Defining Bacterial Vaginosis
Bacterial vaginosis (BV) is a common vaginal infection that occurs when the delicate balance of bacteria in the vagina is disrupted. It happens when the normal lactobacilli, which are beneficial bacteria, are overgrown by other types of bacteria, primarily anaerobic bacteria such as Gardnerella vaginalis, Prevotella, Mobiluncus, and Megasphaera.
What is BV?
BV is characterized by a thin, grayish-white vaginal discharge with a strong, fishy odor, especially after sexual intercourse. Some women may also experience vaginal itching and burning during urination. However, it’s important to note that many women with BV do not exhibit any symptoms.
BV is not considered a sexually transmitted infection (STI), but sexual activity can increase the risk of developing the condition. Other factors that may contribute to the development of BV include douching, smoking, and having multiple sexual partners.

Prevalence and Statistics
BV is the most common vaginal infection among women of reproductive age, affecting millions worldwide. In the United States alone, it is estimated that 29.2% of women aged 14-49 are affected by BV. The prevalence of BV varies by race and ethnicity, with African American women having the highest rates of infection.
Studies have shown that BV is more common in women who:
- Are sexually active
- Have multiple sexual partners
- Use intrauterine devices (IUDs)
- Douche frequently
Despite its high prevalence, BV often goes undiagnosed and untreated, which can lead to various complications, including an increased risk of acquiring sexually transmitted infections (STIs) such as chlamydia, gonorrhea, and HIV. Pregnant women with untreated BV are also at a higher risk of preterm delivery and low birth weight babies.
Identifying Symptoms
Bacterial vaginosis (BV) often presents with a range of symptoms, although some women may not experience any noticeable signs. Recognizing the primary and secondary symptoms of BV is crucial for seeking timely medical attention and preventing potential complications.
Primary Symptoms
The most common and distinctive symptom of bacterial vaginosis is an abnormal vaginal discharge. This discharge typically has the following characteristics:
- Off-white, gray, or greenish in color
- Thin and watery consistency
- Strong, unpleasant, fishy odor, especially after sexual intercourse
In addition to the abnormal discharge, some women with BV may experience vaginal itching or irritation, although this is less common compared to other vaginal infections like yeast infections.
Secondary Symptoms
While not as prevalent as the primary symptoms, some women with bacterial vaginosis may also report:
- Burning sensation during urination
- Discomfort or pain during sexual intercourse
It is important to note that up to 84% of women with BV may not exhibit any symptoms at all. This asymptomatic nature of BV can make it challenging to detect and treat the infection promptly.
Due to the similarity of BV symptoms to other vaginal infections, such as yeast infections or sexually transmitted infections (STIs), it is crucial to consult a healthcare provider for an accurate diagnosis. A proper diagnosis will ensure that the appropriate treatment is prescribed, reducing the risk of potential complications and recurrence of the infection.
Causes and Risk Factors
Bacterial vaginosis is caused by an imbalance in the vaginal microbiome, where the normally dominant Lactobacillus species are overrun by other types of bacteria, primarily anaerobic bacteria such as Gardnerella vaginalis, Prevotella, Mobiluncus, and Megasphaera.
Microbiome Imbalance
The delicate balance of bacteria in the vagina can be disrupted by various factors, leading to the overgrowth of harmful bacteria. This imbalance creates an environment that is conducive to the development of bacterial vaginosis. Some of the factors that may contribute to this imbalance include:
- Douching
- Smoking
- Having multiple sexual partners
- Use of intrauterine devices (IUDs)
While bacterial vaginosis is not considered a sexually transmitted infection (STI), sexual activity can increase the risk of developing the condition.
Common Risk Factors
Certain behaviors and factors can increase a woman’s likelihood of developing bacterial vaginosis:
- Being sexually active
- Having multiple sexual partners
- Douching frequently
- Not using condoms or dental dams during sexual activity
- Being pregnant
- Being of African-American descent
- Having an intrauterine device (IUD), especially if accompanied by irregular bleeding
Studies have shown that bacterial vaginosis is more common in women who engage in these behaviors or possess these risk factors. Pregnant women are particularly susceptible to bacterial vaginosis due to hormonal changes that occur during pregnancy, with about 1 in 4 pregnant women developing the condition.
It is important to note that while these risk factors increase the likelihood of developing bacterial vaginosis, the condition can still occur in women who do not exhibit any of these factors. Understanding the causes and risk factors associated with bacterial vaginosis is crucial for prevention, early detection, and appropriate treatment.
How is BV Diagnosed?
Diagnosing bacterial vaginosis (BV) requires a comprehensive approach that involves both clinical tests performed by healthcare providers and self-assessment of symptoms. Accurate diagnosis is crucial for determining the appropriate treatment plan and preventing potential complications.
Clinical Tests
Healthcare providers diagnose BV through a combination of physical examination and laboratory testing of vaginal discharge samples. During a pelvic exam, the provider visually inspects the vagina for signs of infection, such as increased discharge with a white or gray color. They then collect a sample of vaginal fluid using a swab or spatula for further analysis.
The collected sample undergoes various laboratory tests to confirm the presence of BV:
- Wet mount: The sample is placed on a glass slide and examined under a microscope for the presence of bacteria, white blood cells, and clue cells (vaginal cells covered with bacteria).
- Whiff test: The provider mixes the sample with a special solution to check for a strong, fishy odor, which is indicative of BV.
- Vaginal pH test: The acidity of the vaginal fluid is measured. A pH higher than 4.5 suggests an imbalance in the vaginal flora, supporting a BV diagnosis.
- DNA test (PCR): In some cases, the genetic material of the sample is analyzed to identify specific bacterial strains associated with BV. This test is more expensive and less commonly used.
To ensure accurate results, patients are advised to avoid douching, using vaginal sprays or irritants, engaging in sexual activity, and using tampons for 24 hours before the examination. Additionally, scheduling the exam when not menstruating is recommended.

