Underarm Sweating (Hyperhydrosis)
Causes, Symptoms and Treatment
Excessive sweating forces men and women to change their clothes every few hours and can really affect their confidence. Hyperhidrosis is a really common disorder, which produces a lot of unhappiness.
Although neurologic, metabolic, and other systemic disease can sometimes cause excessive sweating, most cases occur in people who are otherwise healthy. Heat and emotions may trigger hyperhidrosis in some, but many who suffer from hyperhidrosis sweat nearly all the time regardless of mood or weather.
Botulinum toxin works by blocking the chemical at the end of the nerves so that it cannot work on the glands or muscles. In this case of the sweat glands it turns them off to reduce sweating.
The treatment involves multiple small injections of the toxin a few centimetres apart in the armpit. Patients can expect to see small changes within a couple of days and a noticeable difference within two weeks. As each body reacts differently to the treatment, the length of your results may vary but typically the effect can last three to six months.
Common short term side effects include mild bruising or discomfort at the injection site.
