Giant Hiatal Hernia Esophageal Disorders

In a hiatal, or hiatus hernia, a portion of the stomach penetrates (herniates) through a weakness or tear in the hiatus of the diaphragm, the small opening that allows the esophagus to pass from the neck and chest to its connection with the stomach. Often there are no symptoms, and the condition may not cause any problems. The patient may not be aware they have a hiatal hernia.
