**Abstract**

Eosinophilic esophagitis also known as asthma of the esophagus is a food-related allergic disorder of the esophagus widely distributed all over the world. The incidence and prevalence of eosinophilic esophagitis have been increasing over the last few decades. The pathogenesis of this entity is now better understood and three distinct endotypes have been defined for better management strategy. Diagnosis is made on the basis of clinical symptoms followed by endoscopy with biopsy. Drugs, diet and endoscopic dilation are the current modalities of treatment. IL-4 and IL-13 inhibitors have been found to be promising in clinical trials.
