Hiatal Hernia

(Hiatus Hernia)

Pronounced: High-AY-tal HER-nee-uh

 

Definition

A large muscle separates the belly and chest spaces. A small opening in the muscle lets the esophagus pass from the chest into the belly. There it connects to the stomach. A hiatal hernia occurs when the stomach presses up into the chest through this hole.

Different types of hiatal hernias include:

  • Sliding hiatal hernia—Part of the stomach slides into and out of the chest cavity. This is the most common type.
  • Fixed hiatal hernia—Upper part of the stomach stays in the chest cavity.
  • Several other types may be seen. They are uncommon, but more serious. May need surgery.
