Hyperhidrosis - Management
How do I diagnose primary focal hyperhidrosis?
- Diagnose primary focal hyperhidrosis when focal, visible, excessive sweating:
- Occurs in at least one of the following sites: axillae, palms, soles, or craniofacial region, and
- Has lasted at least 6 months, and
- Has no apparent cause, and
- Has at least two of the following characteristics:
- Bilateral and relatively symmetrical.
- Impairs daily activities.
- Frequency of at least one episode per week.
- Onset before 25 years of age.
- Positive family history.
- Cessation of local sweating during sleep.
- If symptoms have lasted less than 6 months or onset is at 25 years of age or older, primary focal hyperhidrosis remains a likely diagnosis if other criteria are met, but extra care should be taken to exclude an underlying cause.
- If the presentation is characteristic of primary focal hyperhidrosis and there is no evidence of an underlying cause, no laboratory tests are needed.
