Normal sweating is a physiological, sensible process in which the body regulates its temperature.
Excessive sweating, for example in the armpit (Latin: hyperhidrosis, German: Hyperhidrose) no longer has any function and is very unpleasant. This ranges from unpleasant odours to runny sweat to constant stains in clothing that are difficult to hide. Problems in social contact with avoidance strategies follow.
