Hyperhidrosis is a common condition where a person sweats excessively, and much more than the body needs in order 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.
Many people with the condition are too embarrassed to seek medical help or believe that nothing can be done to improve their symptoms. However, there is help available. Botulinum toxin is a purified protein that can be used effectively in small doses. Around 12 to 20 injections of botulinum toxin 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. The protein works by blocking the signals from the brain to the sweat glands, reducing the amount of sweat that is produced. The effect usually lasts from two to eight months, after which time further treatment will be needed.
