Do you often experience a burning sensation in your chest? Do you frequently get an acidic or sour taste in your mouth after eating, or sometimes feel as if food is coming back up? Perhaps you have difficulty swallowing or feel like there is a lump stuck in your throat. While these are symptoms many of us tend to brush off, they could be signs of a condition called a "Hiatal Hernia." Don't worry—this is a very common condition that is effectively treatable. Let's discuss it in detail, just like we would in a friendly, professional consultation at Nirogi Lanka.
What is a Hiatal Hernia?
Simply put, a hiatal hernia occurs when the upper part of your stomach pushes up into your chest cavity through a small opening in your diaphragm—the large muscle that separates your chest from your abdomen. Think of your diaphragm as a wall. This wall has a small opening (esophageal hiatus) that allows your esophagus to connect to your stomach. If this opening becomes too wide or weakened, part of your stomach can bulge upward. That bulge is what we call a hiatal hernia.
A hernia occurs when an organ or tissue squeezes through a weak spot in the muscle or tissue barrier that usually holds it in place. Hernias are common, and hiatal hernias are seen in a significant number of people. They typically develop gradually over several years, rather than happening all at once.
What are the types of Hiatal Hernias?
There are two main types: sliding hiatal hernia and paraesophageal hiatal hernia. The sliding type is by far the most common.
- Type 1: Sliding Hiatal Hernia
This is the most common type (about 95% of cases). In this instance, the junction where your esophagus meets your stomach slides up through the opening in your diaphragm and then moves back down. Because it "slides" back and forth, it is called a sliding hernia.
- Type 2: Paraesophageal Hiatal Hernia – also known as a Rolling Hiatal Hernia.
In this type, a portion of the upper stomach pushes up through the diaphragm opening but stays next to the esophagus. It can often look like a localized bulge or a ball-like protrusion.
- Type 3: Mixed Hernia
This is a combination of the two types mentioned above. Both the junction where the esophagus meets the stomach and another part of the stomach move upward into the chest cavity.
- Type 4: Complex Hernia
This is rarer and more complex. It occurs when the opening in the diaphragm is significantly enlarged, allowing not just the stomach, but other abdominal organs—such as a section of the colon, the pancreas, or the spleen—to move upward.
How common are Hiatal Hernias?
They are actually much more common than you might think, especially as you age. Research suggests about 20% of the general population may have one. By the age of 50, about 50% of people have some degree of hiatal hernia, increasing to 60% by age 60, and 70% by age 70. This condition is also frequently diagnosed in patients here in Sri Lanka.
What are the symptoms of a Hiatal Hernia?
If you have a sliding hiatal hernia, you might not even realize you have one. Unlike other types of hernias, there is no visible external lump.
Many people have a hiatal hernia without any symptoms. However, for those who do experience symptoms, the majority of the issues are related to Gastroesophageal Reflux Disease (GERD).
These symptoms include:
- Heartburn: A burning sensation in the chest, particularly after meals.
- Noncardiac chest pain: Recurring chest pain that feels similar to angina (coronary artery disease) but is not actually related to your heart.
- Indigestion: A feeling of fullness shortly after eating, often accompanied by abdominal discomfort.
- Burping and regurgitation: Food, air, and stomach acid coming back up into your throat.
- Difficulty swallowing or a feeling like a lump is stuck in your throat.
- Sore throat and hoarseness: Acid reaching the throat can irritate tissues and change your voice.
Keep in mind that not everyone with a hiatal hernia experiences acid reflux, and not everyone with acid reflux has a hiatal hernia. However, if you notice these symptoms occurring frequently, a hernia could be the cause.
Other warning signs may include:
- Nausea: Caused by pressure on the stomach or the presence of acid in the esophagus.
- Shortness of breath: If a large hernia presses against your lungs, it may affect your breathing.
- Pressure or pain in the upper abdomen or lower chest.
These symptoms are more commonly associated with larger paraesophageal hernias.
How does a Hiatal Hernia feel?
Because the hernia is located where your abdomen meets your chest, pain can be felt in either area. Pressure or restriction from the hernia—such as when bending forward, coughing, or lifting heavy objects—can trigger discomfort. If you experience sudden, severe pain, it could indicate a complication that requires immediate medical attention.
Most of the time, the discomfort associated with a hiatal hernia is actually caused by the resulting acid reflux, which irritates the lining of the esophagus. This can feel like burning that radiates throughout the chest. Because of the location, it can sometimes mimic the symptoms of a heart attack. If you ever have chest pain, it is always safest to consult a doctor immediately to rule out cardiac issues.
How does a hernia cause acid reflux?
Think of the junction where your esophagus meets your stomach. When that junction moves above the diaphragm, the muscle fibers that normally act as a valve to prevent acid from backing up become weakened or stretched. Because these muscles cannot close the esophagus tightly enough, stomach acid easily leaks upward. Furthermore, a hiatal hernia can trap a small amount of stomach acid in the pouch formed by the hernia, making it harder for the stomach to empty properly.
