Is sweating a genetic disorder?

Sweating is a natural and healthy function of the body. Excessive sweating may imply the disorder hyperhidrosis, and this is genetically transmitted, as far as is known today. It is quite common, affecting around 2% of the population. It can be triggered by high emotion or by spicy foods. Witness this any time in the Indian restaurant!

Where there is a primary focal hyperhidrosis, the onset is typically at puberty, but some sufferers begin showing signs in primary school. It can be present at birth. The opposite disorder is anihidrosis, where the individual cannot produce sweat at all. Research has discovered that this is caused by a genetic mutation. However, the condition is extremely rare.
