Eosinophilic esophagitis is a condition that mainly affects young men, who often have a history of allergies or asthma. It is an allergic reaction in the esophagus that causes difficulty swallowing food (dysphagia). The patient feels that solid foods have difficulty passing into the stomach and may experience the sensation that food is “stuck” in the chest. Episodes of food impaction are common, where food becomes lodged in the esophagus, causing intense discomfort, and in such cases swallowing saliva may become impossible.
