A hiatal hernia may be caused by:

  • Weakened muscles
  • An injury to the chest opening, such as a car accident
  • A buildup of pressure in the belly, such as from obesity or pregnancy
  • Recent surgery on the digestive system

Some babies are born with this problem. This is not common.

Risk Factors

Hiatal hernias are more common in older adults. Obesity also raises the risk.


Some people do not have symptoms. Those who do may have:

  • A burning feeling in the chest, especially after eating or lying down
  • Problems swallowing, such as food that comes back up
  • Pain or discomfort in the throat, chest, or stomach
  • Nausea and vomiting
  • Feeling very full after eating
  • Problems breathing
  • Burping

Most hiatal hernias do not need treatment. The goal is to manage symptoms. Options are:

  • Lifestyle changes, such as maintaining a healthy weight and not smoking
  • Medicines to control stomach acid, such as:
    • Over the counter antacids
    • H2 blockers and proton pump inhibitors (PPIs)

People with severe symptoms may need surgery. Surgery may also be needed for a hernia that is cutting off blood flow to the stomach.


There are no current guidelines to prevent hiatal hernias.
