Bacterial vaginosis (BV) is a common condition that can lead to vaginal discomfort and pain. It arises from an imbalance in the natural bacteria present in the vagina. Maintaining a healthy vaginal environment depends on a delicate balance of bacteria. However, when certain types of bacteria proliferate excessively, it can disrupt this balance and result in BV.
Bacterial vaginosis can affect individuals of any age, but it is most prevalent during the reproductive years. Hormonal fluctuations during this period can create a more favorable environment for the overgrowth of specific bacteria. Furthermore, bacterial vaginosis is observed more frequently in sexually active individuals. While the exact connection remains unclear, practices such as unprotected sexual intercourse and douching are known to elevate the risk of developing BV.

Symptoms
The signs and symptoms of bacterial vaginosis may include:
- A thin vaginal discharge that can appear gray, white, or green.
- A distinct, unpleasant “fishy” odor emanating from the vagina.
- Itching in the vaginal area.
- A burning sensation experienced during urination.
It’s important to note that many individuals with bacterial vaginosis do not experience any noticeable symptoms.
When to See a Doctor
It is advisable to schedule an appointment with a healthcare professional in the following situations:
- If you observe an unusual vaginal discharge accompanied by discomfort. A doctor can accurately diagnose the cause of your symptoms.
- If you have a history of vaginal infections, but the current discharge seems different from previous occurrences.
- If you have a new sexual partner or multiple sexual partners. The symptoms of a sexually transmitted infection (STI) can sometimes mimic those of bacterial vaginosis.
- If you suspected a yeast infection and attempted self-treatment, but your symptoms persist.

What are the primary causes of bacterial vaginosis?
Bacterial vaginosis develops when there is a disruption in the normal balance of bacteria within the vagina. The vagina naturally hosts a variety of bacteria, collectively known as the vaginal flora. A healthy vaginal flora is characterized by a predominance of “good” bacteria over “bad” bacteria. Lactobacilli are considered the “good” bacteria, while anaerobes are classified as “bad” bacteria. The primary cause of bacterial vaginosis is an overgrowth of these anaerobic bacteria. When anaerobes become too abundant, they disrupt the delicate equilibrium of the vaginal flora, leading to bacterial vaginosis. This imbalance is what truly causes bacterial vaginosis and the associated symptoms.
Risk factors that contribute to bacterial vaginosis
Several factors can increase the likelihood of developing bacterial vaginosis. Understanding these risk factors is crucial for prevention and informed decision-making:
- Multiple or new sexual partners: While the precise relationship between sexual activity and bacterial vaginosis is still being investigated, it’s evident that BV occurs more frequently in individuals with multiple or new sexual partners. Notably, BV is also more common in relationships where both partners are female.
- Douching practices: The vagina possesses a natural self-cleaning mechanism. Therefore, rinsing the vagina with water or other solutions is generally unnecessary and can be detrimental. Douching disrupts the healthy bacterial balance in the vagina, potentially leading to an overgrowth of anaerobic bacteria and subsequently, bacterial vaginosis.
- Deficiency in naturally occurring lactobacilli: If the vagina does not produce a sufficient amount of lactobacilli, the protective barrier against the overgrowth of harmful bacteria weakens, increasing susceptibility to bacterial vaginosis.
Potential complications if bacterial vaginosis is left untreated
While bacterial vaginosis often resolves without causing significant complications, in some instances, it can lead to more serious health issues if left unaddressed:
- Increased susceptibility to sexually transmitted infections (STIs): Having BV elevates the risk of acquiring STIs, including HIV, herpes simplex virus, chlamydia, and gonorrhea. Furthermore, for individuals with HIV, bacterial vaginosis increases the likelihood of transmitting the virus to a sexual partner.
- Post-gynecological surgery infection risks: Bacterial vaginosis can increase the risk of developing infections following gynecological procedures such as hysterectomy or dilation and curettage (D&C).
- Pelvic Inflammatory Disease (PID): In some cases, bacterial vaginosis can ascend and trigger pelvic inflammatory disease (PID), an infection of the uterus and fallopian tubes. PID can have serious consequences, including an increased risk of infertility.
- Pregnancy-related concerns: Earlier research suggested a potential link between BV and pregnancy complications like preterm birth and low birth weight. However, more recent studies indicate that these risks may be associated with other factors, such as a history of premature delivery. Nevertheless, it is still recommended that pregnant individuals experiencing BV symptoms be tested and, if positive, receive appropriate treatment as determined by their doctor.
Prevention strategies for bacterial vaginosis
Adopting preventive measures can significantly reduce the risk of developing bacterial vaginosis:
- Avoid scented products in the vaginal area: Cleanse the genital area gently with warm water only. Scented soaps, washes, and other perfumed products can irritate delicate vaginal tissues. Opt for unscented tampons and pads.
- Refrain from douching: Douching is unnecessary for vaginal hygiene and can disrupt the natural vaginal flora, increasing the risk of infection. The vagina naturally cleanses itself through normal bathing.
- Practice safe sex: To minimize the risk of STIs, consistently use latex condoms or dental dams during sexual activity. Ensure proper cleaning of sex toys. Consider limiting the number of sexual partners or abstaining from sexual activity.
