The causes of hyperhidrosis are generally divided into two main categories, the majority of which are primary and only a very small number of which are secondary. Primary hyperhidrosis means that there is no specific cause, just as some people are taller and some are shorter, so the amount of sweating varies from person to person. The sympathetic nervous system of people with hand sweating is more responsive than others, and the sympathetic nervous system controls the secretion of our sweat glands and the contraction of blood vessels, so when we are nervous, even in a hot environment, we sweat much more than the average person, and the underlying cause is not yet known. Secondary hand sweating occurs after certain diseases, such as hyperthyroidism, menopausal syndrome, mental disorders, etc. Increased hand sweating can also occur when certain endocrine treatments are done. Primary hand sweating is a little more common than secondary hand sweating. However, experts also say that hand sweating was not considered a disease in the past, and many people were often blind to it. Nowadays, people’s demands on their lives have started to improve, and they are paying a lot of attention to the way they behave in social situations, so more and more people are going to the hospital. After all, it can be troublesome to cause unnecessary misunderstanding to the unknown other party. The actual hand sweat itself is caused by the hyperactive sympathetic nervous system, and the treatment must be directed at the sympathetic nervous system. The traditional treatment methods include oral medication, local treatment, open back sympathectomy and percutaneous sympathetic cautery, but most of them are gradually abandoned because the prognosis of the surgery is not very good or the surgical trauma is too large. Currently, the most recognized and effective is the televised thoracoscopic thoracic sympathectomy. In this method, an incision of about 2 cm is made in each axilla, and the thoracic sympathetic nerve that causes hand sweating is cut accurately and quickly under the precise guidance of the thoracoscope and using a television monitoring system. The results are immediate and the incisions are small and hidden, with very few recurrences. However, any surgery has varying degrees of risk and a certain percentage of complications. Possible complications of TV thoracoscopic thoracic sympathectomy include hemothorax due to chest bleeding or pneumothorax due to ruptured lung membranes and alveoli, but the incidence of these complications is less than one percent. Surgical treatment is relatively risky and requires high professional requirements for doctors, but it is also the most effective method. Experts believe that as long as you choose a regular hospital and a professional doctor to perform the surgery, the risks can still be largely avoided and you should not worry too much. The actual fact is that you will find a lot of people who have been in the business for a long time. As for the advertisements published in some newspapers to cure sweating and fox odor, it is definitely a scam that takes advantage of human weaknesses. Second, how much does it cost to treat hand sweating The thoracic sympathetic neurectomy requires hospitalization after surgery, which takes about 3-4 days and costs about 7000. Third, the best time to treat hand sweating The best time to treat hand sweating is during adolescence, when the symptoms are most obvious. The symptoms of sweaty palms can be lifted immediately after surgery, and the success rate of surgery is high. If you reach the age of 40 or later, the surgery often becomes difficult and the failure rate increases due to diseases such as pleural adhesions or lung lesions. Early is also not the better. Small children who are not yet physiologically mature are also not suitable for surgical treatment. Since the child’s growth and development has not yet stopped, and because there is not much pressure to go to school, the hand sweating condition should not be enough to cause problems in life.
