Overview

Bacterial vaginosis may be a sort of vaginal inflammation caused by the overgrowth of bacteria naturally found within the vagina, which upsets the natural balance.

Women in their reproductive years are presumably to urge bacterial vaginosis, but it can affect women of any age. The cause isn't completely understood, but certain activities, like unprotected sex or frequent douching, increase your risk.

Symptoms

Bacterial vaginosis signs and symptoms may include:

Ø  Thin, gray, white or green vaginal discharge

Ø  Foul-smelling "fishy" vaginal odor

Ø  Vaginal itching

Ø  Burning during urination

When to see a doctor

Make an appointment to see your doctor if:

Ø    You have vaginal discharge that's new and associated with an odor or fever. Your doctor can help determine the cause and identify signs and symptoms.

Ø     You've had vaginal infections before, but the color and consistency of your discharge seems different this time.

Ø    You have multiple sex partners or a recent new partner. Sometimes, the signs and symptoms of a sexually transmitted infection are almost like those of bacterial vaginosis.

Ø    You try self-treatment for a yeast infection with an over-the-counter treatment and your symptoms persist.

Causes

Bacterial vaginosis results from overgrowth of 1 of several bacteria naturally found in your vagina. Usually, "good" bacteria (lactobacilli) outnumber "bad" bacteria (anaerobes). But if there are too many anaerobic bacteria, they upset the natural balance of microorganisms in your vagina and cause bacterial vaginosis.

Risk factors

Risk factors for bacterial vaginosis include:

Ø     Having multiple sex partners or a new sex partner. Doctors don't fully understand the link between sexual activity and bacterial vaginosis, but the condition occurs more often in women who have multiple sex partners or a new sex partner. Bacterial vaginosis also occurs more frequently in women who have sex with women.

Ø     Douching. The practice of rinsing out your vagina with water or a cleansing agent (douching) upsets the natural balance of your vagina. This can lead to an overgrowth of anaerobic bacteria, and cause bacterial vaginosis. Since the vagina is self-cleaning, douching isn't necessary.

Ø     Natural lack of lactobacilli bacteria. If your natural vaginal environment doesn't produce enough of the good lactobacilli bacteria, you're more likely to develop bacterial vaginosis.

Complications

Bacterial vaginosis doesn't generally cause complications. Sometimes, having bacterial vaginosis may lead to:

Ø     Preterm birth - In pregnant women, bacterial vaginosis is linked to premature deliveries and low birth weight babies.

Ø     Sexually transmitted infections - Having bacterial vaginosis makes women more vulnerable to sexually transmitted infections, like HIV, herpes simplex virus, chlamydia or gonorrhea. If you've got HIV, bacterial vaginosis increases the chances that you're going to pass the virus on to your partner.

Ø     Infection risk after gynecologic surgery - Having bacterial vaginosis may increase the danger of developing a post-surgical infection after procedures like hysterectomy or dilation and curettage (D&C).

Ø     Pelvic inflammatory disease (PID) - Bacterial vaginosis can sometimes cause PID, an infection of the uterus and therefore the fallopian tubes which will increase the danger of infertility.

Prevention

To help prevent bacterial vaginosis:

Ø     Minimize vaginal irritation. Use mild, non-deodorant soaps and unscented tampons or pads.

Ø     Don't douche - Your vagina doesn't require cleansing aside from normal bathing. Frequent douching disrupts the vaginal balance and should increase your risk of vaginal infection. Douching won't clear up a vaginal infection.

Ø     Avoid a sexually transmitted infection - Use a male latex condom, limit your number of sex partners or abstain from intercourse to minimize your risk of a sexually transmitted infection.
