What is Zenker's Diverticulum?
An abnormal, pouch-like structure that forms where the pharynx and esophagus meet. Swallowing requires a complex coordination of muscles in the mouth, pharynx and esophagus. If one or more of these muscles isn’t working properly, pressure can build up and cause a weak part of the pharynx wall to balloon out. Over time, the pouch can grow large enough to collect swallowed foods.
What causes Zenker's Diverticulum?
Acid reflux and advanced age likely play a role in Zenker’s. Symptoms may include difficulty swallowing, regurgitation, bad breath, hoarseness, persistent cough and more. Some people find they must resort to special maneuvers to empty the pouch, like turning their head and pressing a specific spot on the neck. If left untreated, symptoms can get worse with time.
