Hyperhidrosis is excessive sweating. It can be an embarrassing and serious problem. It can affect social, professional, and intimate relationships.

The sweating may be in just one area. It is most common in the palms of the hands, soles of the feet, and/or armpits. In some cases the sweating can also affect the entire body. Hyperhidrosis is divided into two categories:

  • Primary hyperhidrosis
    • usually affects specific areas
    • has no known cause
  • Secondary hyperhidrosis
    • usually the entire body
    • caused by an underlying condition
