What is the Difference Between BV and a Yeast Infection?

BV and yeast infections are two distinct vaginal conditions with different causes and symptoms. Bacterial vaginosis occurs when the usual balance of vaginal bacteria changes, while yeast infections result from an overgrowth of Candida fungus. BV may cause a thin white or gray discharge and a fishy odor, which can be more noticeable after sex. Yeast infections often cause itching or irritation and may cause a thick, white discharge that usually has little or no odor. Symptoms can overlap, and either condition may not have all of these features. Both conditions are common. Estimates vary by population, but many people with a vagina experience BV or at least one yeast infection during their lifetime. Symptomatic BV is generally treated with antibiotics, while yeast infections are treated with antifungal medications. Because the symptoms can resemble those of other conditions, testing or medical evaluation may be needed before treatment. Proper diagnosis is essential since treatments differ significantly.
