Achalasia occurs when your esophagus cannot contract properly, and the muscle at the end – the lower esophageal sphincter – doesn’t open and close as it should. As a result, food can’t move easily from your throat to your stomach, and you experience difficulty swallowing.

Duke gastroenterologists who specialize in esophageal disease use a series of tests to diagnose achalasia and distinguish it from other esophageal problems. They are experts in confirming which type of achalasia you are experiencing and offering effective treatment so you can find relief.