What causes a Hiatal Hernia?
Hernias occur when there is a weak spot in the tissue barrier that separates parts of your body. A hiatal hernia specifically occurs when the opening in the diaphragm (the esophageal hiatus) becomes enlarged, allowing the stomach to push through.
Sometimes this weakness can occur due to a specific injury, surgery, or even a congenital condition. However, it is most commonly the result of years of cumulative tissue damage from chronic daily pressure and strain. Anything that increases pressure within your abdominal cavity can eventually affect your diaphragm. Here are several key factors that contribute to the development of a hiatal hernia:
- Chronic coughing or sneezing: Think about those suffering from a persistent cough. Constant coughing or sneezing significantly increases intra-abdominal pressure.
- Persistent straining during bowel movements (constipation): If you suffer from chronic constipation, you know how this strain impacts the body.
- Obesity: A Body Mass Index (BMI) of 30 or higher puts significant strain on your abdominal wall.
- Frequent vomiting.
- Strenuous exercise or heavy lifting: Lifting excessively heavy weights at the gym can create intense internal pressure.
- Pregnancy and childbirth: These periods involve natural, significant increases in abdominal pressure.
Is a Hiatal Hernia a serious condition?
Usually, no. Most hiatal hernias are not dangerous. Many people don't even experience symptoms, and you might not even be aware that you have one. However, larger hernias can become serious over time and are more likely to present with noticeable symptoms.
What are the possible complications?
The most common issue caused by a hiatal hernia is chronic acid reflux. If this is severe and cannot be managed effectively with medication, it can lead to long-term damage to your esophagus.
Complications resulting from chronic acid reflux include:
- Esophagitis: Acid reflux causes the lining of the esophagus to become inflamed or ulcerated, leading to pain, difficulty swallowing, and potentially bleeding.
- Esophageal stricture: Chronic inflammation can lead to the formation of scar tissue in the esophagus. These strictures can narrow the passageway, making it difficult for food to pass.
- Barrett’s esophagus: Ongoing damage can sometimes cause changes in the esophageal tissue. While not harmful on its own, it is considered a precancerous condition that requires medical monitoring.
Very rarely, a hernia can become trapped or severely compressed within the diaphragm. This typically occurs with less common types of hernias. Such complications include:
- Gastrointestinal obstruction: Your stomach or another organ may become trapped or twisted, blocking the digestive tract.
- Gastritis: Trapped stomach acid can cause inflammation and ulcers within the herniated portion of the stomach.
- Ischemia: If the hernia is compressed tightly enough, it can cut off its own blood supply. This leads to swelling, intense pain, and eventually tissue death. This is a medical emergency; seek immediate care at an emergency room.
How is a Hiatal Hernia diagnosed?
Doctors typically identify a hiatal hernia by examining images of your esophagus and stomach. Sometimes, it is discovered incidentally during tests for other conditions. However, your physician will likely investigate further if you report symptoms of acid reflux. You may first undergo an esophageal pH test to confirm the presence of acid. If confirmed, imaging tests will be used to determine the cause.
Common diagnostic tests include:
- Chest X-ray: Provides a clear view of the chest cavity.
- Esophagram (Barium Swallow): This acts like a real-time video of your esophagus. After swallowing a barium liquid, your doctor can watch your esophagus function in real-time.
- Upper endoscopy: A thin, flexible tube with a camera is passed down your throat to allow the doctor to see the interior of your esophagus and stomach. Tissue samples (biopsy) can be taken if necessary.
- Esophageal manometry: A catheter is inserted to measure the pressure and muscle contractions within your esophagus.
Does a hernia go away on its own?
No. A hernia does not heal itself. Generally, they tend to worsen over time.However, this does not mean your hernia will cause you distress. If your hiatal hernia is asymptomatic, you may not require treatment. If you do have symptoms, they may persist or progress. Mild reflux can often be managed with medication, but severe cases may eventually require surgical repair.
What are the medical treatments for a Hiatal Hernia?
Your doctor will determine the best long-term strategy based on the nature of your hernia, the severity of your symptoms, and your overall health. Options include:
- Wait and watch: If your hernia is not causing issues, you may simply be monitored to see if it changes over time.
- Medications: While drugs cannot fix the hernia, they can reduce stomach acid, alleviating pain and preventing damage to the esophagus.
- Surgery: A minor surgical procedure can repair the hernia. Surgery is an option for many, though it is not required for everyone.
Medications
For occasional acid reflux, over-the-counter antacids can provide temporary relief. However, if symptoms are frequent, your doctor may prescribe Proton Pump Inhibitors (PPIs) (such as Omeprazole or Esomeprazole). These are highly effective at healing esophageal damage, though they do not stop the hernia from growing or prevent food from regurgitating.
