Excessive Sweating/ Hyperhidrosis


Sweating is necessary to control body temperature during times of exercise and in warm/hot surroundings, and is a normal response to a rise in temperature or anxiety. Sweating is regulated by the sympathetic nervous system. In about 1% of the population, this system is revved-up and works at a very high level, causing sweating to occur at inappropriate times, far in excess of the amount necessary to maintain normal body temperature. It can occur in many different areas of the body, and the condition is known as Hyperhidrosis, which means 'excessive sweating'. It affects both sexes equally, and all races.

What is it & How does it Work?

Botulinum toxin, often referred to as Botox® is a naturally occurring protein produced by the bacterium Clostridium Botulinum. The toxin blocks the transition of chemical messages sent from the nerve to cause the muscle to contract.

Botulinum toxin is injected into the affected area, and works by blocking the nerves that supply the sweat glands, stopping them from producing sweat.

Botulinum toxin injections work well as a safe and effective treatment, with minimal side effects, but top-up treatments are usually required after about six or seven months and it is not easily available on the NHS. Before seeking treatment with botulinum toxin, make sure you have had a proper diagnosis from your GP and perhaps tried other options available on The NHS.

Common areas for treatment include:

• Under arms

• Hands

• Feet

• Chest

• Groin

• Facial areas
