Hello my name's Adrian Richards, I'm the Director of Aurora Skin Clinics and today I'm going to be talking about Hyperhidrosis which is also know as excessive sweating. So excessive sweating can occur to normal individuals obviously in hot weather or in nervous situations, but Hyperhidrosis is a condition which is characterised by really excessive sweating over and above what is normal and the places you typically get it are the armpits or under arm area, the feet and the soles of the hands. You can get it in other areas such as the small of the back and the face, particularly the hairline of the scalp, but the most common area is really the axilla or underarm area. Now, why do we sweat? Basically there are two types of sweat glands, eccrine sweat glands and Apocrine sweat glands. Eccrine sweat glands produce a thin watery sweat. Apocrine sweat glands produce more thick viscous smelly oily sweat. So the sweat glands we're talking about involving Hyperhidrosis are the eccrine sweat glands which produce the watery non-smelly sweat. So people with Hyperhidrosis have an abnormal innovation to these sweat glands, so in heat, nervous situations, or just for no reason, these sweat glands are turned on. And why are they turned on? I often tell my patients that it's really sort of faulty wiring that the nerve impulses which normally switch the sweat glands on when it's hot when you need to lose weight, heat by evaporation are switched on when they shouldn't be and this really causes excess sweating which can be really very severe. So Hyperhidrosis the severity is classified into four main groups ranging from group 1 which is โ€˜I rarely sweat and never have a problem with it', to 4 which is โ€˜I have a lot of excess sweating and it bothers me on a daily basis'. So, excess sweating normally comes on in teenage years, uncontrollable sweating and makes it very difficult in social situations and often our patients find it very difficult to wear any clothes other than dark clothes, they wear baggy clothes and they find it very difficult to wear sort of light coloured clothes. So Hyperhidrosis is really quite debilitating for a number of people and the really severe Hyperhidrosis will affect 3% to 4% of the population but a greater number are affected with slightly more moderate sweating, and in later videos I'm going to be talking about treatment options for Hyperhidrosis and I hope you'll find what I've said interesting and useful and I would encourage you to view the further videos to get more insight into how the problem can be treated. Thank you.
