What should you know about body odour?

Fresh sweat is usually not strongly scented. Odour develops when skin bacteria break down substances in sweat, especially in warm, moist areas such as the armpits, groin, and feet. Tight clothing, synthetic fabrics, heavy sweating, skin folds, and damp footwear can make the smell more noticeable. Changes in diet, medicines, hormones, or general health can also alter body scent. A persistent smell is a symptom, not a diagnosis; the pattern and any accompanying skin changes help guide assessment.

Wash the underarms, groin, and feet regularly with a gentle cleanser, then dry carefully between folds and toes. Wear clean, breathable clothing and rotate shoes so they can dry. An antiperspirant reduces sweat reaching the skin, while deodorant mainly masks odour; apply products according to their directions and stop if they irritate you. If ordinary products are not enough, a clinician may discuss Prescription Antiperspirant or Botox For Sweating. Avoid applying fragranced products to cracked or inflamed skin.

Arrange medical assessment if odour appears suddenly, persists despite careful hygiene, or comes with excessive sweating, a rash, sores, pain, fever, weight change, or a new lump. Seek prompt care for a rapidly spreading skin infection, severe illness, confusion, or faintness. A clinician can check for skin infection, medication effects, metabolic problems, or a sweating disorder.

Ask whether the odour pattern suggests a skin condition, whether an antiperspirant is suitable for you, and how to protect sensitive skin. Mention when the change began, where it occurs, and whether sweating or other symptoms changed at the same time.
