Reflux esophagitis: Reflux of gastric contents due to decrease in anti-reflux function, decrease in esophageal clearance ability, abnormal sensation in esophagus, delayed gastric emptying, etc. can cause difficulty in swallowing and choking while eating. 2. Esophageal cancer: Esophageal cancer is a malignant tumor of epithelial origin in the esophagus, which mainly manifests symptoms such as choking while eating, foreign body sensation, retrosternal pain or obvious difficulty in swallowing. 3.
