What should you know about eliminating body odour?

Fresh sweat is usually not strongly scented. Odour develops when bacteria on warm, moist areas such as the underarms, groin, or feet interact with sweat and skin oils. Hormonal changes, stress, exercise, tight clothing, and some medicines can alter sweating or the smell. A new or unusually strong odour can also occur with a skin infection or another health problem, so persistent change should not be dismissed as poor hygiene.

Wash odour-prone areas regularly, dry them carefully, change damp clothes, and choose breathable fabrics. An antiperspirant reduces sweat reaching the skin, while deodorant mainly masks odour; apply an antiperspirant to dry skin as directed. If ordinary products are not enough, a clinician may recommend [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/). When excessive sweating drives the problem, [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/) may be discussed after assessment. Avoid applying fragranced products to irritated or broken skin.

Book an appointment if odour persists despite careful washing and sweat control, starts suddenly, comes from one small area, or occurs with rash, pain, discharge, fever, night sweating, or unexplained weight change. Seek urgent help for severe skin redness with fever or rapidly spreading swelling. A clinician can examine the skin and review medicines, sweating patterns, and other symptoms rather than assuming the cause.

Ask whether your pattern fits [Body Odour](/symptoms/body-odour/), whether infection or a medicine could contribute, and which product is suitable for sensitive skin. Ask how long to try each measure and what signs would warrant review.
