Suffer from excessive sweating? Discover how botulinum toxin can be used to treat hyperhidrosis.

Excessive Sweating

Sweating helps your body control its temperature during exercise and when the environment around you gets hotter. It’s your body’s natural response to an increase in temperature or when you feel anxious. Sweating is regulated by your sympathetic nervous system. In about 1% of the population, this nervous system works at a higher rate, causing sweating to occur at embarrassing times, and in excessive quantities – more than is required to lower your body temperature.

Hyperhidrosis, which literally means “excessive sweating”, can occur in any or multiple areas of your body. It also impacts both sexes equally, and all races.

How can excessive sweating be treated?

Botulinum toxin 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 for hyperhidrosis, with minimal side effects, but top-up treatments are usually required after about six or seven months.

Before any treatment, our experienced and trained prescribers will conduct a full face-to-face assessment and consultation to check your suitability and discuss your various options and risks.
