Mostly primary hand sweating caused by sympathetic hyperexcitation, about 0.3% incidence, while its family history is up to 13%. What are the causes of excessive hand sweating? The sweating of the palms is usually different from the sweating of other parts of the body, because if the sweating of other parts of the body is caused by heat, the sweating of the palms is related to the physical condition of each person, endocrine and other such factors. The treatment of hyperhidrosis is divided into medication and surgery. The medication is actually a sympathetic nerve inhibiting drug, which can reduce hand sweating, but it has a short duration of action, usually after a few hours to a day, the drug is metabolized and the hyperhidrosis recurs, so it must be used for a long time. And the body has sympathetic nerves in all organs of the body, so after using a large amount of medication, it will also cause side effects in other organs of the body and other corresponding systemic symptoms. Therefore, the only way to cure hyperhidrosis in the hands is surgery, which involves cutting off part of the thoracic sympathetic nerve. This is to control hand sweating.
