Hyperhidrosis affects 2.8% of the population and has severe negative influence on life quality. The disease is represented in many specialties but can unfortunately be incorrectly treated or not treated at all. Primary hyperhidrosis is the most common form. Secondary hyperhidrosis is most often excluded by a few anamnestic data. Botulinum toxin and anticholinergics are adequate treatment options when aluminium chloride is insufficient.
