Excessive Sweating can be the cause of discomfort and embarrassment. You may have trouble working or enjoying recreational activities because of wet hands or feet or wet stains on clothing.


Unwanted sweat and odour can affect the professional, social, and personal lives of many men and women on a daily basis. Hyperhidrosis is excessive sweating or perspiring above that which is required to regulate body temperature. It can occur in hands, feet, armpits and other areas of the body. Those with hyperhidrosis often feel burdened psychologically, socially and emotionally.
People with hyperhidrosis sweat excessively — above and beyond their physiologic needs. Excessive sweating can occur without warning — even when resting or under cool temperature conditions.
Hyperhidrosis affects a small, but statistically significant, portion of young people globally. It affects their lives and social activities considerably, causing debilitating physical and emotional symptoms.
People living with the disorder suffer social embarrassment at school or work due to excessive sweating. Even simple activities — shaking hands, reading a book, or wearing certain fabrics (i.e. silks and linens) — can cause intense shame.
Experts believe over-stimulation of the sympathetic nerves that trigger the sweat glands of the face, hands, and underarms cause excessive sweating.

Fortunately, there are treatments available to correct unwanted sweating.

Types of hyperhidrosis

Researchers do not understand what causes primary hyperhidrosis. They do believe that lesions on the central nervous system or the presence of other systemic diseases may cause secondary hyperhidrosis.

Primary hyperhidrosis

Involves excessive sweating of the hands, feet, face, or armpits (axillae).
Affects about 3 per cent of the population globally; yet, less than 40 per cent seek help for their condition.
Seems to run in families, indicating a genetic component, but experts have not identified a cause.

Secondary hyperhidrosis

Involves sweating in either one area of the body or all over.
Occurs as a result of an underlying medical condition, such as:

  • Anxiety
  • Stroke
  • Menopause
  • Tuberculosis
  • Acromegaly
  • Cancer
  • Carcinoid syndrome
  • Medications and substance abuse
  • Diabetes
  • Heart disease
  • Lung disease
  • Hyperthyroidism
  • Parkinson’s disease
  • Pheochromocytoma
  • Other infections
