Three out of four women will experience at least one yeast infection in their lifetimes. If you’ve had one, you know the signs: severe vaginal itching and irritation accompanied by a thick, white discharge. Sometimes you might feel a burning sensation during urination or sex. Yeast infections certainly aren’t pleasant, but under most circumstances, they’re easy to treat.
A vaginal yeast infection, which is also sometimes called vulvovaginal candidiasis, happens when the healthy yeast that normally lives in your vagina grows out of control. It often leads to itching and other irritating symptoms. The medical name for a yeast infection is "candidiasis," because they’re usually caused by a type of yeast called candida.
