A yeast infection, also called candidiasis, is a fungal infection that can affect the skin, mouth, throat, genitals, or other parts of the body. Yeast infections are caused by a type of fungus called Candida.
Yeast infections are common, especially in women. They can be uncomfortable and irritating, but they are usually not serious. However, if a yeast infection is left untreated, it can lead to more serious health problems.
