Esophageal Conditions


Achalasia is an uncommon esophageal disorder primarily characterized by the failure of the lower esophageal sphincter to relax. Abnormal peristalsis ensues resulting in the impairment of the ability to push food into the stomach. If left untreated, persistent achalasia may cause the esophagus to become enlarged and eventually stop functioning. Chances of developing esophageal cancer increase for patients with untreated achalasia.
