What to Know About Hiatal Hernia

Medically Reviewed By Saurabh Sethi, M.D., MPH

Hiatal hernia is a condition in which a portion of the stomach pushes up through the diaphragm. Most people do not have any symptoms. Doctors may find the hernia during testing for another reason. Treatment is not necessary if there are no hiatal hernia symptoms or complications. Sometimes, a large hiatal hernia causes symptoms. These can include heartburn, indigestion, or a burning feeling in the upper belly or chest. These hernias are treatable with medicine or sometimes surgery.

Symptoms that might indicate a serious or life threatening condition

In rare cases, hiatal hernia can result in serious complications. This includes a strangulated hernia or esophageal ulcers. Seek immediate medical care (call 911) for the following symptoms:

With a hiatal hernia, the stomach is able to go up through the hiatus, an opening in the diaphragm. The hiatus is a sheet of muscle that separates the chest from the abdomen. A typical hiatus lets the esophagus transfer swallowed food to the stomach. It does not allow the stomach to push up through it.

Often, a hiatal hernia is not a serious condition. In fact, less than 10% Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source  of people with the condition have symptoms. Doctors recommend treating hiatal hernias that cause symptoms. 

Hiatal hernia complications are rare. However, hiatal hernia may occur with gastroesophageal reflux disease (GERD). This can lead to complications such as ulcers in the esophagus and bleeding in the digestive tract. 

Seek prompt medical care if you have hiatal hernia symptoms. Early diagnosis and treatment can reduce discomfort and the risk of complications. 

Chest pain can be a symptom of hiatal hernia. However, it can also indicate a heart attack. Call 911 for chest pain that has not been previously evaluated for possible heart attack. Other serious symptoms that warrant immediate medical care include vomiting blood.

Symptoms of hiatal hernia

Hiatal hernia symptoms can vary in nature and severity between people. Most people have no symptoms or complications. When symptoms occur, they often relate to acid reflux into the esophagus due to GERD. Symptoms can range in severity from mild to severe and include:

Types of hiatal hernia 

There are two main types Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source of hiatal hernias:

  • Sliding hiatal hernia: In this type, the junction of the esophagus and stomach and some of the stomach right below this junction slide up through the diaphragm. This is the most common type of hiatal hernia. It accounts for more than 95% of cases. 
  • Paraesophageal hiatal hernia (PEH): This type involves the stomach fundus. The fundus is the upper curved portion of the stomach. In PEH, part of the fundus sticks up through the diaphragm and sits beside the esophagus. The junction of the esophagus and stomach may or may not also slide through the diaphragm.

What causes hiatal hernia?

Muscle weakness or loss of flexibility in the diaphragm may play a role. A 2021 article explains Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source that some cases of hiatal hernia are the result of injury due to increased abdominal pressure. This could occur with heavy lifting or violent coughing, straining, or vomiting. It is possible for babies to be born with a hiatal hernia as well. This birth defect is called congenital diaphragmatic hernia.

Hiatal hernia risk factors

A number of factors increase the chance of developing a hiatal hernia. Not all people with risk factors will develop the condition. Factors Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source  linked to hiatal hernia include:

Preventing hiatal hernia

Preventing a disease or condition often relies on changing risk factors that you can control. You may be able to lower your chance of developing a hiatal hernia or complications of one by:

  • maintaining a moderate weight
  • not smoking
  • practicing stress reduction techniques
  • treating conditions associated with hiatal hernia, such as COPD

What are the diet and nutrition tips for hiatal hernia? 

If a hiatal hernia causes symptoms, it may help to avoid foods that trigger them. This means limiting or eliminating the following:

  • alcohol, caffeine, and carbonated or acidic beverages
  • chocolate and mint
  • citrus fruit
  • fatty or fried foods
  • garlic and onion
  • tomato sauce, ketchup, mustard, and vinegar

Ask your doctor for guidance before making significant changes to your diet.

What are some conditions related to hiatal hernia? 

GERD is a condition closely related to hiatal hernia. The symptoms of the two conditions overlap. In addition, it is common Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source  to have both conditions. However, it is possible to have one and not the other, so they do not necessarily cause one another. Rather, it is likely that having a hiatal hernia increases the chances of having GERD.  

Hiatal hernia diagnosis

To diagnose your condition, your doctor will take a medical history and possibly order testing. A physical exam and feeling your abdomen is unlikely to help with the diagnosis. However, your doctor may feel for lymph nodes around your neck and listen to your heart and lungs. 

