Primary hyperhidrosis refers to excessive sweating of the palms of the hands, feet or armpits without being caused by any known underlying disease. It is due to increased activity in a part of our nervous system (the sympathetic nervous system). This sympathetic system physically runs like a fibrous cord inside the chest, as if it were a motorway carrying information, and is called the sympathetic chain.

Normally, patients affected by this condition suffer social limitations, as they experience situations such as not being able to write on paper, type, shake hands or caress, use tools or musical instruments, etc. These situations can lead to insecurities when entering the workplace or in personal relationships.

There are different options for the treatment of primary hyperhidrosis, such as topical antiperspirants, systemic medications, iontophoresis or the application of botulinum toxin, as non-invasive alternatives. Generally, patients with profuse sweating do not usually find relief with these alternatives.
