Sweating is the body’s means of regulating body temperature, when people are nervous and feel stressed, they naturally sweat more, but if the sweating exceeds the amount needed to regulate body temperature, it is excessive sweating, which is due to the sympathetic nerves of the body are always in a hyperactive state, which is the basis of hand sweating.

Depending on the cause of hand sweating, it can be divided into primary hand sweating and secondary hand sweating. Secondary hand sweating occurs after certain diseases, such as hyperthyroidism, menopausal syndrome, mental disorders, and during certain endocrine treatments. Primary hand sweating is caused by sympathetic hyperactivity and is more common than secondary hand sweating. Treatment of hand sweating can be divided into medical and surgical treatments. It can be treated with internal medications that inhibit hand sweating while also inhibiting sweat gland secretion throughout the body, which has relatively large side effects; it can also be treated with salve immersion, which may be effective but has short-lived effects. Recently, some people have also tried local injection of bacillus toxin (BOTOX), which is only valid for a few months. Therefore, surgery is the only way to eradicate hand sweating, and televised thoracoscopic thoracic sympathectomy is by far the most ideal and safest surgical procedure to treat hand sweating! Hyperhidrosis is basically a physical problem that has no direct impact on health, and the need for surgical treatment depends entirely on the amount of distress caused by hand sweating.
