Is hyperhidrosis serious?

ANSWER

If it's in a specific area, or "focal hyperhidrosis," it's not medically serious. But if you have it all over your body, you should see a doctor as soon as possible. Sweating all over the body at once is called generalized hyperhidrosis. It's often caused by diseases that affect the whole body. Infections, hormone problems, cancer, or nerve problems can be responsible. It often happens during sleep, unlike focal hyperhidrosis, which occurs only when awake.
