Complications

By Mayo Clinic staff

Oral thrush is seldom a problem for healthy children and adults, although the infection may return even after it's been treated. For people with compromised immune systems, however, thrush can be more serious.

If you have HIV, you may have especially severe symptoms in your mouth or esophagus, which can make eating painful and difficult. If the infection spreads to the intestines, it becomes difficult to receive adequate nutrition. In addition, thrush is more likely to spread to other parts of the body if you have cancer or other conditions that weaken the immune system. In that case, the areas most likely to be affected include the digestive tract, lungs and liver.
