The condition in human beings that causes excessive sweating is called hyperhidrosis. This condition can be limited to certain areas of the body like the hands and feet, or show up all over the body. Many people find this condition to be quite upsetting and socially isolating, causing them to become withdrawn from their day-to-day lives. Luckily, Botox® is an excellent solution for treating symptoms of hyperhidrosis. The botulinum toxin in Botox® injections works to block the nerve signals that cause sweating. As these nerve signals become inhibited, it stops the sweat glands in the body from producing too much sweat. The nerves in these areas regenerate every few months, which is why frequent touch-up treatments are required to tackle the problem effectively. Once the patient has undergone enough treatments, they can go on for several months to a year without the need for re-treatments.
