Hyperhidrosis (hi-pur-hi-DROE-sis) is excessive sweating that occurs even when the temperature isn't hot and you're not exercising. In some people who have hyperhidrosis, the sweat literally drips off their hands.
Hyperhidrosis usually affects the palms of the hands, soles of the feet and underarms. Besides disrupting normal daily activities, hyperhidrosis can cause social anxiety or embarrassment.
One of the first options for treatment involves using prescription-strength antiperspirants on the affected areas. In severe cases, your doctor may suggest surgery either to remove the sweat glands or to disconnect the nerves responsible for the overproduction of sweat.
