What is a hiatal hernia?

ANSWER

Any time an internal body part pushes into an area where it doesn't belong, it's called a hernia.

The hiatus is an opening in the diaphragm -- the muscular wall separating the chest cavity from the abdomen. Normally, the esophagus (food pipe) goes through the hiatus and attaches to the stomach. If you have a hiatal hernia (also called hiatus hernia), the stomach bulges up into the chest through that opening.
