What should you know about body odour remedy?

Fresh sweat has little smell. Odour develops when bacteria on the skin break down substances in sweat, especially in warm, moist areas such as the underarms, feet, and groin. Hormonal changes, exercise, stress, tight clothing, and some medicines can increase sweating or make odour more noticeable. Persistent odour is not a sign of poor character or poor hygiene, and washing harder can irritate the skin.

Wash odour-prone areas regularly with a gentle cleanser, then dry the folds carefully. Apply antiperspirant to completely dry underarm skin, often in the evening, and follow its label. Change sweaty clothing promptly; choose loose, breathable fabrics and rotate shoes so they can dry. Avoid applying fragranced products to broken or freshly shaved skin. If ordinary antiperspirant does not control heavy sweating, a clinician may discuss a [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) or [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/). See the [Body Odour](/symptoms/body-odour/) guide for symptom context.

Arrange a medical review if the smell is new, unusually strong, present despite consistent care, or accompanied by a rash, pain, sores, fever, unexplained sweating, or a sudden change in sweat pattern. Seek prompt help for severe illness, confusion, or breathing difficulty. A clinician can examine the skin, review medicines and health changes, and decide whether infection, a skin disorder, or excessive sweating needs treatment.

Could a skin infection, medicine, or change in sweating explain this odour? Which antiperspirant should I use, and how should I apply it? Would treatment for excessive sweating be appropriate for the areas affected?
