Hyperhidrosis is a medical condition in which a person sweats excessively and unpredictably. People with hyperhidrosis may sweat even when the temperature is cool or when they are at rest.
Sweating - excessive; Perspiration - excessive; Diaphoresis
Sweating helps the body stay cool. In most cases, it is perfectly natural. People sweat more in warm temperatures, when they exercise, or in response to situations that make them nervous, angry, embarrassed, or afraid.
Excessive sweating occurs without such triggers. People with hyperhidrosis appear to have overactive sweat glands. The uncontrollable sweating can lead to significant discomfort, both physical and emotional.
When excessive sweating affects the hands, feet, and armpits, it is called focal hyperhidrosis. In most cases, no cause can be found. It seems to run in families.
Sweating that is not caused by another disease is called primary hyperhidrosis.
If the sweating occurs as a result of another medical condition, it is called secondary hyperhidrosis. The sweating may be all over the body (generalized) or it may be in one area (focal). Conditions that cause secondary hyperhidrosis include:

A wide range of common treatments for hyperhidrosis includes:
