what is a heidel hernia
In a hiatal hernia, the stomach pushes up through that opening and into your chest. A small hiatal hernia usually doesn't cause problems. You may never know you have one unless your doctor discovers it when checking for another condition. But a large hiatal hernia can allow food and acid to back up into your esophagus, leading to heartburn. Self-care measures or medications can usually relieve these symptoms. A very large hiatal hernia might require surgery.
