What is a Hiatus Hernia?
A hiatus hernia occurs when part of the stomach pushes up through the diaphragm into the chest cavity. The diaphragm is the muscle wall that separates the abdomen from the chest and helps in breathing. At its base is an opening called the hiatus, through which the esophagus passes to connect to the stomach. In a normal setting, the stomach stays below the diaphragm. But in the case of a hiatus hernia, it slips upward through this opening, causing discomfort, heartburn, and sometimes more serious complications.
This condition is surprisingly common, especially among people over the age of 50. Many people with a small hiatus hernia may not even realize they have it because they might not experience any symptoms. However, larger hernias can cause severe reflux, chest pain, difficulty swallowing, and more.
There are several misconceptions about hiatus hernias. Some believe it's a life-threatening condition, while others think surgery is always necessary. The truth lies somewhere in between. While most cases can be managed conservatively, surgery becomes essential when symptoms are severe, persistent, or complications like strangulation occur. Understanding what a hiatus hernia is lays the groundwork for understanding the various treatment paths—including surgery.
Types of Hiatus Hernias
Not all hiatus hernias are the same. In fact, they’re classified into two main categories: sliding and paraesophageal.
Sliding Hiatus Hernia
Sliding hernias are the most common type. In this case, the stomach and the lower part of the esophagus slide up into the chest through the hiatus. The movement is usually intermittent, meaning the stomach may move up and down depending on posture or abdominal pressure. This type of hernia is typically associated with gastroesophageal reflux disease (GERD), which is why many patients experience heartburn, regurgitation, and discomfort after meals.
Sliding hernias are often less serious and are frequently managed with medications and lifestyle adjustments. However, if symptoms persist or worsen, surgical intervention might be recommended to strengthen the area and prevent the stomach from slipping again.
Paraesophageal Hiatus Hernia
This is a less common but more concerning form of hiatus hernia. In a paraesophageal hernia, part of the stomach pushes through the hiatus and sits next to the esophagus. Unlike sliding hernias, the esophagus and stomach do not move together. Instead, a portion of the stomach becomes trapped, increasing the risk of strangulation—a condition where the blood supply to the stomach is cut off.
Because of this risk, paraesophageal hernias often require surgical repair even if symptoms are mild. These hernias might not cause reflux, which makes them harder to detect without imaging. However, symptoms like difficulty swallowing, chest pain, or a feeling of fullness after eating can be clues.
Causes and Risk Factors
What Causes a Hiatus Hernia?
While the exact cause of a hiatus hernia is not always clear, several factors are known to contribute. One major reason is the weakening of the muscle tissue around the diaphragm due to aging. As we get older, our muscles—including the diaphragm—tend to lose elasticity and strength, making it easier for the stomach to push through.
Other common causes include:
Increased pressure in the abdominal cavity from obesity or pregnancy
Heavy lifting or straining during bowel movements
Chronic coughing or vomiting
Genetic predisposition or congenital defects
People who have experienced trauma to the chest or abdomen may also develop a hiatus hernia due to physical changes in the diaphragm or stomach.
Ultimately, it's often a combination of factors rather than a single cause. For instance, someone who is overweight and frequently lifts heavy objects may be more prone to developing this condition than someone who only has one risk factor.
Risk Factors You Should Know
Knowing what increases your risk can help with early diagnosis and prevention. Common risk factors include:
Age: People over 50 are more likely to develop a hiatus hernia.
Obesity: Excess body weight increases abdominal pressure.
Pregnancy: Hormonal changes and pressure from the growing uterus can contribute.
Smoking: It weakens the diaphragm and increases acid reflux.
Previous surgeries or injuries: These can compromise the structural integrity of the diaphragm.
While you can't control all risk factors (like aging), others such as weight management and quitting smoking are within your grasp. Awareness is key—if you're in a high-risk group, regular check-ups can help catch a hernia before it becomes severe.
Symptoms and Diagnosis
Common Symptoms of a Hiatus Hernia
Recognizing the symptoms of a hiatus hernia can be tricky because they often mimic those of other digestive disorders. In fact, many people discover they have a hernia only after undergoing tests for something else. However, if you're experiencing persistent digestive issues, a hiatus hernia might be the culprit.
The most common symptoms include:
Heartburn: A burning sensation in the chest caused by acid reflux, especially after eating or lying down.
Regurgitation: Sour or bitter-tasting acid backing up into the throat or mouth.
Difficulty swallowing (dysphagia): A feeling that food is stuck in the throat or chest.
Chest pain: Often mistaken for a heart condition, this discomfort can be dull or sharp.
Belching and bloating: Due to trapped gas and disrupted digestion.
