Video - Eosinophilic esophagitis (NORD)

Eosinophilic esophagitis (EoE) is a rare, chronic disease that causes inflammation in the esophagus. The eosinophils are a type of white blood cell that play an important role in the immune system. In EoE, these cells accumulate in the lining of the esophagus, causing inflammation and damage. EoE is associated with other allergic diseases such as asthma. Its symptoms vary from person to person but may include difficulty swallowing (dysphagia), chest pain, nausea, vomiting, and weight loss.
