Hiatal or Paraesophageal
Hiatal hernias occur when the stomach or esophagus slide up through the diaphragm into the chest. Common symptoms are heartburn or Gastroesophageal Reflux Disease (GERD). Paraesophageal hernias occur when part of the stomach is squeezed up into the chest beside the esophagus. The stomach can be strangulated, restricting blood supply to the related tissues. Hiatal hernias may be recurrent, which means that a previously repaired hernia has returned.
People with especially weak abdominal walls or multiple surgical sites may simultaneously suffer from a combination of types of hernias.
