Bacterial Vaginosis: Understanding, Treating, and Preventing This Common Vaginal Condition

Bacterial Vaginosis—often called BV—is one of the most common vaginal conditions in women of reproductive age, yet many people are unfamiliar with it or mistake it for other infections. BV occurs when the natural balance of bacteria in the vagina is disrupted, allowing certain types of bacteria to grow excessively. While BV is usually not serious, it can cause uncomfortable symptoms, increase the risk of other infections, and sometimes lead to complications if untreated.

At Intrepid Health, we believe that knowledge is a powerful tool for women’s health. Understanding BV—its causes, symptoms, and treatments—can help you take control of your reproductive well-being and seek timely care.

What Is Bacterial Vaginosis?

The vagina normally contains a delicate balance of bacteria, with “good” bacteria—primarily Lactobacillus—playing a key role in maintaining a healthy, slightly acidic environment (pH around 3.8–4.5). This acidity helps prevent harmful bacteria and yeast from multiplying.

BV happens when the number of Lactobacillus decreases and other types of bacteria, such as Gardnerella vaginalis and anaerobic bacteria, overgrow. This shift raises the vaginal pH and leads to symptoms—or sometimes no symptoms at all.

Who Can Get BV?

BV can occur in any woman, but certain factors increase the risk:

• Being sexually active (though BV is not considered a classic sexually transmitted infection)
• Having multiple or new sexual partners
• Vaginal douching
• Using scented soaps, sprays, or feminine hygiene products
• A history of BV or other vaginal infections
• Smoking

It’s important to note that BV can also occur in women who are not sexually active—meaning lifestyle and vaginal microbiome changes play a significant role.

Symptoms of Bacterial Vaginosis

Up to half of women with BV have no symptoms at all. When symptoms are present, they may include:

• Thin, watery discharge that is often grey or white
• Strong fishy odour, which may be more noticeable after sexual intercourse
• Mild vaginal itching or irritation
• Burning sensation during urination (less common)

Unlike yeast infections, BV typically does not cause thick, clumpy discharge or significant redness and swelling.

How Is BV Different from a Yeast Infection?

BV and yeast infections are both common causes of vaginal symptoms, but they are caused by very different organisms:

• BV – caused by an overgrowth of bacteria; often produces a fishy odour and thin discharge.
• Yeast infection – caused by an overgrowth of Candida fungus; often produces thick, cottage cheese–like discharge with intense itching.

The treatments for each are also different—antibiotics for BV vs. antifungal medications for yeast—so getting the right diagnosis is essential.

Potential Complications of BV

While BV is often mild, untreated cases can increase the risk of:

• Sexually transmitted infections (including HIV) due to changes in the vaginal barrier
• Pelvic inflammatory disease (PID) if harmful bacteria spread to the uterus or fallopian tubes
• Pregnancy-related complications, such as preterm birth or low birth weight
• Post-surgical infections after gynaecological procedures

These risks make timely diagnosis and treatment important, even if symptoms are mild or absent.

Diagnosis

Your healthcare provider will:

• Ask about symptoms and risk factors
• Perform a pelvic exam to check for discharge or odour
• Collect a vaginal fluid sample to check pH and look for bacteria under a microscope

A diagnosis of BV is typically confirmed if:

1. Vaginal pH is above 4.5
2. Thin, homogenous discharge is present
3. Clue cells (vaginal cells coated with bacteria) are seen under a microscope
4. A fishy odour is detected, especially after adding potassium hydroxide to the sample (the “whiff test”)

Treatment Options

BV is usually treated with antibiotics, either:

• Metronidazole (oral tablets or vaginal gel)
• Clindamycin (vaginal cream or oral capsules)

Treatment typically lasts 5–7 days. It’s important to:

• Complete the full course even if symptoms improve early
• Avoid alcohol while taking metronidazole (can cause severe nausea)
• Avoid sexual intercourse or use condoms during treatment to reduce recurrence risk

For pregnant women, treating BV is especially important due to the link with preterm birth.

What About Recurrence?

BV can come back in some women, sometimes within a few months. To reduce recurrence:

• Avoid douching or scented vaginal products
• Practice safe sex (condoms may help reduce recurrence)
• Discuss with your provider whether probiotic supplements or vaginal suppositories may help restore healthy bacteria
• Treat both symptomatic and asymptomatic BV during pregnancy or before gynaecologic surgery

Self-Care and Prevention Strategies

While BV isn’t always preventable, these steps can lower your risk:

1. Maintain vaginal balance – avoid harsh soaps or perfumed products in the vaginal area.
2. Use protection – condoms can reduce BV recurrence in some women.
3. Limit sexual partners – having multiple or new partners can alter vaginal bacteria.
4. Avoid douching – this disrupts the natural bacterial balance.
5. Wear breathable underwear – cotton fabrics help reduce moisture build-up.

When to See a Doctor

Seek medical evaluation if you notice:

• Vaginal odour or unusual discharge
• Recurring symptoms after previous treatment
• Symptoms during pregnancy
• Pain during sex or urination
• Fever or pelvic pain (may indicate a more serious infection)

Prompt care ensures the right diagnosis and treatment, helping you avoid complications and feel more comfortable.

BV and Your Sexual Health

While BV is not officially classified as an STI, sexual activity can influence its development and recurrence. Open communication with your healthcare provider about your sexual history helps guide the best prevention and management plan.