Shortness of breath: Especially if the hernia is large and pressing against the lungs.
Some patients also report nausea, a chronic cough, or a hoarse voice. These symptoms may worsen after heavy meals, bending over, or lying flat. It’s worth noting that not everyone will experience all of these issues—some people have no symptoms at all. These are often the “silent” hernias detected incidentally during imaging for other concerns.
Persistent or worsening symptoms should never be ignored, as they may indicate complications like esophageal damage or strangulation in the case of a paraesophageal hernia.
How is a Hiatus Hernia Diagnosed?
If your doctor suspects a hiatus hernia, a series of diagnostic tests can confirm the condition and determine its severity. These tests include:
Barium Swallow X-ray: You’ll drink a chalky liquid that coats your esophagus and stomach, making them visible on X-rays. This test helps identify the size and type of hernia.
Upper Endoscopy (EGD): A thin, flexible tube with a camera is passed through the throat to view the esophagus and stomach. This test can also reveal inflammation, ulcers, or complications from reflux.
Esophageal Manometry: This measures the rhythmic muscle contractions in your esophagus and the pressure exerted by the lower esophageal sphincter (LES).
pH Monitoring: Used to detect acid in the esophagus, helping to evaluate the severity of GERD symptoms associated with the hernia.
In some cases, a combination of tests is needed to provide a full picture. These diagnostic tools not only confirm the presence of a hernia but also help determine the best course of treatment—whether lifestyle changes, medication, or surgery.
Early diagnosis is crucial because untreated hernias can lead to esophageal damage, strictures, or Barrett’s esophagus, a precancerous condition. If you’ve been experiencing ongoing reflux or digestive discomfort, it’s definitely time to talk to a doctor.
Treatment Options
Lifestyle and Dietary Changes
Before jumping into medications or surgery, doctors often recommend making some simple but powerful changes to your daily habits. These lifestyle tweaks can significantly reduce symptoms and even prevent the hernia from worsening.
Here are the most effective changes:
Eat smaller, more frequent meals: Large meals can increase pressure in your abdomen and worsen reflux.
Avoid trigger foods: Spicy dishes, chocolate, citrus, caffeine, alcohol, and fatty foods can all irritate the stomach and esophagus.
Don't lie down right after eating: Wait at least 2-3 hours before reclining to prevent stomach acid from creeping up.
Elevate your head while sleeping: Using a wedge pillow or raising the head of your bed can reduce nighttime reflux.
Lose weight: Shedding even a few pounds can relieve pressure on your diaphragm.
Quit smoking: Tobacco weakens the LES, increasing acid reflux.
Wear loose-fitting clothes: Tight waistbands or belts can squeeze your abdomen and make symptoms worse.
These changes might sound simple, but they can have a big impact. Many patients see a noticeable improvement in their symptoms with just these steps. It’s all about reducing pressure in the stomach and supporting healthy digestion.
Medications for Hiatus Hernia
When lifestyle changes aren’t enough, medications come into play. These don’t “fix” the hernia, but they help manage the symptoms—especially acid reflux and inflammation.
Here are the main types of medications used:
Antacids: Provide quick relief by neutralizing stomach acid (e.g., Tums, Rolaids).
H2-receptor blockers: Reduce acid production and offer longer-lasting relief (e.g., ranitidine, famotidine).
Proton pump inhibitors (PPIs): More powerful than H2 blockers, they block acid production at the source (e.g., omeprazole, lansoprazole).
Prokinetics: Help strengthen the LES and move food through the stomach faster (e.g., metoclopramide).
These drugs are usually well-tolerated but not without risks. Long-term PPI use, for example, has been linked to nutrient deficiencies and gut infections. That’s why it’s crucial to use them under medical supervision.
Medications work best when combined with dietary and lifestyle changes. If you find yourself relying on pills daily or still struggling with symptoms, it may be time to consider surgery as a more permanent solution.
When is Surgery Needed?
Surgery for a hiatus hernia isn’t always necessary. But there are times when it’s not just recommended—it’s essential.
Here are signs you might need surgery:
Severe or persistent symptoms that don’t respond to medications
Large paraesophageal hernias that risk strangulation
Chronic GERD complications, such as Barrett’s esophagus or esophagitis
Difficulty swallowing or feeling of obstruction
Bleeding ulcers or severe anemia related to the hernia
The goal of surgery is to restore the stomach to its proper position, tighten the opening in the diaphragm, and, in many cases, reinforce the LES to prevent acid reflux. The decision to operate is never taken lightly and is made after weighing the severity of symptoms, overall health, and the risks involved.
