Overview

Achalasia is a disorder of the esophagus, the tube that carries food from the mouth to the stomach.[1] It is characterized by enlargement of the esophagus, impaired ability of the esophagus to push food down toward the stomach (peristalsis), and failure of the ring-shaped muscle at the bottom of the esophagus (the lower esophageal sphincter) to relax.[2] Achalasia is caused by damage to the nerves of the esophagus. Treatment is aimed at reducing the pressure at the lower esophageal sphincter and may include Botox, medications, or surgery.[1]
