K22 MS-DRGs

About the condition

Esophagus Disorders

Esophagus disorders are problems with how your esophagus works. The esophagus is the tube that carries food from your mouth to your stomach. You usually don't notice it unless you swallow something too big, hot, or cold. You might also notice it if something is wrong. When that happens, you might feel pain or have trouble swallowing (dysphagia).
