Causes    TOP

A mix of healthy and unhealthy bacteria is normally found in the vagina. Bacterial vaginosis occurs when there is an increase in the amount of unhealthy bacteria. The increase causes a decrease in good bacteria. This imbalance can lead to symptoms.

It is not clear exactly what causes the increase in unhealthy bacteria.

Risk Factors    TOP

Factors that may increase your chance of bacterial vaginosis include:

  • Antibiotic use
  • Smoking
  • Douching
  • Having a new sexual partner or multiple partners
  • Having sex without a condom
  • Using an intrauterine device (IUD) for birth control

Any woman can get bacterial vaginosis, including those who have never had sex.

Symptoms    TOP

Some women with bacterial vaginosis do not have any symptoms.

Symptoms that can develop include:

  • Itching around the vagina
  • Vaginal irritation
  • Burning feeling while urinating
  • Abnormal vaginal discharge:
    • Color: white or gray
    • Consistency: thin, foamy, or watery
    • Odor: fish-like, especially after sex

There are several different conditions that can cause these symptoms. Your doctor will help you determine the cause of your symptoms.

Diagnosis    TOP

You will be asked about your symptoms, and medical and sexual history. A physical exam will be done. This will include a pelvic exam.

Fluid from your vagina may be tested to look for specific bacteria or other infectious agents.

Treatment    TOP

Bacterial vaginosis can lead to complications such as an increased risk of:

The main course of treatment is prescription antibiotic pills or vaginal creams. Finish all medication as prescribed by your doctor even if the symptoms have gone away. This can prevent the infection from recurring.

Avoid sexual intercourse during treatment. If you do have sexual intercourse, use condoms. Usually, male sexual partners do not need to be treated. Talk with your doctor about the best treatment plan for you.

Prevention    TOP

To help reduce your chance of bacterial vaginosis:

  • Abstain from sex or remain monogamous.
  • Use condoms when having sex.
  • Do not use douches.
  • After bowel movements, wipe from front to back, away from the vagina.
