What causes body odour in females?

Sweat itself has little smell. Odour develops as bacteria break down sweat and other substances on areas such as the underarms, groin, feet, and skin folds. Puberty, menstrual-cycle changes, pregnancy, and menopause may change sweating or skin conditions. Tight clothing, trapped moisture, shaving irritation, and bacterial or fungal overgrowth can add to the problem.

A sudden change can also follow a new medicine, diet, or health condition. The quality of the smell is not enough to identify a diagnosis, so associated symptoms and examination matter.

Wash affected areas gently, dry skin folds carefully, change damp clothing, and choose breathable fabrics. An antiperspirant reduces sweat; deodorant mainly masks odour. Apply products to dry, intact skin and stop if burning or a rash develops. If ordinary measures fail, a clinician can assess the skin and discuss Prescription Antiperspirant or Botox For Sweating when excessive sweating is contributing.

Book an assessment if odour persists despite careful washing, begins suddenly without an obvious trigger, or comes with a rash, pain, discharge, fever, night sweats, marked thirst, or unexplained weight change. Seek urgent help for severe illness, confusion, breathing difficulty, or a rapidly spreading painful skin infection. Do not use strong antiseptics or fragranced products inside the vagina.

Ask whether sweating, a skin infection, hormonal change, medicine, or another condition could explain the change; whether testing is needed; and which antiperspirant is appropriate for sensitive skin.
