bacterial vaginosis during pregnancy

3 min read 13-03-2025

Bacterial vaginosis (BV) is a common vaginal infection caused by an imbalance of bacteria in the vagina. While BV usually isn't serious for non-pregnant individuals, it can pose some risks during pregnancy. This article provides essential information about BV during pregnancy, its symptoms, diagnosis, treatment, and potential complications.

Understanding Bacterial Vaginosis (BV)

BV occurs when the healthy bacteria in the vagina are replaced by an overgrowth of other types of bacteria. This shift in the vaginal flora can lead to various symptoms. It's crucial to understand that BV is not a sexually transmitted infection (STI), although sexual activity can sometimes be a contributing factor.

Symptoms of BV During Pregnancy

The symptoms of BV can vary, and some pregnant women may not experience any noticeable symptoms at all. Common symptoms include:

A thin, grayish-white vaginal discharge
A fishy odor, especially after sexual intercourse
Vaginal itching or burning
Slight abdominal discomfort

The absence of symptoms doesn't mean BV isn't present. Regular prenatal checkups are vital for early detection.

Diagnosis of BV During Pregnancy

Your doctor will likely perform a pelvic exam to assess your symptoms and collect a sample of vaginal discharge. This sample will be tested to confirm the presence of BV. The diagnostic criteria often involve assessing the vaginal pH level and the presence of clue cells (vaginal cells with bacteria attached).

Risks and Complications of BV During Pregnancy

Untreated BV during pregnancy can increase the risk of several complications, including:

Preterm labor and delivery: BV is linked to a higher chance of premature birth. The infection may trigger inflammation and contractions.
Preterm premature rupture of membranes (PPROM): This refers to the premature breaking of the amniotic sac.
Postpartum endometritis: This is an infection of the uterine lining after childbirth.
Chorioamnionitis: This is an infection of the amniotic fluid and membranes surrounding the fetus.
Low birth weight: Babies born prematurely often have lower birth weights.

It's important to note that correlation doesn't equal causation. While BV is associated with these risks, other factors can also contribute.

Treatment for BV During Pregnancy

Treatment for BV during pregnancy typically involves antibiotics. Your doctor will prescribe a course of oral or topical antibiotics, often metronidazole or clindamycin. It's crucial to complete the entire course of antibiotics, even if symptoms improve, to ensure the infection is fully eradicated.

Important Considerations: What to Ask Your Doctor

Are there any potential side effects of the prescribed antibiotics? Some antibiotics can have mild side effects like nausea or diarrhea.
What can I do to prevent BV recurrence? Maintaining good hygiene practices can help reduce the risk. However, BV can be recurrent.
Will BV affect my baby during delivery? In most cases, BV treatment effectively addresses the infection, minimizing the risk to the baby. However, monitoring during labor is sometimes recommended.
How frequently should I have my vagina checked during pregnancy for BV? Discuss a screening plan with your doctor.

Preventing BV During Pregnancy

While there's no foolproof way to prevent BV, certain practices can reduce the risk:

Maintain good hygiene: Wash the vulva and surrounding area with mild soap and water daily. Avoid douching, which can disrupt the natural balance of vaginal bacteria.
Use condoms: While BV is not an STI, practicing safe sex can reduce the risk of other infections.
Avoid scented products: Avoid using scented feminine hygiene products, which can irritate the vagina and disrupt the delicate bacterial balance.
Avoid tight clothing: Wear loose-fitting underwear and clothing made of breathable fabrics, such as cotton.
Regular prenatal care: Regular checkups allow for early detection and timely treatment.
