Protrusion of part of the stomach through the hiatus of the diaphragm (see hiatus).

A condition in which part of the stomach slides up through the diaphragm into the chest cavity. Although usually symptomless–when symptoms do occur they are usually due to a weak lower esophageal sphincter (LES) causing heartburn and not to the hiatal hernia itself.

Herniation of a part of the stomach through the oesophageal hiatus, often causing heartburn

The term which describes abnormal mobility of the stomach allowing the junction with the gullet to pass through the opening in the diaphragm into the chest cavity. As a result, the mechanism normally preventing regurgitation of stomach contents into the oesophagus fails, and acid moves up the oesophagus damaging the lining (reflux oesophagitis) and causing burning pain. The hernia may resolve spontaneously and is often present without abnormal acid reflux.

Protrusion of part of stomach through diaphragm at oesophageal entrance.

Hiatus hernia or hiatal hernia is the protrusion (or herniation) of the upper part of the stomach into the thorax through a tear or weakness in the diaphragm.
