Bacterial Vaginosis or Yeast Infection: How to Tell the Difference

Bacterial vaginosis (BV) and yeast infections are two of the most common vaginal infections in women, and while they may share some similar symptoms, they are caused by different organisms and need different treatments. Knowing how to tell the difference is key to getting the right care.


🦠 What Causes Them?

  • Bacterial Vaginosis (BV):
    Caused by an imbalance of vaginal bacteria—too much of certain harmful bacteria and too little of good ones like Lactobacillus.
  • Yeast Infection:
    Caused by an overgrowth of Candida, a type of fungus (yeast) that naturally lives in the vagina in small amounts.

🔍 Key Differences in Symptoms

Burning SensationPossible during urinationCommon, especially during urination or sex
Redness/SwellingLess commonMore common around vulva area

đź§Ş Diagnosis

If you're unsure, a quick visit to the doctor or lab can help:

  • A vaginal swab can determine if it’s BV, yeast, or something else.
  • BV is diagnosed by testing the pH (BV usually has a high pH), presence of clue cells, and fishy odor.
  • Yeast infections are confirmed by spotting Candida cells under a microscope.

đź’Š Treatment Options

  • For BV:
    Treated with antibiotics. Avoid douching or scented products.
  • For Yeast Infection:
    Treated with antifungal medications.

👉 Don’t self-treat without knowing for sure—treating the wrong one can make symptoms worse.


🛡️ Prevention Tips

  • Wear breathable cotton underwear
  • Avoid douching or harsh feminine washes
  • Practice safe sex and maintain good hygiene
  • Wipe from front to back after using the toilet
  • Eat probiotic-rich foods like yogurt to support healthy vaginal flora

📝 Final Note

While both BV and yeast infections are common and treatable, they are not the same. If symptoms persist, keep recurring, or you’re unsure which one it is, see a healthcare professional for proper diagnosis and treatment. Your body will thank you!
