Differentiating Eosinophilic Esophagitis and Eating/Feeding Disorders

Abstract

Eosinophilic esophagitis (EoE) is an inflammatory condition of the esophagus that causes symptoms of esophageal dysmotility. Patients with feeding or eating disorders (ED) can have similar symptoms, and there is a paucity of literature exploring these similarities. Furthermore, EoE can occur in addition to an ED, requiring clinicians to obtain a thorough history, make accurate diagnoses, and adequately treat all underlying conditions. We present 4 pediatric cases highlighting the similarities between EoE and ED symptomatology. Patients 1 to 3 were presumed to have an ED and were subsequently diagnosed with EoE. Patient 4 had a history of previously diagnosed and inadequately treated EoE, but was later found to also have a longstanding ED. The patients presented to the University of Rochester Pediatric Ambulatory Clinics in 2020. This series demonstrates that symptoms of EoE can overlap with those of an ED, such as anorexia nervosa or avoidant restrictive food intake disorder. Therefore, assessment for either EoE or an ED should include questions related to both diagnoses. Symptoms that may raise suspicion of EoE are indigestion, acute (versus chronic) weight loss, and dysphagia, including the inability to swallow pills, particularly in the presence of personal or family history of atopy. Patients with known EoE should be periodically evaluated for the presence of an ED. This case series illustrates that EoE can either present as an ED or complicate the diagnosis and/or treatment of an ED, making prompt diagnosis and treatment essential for successful management of all conditions.
