Hyperhidrosis is abnormal excessive sweating that is out of proportion with temperature control. It is well documented that it can cause social and psychological embarrassment due to the visual appearance of sweat patches on clothes, obvious odours and general discomfort.

The most common places for this problem are armpits, hands, and feet. Although there are some medical therapies to help with this condition, they are not always fully effective. Botulinum toxin (Botox) provides a reliable, medium-to-long term improvement in symptoms and has been recommended by the NHS. Unfortunately, most areas of the U.K. will not have available NHS funding for this procedure.
