Common problem: Hiatal hernias in the u..S. May be as common as 1 in 3 people. A hiatal hernia is when the junction between esophagus and stomach slips up into tbe chest from its usual place in the belly. This causes the g-e junction to stop acting as a one way valve and stomach contents (food and acid) can back up into the esophagus and even the lungs. Acid reflux, aspiration pneumonia and food sticking occur.
