Infection - esophagus; Esophageal infection
Esophagitis is a term for any inflammation, irritation, or swelling of the esophagus. This is the tube that carries food and liquids from the mouth to the stomach.
Infectious esophagitis is an infection of the esophagus from viruses, bacteria, fungi, or yeast. This can occur in people with a weak immune system.
Infectious esophagitis is rare. It often occurs in people with weak immune systems. People who have strong immune systems don't usually develop the infection.
Common causes of a weakened immune system include:
Organisms (germs) that cause esophagitis include fungi, yeast, and viruses. Common organisms include:
Symptoms of infectious esophagitis include:
The health care provider will ask about your symptoms and examine your mouth and throat. Tests may include:
You may need to have an upper endoscopy exam. This is a test to examine the lining of the esophagus.
Most often, medicines can control the infection. The type of medicine given will depend on the cause of the infection.
Antiviral medicines can treat a herpes infection.
Antifungal medicines can treat candida infection.
Antiviral medicines can treat CMV infection. Ganciclovir or foscarnet are given through a vein (intravenously). In some cases, a medicine called valganciclovir, which is taken by mouth, can be used for CMV infection.
Some people may also need pain medicine.
Ask your provider for special diet recommendations. For example, there may be foods you need to avoid eating as your esophagitis heals.
Many people need other long-term medicines to suppress the virus or fungus and to prevent the infection from coming back.
In people with a healthy immune system, esophagitis often goes away on its own. People with a weak immune system may take longer to get better.
Health problems that may result from infectious esophagitis include:
Contact your provider if you have any condition that can cause reduced immune response and you develop symptoms of infectious esophagitis.
If you have a weak immune system, try to avoid contact with people who have an infection with any of the organisms mentioned above.
