If you can’t swallow the food in your throat after eating, it may be caused by reflux pharyngitis, chronic pharyngitis, epiglottis cyst, esophageal cancer and so on. 1. Reflux pharyngitis: due to the reflux of stomach contents into the throat above the upper esophageal sphincter, patients often show symptoms such as throat obstruction, foreign body sensation in the throat and hoarseness due to the irritation of the mucous membrane of the throat by the refluxed material. 2. Chronic pharyngitis: chronic pharyngitis is caused by chronic inflammation of the mucosa of the pharynx, submucosa and lymphatic tissues, and patients often have the phenomenon of foreign body sensation in the throat and discomfort in swallowing. 3. Epiglottis cysts: Epiglottis cysts are caused by chronic inflammation of the larynx, mechanical stimulation or trauma, causing blockage of glands in the mucous membrane, secretions can not be discharged normally, and may also be caused by congenital developmental abnormalities. Generally speaking, for small epiglottis cysts, patients may not have any symptoms, but for large epiglottis cysts, they may cause symptoms such as foreign body sensation in the pharynx, pharyngeal obstruction, obstruction of eating, and difficulty in breathing. 4. Esophageal cancer: Patients suffering from esophageal cancer will have progressive worsening dysphagia, sometimes accompanied by obvious foreign body sensation, retrosternal pain and other symptoms. It is recommended to go to the hospital in time for relevant examinations and standardized treatment after clarifying the specific causes of the disease.
