Vaginal yeast infections and BV are both types of vaginitis, which is the general name for inflammation of the vagina or vulva. BV is the most common type of vaginitis, followed by vaginal yeast infections, then trichomoniasis (also known as trich).
Vaginal yeast infections and BV have some overlapping symptoms, like itchiness and discomfort, but BV is associated with a fishy odor, while yeast discharge is odorless. BV discharge also tends to be thin, grayish, or foamy, while yeast infection discharge tends to be thick, white, or like cottage cheese.
You're in the right place to get vaginal yeast infection treatment. If you think you have BV or trich, you'll need to see a trusted healthcare provider for lab testing.
