What Is Esophagus Disorders?

What are 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). What causes esophagus disorders? The cause depends on the type of disorder. Some run in families. Others are linked to allergic reactions to food or substances in your environment. Sometimes, the cause is unknown.
