Treatment for Excessive Sweating (Hyperhidrosis)

What is hyperhidrosis?

Hyperhidrosis means excessive sweating. Sweating is one of the most important ways in which the body loses heat; however people with hyperhidrosis produce sweat in amounts far greater than needed to control their temperature.

There are 2 main types of hyperhidrosis:

  1. Focal hyperhidrosis is the most common type involving excessive sweating on the feet, hands and in about 30-40% of cases, the armpits. The face may also be affected, but less often. Botox is indicated for the treatment of focal hyperhidrosis affecting the armpits (axillary) when other treatments have not worked.
  2. Generalised hyperhidrosis affects the whole body. It is much less common and is usually caused by another illness such as infection, diabetes or overactivity of the thyroid gland. The sweating usually stops when the illness is treated

What causes hyperhidrosis?

It is not known why some people are affected and others are not but there may be a genetic element. Hyperhidrosis is caused by overactivity of one type of sweat gland, the eccrine gland. These glands are found all over the body but are particularly concentrated on the palms of the hands, the soles of the feet and in the armpits.
Many things can trigger sweating and this is true for hyperhidrosis-it is just the amount that varies.

Examples of triggers include

  • exercise
  • heat or cold
  • alcohol, coffee or tea, smoking, hot or spicy food
  • stress ,anxiety or strong emotions

Self-help measures include choosing cool clothing, keep environment cool and well aired, avoid drinks that trigger sweating and  reduce stress and tension.

What happens during a Botox treatment?

Using a very fine needle the doctor will inject a small amount of a dilute solution of Botox into 10-15 places in the armpit on the skin. This would take 20-30 minutes. The changes should be noticeable after about a week sometimes less. In a clinical trial, sweat production was reduced by 83% after 1 week. The affects wear off in 5-7 months in most people. Re-treatment is then required if wanted.
