Hiatal hernia Open pop-up dialog box Close Hiatal hernia Hiatal hernia A hiatal hernia occurs when the upper part of your stomach bulges through your diaphragm into your chest cavity. A hiatal hernia occurs when the upper part of your stomach bulges through the large muscle separating your abdomen and chest diaphragm. Your diaphragm has a small opening hiatus through which your food tube esophagus passes before connecting to your stomach.
In a hiatal hernia, the stomach pushes up through that opening and into your chest. You may never know you have one unless your doctor discovers it when checking for another condition.

A very large hiatal hernia might require surgery. Symptoms Most small hiatal hernias cause no signs or symptoms. But larger hiatal hernias can cause: Heartburn Regurgitation of food or liquids into the mouth Backflow of stomach acid into the esophagus acid reflux Difficulty swallowing.
