| hiatal hernia | <gastroenterology, surgery> A type of hernia that occurs when a portion of the stomach protrudes through the diaphragm (where the oesophagus normally passes through). Obesity and smoking are considered risk factors. Hiatal hernia is often associated with reflux oesophagitis. Symptoms include heartburn, difficulty swallowing, chest pain and belching. Treatment includes H2 antagonists, antacids and medications which strengthen the lower oesophageal sphincter. (27 Sep 1997) |

| hiatal hernia |
A small opening in the diaphragm allows for the upper portion of the stomach to move backwards into the chest. This is a dynamic condition with the upper stomach changing its position between the upper stomach and lower chest. This is associated with gastroesophageal reflux disease, heartburn and epigastric abdominal pain.
