Vaginal health can be confusing, especially when different infections have overlapping symptoms. Yeast infections and bacterial vaginosis (BV) are two of the most common vaginal conditions, yet they have distinct causes, symptoms, and treatments. Understanding the difference is key to getting the right care and preventing future occurrences.
What Causes a Yeast Infection vs. Bacterial Vaginosis BV?
-
Yeast Infection (Candidiasis):
Yeast infections are caused by an overgrowth of Candida, a type of fungus that naturally lives in the vagina. When the vaginal microbiome is disrupted—due to antibiotics, hormonal changes, or a weakened immune system—Candida can multiply and cause infection. -
Bacterial Vaginosis (BV):
BV is caused by an imbalance in vaginal bacteria. When healthy lactobacilli decrease and harmful bacteria (such as Gardnerella vaginalis) overgrow, it leads to BV. Unlike yeast infections, BV is a bacterial imbalance rather than a fungal infection (Mayo Clinic, 2023).
Key Differences in Symptoms
|
Symptom |
Yeast Infection |
Bacterial Vaginosis (BV) |
|
Discharge |
Thick, white, cottage cheese-like |
Thin, gray or white, often with a fishy odor |
|
Itching |
Intense vaginal itching |
Mild to no itching |
|
Odor |
Usually no odor |
Strong fishy smell, especially after sex |
|
Inflammation |
Redness, swelling, and irritation |
Often no redness or swelling |
While both conditions can cause vaginal discomfort, BV is more likely to cause odor, while yeast infections tend to cause intense itching and thick discharge.
How Are They Treated?
- Yeast Infection: Antifungal treatments, available over the counter or by prescription, effectively treat yeast infections. Common options include miconazole (Monistat) and fluconazole (Diflucan) (CDC, 2023).
- Bacterial Vaginosis (BV): BV requires antibiotics, such as metronidazole or clindamycin, which can be taken orally or as a vaginal gel (CDC, 2023).
Can You Prevent Yeast Infections and Bacterial Vaginosis (BV)?
Yes! The best way to prevent both conditions is to maintain a balanced vaginal microbiome:
✅ Avoid douching, which disrupts vaginal pH. CRANEL has a pH of 4 and is great at rebalancing pH.
✅ Wear breathable, cotton underwear to reduce moisture buildup.
✅ Limit antibiotic use when unnecessary, as they kill beneficial bacteria.
✅ Consume probiotics to support healthy vaginal flora. Probiotics work best when they are supported by the right environment. CRANEL helps create the perfect environment for your flora.
Additionally, cranberry polyphenols—like those in CRANEL—may help support a balanced microbiome and prevent infections by promoting good bacteria growth (Howell, 2022).
When to See a Doctor
If you’re experiencing unusual vaginal symptoms, it’s best to consult a healthcare provider for proper diagnosis. Self-treating the wrong condition can make things worse—using antifungals for BV won’t help, and antibiotics for a yeast infection could trigger further imbalances.
By understanding the difference between yeast infections and BV, you can take better control of your vaginal health and make informed choices for prevention and treatment.
