A hiatal hernia is a condition in which the upper part of the stomach moves up through a small opening in the diaphragm into the chest. The diaphragm is the muscular wall that separates the abdominal cavity from the chest cavity.

The different types of hiatal hernias include:
- Sliding hiatal hernia—the most common type in which the herniated part of the stomach slides back and forth, into and out of the chest
- Fixed hiatal hernia—the upper part of the stomach permanently remains in the chest
- Complicated hiatal hernia—Several other types of stomach herniation may be seen. These are uncommon but more serious and may require surgery.
