excessive palm sweating since childhood, and it becomes more severe in adolescence.” Hand sweating can be treated from the chest After doing an examination, Zhang still decided to undergo a minimally invasive needle thoracoscopic surgery. The surgery was completed in more than twenty minutes by taking only two 5mm small openings in both chest walls and axillae and using an electric knife to cut the T4 sympathetic nerves that innervate the palm sweat glands in the bilateral chest cavity. After waking up from anesthesia, Xiao Zhang immediately felt the sweaty hands disappear, and she couldn’t hide her excitement: “The hand sweat that has accompanied me for more than 20 years is finally gone, and I am no longer a ‘sailor’.” The primary hand sweat, although not a major health concern, but sweat dripping more than, can be a long-term problem for patients, and even cause psychological disorders. Feng Xing, deputy chief physician, said that some patients are afraid of surgery, mainly because they are afraid of pain, which can actually be completely eradicated through minimally invasive surgery. ”Now the only lasting and effective treatment for primary hand sweating is thoracic sympathetic nerve chain amputation. However, secondary hand sweating is caused by tuberculosis, hyperthyroidism, endocrine disorders, psychiatric disorders, and other causes of hand sweating such as endocrine imbalance during menopause, and this condition is also a minority of hand sweating disorders. In these cases, the disease itself must be treated for its etiology and is not a candidate for sympathetic surgery.”
