Bacterial Vaginosis

What is bacterial vaginosis?

Bacterial vaginosis is a common vaginal infection caused by an abnormal growth of natural bacteria found in the vagina. The normal balance of bacteria may be altered by taking antibiotics or other drugs, using perfumed soaps or bubble bath products, or douching. Bacterial vaginosis is not considered a sexually transmitted infection.

Symptoms

• Itching and swelling of the vagina and vaginal lips (vulva).
• Foul smelling, thin, grey vaginal discharge.
• Sex may be painful.

Approximately 50 percent of women do not have any symptoms (asymptomatic).

Testing

This infection can be diagnosed by a physician's exam and a swab taken from the vagina.

Treatment

Asymptomatic

Treatment is not necessary unless you are pregnant or you are scheduled for an intrauterine device (IUD) insertion, therapeutic abortion, or other gynaecological surgery.

Symptomatic

If you have symptoms, bacterial vaginosis is usually treated with an antibiotic called metronidazole (Flagyl). Your sexual partner does not require treatment.

Prevention

• Limit the number of sexual partners you have.
• Do not douche.
• Avoid using perfumed soaps or bubble bath products.
