What is Hiatus Hernia?

A hiatus hernia occurs when part of the stomach pushes up through the diaphragm into the chest cavity, which can allow stomach acid to reflux more easily into the oesophagus, causing symptoms like heartburn and regurgitation. Many people with a hiatus hernia have no symptoms at all, and it's often found incidentally during tests for other reasons.

When it does cause symptoms, treatment usually focuses on managing the associated acid reflux with lifestyle changes and medication, with surgery reserved for more severe or persistent cases that don't respond to other treatment.
