Foreign body sensation in the throat after eating may be caused by food, or it may be the manifestation symptom of certain diseases, such as reflux pharyngitis, esophageal cancer, etc., which should be consulted in time to find out the cause of the disease. 1. Food: Due to eating hard food, it may get stuck in the throat after eating, causing patients to have foreign body sensation, or hard food scratches the mucous membrane of the throat, and foreign body sensation will also occur. 2. Pathologic: (1) Patients with reflux pharyngitis will also have foreign body sensation in the pharynx, especially after meals, and gastroesophageal reflux will aggravate the symptom of foreign body sensation after eating; it is usually accompanied by reflux and heartburn. (2) Patients with esophageal cancer often have mild symptoms of local lesion irritation in the early stage, such as discomfort, burning sensation or pain behind the sternum, foreign body sensation or friction sensation locally when food passes through, and stagnant sensation or mild obstruction sensation when swallowing food. It may also be caused by other factors, such as chronic pharyngitis, but this symptom alone is not enough to diagnose the disease. It is recommended that people with persistent foreign body sensation seek prompt medical attention from a doctor to clarify the cause and give targeted treatment.
