Hyperhidrosis is a common condition where a person sweats excessively, and much more than the body needs to regulate its temperature.

Excessive sweating doesn't usually pose a serious threat to a person’s health, but it can be embarrassing and distressing. The inconvenience of it can also have a negative impact on your quality of life.

There is no set way of defining excessive sweating, but if sweating is interfering with your daily life and normal activities, you may have hyperhidrosis.

Btx
Btx is a relatively new treatment for people with hyperhidrosis. Btx is a powerful protein that can be used safely in tiny (minute) doses. Around 12 to 20 injections of Btx are given in the affected areas of the body, such as the armpits, hands, feet or face.

The procedure takes about 30 to 45 minutes. It works by blocking the signals from the brain to the sweat glands, reducing the amount of sweat that is produced.

The availability of Btx on the NHS can vary widely depending on the policy of your primary care trust (PCT), and many people can only access the treatment by going to a private clinic. Costs for private treatment depend on which part of the body needs to be treated. For example, injecting the forehead costs around £150 while treating both armpits costs about £400.

The effects of Btx usually last from two to eight months, after which time further treatment will be needed.
