Most hiatal hernias are managed without surgery, using a combination of eating habits, sleep adjustments, weight management, and sometimes medication. A hiatal hernia occurs when part of your stomach pushes up through the opening in your diaphragm, which can allow stomach acid to flow back into your esophagus. The good news: the majority of people with a hiatal hernia can control their symptoms with straightforward lifestyle changes.
Adjust How and When You Eat
Dietary changes are the first line of defense. Eating several small meals throughout the day instead of two or three large ones reduces the pressure your stomach puts on the diaphragm opening. After eating, wait at least two to three hours before lying down. Late-night snacks are particularly problematic because they combine a full stomach with a horizontal position, which is exactly when acid reflux gets worse.
Certain foods are well-known triggers that relax the valve between your stomach and esophagus or increase acid production. The common ones to limit or avoid include:
- Chocolate and mint
- Spicy foods and black pepper
- High-fat or fried foods
- Alcohol
- Caffeinated drinks (coffee, tea, colas, energy drinks)
You don’t necessarily need to eliminate all of these permanently. Many people find that tracking their symptoms for a few weeks helps them identify which specific foods cause the most trouble. Some people can tolerate coffee but not spicy food, or vice versa.
Change How You Sleep
Gravity is your ally when managing a hiatal hernia, and losing that advantage at night is why many people feel worst in the morning. Elevating the head of your bed by 6 to 8 inches helps keep stomach acid from traveling up into your esophagus while you sleep. This means raising the actual bed frame or using a foam wedge under your mattress, not just stacking pillows. Extra pillows tend to bend you at the waist, which can actually increase abdominal pressure.
Sleeping on your left side also helps. This position keeps your stomach below the esophageal opening and may improve digestion. If you’re a back or right-side sleeper, it can take a week or two to adjust, but the difference in overnight reflux is often noticeable.
Lose Weight If You Carry It Around Your Middle
Excess weight around the abdomen pushes your stomach upward and increases the pressure that forces acid into your esophagus. Central obesity, the kind that accumulates around the midsection, is especially likely to worsen hiatal hernia symptoms. Even modest weight loss can produce significant symptom relief. You don’t need to reach an ideal BMI to see improvement; reducing waist circumference by even a few inches often makes a measurable difference in how frequently you experience heartburn and discomfort.
Exercise Carefully
Staying active helps with weight management and overall digestive health, but certain exercises increase abdominal pressure and can aggravate a hiatal hernia. Activities that are generally safe include swimming, walking, light jogging, gentle yoga, and cycling.
What to avoid: heavy weightlifting or anything that causes you to strain, high-impact sports, core exercises like planks and crunches, and yoga poses that overstretch the abdominal wall (like upward dog). If you do exercise, pay attention to your breathing. Exhale during exertion and inhale as you relax. Holding your breath while lifting or pushing increases intra-abdominal pressure significantly. Compression shorts or supportive undergarments can also help reduce strain on the abdomen during activity.
Over-the-Counter and Prescription Medications
When lifestyle changes alone aren’t enough, medications that reduce stomach acid can make a real difference. There are two main categories, and both are available over the counter.
Antacids (like Tums or Rolaids) neutralize acid that’s already in your stomach. They work quickly but wear off within an hour or two, making them useful for occasional flare-ups rather than daily management.
H2 blockers reduce how much acid your stomach produces in the first place. Famotidine (sold as Pepcid) is the most commonly used and is available without a prescription. These take longer to kick in but last several hours.
Proton pump inhibitors, or PPIs, are the strongest acid-reducing option. They block acid production more completely than H2 blockers and are typically used when symptoms are frequent or more severe. Some PPIs are available over the counter, while stronger doses require a prescription. PPIs work best when taken consistently rather than as needed, and they’re generally intended for defined treatment periods rather than indefinite use.
When Surgery Becomes Necessary
Most people never need surgery for a hiatal hernia. It’s typically recommended when you have severe heartburn that doesn’t respond to medication, significant inflammation or damage to the esophagus from chronic acid exposure, narrowing of the esophagus (called a stricture), or repeated episodes of stomach acid entering the lungs and causing respiratory problems.
The most common surgical procedure is called a Nissen fundoplication. A surgeon wraps the top portion of your stomach around the lower esophagus, which reinforces the valve that keeps acid from flowing backward. This is most often done laparoscopically, meaning the surgeon works through four to six small incisions using a camera and miniature instruments rather than one large opening. The procedure typically takes one to three hours. Recovery from the laparoscopic approach is considerably faster than open surgery, with most people returning to normal activities within a few weeks.
After surgery, you’ll likely need to eat soft foods for a period and adjust to smaller meals while the surgical site heals. Some people experience temporary difficulty swallowing or increased gas, but these side effects usually resolve within a few months.
Symptoms That Need Immediate Attention
While most hiatal hernias are a nuisance rather than a danger, a rare complication called strangulation can occur. This happens when the portion of stomach that has pushed through the diaphragm gets its blood supply cut off. Warning signs include sudden, severe abdominal pain that keeps getting worse, nausea and vomiting, and skin color changes around the abdomen (the area may turn red or darker than usual, then pale). This is a medical emergency requiring immediate treatment. If you experience these symptoms together, go to the emergency room or call 911.
