Hyperhidrosis is excessive sweating. It can be an embarrassing and serious problem. It can affect social, professional, and intimate relationships.

Hyperhidrosis can be localized. This means it affects a specific part of the body, most commonly the palms of the hands, soles of the feet, or armpits. It can also be generalized, which means it affects the entire body.

Causes 
Hyperhidrosis is divided into two categories: primary and secondary.

Primary has no known cause. If you have primary hyperhidrosis, a sweating attack may be triggered by:

  • Spicy foods
  • Hot climates
  • Certain medications:
    • Fever-lowering medicines
    • Insulin
    • Meperidine
    • Emetics (vomit-inducing medicines)
    • Alcohol
    • Pilocarpine

Secondary is caused by an underlying condition. These include:

  • Menopause 
  • Fever
  • Infection
  • Cancer, such as lymphoma 
  • Thyroid disease
  • Acromegaly or anterior pituitary tumor
  • Hypothalamic disorders
  • Adrenal tumor
  • Parkinson's disease
