achalasia
Swallowing muscle dysfunction
Achalasia is a disorder in which the esophagus fails to move food toward the stomach and the lower esophageal sphincter doesn't relax properly.
The result is difficulty swallowing, regurgitation, and chest pain.
The condition is rare and typically requires surgical intervention to widen the constricted passage.
