Eosinophilic Esophagitis: Incidence and Prevalence

Eosinophilic esophagitis (EoE) is a rapidly emerging allergy-mediated condition encountered frequently in clinical practice. It presents with failure to thrive, nausea, and vomiting in children and is a common reason for dysphagia and food impaction in adults. Several institution-based and population-based studies have reported the frequency of EoE over the past few years. The incidence and prevalence of EoE vary depending on the method of data collection. In population-based studies using national registries, the incidence appears to be increasing, currently estimated to be approximately 10 cases/100,000 persons annually, whereas the prevalence is reported between 10 and 57 cases/100,000 persons.