Questions your doctor may ask include:

  • What symptoms are you experiencing?
  • When did your symptoms start?
  • Are your symptoms constant or do they come and go?
  • How severe are your symptoms? Do they disrupt your daily life?
  • What, if anything, seems to make your symptoms better or worse?
  • What other medical conditions do you have?
  • What medications do you take?

Tests and procedures for diagnosing hiatal hernia Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source  include:

  • barium swallow
  • CT scan
  • esophageal manometry, which evaluates your esophageal muscles when you swallow
  • pH testing, which evaluates acid reflux
  • upper endoscopy

Hiatal hernias without symptoms often show up when doctors use these tests to diagnose other problems.

Can you fix a hiatal hernia yourself?

Hiatal hernia treatment often involves medication, surgery, or lifestyle changes. There are anecdotal stories that this at-home protocol may help push the stomach back down through the diaphragm:

  • Drink a glass of warm water first thing in the morning.
  • Stand on your tip toes and then drop down to your heels quickly — enough for a good jolt. Do this 10 to 15 times.
  • Finally, raise your arms up in the air and take short quick breaths through your mouth for 15 seconds.

Note: These steps are not backed by scientific evidence or studies. Before you try this method, talk with your healthcare professional for guidance.

Hiatal hernia treatment options 

Hiatal hernia treatment aims to improve symptoms and reduce the risk of complications. Treatment depends on several factors. These include the severity of your symptoms, the type of hiatal hernia, the presence of other diseases, and your age and medical history.

Hiatal hernia treatment includes:

  • avoiding large meals and instead eating several small meals throughout the day
  • elevating the head during sleep to prevent acid reflux
  • medications, including over-the-counter antacids, such as Tums, Tagamet, or Pepcid
  • reducing alcohol, coffee, or acidic beverages and other dietary changes
  • not eating late at night or up to 2 hours before bedtime
  • not smoking
  • participating in a regular exercise routine to maintain a moderate weight
  • wearing loose-fitting clothing to minimize pressure and constriction of the abdomen

For hiatal hernia with GERD, drug treatment may include:

  • H2 blockers, which reduce stomach acid
  • proton pump inhibitors (PPIs), which decrease the production of stomach acid

For people with a chance of complications from the hernia, surgery may be necessary. After pushing the stomach below the diaphragm, the surgeon will suture a mesh plug over the opening or use sutures to strengthen the area.

What to ask your doctor about hernia surgery.

What are the potential complications of hiatal hernia?

Complications of hiatal hernia can be serious but are not common. They include obstructed hiatal hernia and strangulated hiatal hernia. A strangulated hernia cuts off blood supply to the stomach. It is a medical emergency.

When GERD is also present, acidic stomach contents back flow into the esophagus. With time, this can damage the esophagus and lead to the following conditions:

  • Barrett’s esophagus, a condition that increases the chance of developing esophageal cancer
  • chronic difficulty swallowing
  • esophageal bleeding
  • esophageal ulcers 
  • esophagitis
  • scarring of the esophagus

Other frequently asked questions

Here are a few commonly asked questions about hiatal hernia. The answers have been medically reviewed by Dr. Saurabh Sethi.

What does a hiatal hernia attack feel like?

Many people with a hiatal hernia do not have symptoms. However, when symptoms do manifest, they are often linked to acid reflux. You may experience heartburn, indigestion, nausea, or vomiting. 

How can you fix a hiatal hernia yourself?

Treatment for a hiatal hernia typically involves lifestyle and diet changes, medications to treat GERD, or surgery. You should discuss any at-home treatments or exercises with your doctor first.

How serious is a hiatal hernia?

A hiatal hernia is rarely serious, and you may not have any symptoms at all. However, hiatal hernias can lead to a strangulated hernia or esophageal ulcers. If you are experiencing difficulty swallowing, sudden or severe abdominal or chest pain, or bloody vomiting, seek immediate medical care.

Does omeprazole help with hiatal hernia?

Omeprazole can help relieve the symptoms of a hiatal hernia that occur with GERD. Omeprazole is a PPI, which means that it reduces the amount of stomach acid your body produces.


A hiatal hernia is a common condition that usually does not cause symptoms. If you have one that causes discomfort or acid reflux, treatments are available. Options include medicines to manage symptoms and surgery. Complications of hiatal hernia are rare.
