Hyperhidrosis means excessive sweating which is not related to heat or exercise. It can be localized or generalized (affecting the whole body). It is not a life-threatening condition but it can be embarrassing and cause social anxiety.


The part of the body often affected are palms, soles, armpit, the face and the scalp. This is because these parts of the body have relatively high concentration of sweat glands.


Causes of hyperhidrosis can be broadly classified into- Primary and Secondary.


The primary hyperhidrosis applies when there is no identifiable cause of hyperhidrosis.

Some of the causes of hyperhidrosis in people are: diabetes, reduced blood sugar, thyroid gland problem, anxiety, alcohol abuse, some infections like- HIV, Malaria, Tuberculosis, Some medications like- Propranolol, pilocarpine and some antidepressants.

  • Worrying about having stained clothing
  • Social withdrawal
  • Self-conscious
