What causes bad vaginal odour?

A mild change around a period or after sex can occur without serious illness. A persistent strong smell, especially with thin discharge, may occur when vaginal bacteria are out of balance. Itching and thick discharge point toward a different pattern, while pelvic pain, fever or pain during sex need assessment for infection.

A forgotten tampon or other retained object can cause a marked unpleasant smell. Hormonal changes, sweat and irritation from scented products can alter the area too. The smell alone cannot establish a diagnosis.

Clean the vulva gently, change out of damp clothing, and avoid douching, perfumed washes and deodorant sprays. Do not try to cover the smell with inserted products. If it continues or returns, arrange an examination so the cause can be identified.

Treatment depends on the finding. Antibiotic Treatment for Pelvic Infection may be used when a clinician diagnoses a bacterial pelvic infection; antibiotics should not be borrowed or saved for later.

Seek prompt advice if odour comes with pelvic pain, fever, unusual discharge, bleeding after sex, sores or pain when passing urine. Contact a clinician promptly during pregnancy. Get urgent help for severe pain, fainting, heavy bleeding or rapidly worsening illness.

What causes fit my symptoms and discharge? Do I need a swab or examination? Could a retained tampon be involved? Which treatment is safe with my medicines or pregnancy plans?
