Bacterial Vaginosis

Bacterial vaginosis (BV) is the most common vaginal infection in women of reproductive age. It occurs when the normal balance of bacteria in the vagina is disrupted, leading to an overgrowth of Gardnerella vaginalis, along with other anaerobic bacteria. While not considered a sexually transmitted infection (STI), BV is strongly associated with sexual activity. ### Bacterial Vaginosis Causes and Risk Factors The exact cause of BV is unknown, but several factors can increase the risk: - New or multiple sexual partners: BV is more common in women who are sexually active, particularly those with new or multiple partners. - Douching: Douching disrupts the natural balance of bacteria in the vagina. - Lack of vaginal lactobacilli: Lactobacilli are "good" bacteria that help maintain a healthy vaginal environment. Low levels can increase BV risk. - Smoking: Smoking is associated with an increased risk of BV. ### Symptoms of Bacterial Vaginosis Many women with BV experience no symptoms. When symptoms do occur, they may include: - Abnormal vaginal discharge: This may be thin, gray or white. - Abnormal vaginal smell: This may be a strong or fishy odor, especially after sex. - Vaginal itching or burning. - Burning during urination ### BV and Sexual Health - Increased STI risk: BV can increase the risk of acquiring STIs such chlamydia and gonorrhea, among others. This is likely because the imbalance of bacteria in the vagina makes it easier for these infections to take hold. - Transmission between female partners: BV can be transmitted between female sexual partners. - Impact on pregnancy: BV during pregnancy has been shown to increase the risk of premature birth and low birth weight. ### Diagnosis, Treatment, and Prevention BV is usually diagnosed through a pelvic exam and laboratory tests. Treatment typically involves antibiotics, usually in the form of pills or vaginal creams. ### Prevention While the exact cause of BV is not fully understood, the following steps may help reduce the risk: - Avoid douching: The vagina is self-cleaning, and douching can disrupt its natural balance. - Practice safe sex: Use condoms consistently to reduce the risk of STIs. STIs can can increase the risk of BV. - Limit the number of sexual partners: Having multiple partners increases the risk of BV. - If you are a woman who has sex with women, talk to your partner(s) about their sexual history and any symptoms they may be experiencing. Remember: BV is a common condition, and it's nothing to be ashamed of. If you think you may have BV, see a healthcare provider for diagnosis and treatment.
