For excessive hand sweating (palmar hyperhidrosis), both surgical and non-surgical treatment options are available. Non-surgical treatments include methods such as topically applied Botox injections and iontophoresis, as well as oral medications. These types of non-surgical treatments generally provide temporary relief and may require regular repetitions for sustained efficacy. While not an absolutely definitive cure, Endoscopic Thoracic Sympathectomy (ETS) surgery is considered the most effective treatment method in terms of long-term success rates.
