how many people have hyperhidrosis
Hyperhidrosis, or excessive sweating, is a common disorder that produces a lot of unhappiness. An estimated 2%-3% of Americans suffer from excessive sweating of the underarms (axillary hyperhidrosis) or of the palms and soles of the feet (palmoplantar hyperhidrosis). Underarm problems tend to start around puberty, while palm and sole sweating may begin earlier, often during childhood.
