Types of hiatus hernia
There are two main types of hiatus hernia: Sliding hiatus hernia (most common) Paraesophageal hiatus hernia In asliding hiatus hernia,the junction between the esophagus and the stomach as well as a portion of the stomach itself, all of which are normally below the diaphragm, bulge above it. More than 40% of people in the United States have a sliding hiatus hernia and the frequency increases in people older than 60. In aparaesophageal hiatus hernia,the junction between the esophagus and stomach is in its normal place below the diaphragm, but a portion of the stomach is pushed above the diaphragm and lies beside the esophagus. A hiatus hernia is an abnormal bulging of a portion of the stomach through the diaphragm.
