Question: why are my palms sweaty all of a sudden?
Answer: Most people who get sweaty palms a lot don't have a health problem. But there is a medical condition called hyperhidrosis (pronounced: hye-pur-hye-DROE-sis) that can cause a person's palms, feet, armpits, and other parts of the body to sweat heavily. Hyperhidrosis usually begins around puberty.
