Causes
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.
Symptoms
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
Diagnosis
Hiatal hernias are often seen on tests for other health problems. The doctor will ask about your symptoms and health history. A physical exam may be done.
Pictures may be taken of the abdomen. This can be done with:
- Upper GI endoscopy—uses a scope with camera passed down the throat
- Upper GI series—uses X-rays and special contrast material
Treatment
Most hiatal hernias do not need treatment. The goal is to manage symptoms. Options are:
- Dietary changes, such as staying away from foods that cause heartburn
- 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.
Prevention
There are no current guidelines to prevent hiatal hernias.
