Swallowing is normal when eating, but it is difficult to swallow when eating buns. This condition is considered to be choking when eating dry food, and it may be dry syndrome, reflux esophagitis, esophageal space occupation and other diseases. 1. Dry syndrome: patients with dry syndrome have reduced secretion of glands in all parts of the body, with dryness of the mouth and eyes as the main symptom, and in severe cases, they need to drink water frequently when speaking, and when eating solid food, they have to be accompanied by water or fluids, which causes obstruction of swallowing when eating buns. Atrophic gastritis, decreased gastric acid, dyspepsia and other manifestations can also occur. 2. Reflux esophagitis: Reflux esophagitis can lead to esophageal mucosal damage, the typical symptoms are acid reflux, heartburn, but the serious cases can also appear in solid food choking, unimpeded feeling. Patients need to use acid-suppressing agents and gastrointestinal mucosal protectants under the guidance of doctors, and consider endoscopic and surgical treatment if necessary. 3. Esophageal occupation: it may be benign tumor or malignant esophageal cancer, both cases will present with dysphagia. Barium esophageal examination and esophageal fiberoptic endoscopy are helpful for diagnosis and differentiation. For both benign and malignant tumors of the esophagus, surgical resection is the main treatment of choice when the patient’s general condition permits. If prolonged dysphagia occurs, please seek medical attention immediately.
