Excessive Sweating


Hyperhidrosis is the excessive production of sweat. There are many forms of hyperhidrosis and this condition affects a large portion of the general population. Primary focal hyperhidrosis (PFHH) is the most common form of hyperhidrosis and is defined as excessive sweating, not caused by physical activity, that appears symmetrically in a localized fashion. Excessive sweating may have a genetic link, and can appear at any time during a person's life. Excessive sweating often affects the underarms, hands and feet. While excessive sweating doesn't negatively affect an individual's health, many individuals seek treatment because of the impact the condition has on social situations.
