Paraesophageal Hernia

Causes of Paraesophageal Hernia

While paraesophageal hernia research continues to bring clarity to this condition, the causes of paraesophageal hernia are not fully known.

Doctors have made a connection between gastroesophageal reflux disease (GERD) because many patients with paraesophageal hernia also have GERD. On the other hand, many times the conditions occur separately and therefore may not be related.

While some causes are not certain, doctors have noted these paraesophageal hernia causes:

  • A large hiatal opening from birth
  • A weakness in the wall of the abdomen from birth
  • Pregnancy or obesity puts extra weight on the abdomen
  • Heavy coughing or straining during bowel movements also increase pressure
  • Aging
  • Previous surgery

Of those diagnosed with hiatal hernia, only half experience any symptoms of paraesophageal hernia, and it is usually mild heartburn. Regardless of the causes of paraesophageal hernia, surgery is usually the best treatment option when the hernia begins to cause pain.