Modern surgical techniques have made the procedure safer and recovery quicker than ever before.
Hiatus Hernia Repair Surgery Explained
Types of Surgical Procedures
When it comes to fixing a hiatus hernia surgically, there are a couple of different approaches. The choice depends on the size of the hernia, the severity of symptoms, and the overall health of the patient. Let’s break down the most commonly used surgical procedures.
Laparoscopic Nissen Fundoplication
This is the most common and preferred surgical method for repairing a hiatus hernia. It’s minimally invasive, which means it involves smaller incisions, less pain, and quicker recovery.
Here’s how it works:
The surgeon makes 4 to 5 small incisions in the abdomen.
A laparoscope (a thin tube with a camera) is inserted to provide a detailed view of the stomach and diaphragm.
The herniated stomach is gently pulled back into the abdomen.
The opening in the diaphragm (the hiatus) is tightened to prevent recurrence.
The top portion of the stomach (the fundus) is wrapped around the lower end of the esophagus. This “wrap” reinforces the lower esophageal sphincter, reducing acid reflux.
The whole procedure usually takes 1 to 2 hours, and patients are often discharged within a day or two. The success rate is high, and most people experience long-term relief from their symptoms.
Open Surgery
In rare or more complex cases, open surgery might be necessary—especially if there’s a large hernia, previous surgeries in the area, or complications. This involves a larger incision in the abdomen or chest, allowing the surgeon direct access to the hernia.
While open surgery has a longer recovery period and more potential for pain, it can be more effective for complicated cases where laparoscopic surgery isn’t feasible. Both techniques aim for the same outcome—returning the stomach to its rightful place and preventing future herniation.
How to Prepare for Surgery
Preparing for hiatus hernia surgery is just as important as the operation itself. Good preparation helps reduce risks, ensures a smoother recovery, and sets you up for long-term success.
Here’s what to expect:
Medical Evaluation: Your doctor will perform blood tests, imaging (like endoscopy or a CT scan), and possibly heart or lung function tests to ensure you’re fit for surgery.
Medication Review: Certain medications—like blood thinners, NSAIDs, or diabetes medications—may need to be stopped or adjusted before surgery.
Fasting: You’ll be asked to stop eating and drinking at least 8 hours before the procedure to prevent complications during anesthesia.
Quit Smoking: Smoking can interfere with healing, so you’ll be advised to stop at least a few weeks prior.
Arrange Support:Although you will not need to rest post-surgery, arrange for a family member or friend to help with meals, transportation, or childcare for a few days.
Mentally preparing is important too. Talk to your surgeon about what to expect, possible complications, and how long recovery might take. Knowing what’s ahead can ease anxiety and help you feel more in control of the process.
The Surgical Procedure
Step-by-Step Surgical Process
Whether you’re undergoing laparoscopic or open surgery, the steps are relatively similar in terms of what’s being corrected. Here’s a simplified step-by-step breakdown of the process:
Anesthesia: You’ll be given general anesthesia to ensure you’re asleep and pain-free throughout the operation.
Access: For laparoscopic surgery, small incisions are made and the abdomen is inflated with gas to give the surgeon a better view. For open surgery, a larger single incision is used.
Reducing the Hernia: The surgeon gently pulls the herniated part of the stomach back into the abdominal cavity.
Repairing the Hiatus: The opening in the diaphragm (hiatus) is tightened with sutures to close the gap and prevent future herniation.
Fundoplication: In most cases, the surgeon wraps the upper part of the stomach around the lower esophagus (usually a 360-degree wrap in a Nissen fundoplication). This helps prevent acid from backing up.
Closure: The instruments are removed, gas is released from the abdomen, and the incisions are closed with sutures or surgical glue.
The entire procedure usually lasts 1 to 2 hours. Most patients wake up in a recovery room and are monitored for any immediate post-op concerns like nausea, bleeding, or breathing issues.
Anesthesia and Hospital Stay Duration
General anesthesia is used in all hiatus hernia repair surgeries. It ensures you’re completely unconscious and pain-free throughout the procedure. While most patients tolerate anesthesia well, your medical team will monitor your heart rate, breathing, and blood pressure the entire time.
Hospital stays vary depending on the type of surgery and individual recovery speed. With laparoscopic surgery, many patients go home within 24 to 48 hours. Open surgery patients may need 3 to 5 days in the hospital. The goal is to ensure you can eat, move, and manage pain before discharge.
After leaving the hospital, you’ll need a few weeks of rest before resuming regular activities. Recovery can be smooth, especially with the right post-surgery care and follow-up.

