Pathophysiology of Hiatal HerniaA hiatal hernia occurs when part of your stomach pushes upward through your diaphragm. Yourdiaphragm normally has a small opening (hiatus) through which your food tube (esophagus)passes on its way to connect to your stomach. The stomach can push up through this opening andcause a hiatal hernia.In most cases, a small hiatal hernia doesn't cause problems, and you may never know you have ahiatal hernia 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 toheartburn. Self-care measures or medications can usually relieve these symptoms, although avery large hiatal hernia sometimes requires surgery.Most small hiatal hernias cause no signs or symptoms. However, larger hiatal hernias can causesigns and symptoms such as:HeartburnBelchingDifficulty swallowingChest or abdominal painFeeling especially full after mealsVomiting blood or passing black stools, which may indicate gastrointestinal bleedingA hiatal hernia occurs when weakened muscle tissue allows your stomach to bulge up throughyour diaphragm.
