What Is a Hiatal Hernia?

This common problem occurs when part of the stomach slides up through the diaphragm into the chest cavity. Hiatal hernias aren’t like hernias in your groin. Most hiatal hernias cause no symptoms and need no treatment. If you notice symptoms, usually you can control them easily.
What You May Feel
Most people with hiatal hernias have no symptoms. But if reflux (acid backup) occurs, you may notice the following:
Heartburn or other chest discomfort
Frequent burping
Acid taste in the mouth
Problems swallowing
Nighttime choking, coughing, or wheezing
Treating Symptoms 
the hiatus is a hole in the diaphragm. The esophagus passes through this hole into the stomach. If the hiatus is wide, part of the stomach may bulge above the diaphragm. This bulge is called a hernia. Stomach acid may move up into the esophagus and cause symptoms.

When you eat, the muscle at the hiatus relaxes to allow food to pass into the stomach. It tightens again to keep food and digestive acids in the stomach.
If you have been diagnosed with hiatal hernia, these suggestions may help improve symptoms:
Lose excess weight. Excess weight puts pressure on the stomach and esophagus.
Avoid cigarettes, alcohol, fatty foods, chocolate, coffee, peppermint, and spearmint.
Avoid anything that causes symptoms. Stay away from any food or drink that gives you problems. Many medications can cause symptoms. Discuss your medications with your health care provider.
Try acid-reducing medications. Over-the-counter antacids may relieve heartburn. Talk to your health care provider about these other over-the-counter or prescription medications may also help.
Surgery is usually needed only for severe symptoms or when other options have not helped the condition. Your health care provider will help you determine if surgery is an option for you.
