An excessive production of perspiration is relatively common and results in superfluous perspiration in the armpits, on the palms of the hands and on the feet. There are several methods to prevent excessive perspiration. The first method of injecting Botolinumtoxin (Botox / Dysport) into the affected areas achieves good results, completely without an operation. The medicament is injected under the skin. There it blocks the nerve fibres that are responsible for producing sweat. The effect is apparent after 4-8 days and lasts about 4-6 months, but then subsides. Regular repetition is an expensive course of treatment. However, one has a 100 percent effect and no formation of perspiration / sweat patches under the arms. There are no known side effects.
A further possibility is the suction curettage of the axial sweat glands. Similar to liposuction, the sweat glands are "abraded" with fine cannulas under the skin using a local anaesthetic. During this procedure all the sweat glands are never removed. Perspiration can only be reduced by 80%. So some function still remains and a "normal" amount of perspiration during physical exertion and in heat. In a few cases only a repeat operation can lead to a perfect result. The operation is relatively low in risk. It is not suitable for the palms of the hands or for the feet.
In addition, there is the method of severance of the nerves at the nerve plexus on the spine which alleviates perspiration on the palms of the hands. This operation is very complex and has to be carried out by a thorax surgeon (e.g. in the Berlin Charité).
