An eosinophilic esophagitis diagnosis is often delayed because of a lack of awareness around this condition. When patients report symptoms that are consistent with EoE, a doctor will perform a procedure called upper endoscopy. During this procedure, a small tube is inserted through the mouth into the esophagus and small tissue samples are removed (biopsy). The biopsies are examined for an eosinophil count to determine if there are abnormal number of eosinophils in the esophagus. Diagnosis is typically determined by both an allergist and gastroenterologist.

There are currently no medications known to cure eosinophilic esophagitis. Some medications may suppress eosinophil levels or alleviate symptoms. Determining a treatment plan requires working with an allergist and gastroenterologist. Treatments include steroids, proton pump inhibitors, and diet modification (most commonly milk, egg, soy, wheat, nuts and fish). Endoscopies and biopsies are typically needed to determine the effectiveness of a treatment. With proper and ongoing care people with EoE can manage their condition.
