A yeast infection, also referred to as candidiasis or a thrush, is a common fungal infection caused by an overgrowth of the Candida (yeast) species in certain areas of the body such as the mouth, vagina, digestive tract, lungs, liver or skin. These types of infections typically occur when there is an alteration of bacteria which are responsible for controlling and limiting yeast production. This variation may be triggered by the use of oral contraceptives (due to an increase in estrogen levels), antibiotics, corticosteroids (steroids), and cancer treatments, specifically chemotherapy. Other causes of a yeast infection may include pregnancy, human immunodeficiency virus, hormonal therapies, or diabetes.

Yeast infections may be treated through over-the-counter products such as suppositories, fungal creams to apply to the area, or antifungal medications. Persistent or recurring yeast infections should be examined by a healthcare professional to determine the cause and prevent further imbalances.
