Bacterial vaginosis (BV) is largely about balance: anything that protects your natural vaginal bacteria and avoids irritation can lower your risk of getting BV or having it come back.

What BV Is (Quick context)

BV happens when the “good” Lactobacillus bacteria drop and other bacteria overgrow, which changes the vaginal pH and often causes a thin gray‑white discharge with a fishy smell. It’s not technically an STI, but sex and partner patterns strongly influence your risk.

Everyday Hygiene Habits That Help

Think “gentle, simple, breathable” as your daily baseline.

  • Wash the vulva (outside only) once a day with warm water; skip douching and skip scented washes, wipes, and vaginal deodorants.
  • Use only mild, unscented soap on the outer area if you use soap at all, and rinse well.
  • Do not put anything inside the vagina to “clean” it; douching disrupts the normal flora and raises BV risk.
  • Wipe from front to back after using the bathroom to avoid spreading gut bacteria toward the vagina.
  • Change pads and tampons regularly during your period and avoid leaving tampons in for long stretches.

Clothing, Sweat, and Moisture

BV‑related bacteria love warmth and trapped moisture.

  • Choose breathable cotton underwear and avoid very tight or synthetic bottoms when you can.
  • Change out of damp gym clothes or swimsuits as soon as possible after exercise or swimming.
  • Sleep in loose shorts or no underwear sometimes to let the area stay dry and ventilated.

Sex, Partners, and Protection

You cannot fully “sex‑proof” BV, but you can lower the odds of imbalance.

  • Use condoms or other barrier protection for any penetrative sex; semen can raise vaginal pH and BV risk.
  • Limit number of sexual partners or aim for mutually monogamous relationships; more partners are linked with higher BV rates.
  • Clean sex toys after every use (with soap and water or as manufacturer advises), and avoid sharing toys or always use a condom on them.
  • Get regular STI screening if you’re sexually active with new or multiple partners, since BV can make it easier to get STIs and vice versa.

If you notice a strong “fishy” odor, especially after sex, plus thin discharge, that’s a common BV pattern and worth getting checked.

Food, Probiotics, and Lifestyle

There’s growing (but not perfect) evidence that your overall habits can support a healthier vaginal microbiome.

  • Include probiotic‑rich foods like yogurt or kefir with live cultures in your daily diet.
  • Emphasize fruits, leafy greens, whole grains, and lean proteins, and limit very high‑sugar diets, which may encourage harmful microbes.
  • Stay well hydrated; water supports general and vaginal health.
  • Consider oral or vaginal probiotics that contain Lactobacillus strains such as L. crispatus or L. rhamnosus for recurrent BV, but ideally under guidance from a clinician.
  • Avoid smoking; smoking is associated with a higher BV risk.
  • Try to manage stress and get enough sleep; immune and hormonal shifts can affect your vaginal flora.

Some people with frequent recurrences, after proper antibiotic treatment, use short courses of vaginal boric acid suppositories to help stabilize pH, but these are not safe in pregnancy and should only be used with medical guidance.

When BV Keeps Coming Back

Recurrent BV (for example, four or more episodes per year) is common and frustrating.

  • Doctors may prescribe longer‑term or intermittent vaginal antibiotic gels to maintain balance.
  • Combined strategies—safe sex, hygiene changes, probiotic support, plus medical treatment—tend to work better than one thing alone.
  • If symptoms don’t fit classic BV or don’t respond to treatment, your clinician may check for other infections or less common bacteria like ureaplasma or mycoplasma, as patients sometimes discuss in forums.

“Quick Scoop” Checklist

Here’s a fast, practical checklist you can mentally run through each week:

  • No douching or scented vaginal products.
  • Gentle external wash only, front‑to‑back wiping.
  • Cotton underwear, quick change out of sweaty clothes and swimsuits.
  • Condoms and cleaned toys for sex; limit partner number.
  • Probiotic‑rich foods, lower sugar, no smoking if possible.
  • Talk to a clinician if you get recurrent fishy odor or discharge, especially if pregnant or trying to conceive.

If you’re having ongoing symptoms right now, or you’re pregnant, it’s important to see a healthcare provider because untreated BV can increase some pregnancy and STI‑related risks.
