Hiatal hernia is a condition in which part of the stomach extends through an opening the diaphragm into the chest. The diaphragm is the sheet of muscle that divides the chest from the abdomen.
The exact cause of hiatal hernias is unknown. The condition may be due to a weakening of the supporting tissue. Your risk for the problem goes up with age, obesity, and smoking. Hiatal hernias are very common. The problem occurs often in people over 50 years old.
This condition may cause reflux (backflow) of gastric acid from the stomach into the esophagus.
Children with this condition are usually born with it (congenital). It often occurs with gastroesophageal reflux in infants.
A hiatal hernia by itself rarely causes symptoms. Pain and discomfort are due to the upward flow of stomach acid, air, or bile.
The goals of treatment are to relieve symptoms and prevent complications. Treatments may include:
Other measures to reduce symptoms include:
If medicines and lifestyle measures do not help control symptoms, you may need surgery.
Treatment can relieve most symptoms of hiatal hernia.
Call your health care provider if:
Controlling risk factors such as obesity may help prevent hiatal hernia.
