Hyperhidrosis: Sweating is a natural body function needed for the regulation of body temperature. There are five million sweat glands throughout the body and about two-thirds of these glands are situated in the hands. The secretion of sweat is controlled by the sympathetic or (vegetative) nervous system. In approximately 1% of the population, the nerves are over-stimulated and sweat is produced far greater than needed to keep a constant Temperature. This condition is referred to as Hyperhidrosis. Excessive sweating may be episodic or continuous. Profuse sweating may be caused by warm weather, emotional stress, or for no reason at all. The hands, feet and armpits are the most common locations. The condition usually starts during adolescence and is lifelong.
Axillary hyperhidrosis (sweating of the armpits) that does not respond to topical antiperspirants may be treated with Botox®. When injected into areas of the skin that produce excess sweat, effectively reduces sweat production for many months. Botox®™ injections to the sweat-producing areas of the armpits can frequently provide relief for as long as 6 months. Botox®™ injections are also an effective remedy for palmar hyperhidrosis (sweating of the palms of the hands) and relief can last many months. However, the pain involved in the administration of Botox® to the hands along with occasional problems related to muscle weakness can make Botox®™ a less desirable form of therapy for treating palmar hyperhidrosis.
