[Eosinophilic esophagitis: update 2026].

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease characterized by esophageal dysfunction symptoms (dysphagia, retrosternal pain, food impaction), typical endoscopic changes, and eosinophilic infiltration of the mucosa. Since the first description of this condition more than 30 years ago, the number of diagnosed patients has significantly increased. The role of the environment in this increase and the pathogenesis are becoming increasingly well understood, although many questions remain unanswered. This article discusses the latest advances in EoE research and the currently available therapeutic options.
