Hyperhidrosis is an increased tendency to sweat, often following the slightest exertion. The underarms are affected most often, with the palms of the hands, soles of the feet, head or in rare cases the whole body, being affected less frequently. The underlying cause of the complaint is a slightly defective regulation of the autonomic (unconscious) nervous system. Sweat patches on our clothes and having sweaty palms carry a great social stigma in our society.
Those affected are often ashamed, lose confidence and can stop playing sport or avoid having a social life. The psychological impairment can be quite alarming; often having dry hands or underarms can be among the greatest wishes of those affected. Nowadays, treating localised hyperhidrosis no longer presents any great difficulty, although due to possible significant side-effects, we do not recommend surgical treatment methods.
In cases where surface treatment does not produce satisfactory results, we use botulinum toxin. Botulinum toxin is injected under the skin’s surface into the areas of increased perspiration using a very fine needle. The substance decouples the sweat glands from the autonomic nervous system, which results in the production of sweat coming to a complete stop in just a few days (or less often almost completely). In most cases this treatment, which is practically free of side-effects, should be carried out around twice a year.
