Hyperhydrosis; What is it?
Hyperhydrosis is excessive and profuse perspiration in the underarm area and can cause embarrassing wet marks on shirts. Patients with this condition avoid many colors and fabrics which could show the sweat marks trying to avoid personal ridicule.
Unfortunately, nearly one percent of the population has excessive sweating where the body's sympathetic nervous system overworks to cool down the internal body temperature. This affects the nerve endings and decreases the transmission of nerve impulses to sweat glands, effectively increasing the production of sweat from the sweat glands.
The practice of injection into the area of excessive sweating has been shown to cause temporary benefit in hyperhydrosis patients for up to six months.
