What is eosinophilic esophagitis? Eosinophilic (ee-oh-sin-oh-fill-ick) esophagitis (EE for short) is an allergic reaction in the esophagus, the tube that carries food from the mouth to the stomach. The foods that trigger EE vary from person to person.

During an allergic reaction, various cells congregate and cause symptoms like redness, swelling and itchiness. A white blood cell called an eosinophil (ee-oh-sin-oh-fill) is one of the types of cells behind an allergic reaction. Eosinophils are an important part of the immune system and there are always small quantities in the blood and intestine fighting parasites and performing other duties. However, eosinophils cause problems when they appear in high quantities in areas other than the blood and intestine. If you have seasonal allergies, eosinophils are in your nose; if you have asthma, they are in your lungs; and if you have EE, they are in your esophagus.

The suffix "-itis" means inflammation. So eosinophilic esophagitis means an inflammation of the esophagus caused by eosinophils. The disease is commonly called EE but you may also hear it referred to as EoE.
