Thrush is an infection of the mouth caused by the candida fungus, also known as yeast. Candida infection is not limited to the mouth; it can occur in other parts of the body as well, causing diaper rash in infants or vaginal yeast infections in women.
Thrush usually develops suddenly, but it may become chronic, persisting over a long period of time. A common sign of thrush is the presence of creamy white, slightly raised lesions in your mouth—usually on your tongue or inner cheeks—but also sometimes on the roof of your mouth, gums, tonsils, or back of your throat. The lesions, which may have a "cottage cheese" appearance, can be painful and may bleed slightly when you scrape them or brush your teeth. In severe cases, the lesions may spread into your esophagus, or swallowing tube, causing:
- Pain or difficulty swallowing
- A feeling that food gets stuck in the throat or mid-chest area
- Fever, if the infection spreads beyond the esophagus
Small amounts of the candida fungus are present in the mouth, digestive tract, and skin of most healthy people and are normally kept in check by other bacteria and microorganisms in the body. However, certain illnesses, stress, or medications can disturb the delicate balance, causing the fungus candida to grow out of control, causing thrush.
Medications that upset the balance of microorganisms in the mouth and may cause thrush include corticosteroids, antibiotics, and birth control pills.
