PREVIEW
A hiatal hernia is when your stomach bulges up into your chest through an opening in your diaphragm, the muscle that separates the two areas. The opening is called the hiatus, so this condition is also called a hiatus hernia.
There are two main types of hiatal hernias: sliding and paraesophageal.
Ordinarily, your esophagus (food pipe) goes through the hiatus and attaches to your stomach. In a sliding hiatal hernia, your stomach and the lower part of your esophagus slide up into your chest through the diaphragm. Most people with hiatal hernias have this type.
A paraesophageal hernia is more dangerous. Your esophagus and stomach stay where they should be, but part of your stomach squeezes through the hiatus to sit next to your esophagus. Your stomach can become squeezed and lose its blood supply. Your doctor might call this a strangulated hernia.
