 Bacterial Vaginosis

What is Bacterial Vaginosis?

Bacterial Vaginosis is caused by excessive growth of several types of bacteria, including Gardnerella vaginalis that may normally be present in your vagina. When these bacteria are present in large numbers, they can cause symptoms like discharge or odour.​

What are the symptoms of BV?

Not every woman with Bacterial Vaginosis presents with signs or symptoms. If you do present with symptoms, they can be like:

  • Thin white-grey vaginal discharge
  • Strong vaginal odour (fishy) that may worsen after unprotected sex or menses

What causes BV?


BV is not passed on between men and women during unprotected sexual intercourse. However, it is more
common among women with multiple sex partners and often develops soon after intercourse with a new partner. BV is also more common among women with female sex partners, where bacterial infection may be triggered by sharing vaginal fluids through insertion of fingers or sharing sex toys.


There is no condition equivalent to BV in men. BV may also be triggered by douching (washing inside the
vagina) which is not recommended, as it disturbs the balance of healthy and unhealthy bacteria in the
vagina.

What is the treatment for BV?

If you do not have any symptoms, treatment is usually not needed. Treatment may be necessary when:

  • You have symptoms
  • Doctor has noted signs of BV and bacteria present
  • If you are about to have a procedure that could allow bacteria into the uterus (such as termination of
    pregnancy)  
  • If you are pregnant BV is usually treated with oral antibiotics (Metronidazole). If you are unable to take Metronidazole, other drugs like Tinidazole oral tablets, Clindamycin vaginal cream, or Miconazole vaginal pessaries can be given.
    If you are prescribed with Metronidazole, it is important for you to avoid alcohol consumption when taking
    this medication.
