Definition of Hyperhidrosis

Hyperhidrosis is a disorder which makes people sweat more than necessary.

In most cases, the cause of Hyperhidrosis is unknown. This is known as primary Hyperhidrosis. Hyperhidrosis can also be caused by an underlying condition (e.g. endocrine disorders, menopause, obesity, nerve damage), and by some drugs, although this is very uncommon. This is known as secondary hyperhidrosis.

When sweating occurs over the entire body, it is known as generalized hyperhidrosis.

When sweating occurs in certain places only, it is known as focal hyperhidrosis. Most often, focal hyperhidrosis affects:

  • Underarms (axillary hyperhidrosis)
  • Hands (palmar hyperhidrosis)
  • Feet (plantar hyperhidrosis)
  • Face (facial hyperhidrosis)


Without proper treatment, hyperhidrosis can have a great impact on the quality of life. Sweating hands, underarms, feet or face can give the wrong impression in business and personal situations. For example, it may seem that the person with hyperhidrosis is nervous or ill, when this is not the case.

Excessive sweating can also be inconvenient. People with hyperhidrosis may have to wash more often, have clothes cleaned more often, and even use special pads to absorb excess perspiration.

Finally, excess sweating can damage the skin, promote infection and cause unpleasant odours. These outcomes are undesirable from both the medical and the social point of view.

Hyperhidrosis, while not a dangerous disorder, is unpleasant and inconvenient. Fortunately, doctors are now learning much more about this condition and how to manage it.

Many of these treatments are covered by medical plans and Dr. Tomi can also discuss this further with you at your consultation visit.

Focal Injections

Focal hyperhidrosis can be treated with Botox Cosmetic®. This treatment is approved in Canada for patients with axillary hyperhidrosis – in other words, hyperhidrosis localized in the underarms.

Treatment consists of a series of tiny injections of Botox Cosmetic®. These injections block the neurochemical activity of the nerves which cause the excessive sweating. Blocking these nerve impulses reduces sweating. In one study, it was showed that sweat production was decreased after one week.

Getting Hyperhidrosis Under Control

If you suffer from hyperhidrosis, you may find the disorder is having an impact on your quality of life.

Now you can do something about it. Talk to your doctor about how to reduce excess sweating with minimum risk or discomfort. Many people with hyperhidrosis have used therapies to manage their condition. You can do the same.
