Hiatal Hernia

Hiatal Hernia

What is known as a hiatal hernia can attack the digestive system in the diaphragm with an opening where the esophagus and the stomach meet. When the stomach applies pressure to the gap near the diaphragm it causes a hiatal hernia.

This hernia can be either very large or very small and the severity can range from harmless to extreme pain, most commonly: heartburn, belching, chest pain and nausea.

What causes hiatal hernias is unknown but doctors believe that pressure on the abdomen may increase the chance of developing this condition especially if a patient has sustained an injury to the abdominal region of the body.
