When does excessive sweating need assessment or treatment?

Quick answer

Sweating that disrupts daily life may be primary hyperhidrosis or related to a condition or medicine. New, night-time or widespread sweating deserves assessment. Treatment ranges from antiperspirants to specialist options selected for the affected area and cause.

Details that help the assessment

Note when sweating began, whether it affects underarms, palms or feet or the whole body, and whether it occurs during sleep. Mention medicines, palpitations, weight loss or fever. Anxiety should not automatically be assumed to explain the symptoms.

Options depend on the site

Antiperspirants reduce sweat, whereas deodorants mainly address odour. A specialist may suggest stronger preparations, iontophoresis for hands or feet, or botulinum toxin injections for selected cases. Medicines can have side effects, so do not borrow another person’s prescription.

What about surgery?

Surgery is considered for certain severe cases after alternatives are assessed, and compensatory sweating elsewhere can occur. Sudden sweating with chest pain or marked dizziness requires urgent medical help rather than being treated as routine chronic hyperhidrosis. Matching treatment to the cause is more useful than simply masking moisture.
