Hand sweating, also known as primary hand sweating, can be considered a narrower sense of hyperhidrosis, a disorder caused by excessive sweat secretion from the sweat glands of the hands, mostly without an obvious organic cause. The primary hand sweat may also be caused by a dysfunction of the sympathetic nervous system. From the treatment, there are generally non-surgical treatment methods and surgical treatment methods. Non-surgical treatment options are topical application of antiperspirant medications, such as a mixture of chlorinated hydrogen and ethanol, which can be used as an antiperspirant. Electrolysis or iontophoresis can also be chosen, as well as acetylcholine receptor blockers for targeted administration, and then there is the option of blocking therapy with botulinum toxin type A. Surgical methods are relatively more effective in the long term, and can be used for more permanent surgical treatment by clamping or blocking the sympathetic nerve chain.
