When to worry about vaginal odour with bacterial vaginosis

Bacterial vaginosis happens when the usual balance of vaginal bacteria changes. The odour may be stronger after sex or during a period, and discharge can look thin and greyish or white. Itching is not always present. Odour alone cannot confirm the cause because irritation, a retained tampon, and sexually transmitted infections can produce overlapping symptoms. A clinician may ask about discharge, discomfort, sexual health, pregnancy, and recent products or antibiotics, then choose an examination or swab if needed.

Arrange an appointment if the smell does not settle, returns after treatment, or comes with unusual discharge. Take prescribed treatment exactly as directed and avoid sharing leftover medicine. Wash the outside gently with water or a mild, unscented cleanser; do not douche or use scented sprays inside the vagina. Keep the area dry, choose breathable underwear, and pause sex or use condoms if sex worsens irritation until you have advice.

Seek prompt medical care for fever, pelvic or lower-abdominal pain, vomiting, pain during sex, bleeding outside your period, sores, or marked burning when urinating. Contact a maternity service promptly if you are pregnant and notice new odour, discharge, pain, bleeding, or reduced wellbeing. Go to urgent care for severe pain, fainting, confusion, or rapidly worsening symptoms.

You could ask: Could this be bacterial vaginosis or another infection? Do I need a swab or sexual-health test? Which products should I avoid? When should symptoms improve, and what should I do if the odour returns?
