Vaginitis

Should I douche to prevent vaginal odor? Gynecologist in Seoul, Korea

The short answer

No. Washing inside the vagina (douching) removes the protective lactobacilli and is a known cause of bacterial vaginosis, which itself causes odor. Wash only the outer vulva with water or a mild, unscented cleanser. A persistent fishy smell needs a test, not stronger washing.

The vagina cleans itself. Its acidic environment, maintained by lactobacilli, keeps harmful bacteria in check. Douching or using internal washes disrupts that balance and makes bacterial vaginosis more likely.

Gentle hygiene

  • Wash the vulva only, with water or a mild unscented product
  • Avoid scented wipes, sprays and bubble baths
  • Wear breathable cotton underwear
  • Change out of wet swimwear or gym clothes promptly

If odor persists, especially a fishy smell after sex or around your period, book a swab test so we can treat the cause.