Recovery After Hiatus Hernia Surgery
Post-Surgery Care Tips
The recovery phase is just as important as the surgery itself. Following your surgeon’s instructions carefully will not only speed up healing but also help avoid complications. Here’s what to expect—and what you should do—after your hiatus hernia repair surgery.
Pain Management: Mild to moderate pain at the incision site is common. You’ll likely receive prescription or over-the-counter pain relievers to manage discomfort. Avoid taking NSAIDs unless specifically allowed, as they can irritate the stomach.
Wound Care: Keep the surgical area clean and dry. Follow your surgeon's instructions on changing dressings or monitoring for signs of infection (like redness, swelling, or discharge).
Avoid Heavy Lifting: For about 3 months, you should avoid lifting anything heavier than 3-5 Kgs to prevent straining the surgical site.
Walk Frequently: Light walking is encouraged as soon as possible to promote circulation, reduce the risk of blood clots, and improve digestion.
Follow-Up Appointments: Don’t skip them. Your surgeon will check healing progress and ensure the hernia repair is holding up well.
Medications: Continue acid-reducing medications for a short while if prescribed. Some patients taper off these as the LES becomes stronger after the wrap.
Recovery timelines vary from person to person, but most can resume normal daily activities within 2 to 4 weeks. Full recovery might take up to 6 weeks or more, especially for open surgery patients.
Patience is key. Rushing back to your usual routine or ignoring your body’s signals can increase the risk of recurrence or complications.
Diet After Surgery
Your digestive system needs a little TLC after surgery. Since the stomach and esophagus are adjusted during the procedure, easing back into eating is essential. Your doctor or dietitian will give you specific dietary guidelines, but here’s a general idea of what to expect.
Stage 1: Clear Liquids (Day 1-2)
Broth
Clear juices (apple, cranberry)
Water and electrolyte drinks
Gelatin
Stage 2: Full Liquids (Day 3-5)
Smooth soups
Milk and milk alternatives
Pudding and custards
Protein shakes
Stage 3: Soft Foods (Week 1-2)
Mashed potatoes
Scrambled eggs
Cooked vegetables
Soft fish or ground meats
Stage 4: Normal Foods (Week 3 onward)
Introduce regular foods slowly
Chew thoroughly
Avoid carbonated drinks, hard/crunchy items, and large bites
Avoid eating too quickly, drinking through straws (which can increase gas), and lying down right after meals. Small, frequent meals are best—5 to 6 times a day. These habits help your newly tightened stomach adjust without causing bloating, discomfort, or regurgitation.
Physical Activity and Restrictions
While rest is essential in the first few days, prolonged inactivity can actually slow your recovery. Start with light walking around your home a few times a day. It’s good for your lungs, prevents blood clots, and promotes bowel movements.
Things to Avoid for 4–6 Weeks:
Heavy lifting
Intense workouts or abdominal exercises
Bending or twisting motions
Driving if you’re on pain medications
Gradually reintroduce your normal exercise routine after your surgeon gives the green light. Most people return to light activity after 2 weeks and more strenuous workouts increasing gradually after 6–8 weeks, depending on their overall condition.
Be kind to your body—healing takes time, and rushing it could lead to setbacks.
Risks and Complications
Common Side Effects
Like any surgical procedure, hiatus hernia repair surgery carries some risks. The good news? Most complications are rare and treatable when caught early.
Common (but usually temporary) side effects include:
Sore throat from the breathing tube used during anesthesia
Mild nausea and bloating post-surgery
Shoulder pain due to gas used during laparoscopy
Trouble swallowing (dysphagia), especially in the first few weeks
Fatigue during the healing process
Swallowing issues usually resolve on their own within a few weeks, but persistent symptoms may require an endoscopic dilation to stretch the esophagus slightly. This is rarely needed but helpful if the esophagus becomes too tight from the surgical wrap.
Long-Term Complications to Watch Out For
Though uncommon, there are potential long-term issues that can arise. It’s important to be aware so you can address them promptly.
Recurrence of the hernia if the diaphragm opening stretches again. This is more likely if you return to heavy lifting or strain too soon after surgery.
Wrap migration or failure where the stomach wrap loosens or shifts.
Chronic dysphagia if the esophagus remains too narrow long-term.
Bloating and gas issues due to inability to burp properly (sometimes called gas-bloat syndrome).
Dumping syndrome, a rare condition where food moves too quickly into the small intestine, causing nausea, dizziness, and diarrhea.
Maintaining a healthy lifestyle post-surgery-managing your weight, eating well, and avoiding bad habits like smoking-can help minimize the risk of these complications.
Regular follow-ups with your surgeon ensure any issues are caught early and managed effectively.
