What is hyperhidrosis?

Excessive or uncontrollable sweating, also known as hyperhidrosis, can be very distressing and embarrassing, but it's quite common.

Sweating is often involuntary and causes embarrassment to the person sweating excessively. Excessive sweating is hard to get used to and can affect a person's lifestyle, impacting in their quality of life. Excessive sweating not only causes emotional issues but it can cause physical problems. Excessive sweating can cause cold, clammy hands, dehydration, skin infections due to repeated rubbing of the skin in an attempt to remove the excessive sweat.

How does treatment work?

Treatments can help lessen the impact of excessive sweating on your life. Sweating normally happens when the nervous system triggers the sweat glands to produce fluid to cool the body. This can happen in response to the temperature, physical activity or stress.

Sometimes, the nerves become overactive and trigger the sweat glands even without heat or physical activity. This type of hyperhidrosis often runs in families. It can be worse if you are nervous or stressed. Botulinum toxin type A (anti-wrinkle) injections have been found to be effective for hyperhidrosis of the underarms. Botulinum toxin stops the sympathetic nerves (which normally controls sweating) from stimulating the sweat glands, and the effects may last between 4 and 12 months. It is a minimally invasive procedure with fast and effective result.

What areas can be treated?

The most common areas that can be treated are:

  • Underarms

  • Palms

  • Groin

  • Sole of feet

  • Face

What happens during treatment?

Treatment for underarms sweating takes about 20-30 minutes to perform. Other areas of treatment may take shorter or longer to perform. Very fine needles are used to inject and patient generally tolerates treatment very well without anaesthetic.

What can I expect after treatment?

Normal activities can be resumed after treatment. Redness, swelling and bruising can occur and bruises may take up to a week to settle. An improvement to sweating can be seen within 2 weeks. Sometimes, compensatory sweating in other areas could occur post treatment albeit rare. This is usually mild and temporary and will resolves itself.
