The causes of choking on dry rice may be reflux esophagitis, pancreatic achalasia, esophageal tumors and so on. 1. Reflux esophagitis: When reflux esophagitis occurs, due to the reflux of gastric contents into the esophagus or even oropharynx, it can irritate the esophageal mucosa, resulting in acid reflux, heartburn, and intermittent gagging sensation at the back of the sternum. In severe cases, choking may also occur when eating dry food. 3. Cardia dystrophy: The loss of muscle relaxation leads to tension in the esophagus when food passes through the esophagus, causing food to stay in the upper esophagus, resulting in choking sensation. 3. Esophageal neoplastic diseases: such as esophageal cancer, esophageal tumors (e.g. smooth muscle tumors, mesenchymal tumors), etc., all of which can lead to relatively narrow lumen of the esophagus. As a result, the volume of food passing through the esophagus becomes relatively small, which leads to choking sensation. Symptoms are especially pronounced when eating certain dry foods (e.g. rice, steamed buns, etc.). If choking occurs frequently when eating and the duration of the disease is more than 1 month or more. It is recommended to go to the hospital immediately, and the cause of the disease can be clarified through gastroscopy, and the best plan for treatment can be formulated.
