Hiatal Hernia (Hiatus Hernia)
Pronounced: High-AY-tal HER-nee-uh
A hiatal hernia is a condition in which the upper part of the stomach moves up through a small opening in the diaphragm into the chest. The diaphragm is the muscular wall that separates the abdominal cavity from the chest cavity.

The different types of hiatal hernias include:
Sliding hiatal hernia—the most common type in which the herniated part of the stomach slides back and forth, into and out of the chest Fixed hiatal hernia—the upper part of the stomach permanently remains in the chest Complicated hiatal hernia—Several other types of stomach herniation may be seen. These are uncommon but more serious and may require surgery. Hiatal Hernia

Many people are born with the hiatal hernia but the cause is still unknown. It may result from a weakening of the supportive tissues.
A risk factor is something that increases your chance of getting a disease or condition.
Risk factors include:
Age: 50 or older Obesity Smoking Pregnancy Abdominal injury
Increased pressure in the abdomen from:
Severe coughing Vomiting Straining Sudden physical exertion (eg, weight-lifting)
Most people with hiatal hernias have no symptoms.
Symptoms may occur when stomach acid moves up into the esophagus (swallowing tube). This is known as
gastroesophageal reflux disease
(GERD) and can cause:
, especially after eating or lying down
Heartburn Pain or discomfort in the stomach, chest, or esophagus Belching Hoarseness Throat irritation (frequent clearing of the throat) Chest pain Difficulty swallowing Bleeding from the stomach or esophagus
Because they often have no symptoms, hiatal hernias are sometimes only detected during a visit to the doctor for other ailments. A hiatal hernia is usually diagnosed with the following tests:
—a series of
of the upper digestive system taken after drinking a barium solution, to show the outline of the digestive system.
—A camera mounted on a thin, lighted tube is inserted through the mouth into the esophagus or swallowing tube. At this time, a
or sample of tissue may be taken to check for any complications, including:
Hiatal hernias are usually treated only when there are symptoms. When GERD is present, the following measures may help:
For people who are obese, losing weight may relieve symptoms.
Avoid foods that can relax the muscle that controls the opening between the esophagus and the stomach including:
Chocolate Peppermint Fatty foods Coffee Alcoholic beverages
Avoid foods and beverages that can irritate the internal lining of the esophagus, such as:
Caffeine Citrus fruits and juices Tomato products Hot peppers Carbonated beverages
To minimize acid reflux:
Consume smaller meals 4-6 times a day versus three large meals. Avoid drinking large amounts of fluids with meals. Do not eat within 2-3 hours of bedtime.
If you smoke, quit. Smoking weakens the lower esophageal sphincter, a muscle that controls the opening between the esophagus and the stomach.
Wear clothes and belts that are loose around your waist. Avoid stooping or bending after meals, which puts increased pressure on the abdomen.
Elevating the head of the bed on 6-inch blocks or sleeping on a specially designed wedge reduces heartburn. This position helps prevent stomach contents from refluxing backward into the esophagus.
Antacids can neutralize acid and temporarily relieve heartburn.
For chronic reflux and heartburn, several types of medications may be prescribed to reduce acid in the stomach. These include:
H2 blockers such as:
Proton pump inhibitors such as:
Surgery may be needed if:
You have severe GERD symptoms that do not respond to other treatments. The hernia is at risk for twisting, which could cut off the blood supply to part of the stomach and cause that part to die.
The following strategies may help to prevent a hiatal hernia:
If you smoke, quit Seek medical care for prolonged or severe coughing or straining to pass stools or urine.
