Vaginal yeast infection

Medical Education

Vaginal yeast infection, also known as candidal vulvovaginitis and vaginal thrush, is excessive growth of yeast in the vagina that results in irritation. The most common symptom is vaginal itching, which may be severe.

Vaginal yeast infections are due to excessive growth of Candida. These yeast are normally present in the vagina in small numbers. Vaginal yeast infections are typically caused by the yeast species Candida albicans. Candida albicans is a common fungus often harbored in the mouth, digestive tract, or vagina without causing adverse symptoms. The causes of excessive Candida growth are not well understood, but some predisposing factors have been identified.
