Hiatal Hernia
By Roland Larrabee, M.D.
A hiatal hernia is a condition in which part of the stomach protrudes through the diaphragm from the abdomen into the chest. The diaphragm is a thin sheet of muscle that is involved in breathing. It separates the abdomen from the chest. Hiatal hernias are common after middle age. They do not often cause problems.
The cause of hiatal hernias is not known. What is known is that they occur more often in people after middle age, in overweight people (especially women), and in smokers.
Many people with a hiatal hernia never have any symptoms. However, in some people, stomach acid and digestive juices move up into the esophagus via the bulge of the stomach through the diaphragm. This is called gastroesophageal reflux (GERD) and can cause:
-
heartburn, especially after you eat large meals or lie down
-
a bitter or sour taste in the back of your throat
-
bloating and belching
-
discomfort or pain in your stomach or esophagus
-
vomiting.
Because many hiatal hernias do not cause symptoms, they are often discovered during an investigation for other conditions. If you have symptoms, your health care provider will make the diagnosis from your medical history and a physical exam. Your provider may order other tests to confirm the diagnosis and rule out other causes of your symptoms. These tests might include:
-
upper endoscopy (examination with a viewing tube to check for signs of acid in your esophagus)
-
biopsy when undergoing upper endoscopy (to check for cancer)
-
barium x-ray (to show whether or not stomach contents are escaping into the esophagus).
Your health care provider may recommend a change in your diet. If you are overweight, you may also be given suggestions for losing weight. Your provider may prescribe medicine to buffer the acidity in your esophagus. There are two types of medicine commonly used: proton-pump inhibitors and H2 antagonists. The former require a prescription, except for over-the-counter (OTC) Prilosec®. The latter are all OTC, e.g., cimetidine (Tagamet®) and famotidine (Pepcid®. Rarely, people with hiatal hernia need surgery to control their symptoms.
