What should you know about body odour bacteria?

Fresh sweat is often not strongly scented. Odour can appear as bacteria on the skin process compounds from sweat, skin oils, and shed cells. Underarms, feet, the groin, and skin folds can hold heat and moisture, creating conditions that support this process. Hair, tight clothing, and trapped moisture may make the smell more noticeable. Odour is not proof of poor hygiene, and washing too aggressively can irritate skin without solving the cause.

Wash affected areas gently, dry them carefully, and change sweaty clothing promptly. Breathable fabrics and clean socks can reduce moisture around the feet. A deodorant masks or reduces odour, while an antiperspirant reduces sweat reaching the skin; apply products only as directed and stop if burning or a rash develops. If sweating is a major trigger, a clinician can discuss prescription antiperspirant or treatments such as Botox For Sweating.

Arrange an assessment if odour changes suddenly, persists despite careful washing and clothing changes, or comes with a rash, pain, sores, fever, night sweats, or a marked increase in sweating. A clinician can examine the skin and review medicines, hormones, and health conditions that may contribute. Seek prompt care for spreading redness, severe tenderness, or pus.

Could a skin infection, medication, or increased sweating be contributing? Which product is suitable for my skin? Should I use a prescription antiperspirant, and what signs would mean I should stop it?
