Overview
Eosinophilic Esophagitis (EoE) is an immune system condition of chronic esophagus inflammation, marked by an abnormal presence of eosinophils (white blood cells) in the lining of the esophagus. It can be triggered by certain foods or airborne allergens. Though sometimes confused with GERD, it is not caused by acid reflux and does not respond to acid-neutralizing therapies. Though the exact cause is unknown, the growing evidence of eosinophils playing a role in autoimmune diseases and the classification of EoE being an immunological tolerance disorder of the GI tract has led experts to think EoE may be an autoimmune disease.
