Because hyperhidrosis persists, early treatment can lead to an early release from the problem. The best time to treat hyperhidrosis of the hands and feet is during adolescence, when the symptoms are most obvious and the nerve development is basically mature. However, if hyperhidrosis is already a problem in elementary school and causes inconvenience, a child over the age of six has no technical difficulties with surgery, but considering the neurodevelopmental problems, surgery during adolescence is still recommended. If you reach the age of forty or later, the surgery often becomes difficult and the failure rate increases due to diseases such as pleural adhesions or lung lesions.
