About Hyperhidrosis

Botulinum toxin injections can effectively treat localized hyperhidrosis by blocking the smooth muscle activity of the sweat glands.

  • Hyperhidrosis is the excessive production of sweat.
  • The production and excretion of sweat are mediated by the sympathetic nervous system and regulated by a gland in our brain called hypothalamus.
  • Sweating plays an important role in the regulation of body temperature.
  • Sweat glands produce an odourless liquid which, when decomposed by the action of bacteria, acquires a characteristic, unpleasant smell.
  • Hyperhidrosis can either be generalized or localized to specific parts of the body. Hands, feet, axillae (i.e. armpits), face, and the groin area are among the most active regions of perspiration due to the relatively high concentration of sweat glands; however, any part of the body may be affected.
  • Primary hyperhidrosis usually starts around puberty and peaks in adulthood. Studies show that there is a genetic component predisposing to the condition. Primary hyperhidrosis is estimated at around 1% of the population, afflicting men and women equally.
  • Primary hyperhidrosis is caused by an exaggerated response to increased body temperature (hot weather, exercise, fever) or emotion.
  • Secondary hyperhidrosis may be secondary to a variety of medical conditions such as thyroid problems, hormone imbalance, diabetes, obesity, certain drugs, etc.
  • Botulinum toxin injections can effectively treat localized hyperhidrosis by blocking the smooth muscle activity of the sweat glands. Results can last up to nine months.
