Hiatal Hernia

A Hiatal Hernia occurs when the stomach bulges up into the chest through the opening in the diaphragm.

Many people with hiatal hernia have no symptoms. Some may have heartburn related to gastroesophageal reflux disease, or GERD. One condition does not seem to cause the other.

The cause of a Hiatal Hernia is unknown. Increased pressure in the abdomen such as from pregnancy, obesity, coughing, or straining during bowel movements may play a part in the cause of Hiatal Hernia.
