What is EoE?
Eosinophilic Esophagitis (EoE) is an inflammatory disease of the esophagus (the tube that connects the throat and the stomach). The esophagus is made of muscles that contract to move food to the stomach. The esophagus usually does not have any eosinophils (a type of white blood cell that is present when there is an infection or inflammation). Eosinophilic esophagitis is diagnosed when high levels of eosinophils are found in the esophagus. This is thought to be caused by a response to food allergens. EoE causes a variety of symptoms including difficulty swallowing, food getting stuck in the throat, chest pain, stomach pain, and regurgitation of food or vomiting.
