hiatal hernia

a hiatal hernia occurs when a small portion of the stomach pushes upward through the diaphragm, a sheet-like muscle that separates the lungs from the abdomen. usually this doesn't cause any symptoms, but it increases the risk of stomach acid backing up into the esophagus (reflux), which can lead to heartburn.

normally the entire stomach sits below the diaphragm. the esophagus passes through an opening in the diaphragm called the hiatus before it enters the stomach. weakened tissues within and around the hiatus allow a hiatal hernia to develop.

a hiatal hernia that is not causing symptoms does not usually need any treatment. treatment for a hiatal hernia that causes heartburn is the same as for gastroesophageal reflux disease (gerd). this may include home treatment with lifestyle changes; non-prescription antacids, acid reducers, or acid blockers; prescription medicines; or, in severe cases, surgery.
