Obstruction in swallowing may be caused by luminal narrowing, pharyngeal dyskinesia, esophageal dyskinesia, etc. Prompt medical consultation is recommended. 1. Luminal stenosis: such as esophageal tumors (smooth muscle tumor, hemangioma, polyp, esophageal cancer, etc.), oropharyngeal infections (tonsillitis, pharyngeal tuberculosis, etc.), esophageal inflammation (reflux esophagitis, esophageal tuberculosis, etc.), and extrinsic pressure stenosis (extreme enlargement of thyroid gland, mediastinal tumors, abscesses of posterior pharyngeal wall, etc.). 2. Pharyngeal dyskinesia: such as oropharyngeal muscle paralysis, dry syndrome, etc. Patients may also have choking on drinking water, dry mouth and other symptoms. 3. Esophageal dyskinesia: such as esophageal spasm, pancreatic achalasia, etc. Patients may also have chest pain, regurgitation, heartburn and other symptoms. 4. Others: such as foreign body in the esophagus, anxiety disorder, depression, etc., may also have the symptom of obstructive sensation when swallowing. If the patient has obstruction when swallowing, persists without relief or is accompanied by other discomforts, he/she should consult a doctor in time to find out the cause of the disease under the doctor’s guidance, and carry out the corresponding treatment if necessary.
