Bacterial vaginosis (BV) is a bacterial infection in the vagina. It is the most common cause of abnormal vaginal odor and discharge in young women and is caused by a change in the balance and type of bacteria which are normally present in the vagina.
Although BV is not considered a sexually transmitted disease, the risk of developing BV seems to increase the more sexual partners a woman has.
Normally, Lactobacillus bacteria are the most common type of bacteria within the vagina. These produce chemicals that keep the vagina mildly acidic. In BV, numbers other types of bacteria within the vagina that are usually only present in small numbers increase and disrupt both the pH of the vagina and its lining. This can result in BV, and symptoms may include:
Mild itching in and around the vagina
Bad-smelling, fishy odor that is more noticeable during menstruation or after sex)
Pain when urinating.
Some women with BV have no symptoms, which is a bit concerning because if BV isn’t treated it can increase the chance of women developing STD’s (such as chlamydia, herpes, HIV or gonorrhea), pelvic inflammatory disease, and possibly increase the risk of miscarriage. In women who are pregnant, BV can result in premature labor and delivery, premature rupture of membranes, and postpartum uterine infections.
Who is at Risk of Developing Bacterial Vaginosis
Experts are not sure what causes this imbalance of bacteria to occur in the first place but have identified a few risk factors that make some women a lot more likely to develop BV. These include:
A history of multiple sex partners
A new sexual partner
Cigarette smoking
Vaginal douching
Presence of an intrauterine contraceptive device (IUD).
Although most risk factors are associated with sexual activity, women who have never had vaginal intercourse can also develop BV.
How is Bacterial Vaginosis Diagnosed?
If you have symptoms of BV or have a history of multiple or a new sexual partner, then make an appointment with your doctor. Your doctor or nurse practitioner will ask you about any symptoms and take a history and then perform an examination. A swab may be taken of your vaginal fluid which will be tested in a laboratory. Other possible causes will be ruled out before they arrive at a diagnosis of BV.
How is Bacterial Vaginosis Treated?
Antibiotics prescribed by your doctor are usually necessary to treat BV. These may be in the form of tablets or vaginal creams. BV tends to recur, so you may need to take more than one course of antibiotics. Always finish the course of treatment prescribed, even if you feel better halfway through.
Male sexual partners don’t normally need to be treated for BV; however, female sexual partners will need treatment.

Pregnancy Category
A
Adequate and well-controlled studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).
B
Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women.
C
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use in pregnant women despite potential risks.
D
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use in pregnant women despite potential risks.
X
Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use in pregnant women clearly outweigh potential benefits.
