Understanding BV Discharge
Bacterial vaginosis (BV) is a common vaginal infection that affects nearly 30% of women ages 14-49 in the United States. It occurs when there is an overgrowth of bacteria in the vagina, disrupting the natural microbial balance. While BV is not considered an STD, it can increase a woman's susceptibility to contracting STIs. Understanding the signs, symptoms, and discharge associated with BV can help with getting an accurate diagnosis and proper treatment.
What Causes BV?
While the exact cause of BV is not fully understood, certain factors are associated with its development:
- Having a new sex partner or multiple partners
- Douching
- Using an intrauterine device (IUD) for birth control
- Menstruation
- Smoking
BV is linked to an imbalance between healthy and harmful bacteria in the vagina. The condition can sometimes develop without any clear trigger as well.
BV Symptoms
The most common symptoms of bacterial vaginosis include:
- Thin, gray, white or green vaginal discharge
- Fishy odor, especially after sex or during menstruation
- Burning sensation during urination
- Itching around the outside of the vagina
However, many women with BV experience no symptoms at all. Testing the vaginal discharge under a microscope can confirm the presence of BV.
BV Discharge Appearance and Smell
The discharge caused by bacterial vaginosis has some typical characteristics that differ from healthy vaginal secretions or discharge caused by other infections.
Gray, White or Greenish Discharge
BV discharge is often thin and watery with a gray, white or greenish color. The greenish tint is from the increased anaerobic bacteria associated with BV. The discharge is also homogenous, meaning it has a uniform color and texture throughout.
"Fishy" Odor
One of the signature signs of bacterial vaginosis discharge is a fishy odor, especially after intercourse. This smell is from the overgrowth of anaerobic bacteria releasing amines during the metabolism of amino acids.
Amount of Discharge
BV discharge can be excessive in amount, sometimes described as frothy or foamy. This is from the increased presence of bacteria and inflammation in the vagina.
pH Level
The normal vaginal pH is around 3.8 to 4.5. In bacterial vaginosis, the pH rises above 4.5. This higher pH promotes the growth of harmful bacteria.
BV Discharge Pictures
BV discharge can have visual characteristics that differ from a healthy discharge or other infections. Below are some pictures illustrating the common features of BV discharge:
Thin, Grayish Discharge
BV discharge is often thin and grayish in color, as seen on this vaginal swab sample.
White, Homogeneous Discharge
The white discharge in BV can be thick, but it usually has an even color and texture as seen here.
Greenish Discharge
The anaerobic bacteria in BV can sometimes give the discharge a greenish tinge, as pictured on this vaginal swab.
Comparing BV Discharge to Other Infections
Looking at the visual symptoms and assessing factors like odor, color and amount can help differentiate BV discharge from other vaginal infections.
Yeast Infection Discharge
- Thick, white, cottage cheese-like
- No odor
- Caused by Candida fungus overgrowth
Trichomoniasis Discharge
- Thin, yellow-green with possible red spots
- Often frothy with unpleasant "fishy" smell
- Caused by a parasite
Chlamydia/Gonorrhea Discharge
- Thin, cloudy or milky white/yellow
- Can have a foul smell
- Sexually transmitted bacterial infections
Testing the discharge under a microscope can identify the actual cause when the appearance resembles BV.
Getting a BV Diagnosis
If you notice any symptoms of bacterial vaginosis, it's important to see your doctor for proper testing and treatment. BV testing may involve:
- Physical exam of discharge appearance and odor
- Microscopic examination of discharge sample
- Measuring vaginal pH
- Identifying clue cells (vaginal cells coated with bacteria)
Your doctor may also test for other infections like yeast, trichomoniasis or STDs when BV is suspected.
BV Discharge Treatment
BV requires prescription antibiotic treatment. Common medications used include:
- Metronidazole (Flagyl)
- Clindamycin
- Tinidazole
These antibiotics can be taken orally or applied intravaginally. It is essential to finish the full course of antibiotics to ensure the BV is cured. Over-the-counter products marketed for BV will not be effective.
Probiotics for BV
Taking probiotic supplements containing Lactobacillus may help restore normal vaginal bacteria balance after antibiotic treatment. Probiotic suppositories may also be recommended.
Partner Treatment
If you have a male partner, he may also need antibiotic treatment to prevent reinfection. It is advised to avoid sexual intercourse until BV symptoms have resolved.
Preventing BV Recurrence
Even with successful treatment, bacterial vaginosis can recur. Ways to help prevent future BV infections include:
- Avoid douching which disrupts vaginal pH
- Use condoms to reduce exchange of bacteria during sex
- Avoid unnecessary antibiotics that kill healthy vaginal bacteria
- Wear cotton underwear and avoid tight clothes
- Use gentle, non-irritating feminine hygiene products
- Don't use scented soaps or sprays near the vagina
- Consider probiotic supplements to support vaginal health
Seeing your doctor promptly with any vaginal infection symptoms can help ensure proper diagnosis and treatment of BV or other possible causes.
