Hiatal Hernia Overview
Hiatal hernia is a condition in which the upper portion of the stomach protrudes into the chest cavity through an opening of the diaphragm called the esophageal hiatus. This opening usually is only large enough to accommodate the esophagus. With weakening and enlargement however, the opening (or herniation) can allow upward passage (herniation) or even entrapment of the upper stomach above the diaphragm.
