Physiologic and pathologic causes of choking need to be considered. Physiological causes include dry food, eating too fast, etc. Pathological causes include chronic pharyngitis, reflux esophagitis and esophageal cancer. 1. Physiological causes: such as over-drying of food, eating too fast, etc., can cause food not to pass through the esophagus smoothly, thus causing discomfort. 2. Pathological causes: such as chronic pharyngitis, cough, pharyngeal discomfort, etc.; such as reflux esophagitis, acid reflux, heartburn, etc.; such as esophageal cancer, progressive dysphagia, weight loss, etc.; such as pancreatic flaccidity, which is manifested as choking sensation in both fluid and solid food. For the case of always choking, it is recommended to consult a doctor to improve gastroscopy and other examinations to analyze the specific reasons.
