Eosinophilic Esophagitis is a Chronic Disease of the Esophagus

Eosinophilic esophagitis is a chronic, immune-mediated progressive disease of the esophagus, characterized by eosinophilic infiltration and clinical symptoms of esophageal dysfunction.Nutritional allergens play a dominant role in mediating the immune reaction.The esophagus of an adult is about 25 cm long and about 2.5 cm in diameter.It connects the mouth to the stomach and transports food, which means that the lining of the esophagus comes into contact with everything that is ingested as food and drink.The causes of eosinophilic esophagitis are thought to involve a number of factors, including a chronic inflammatory reaction to certain foods and airborne allergens.