Self Symptoms Check
Women can also play an active role in identifying potential BV infections by being aware of the common symptoms:
- Increased vaginal discharge with a thin, grayish-white appearance
- Strong, unpleasant, fishy odor, especially after sexual intercourse
- Vaginal itching or irritation
- Burning sensation during urination
If any of these symptoms are present, it is essential to consult a healthcare provider for proper diagnosis and treatment. At-home BV testing kits are available, which involve collecting a vaginal fluid sample and sending it to a laboratory for analysis. However, it is crucial to share the results with a provider to ensure appropriate care.
Vaginal pH test kits are also available over-the-counter, using a swab or paper strip that changes color when exposed to vaginal fluid. While a high pH may indicate BV, it is not a definitive diagnosis. Discussing the results with a healthcare provider is recommended for accurate interpretation and guidance.
In conclusion, diagnosing bacterial vaginosis involves a combination of clinical tests performed by healthcare providers and self-assessment of symptoms. By working closely with their providers and being proactive in recognizing potential signs of infection, women can receive timely and effective treatment for BV, minimizing the risk of complications and promoting overall vaginal health.

Antibiotics are the mainstay of therapy for bacterial vaginosis. The preferred medications include:
- Secnidazole (Solosec): A single-dose oral treatment (2 grams) approved by the FDA in 2017 for the treatment of BV in women aged 12 years and older.
Over-the-Counter Solutions
While antibiotics are the most effective treatment for BV, some over-the-counter solutions may help manage symptoms or prevent recurrence:
- Probiotics: Oral or vaginal probiotic supplements containing Lactobacillus species may help restore the natural balance of bacteria in the vagina and prevent BV recurrence.
- Boric acid suppositories: Vaginal suppositories containing boric acid may be helpful in treating BV, although more research is needed to fully assess their effectiveness.
Natural Remedies
Some natural remedies have been suggested for managing BV symptoms, although their effectiveness is not as well-established as medical treatments:
- Garlic: Oral garlic supplements may have antibacterial properties that could help combat BV-causing bacteria. However, garlic should never be placed directly in the vagina.
- Tea tree oil: Limited anecdotal evidence suggests that tea tree oil may have antimicrobial properties, but its safety and effectiveness for treating BV have not been thoroughly studied.
It is essential for individuals experiencing BV symptoms to consult with a healthcare provider before attempting any home remedies, as some may cause allergic reactions or interact with other medications. Proper diagnosis and treatment by a medical professional are crucial for effectively managing BV and preventing potential complications.
