Hand sweating is a fairly common form of functional abnormal localized sweating of unknown origin. Because of ethnic specificity, young people growing up in subtropical regions are particularly prone to this problem. The sweat glands are controlled by sympathetic nerves, and hand sweating is caused by unexplained sympathetic overstimulation, such as tension, excitement, stress, or abnormal increases in palm sweating caused by summer heat. Hyperhidrosis: Commonly known as hyperhidrosis of the hands, armpits, feet, and head and face, all of which are caused by excessive sweating of the sweat glands due to sympathetic hyperexcitation. The sympathetic nerve governs sweating throughout the body. Under normal circumstances, the sympathetic nerve regulates body temperature by controlling sweating and heat dissipation. In hyperhidrosis, however, the normal control of sweating is completely lost. There is a genetic predisposition to this disorder in 12% of people. It is a congenital disorder. What are the causes of excessive hand sweating? Sweating of the hands is different from sweating of other parts of the body. Other parts of the body sweat because of heat, and the hotter they get, the more they sweat. Sweaty hands are related to physical fitness, endocrine and so on. A healthy person should have dry palms even if the whole body sweats a lot. And people who have sweaty hands often have no sweat on their bodies, but their palms are full of cold sweat and feel cold. Some people have sweaty hands the more winter they get. Sweaty palms are a sign of a cold body, so if you are also very cold and have cold hands and feet in winter, you should be right. Eat more warm food to regulate your body, but also to strengthen exercise, the purpose is to accelerate blood circulation and promote metabolism, should have a good effect. The symptoms of hand sweating can be clinically graded, for example, the degree of hand sweating lesions are divided into three levels from mild to severe: mild for moist palms; moderate for sweaty palms when wet through a handkerchief; severe for sweaty palms in the form of drops of beads. Hyperhidrosis is mostly considered if most of the following characteristics are met: adolescent onset, family history, bilateral symmetry of excessive sweating, triggering factors such as emotion, exercise, and heat; and no sweating during sleep. The first reason is some systemic diseases, such as thyroid resistance, diabetes and obesity, and some diseases of the central system, which can also cause so much hand sweating, and another main reason is the resistance of the sympathetic nerve that controls hand sweating. The main reason is that the sympathetic nerve, which controls hand sweating, can also cause increased hand sweating. It is advisable to go to the hospital to do a routine blood test, in order to clarify whether there is any infection in the body, and also need to do a chest X-ray to see if there is tuberculosis, because tuberculosis is also the cause of increased hand sweating, and also to do is T3, T4, this is the obvious thyroid function is not normal indicators, and also blood sugar, to see if there is diabetes, through the above-mentioned examination, the use of the The method of exclusion, after this systemic disease causes hand sweating is eliminated, you can be diagnosed with primary hand sweating, you can proceed to the next step of treatment. If it is primary hand sweating, it is caused by sympathetic resistance to the function of the sympathetic nerve innervating the sweat glands. When hand sweating occurs, it is classified as mild, moderate or severe, depending on the degree of sweating. If you want to treat it aggressively, you can have a minimally invasive thymoscopic surgery. So how do you treat hand sweating? The sympathetic nerves that control hand sweating are located in the 2nd and 3rd or T3,4 sections of the thoracic spine, which is approximately on the nipple line, and a little higher up on the sides of the back vertebrae. Bilateral T3 and T4 sympathectomy was performed by TV endoscopy. During the operation, the T3 and T4 sympathetic ganglia are accurately located, a miniature thoracoscope and electrocoagulation hook are placed in the same 10 mm trocar, and the sympathetic chain is electrocautery severed on the surface of the head of the 3rd or 4th rib, and extended laterally along the surface of that rib for 2 to 3 cm to sever any possible collateral pathway nerve fibers. The surgical wound is small, requiring only one to two tiny incisions of less than 1 cm in diameter in each axilla, and no sutures are required. The controversies and sequelae of surgical treatment: Although surgical treatment of hand sweating is indeed effective, after hand sweating stops, it often causes compensatory sweating of varying degrees, and some patients can recover on their own. Compensatory sweating is a condition in which sweating on the upper body (above the nipples) almost stops after surgery, while the lower body is often wet. Except in particularly cold weather, compensatory sweating persists and does not diminish with the passage of time, but may instead increase.
