Eosinophilic esophagitis (EoE) is a chronic disorder of the digestive system in which large numbers of a particular type of white blood cell called eosinophils are present in the esophagus. The esophagus is the tube that carries food from the mouth to the stomach. Eosinophils are an important part of the immune system and play a role in immune regulation and fighting certain infection, and their accumulation is a hallmark of allergic diseases. This condition is characterized by vomiting, stomach or chest pain, failure to thrive (particularly in children), difficulty swallowing, and food getting stuck in the throat.
