A hiatal hernia occurs when part of the stomach bulges into the chest cavity.
A hiatal hernia may allow stomach acid and juices to back up into the esophagus (acid reflux). This can cause a feeling of burning, warmth, heat, or pain behind the breastbone. This feeling may often occur after you eat, soon after you lie down, or when you bend forward, and it may come and go. You also may have a sour taste in your mouth. These symptoms are commonly known as heartburn or reflux. But not all hiatal hernias cause symptoms.
A hiatal hernia occurs when a small portion of the stomach pushes upward through the diaphragm, a sheetlike 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; nonprescription antacids, acid reducers, or acid blockers; prescription medicines; or, in severe cases, surgery.
Most people who have a hiatal hernia have no symptoms.
One symptom you may have is heartburn, which is an uncomfortable feeling of burning, warmth, or pain behind the breastbone. It is common to have heartburn at night when you are trying to sleep.
If you often have symptoms or they are severe, you may have gastroesophageal reflux disease (GERD). A hiatal hernia can lead to GERD, and people often have both conditions at the same time.
If you have pain behind your breastbone, it is important to make sure it is not caused by a problem with your heart. The burning sensation caused by GERD usually occurs after you eat. Pain from the heart usually feels like pressure, heaviness, weight, tightness, squeezing, discomfort, or a dull ache. It occurs most often after you are active.
If you have no symptoms, you don't need treatment.
If you have mild symptoms, your doctor may suggest lifestyle changes and perhaps nonprescription medicines. Here are some things to try:
If you often have symptoms or have severe symptoms, you may have GERD. Lifestyle changes may help, and your doctor may prescribe medicine. In severe cases, surgery can be used to pull the hernia back into the belly.
A hiatal hernia often is diagnosed when you see your doctor or have tests for another health problem.
If you have symptoms, your doctor will ask you questions about them. If your symptoms happen often and are severe, you may have gastroesophageal reflux disease (GERD). If this is the case, your doctor may do more tests or give you medicine for GERD.
Take medicines as prescribed. Ask your doctor what over-the-counter medicines you can take, and follow all instructions on the label. Try eating several smaller meals instead of two or three larger ones. Avoid foods that make your symptoms worse, like chocolate, mint, alcohol, and spicy foods. If you smoke, try to quit.
A hiatal hernia often is caused by weak muscles and tissue within and around the hiatus.
In a sliding hiatal hernia, a small part of the stomach pushes through the diaphragm and into the chest. A valve between the esophagus and the stomach also moves up and away from the diaphragm.
The esophagus connects to the stomach at an opening in the diaphragm called the hiatus. The lower esophageal sphincter (LES), which is normally at the same level as the diaphragm, keeps stomach contents (food, acid, and other digestive juices) from backing up (or refluxing) into the esophagus.
But when a sliding hiatal hernia is present, part of the stomach moves up through the hiatus and into the chest cavity. This pushes the lower esophageal sphincter (LES) up into the chest cavity away from the hiatus. Away from the hiatus, the LES loses the support that it needs from the diaphragm to stay closed. This raises the risk for symptoms of heartburn and gastroesophageal reflux disease.
