Hyperhidrosis is a medical condition in which a person exhibits excessive sweating, [1] [2] more than is required for the regulation of body temperature. [3] Although it is primarily a physical burden, hyperhidrosis can deteriorate the quality of life of the people who are affected from a psychological, emotional, and social perspective. [4]
The sweating is induced to reduce body heat. Excessive sweating due to nervousness, anger, previous trauma or fear is called hyperhidrosis. Compensatory hyperhidrosis is the most common side effect of endoscopic thoracic sympathectomy, a surgery to treat severe focal hyperhidrosis, often affecting just one part of the body.

Focal hyperhidrosis, also known as primary hyperhidrosis, is a disease characterized by an excessive sweating localized in certain body regions (particularly palms, feet and underarms). Studies suggest that this condition, affecting between 1% and 3% of the US population, seems to have a genetic predisposition in about two thirds of those affected.
Heat stroke is defined by two key features: a core body temperature above 40 °C (104 °F) and central nervous system dysfunction. In classic heat stroke, sweating ceases due to sweat gland dysfunction or depletion. This loss of evaporative cooling further accelerates heat accumulation.
Palmoplantar hyperhidrosis is excessive sweating localized to the palms of the hands and soles of the feet. It is a form of focal hyperhidrosis in that the excessive sweating is limited to a specific region of the body. As with other types of focal hyperhidrosis (e.g. axillary and craniofacial) the sweating tends to worsen during warm weather. [1]
