The eosinophil is a type of white blood cell that is normally found in the body but not in the esophagus (the tube that connects your mouth to your stomach). Until the 2000s, doctor were really looking for the eosinophil in the esophagus and did not have the diagnosis of Eosinophilic Esophagitis (E0E). EoE is the presence of eosinophils in the esophagus where they can cause the tissue in the esophagus to become sticky, scar down, and narrow. It does not cause cancer, but does cause troublesome symptoms including food sticking. An upper endoscopy is a procedure where a doctor uses a special tube called a scope with a camera on the tip to look down your esophagus to notice this narrowing and scarring to diagnose EoE. Treatment options include acid-blocking medications, swallowed topical steroids, and dietary restrictions.
