Definition
Hiatal hernia is a condition in which a portion of the stomach protrudes upward into the chest, through an opening in the diaphragm. The diaphragm is the sheet of muscle that separates the chest from the abdomen. It is used in breathing.
Symptoms
A hiatal hernia by itself rarely causes symptoms -- pain and discomfort are usually due to the reflux of gastric acid, air, or bile. Reflux happens more easily in the presence of hiatal hernia, though a hiatal hernia is not the only cause of reflux..

Causes
The cause is unknown, but hiatal hernias may be the result of a weakening of the supporting tissue. Increasing age, obesity , and smoking are known risk factors in adults.
Children with this condition usually have it from birth (congenital). It is usually associated with gastroesophageal reflux in infants.
Hiatal hernias are very common, especially in people over 50 years old. This condition may cause reflux (backflow) of gastric acid from the stomach into the esophagus.
Treatment
The goals of treatment are to relieve symptoms and prevent complications.
Reducing the backflow of stomach contents into the esophagus (gastroesophageal reflux) will relieve pain symptoms. Medications that neutralize stomach acidity, decrease acid production, or strengthen the lower esophageal sphincter may be prescribed.
Other measures to reduce symptoms include:
- Avoiding large or heavy meals
- Not lying down or bending over immediately after a meal
- Reducing weight and not smoking
Failure to control the symptoms by general or medical measures, or the appearance of complications, may require surgical repair of the hernia.

Outlook (Prognosis)
Most symptoms are alleviated with treatment.
Prevention
Controlling risk factors like obesity may play a preventative role.
