Zenker's diverticulum is a condition characterized by a pouch that can form at the junction of the hypopharynx (lower part of the throat) and the esophagus. This pouch typically causes problems by trapping food as it is being swallowed, leading to dysphagia (difficulty swallowing), regurgitation of undigested food, choking and aspiration (food particles entering the windpipe and lungs). In severe cases, surgery is required.
