Frequent blockage during eating may be caused by esophageal diseases, pharyngeal diseases, or neurosis. 1. Esophageal diseases: mainly esophageal stenosis and esophageal cancer patients. Esophageal stenosis is mainly seen in repeated esophageal ulcers, corrosive esophageal burns, esophageal mucous membrane injury, formation of scar, and esophageal stenosis due to scar contraction; esophageal cancer protrudes into the lumen of the esophagus, resulting in stenosis, which can be frequent blockage sensation when eating. 2. Pharyngeal diseases: epiglottis cyst, laryngeal tumor, chronic pharyngitis and other pharyngeal diseases often cause discomfort in the pharynx, foreign body sensation, food irritation in the pharynx, and blockage sensation when eating. 3. Neurosis: common hysteria, often due to a variety of psychosomatic factors induced by self-consciousness, dysphagia, foreign body sensation in the throat, often without organic lesions. Frequent feeling of blockage when eating should go to the hospital, under the guidance of the doctor to clarify the cause and treatment.
