Bacterial vaginosis (back TEER ee ahl vaj ih NO siss) or BV is an infection of the vagina. This is a common infection. Females of any age can have it. You do not have to be sexually active to get it. Bacterial vaginosis is not a sexually transmitted disease. It is an overgrowth of specific anaerobic bacteria (bacteria that do not need oxygen to grow) in the vagina.
The exact cause of this overgrowth is not known. It is more common in women who have had sex with more than one person. It is more common in women who use vaginal douches or feminine hygiene products that disrupt the normal bacterial balance in the vagina. Since the causes of BV are not known, there is not a specific way to prevent it.
Products that interfere with your vagina’s natural bacteria balance can cause the bacteria to grow irregularly. These products include douches (genital cleansing products) or certain soap products. It is best to avoid using these products. If you do use soap, stay away from products that are scented or colored. Instead, use a mild unscented soap.
Women with BV report a fishy-smelling discharge (fluid) that is white to gray in color. The odor may seem worse around the time of your period, or after having sex. You may notice other symptoms such as itchiness or redness in the genital area. You may have pain when having sex.
To diagnose BV your doctor will need to test the vaginal discharge. The doctor will use a swab to take a sample the discharge. During the exam the doctor will first examine the outside of the genitalia (the vulva). The doctor may insert the swab into the vagina.
Sometimes it is necessary to insert a speculum into the vagina. A speculum is a tool that gently moves the walls of the vagina apart. This allows the doctor to get a better look inside.
A swab of the discharge is sent to the lab. It may be looked at under a microscope in the office. This helps the doctor determine if you have BV or any other vaginal infection.
Bacterial Vaginosis may increase your risk of having a pre-term delivery (a baby born too early).
BV can also increase your chances of getting an infection called Pelvic Inflammatory Disease (PID). This is an infection of the uterus, fallopian tubes, or ovaries. These are internal organs that you cannot see. PID can:
Getting treatment for BV lowers your risk of getting PID.
If you have BV your doctor may prescribe either a cream or gel to insert into the vagina. Or your doctor may prescribe oral (taken by mouth) antibiotics.
Though BV can be treated, it may come back again. If you experience symptoms again, contact your health care provider.
