Excessive sweating is a problem many people face and one that can cause extreme embarrassment. Excessive sweating can occur on the palms of the hands, soles of the feet or under the armpits. Although not considered serious the repercussions of having excessive sweating can cause the sufferer to lose confidence and retreat from social situations.
Sweating is normal and necessary for regulating the body temperature in hot weather, during a fever or when you are exercising. With excessive sweating you sweat much more than usual, even when you are not hot, exercising or ill. Sweating can be categorised into three types.
Primary (idiopathic) focal hyperhidrosis is when you sweat normally on the rest of your body but more and usually in symmetry on the hands, soles of the feet, armpits and face. The cause is not known and some people find that their sweat glands in these areas are more overactive than the rest of their body. Sometimes this type of excessive sweating is put down to genetics, and it is quite common, affecting 3 in 100 people. It can come and go at any time and can be triggered by emotion, anxiety, heat or even spicy food.
Secondary focal hyperhidrosis occurs in a focal part of the body and is not symmetrical. Injury or illness may cause this type of excessive sweating to occur.
Finally, generalised hyperhidrosis means that you sweat more than usual all over your body. This is a slightly less common condition. It is normally brought on by an underlying medical condition which can include anxiety disorders, side effects of a particular medicine or hormonal problems.
Injecting Botulinum Toxin can help sufferers of excessive sweating by limiting the glands ability to produce sweat. It can reduce hyperhidrosis by up to 90%. The treatment is minimally invasive and only involves an injection inserted after the area has been numbed. There is very little recovery time and results can be seen in as little as three days. Some patients experience mild redness and bruising directly after the injection but this disappears after a few days. The injection lasts nine months before a repeat injection is required. The procedure is suitable for all areas of the body including the hands.
