Excessive sweating, also known as hyperhidrosis, is a common disorder that affects many people. Although a variety of areas can be involved, typically people with hyperhidrosis suffer from excessive underarm, foot and/or hand sweating.
 
The cause of this condition is unknown although it often runs in families and begins during childhood. Once topical treatments have failed, treatment with Botox injections can help relieve the symptoms of hyperhidrosis by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. When the sweat glands don’t receive chemical signals, the excessive sweating stops. Botox™ injections for hyperhidrosis are safe, and they usually stop the production of excessive sweat for 4-6 months.
