    • Achalasia is a disorder in which the lower esophageal sphincter does not relax when food passes down the esophagus to the stomach. As a result, the esophagus becomes distended and filled with food, and food passes into the stomach very slowly. Achalasia is often associated with chest pain during eating, weight loss, and regurgitation of food. The lower esophagus becomes distended as food and liquid are unable to pass into the stomach.
