Medical Dermatology - Excessive Sweating
People with excessive sweating (hyperhidrosis) sweat profusely, and some sweat almost constantly. Although people with a fever or those exposed to very warm environments sweat, people with excessive sweating tend to sweat even without these circumstances. Excessive sweating may affect the entire surface of the skin, but often it is limited to the palms of the hands, soles of the feet, armpits, or genital area.
Usually, no specific cause is found. However, a number of disorders can cause excessive sweating. Excessive sweating can be controlled to some degree with commercial antiperspirants. However, stronger treatment is often needed, especially for the palms, soles, armpits, or genital area.
Severe, chronic wetness can make the affected area white, wrinkled, and cracked. Sometimes the area becomes red and inflamed. The area may emit a foul odor (bromhidrosis) due to the breakdown of sweat by bacteria and yeasts that normally live on the skin. Clothing may also become soaked with sweat.
When excessive underarm sweating gets in the way of your daily activities and antiperspirants haven’t worked, you may be a candidate for BOTOX® treatment.
