What should you know about body odour solution?

Odour usually comes from bacteria changing sweat and skin oils into stronger-smelling substances. Warmth, moisture, friction, synthetic clothing, and hair can hold these substances against the skin. A change in smell can also follow hormonal shifts, a new medicine, or a skin problem. Body odour alone does not diagnose a serious illness, but a sudden persistent change deserves attention when it comes with other symptoms.

Clean the underarms, feet, and other sweaty areas with a mild cleanser, rinse well, and dry between skin folds. Use antiperspirant on dry skin and wash clothing after heavy sweating. Breathable clothes, fresh socks, and dry footwear can reduce trapped moisture. If sweating is the main driver, ask about a [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/). Selected adults may also discuss [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/) with a qualified clinician. More background is available in [Body Odour](/symptoms/body-odour/).

Book an appointment if self-care has not helped, the odour began suddenly, or you notice redness, scaling, discharge, tenderness, ulcers, or marked sweating at night. A clinician can distinguish ordinary sweat odour from infection or dermatitis and check whether a medicine or health condition is contributing. Do not cover a painful or weeping rash with fragranced deodorant.

Is the odour coming from sweat, irritated skin, or an infection? Should I change my antiperspirant routine? What treatment fits the body areas affected and my medical history?
