Signs and symptoms of bacterial vaginosis

Women with BV may have an abnormal vaginal discharge with an unpleasant odor. Some women report a strong fish-like odor, especially after intercourse. Discharge, if present, is usually white or gray; it can be thin. Women with BV may also have burning during urination or itching around the outside of the vagina, or both. However, most women with BV report no signs or symptoms at all.

What are the complications of bacterial vaginosis?

In most cases, BV causes no complications. But there are some serious risks from BV including:

·         Having BV can increase a woman's susceptibility to HIV infection if she is exposed to the HIV virus.

·         Having BV increases the chances that an HIV-infected woman can pass HIV to her sex partner.

·         Having BV has been associated with an increase in the development of an infection following surgical procedures such as a hysterectomy or an abortion.

·         Having BV while pregnant may put a woman at increased risk for some complications of pregnancy, such as preterm delivery.

·         BV can increase a woman's susceptibility to other STDs, such as herpes simplex virus (HSV), chlamydia, and gonorrhea.

How does bacterial vaginosis affect a pregnant woman and her baby?

Pregnant women with BV more often have babies who are born premature or with low birth weight (low birth weight is less than 5.5 pounds).
The bacteria that cause BV can sometimes infect the uterus (womb) and fallopian tubes (tubes that carry eggs from the ovaries to the uterus). This type of infection is called pelvic inflammatory disease (PID). PID can cause infertility or damage the fallopian tubes enough to increase the future risk of ectopic pregnancy and infertility. Ectopic pregnancy is a life-threatening condition in which a fertilized egg grows outside the uterus,
usually in a fallopian tube which can rupture.

How is bacterial vaginosis diagnosed?

A health care provider must examine the vagina for signs of BV and perform laboratory tests on a sample of vaginal fluid to look for bacteria associated with BV.
