Excess sweating is medically known as hyperhidrosis and is often an embarrassing condition, causing you to sweat much more than your body needs to in order to regulate its temperature. It is fairly common in the UK, with roughly one million people having this condition.
The most commonly affected area is the underarms. However, excessive sweating may be also present in many parts of your body, including hands, feet, face and head. Sweating is generally harmless and happens to both men and women.
