Understanding Yeast Infections: Causes, Symptoms & Treatment

You do not get a yeast infection on purpose. Yeast infections are fungal infections caused by an overgrowth of Candida, a type of yeast that naturally lives in the body. Yeast infections can occur in various areas of the body, including the vagina, mouth, skin, and digestive tract. They are usually not serious and can be treated with antifungal medications.
