What Is an Esophageal Stricture?

An esophageal stricture is a narrowing of the esophagus (the muscular tube connecting the mouth to the stomach) that makes it difficult to swallow. Esophageal strictures can be benign (noncancerous) or caused by esophageal cancer.

Regardless of the cause of the stricture, complications can include weight loss, malnutrition, choking and aspiration pneumonia.
