Feeling a grain of rice in the throat after eating may be caused by narrower esophagus, chronic pharyngitis, tumor and other causes. 1. Upper esophageal stenosis: If there is esophageal disease or congenital developmental abnormality, resulting in narrowing of the upper esophagus, if the speed of eating is faster, the rice grains may be stuck in the throat. 2. Chronic pharyngitis: the typical feature of chronic pharyngitis is the presence of foreign body sensation in the throat area, which only occurs after eating, and can be mistaken as rice grains stuck in the throat, and requires timely examination such as laryngoscopy to confirm the diagnosis. 3. Tumor: including thyroid tumor, esophageal tumor, etc., can also cause this kind of foreign body sensation, need to carry out laryngoscopy, biopsy and other tests to confirm the diagnosis. It is recommended that patients actively consult the doctor for a clear diagnosis to avoid delaying the condition.
