A hiatal hernia is a condition in which the upper part of the stomach bulges through an opening in the diaphragm. The diaphragm is the muscle wall that separates the stomach from the chest. The diaphragm helps keep acid from coming up into the esophagus. When you have a hiatal hernia, it's easier for the acid to come up. The leaking of acid from the stomach into the esophagus is called gastroesophageal reflux disease (GERD).
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. In a hiatal hernia (also called hiatus hernia) the stomach bulges up into the chest through that opening. There are two main types of hiatal hernias: sliding and paraesophageal (next to the esophagus).
