Achalasia is a rare disorder of the esophagus that affects the ability of the esophagus to move food toward the stomach. It may occur at any age, but is typically more common in middle-aged and older persons. It may be inherited, as well. When people have achalasia, the muscles in their esophagus and the valve that allows food to pass into and remain in the stomach do not work properly.
Because achalasia is a difficult condition to diagnose and is often mismanaged, many believe it is best diagnosed and treated by doctors who specialize in treating it. Esophageal cancer and stomach cancer, as well as Chagas disease may cause symptoms similar to achalasia. Learn more . . .
