Oral thrush can affect anyone but is more common in babies, the elderly, and in people with suppressed immune systems.  It is a minor problem in a healthy person but can be more severe in a person with a weakened immune system.

Oral thrush or yeast infection in a mouth can occur when a disease or drugs such as prednisone weaken your immune system.  Also, people on antibiotics may disturb the natural balance of microorganisms in the body, causing thrush.

If you have a suppressed immune system thrush is more likely to spread to your digestive tract, lungs, liver, heart..etc. The infections can also spread to the intestines, making it difficult to receive adequate nutrition.
