Description:
A hiatal hernia (say "hi-AY-tul HER-nee-uh") is different from other types of hernias. It occurs when part of your stomach bulges up through your diaphragm and into your chest. The diaphragm is a sheet of muscle that separates your belly from your chest. You can't feel a hiatal hernia or see a bulge.