Surgery
Doctors at Nirogi Lanka may recommend surgical repair if:
- Symptoms or complications cannot be controlled with medication.
- Medications cause side effects that impact your quality of life.
- The size of the hernia suggests a high risk of future, more severe complications.
During hiatal hernia surgery, the procedure typically involves:
- Moving the stomach and the lower part of the esophagus back into their correct position below the diaphragm.
- Repairing the opening in the diaphragm.
- Strengthening the junction between the esophagus and the stomach.
This procedure is called Fundoplication. The name is derived from the “fundus,” which is the upper part of your stomach. During the surgery, your surgeon takes the fundus of your stomach, wraps it around the lower part of your esophagus, and secures it with surgical staples or sutures. Think of it like wrapping a scarf around your neck. This tightens the lower esophageal sphincter, the muscle that separates these two organs. Whenever possible, this is performed as a minimally invasive laparoscopic surgery, meaning the surgeon uses a camera and instruments inserted through a few small incisions.
What is the recovery process like after surgery?
Depending on your health and the type of surgery performed, you may need to stay in the hospital for a day or two. Recovery from laparoscopic surgery or robotic surgery is typically faster and more comfortable because it involves smaller incisions rather than the large cut required for open surgery. However, in some cases, open surgery may be medically necessary.
Once you return home, you will need a recovery period of two to six weeks. During this time, you may experience temporary symptoms and side effects that make eating normally difficult while your body heals. Your doctor will prescribe a very specific diet. You will likely start with liquids, gradually move to soft foods, and eventually transition to solid meals. It is common to experience some weight loss—typically 10-15 pounds (4.5–6.8 kg)—following hiatal hernia surgery.
How successful is hiatal hernia surgery?
Hiatal hernia surgeries have a 90% success rate.Many patients are able to stop taking medication and live free from the discomfort of acid reflux after the procedure. After you recover, you should see your doctor at least once a year to ensure the repaired area is functioning correctly. If you experience new symptoms or if old ones return, your medical team will investigate accordingly.
Long-term studies indicate that in about 50% of cases, a hiatal hernia may recur over time (typically after several years). This can happen if a part of the repair did not hold or if the underlying factors that caused the original hernia are still present. Not every recurring hernia causes the same symptoms, but if they do, a follow-up surgery can often provide a permanent solution.
What can I do at home to manage a hiatal hernia?
If you are living with a hiatal hernia that only causes occasional symptoms, you can try to find relief at home through over-the-counter medications and lifestyle changes. Antacids—such as Tums®, Rolaids®, or Pepto-Bismol®—can help manage occasional acid reflux, but they should not be used as a long-term, daily solution. You can also reduce the frequency and severity of acid reflux with the following lifestyle adjustments:
- Maintain a healthy Body Mass Index (BMI): If excess weight is contributing to your acid issues, losing weight can be highly effective.
- Eat smaller, frequent meals: Instead of large meals, eat smaller portions throughout the day to reduce pressure on your stomach.
- Reduce fatty foods: Greasy or high-fat foods can increase the production of stomach acid and enzymes.
- Eat dinner earlier: Avoid lying down for several hours after eating so that gravity can work in your favor.
- Change your sleep position: Sleeping with your head elevated and lying on your left side can help prevent acid from traveling back up. Special body pillows are available to assist with this.
- Stop smoking: Smoking weakens the lower esophageal sphincter. Furthermore, it can cause a chronic cough, which puts additional pressure on the muscles surrounding a hiatal hernia.
You might discover you have a hiatal hernia incidentally while visiting a doctor for another issue. These are very common; if yours is small and causes no discomfort, it is usually nothing to worry about. Alternatively, you may have spent years dealing with worsening symptoms before finally finding the cause. You might be surprised to learn that your acid reflux is actually being caused by a hernia.
Fortunately, effective treatments exist for both acid reflux and hiatal hernias. The treatment you need depends on the nature of your hernia and the severity of your symptoms. In many cases, medication and lifestyle changes are enough to manage the problem. In more severe cases, surgery to repair the hernia may be necessary. This surgery is highly successful. Once your diagnosis is clear, you will be on the path toward finding symptom relief.
Important Final Notes
A hiatal hernia is nothing to fear. Many people have them and never show any symptoms at all.
However, if you experience persistent heartburn, food coming back up, or difficulty swallowing, please seek medical advice immediately. Identifying whether the cause is a hiatal hernia or something else is crucial to receiving the right care.
With minor lifestyle changes and occasionally medication, this condition can be managed effectively. If surgery is needed, know that it is a modern, successful, and reliable procedure. Do not let anxiety hold you back; speak with your Nirogi Lanka doctor to find the solution that best fits your needs.
