Hyperhidrosis is a common condition in which a person sweats excessively.
Commonly affected areas include:
- palms of your hands
- soles of your feet
- face and chest
What is excessive sweating?
For example, you may have hyperhidrosis if:
- you avoid physical contact, such as shaking hands, because you feel self-conscious about your sweating
- you don’t take part in activities, such as dancing or exercise, for fear they will make your sweating worse
- excessive sweating is interfering with your job – for example, you have difficulty holding tools or using a computer keyboard
- you’re having problems with normal daily activities, such as driving
- you’re spending a significant amount of time coping with sweating – for example, frequently showering and changing your clothes
- you become socially withdrawn and self-conscious
Botulinum toxin can be utilised to treat the areas of the body affected by hyperhidrosis. This helps reduce sweating in these areas by blocking the signals from the brain to the sweat glands.
Around 15-20 treatments are given in the affected areas of the body, such as the armpits, hands, feet or face. The procedure usually takes about 30-45 minutes in total.
The effect of the injections usually lasts for several months, after which time the treatment can be repeated if necessary.
