When Should You See a Doctor About Body Odour?

Odour develops when sweat or other moisture mixes with substances on the skin. A clinician will consider where it occurs, how sweating has changed, and whether there is rash, soreness, scaling, or pits on the feet. Bromhidrosis can cause persistent strong odour, while erythrasma may affect skin folds with a discoloured rash. Pitted keratolysis can produce odour from the soles alongside small surface depressions.

Odour alone does not identify one condition. The history and skin examination help separate a local skin problem from changes in sweating, hygiene products, clothing, or general health.

Wash gently, dry skin folds and between the toes thoroughly, change damp clothing, and choose breathable fabrics. Use an ordinary antiperspirant as directed if your skin tolerates it, but stop products that sting or cause a rash. Note the sites, timing, triggers, new medicines, and whether anyone else has developed similar symptoms.

Avoid masking a persistent change with repeated fragrance, which can irritate already inflamed skin. See [Body Odour](/symptoms/body-odour/) and [Bromhidrosis](/conditions/bromhidrosis/) for related explanations.

Arrange prompt assessment for odour with spreading redness, warmth, pain, drainage, open skin, or a rapidly worsening rash. Seek urgent help if a sudden body-odour change occurs with severe illness, confusion, breathing difficulty, or faintness. Foot odour with tender cracks or spreading infection also needs timely attention.

Ask whether the smell is linked to sweating, a skin-fold infection, or a foot condition; whether any testing is needed; and how to use treatment without irritating the skin. If sweating is the main problem, ask whether prescription antiperspirant or botulinum toxin treatment is appropriate for the affected area.
