Most hiatal hernias are treated with a combination of lifestyle changes and medications that control acid reflux. Surgery is reserved for severe cases or specific hernia types that carry a risk of complications. The right approach depends on what kind of hernia you have, how much it affects your daily life, and whether conservative measures bring enough relief.
Why the Type of Hernia Matters
There are two main types of hiatal hernia, and they call for different levels of concern. A sliding hiatal hernia, which accounts for the vast majority of cases, happens when the stomach and the lower portion of the esophagus slide upward through the opening in the diaphragm. This type is a risk factor for chronic acid reflux (GERD), and treatment focuses on managing that reflux.
A paraesophageal hernia is less common but more serious. Part of the stomach pushes up beside the esophagus and can become trapped, cutting off its own blood supply. Symptomatic paraesophageal hernias carry a higher risk of progressing to obstruction or loss of blood flow to the stomach, which can require emergency surgery. If you have this type and experience sudden severe chest pain or difficulty swallowing, that’s a medical emergency.
Lifestyle Changes That Reduce Symptoms
For most people with a sliding hiatal hernia, day-to-day habits have a significant effect on how often symptoms flare. These changes won’t fix the hernia itself, but they can dramatically reduce heartburn, regurgitation, and chest discomfort.
Eat smaller, more frequent meals. Large meals increase pressure on the stomach and push acid upward through the weakened opening in the diaphragm. Spreading your food across four or five smaller meals is more effective than eating two or three big ones.
Stay upright after eating. Wait two to three hours before lying down after a meal. Late-night snacks are particularly problematic because you’re likely heading to bed soon after.
Raise the head of your bed. If nighttime heartburn is an issue, elevate the head of your bed frame six to eight inches using blocks or a foam wedge under the mattress. Simply stacking extra pillows does not work because your body bends at the waist rather than staying on an incline, which still allows acid to travel upward.
Avoid known trigger foods. Chocolate, mint, alcohol, pepper, spicy foods, high-fat foods, and caffeinated drinks (coffee, tea, colas, energy drinks) all tend to relax the valve between the stomach and esophagus or increase acid production.
How Weight Loss Helps
Excess body weight increases pressure inside the abdomen, which pushes the stomach upward through the diaphragm and worsens reflux. Losing weight can meaningfully improve symptoms and, in some cases, reduce the size of the hernia itself. In patients with obesity who underwent hernia repair combined with a weight-loss procedure, those who achieved significant reductions in BMI consistently reported complete resolution of reflux symptoms and lower rates of hernia recurrence at follow-up. You don’t need to reach a perfect weight for this to matter. Even moderate weight loss reduces intra-abdominal pressure enough to make a noticeable difference in how often symptoms show up.
Medications for Acid Control
When lifestyle changes alone aren’t enough, medications that reduce stomach acid are the standard next step. Two main classes are used, and they work differently.
H2 blockers (such as famotidine, sold as Pepcid) suppress acid production in the stomach and work relatively quickly. They’re available over the counter and by prescription. For short-term symptom management, they’re typically taken once at bedtime or twice daily. H2 blockers are a reasonable choice for occasional flare-ups, but they’re not ideal for long-term, chronic reflux.
Proton pump inhibitors (PPIs) are stronger acid blockers and better suited for ongoing GERD. They take one to four days to reach full effect, but their suppression of acid lasts much longer than H2 blockers. If your reflux is chronic, which is common with a hiatal hernia, PPIs are generally the preferred medication. They’re available both over the counter and by prescription at higher doses.
Many people start with an H2 blocker and switch to a PPI if relief is insufficient. Your provider may also recommend an antacid for quick, temporary relief while waiting for a PPI to take effect.
When Surgery Becomes Necessary
Surgery is recommended when conservative treatment fails or when the hernia poses a direct physical risk. Specific situations that typically lead to surgical repair include severe heartburn that doesn’t respond to medication, significant inflammation of the esophagus from chronic acid exposure, narrowing of the esophagus (called a stricture), and repeated aspiration of stomach contents into the lungs causing chronic pneumonia. Symptomatic paraesophageal hernias are also frequently repaired surgically because of their risk of strangulation.
What Hernia Repair Surgery Looks Like
The most common procedure is called a Nissen fundoplication, and it’s almost always done laparoscopically (through small incisions rather than one large opening). Your surgeon makes several small cuts in the abdomen and inserts narrow tubes through which surgical instruments and a small camera are passed. The procedure involves two key steps: the surgeon wraps and stitches the top of your stomach around the lower esophagus, recreating the valve effect that prevents acid from flowing upward, and then stitches the diaphragm to narrow the opening that the esophagus passes through.
Because it’s done laparoscopically, recovery is faster than open surgery. Most people spend one to three days in the hospital and return to normal activities within a few weeks. You’ll likely be on a liquid or soft diet for the first couple of weeks as the surgical site heals.
Recurrence After Surgery
One important reality about hiatal hernia repair is that recurrence rates are higher than many people expect. In a large study of 862 patients who underwent laparoscopic repair for paraesophageal hernias, the anatomical recurrence rate was 27.3% over a median follow-up of about two and a half years. Some studies using long-term imaging have reported even higher rates, ranging from 42 to 66%, though not all recurrences cause symptoms.
Of the patients whose hernias did come back in that study, about 45% experienced symptoms, and roughly 29% of those symptomatic patients went on to have a second operation. This means that while surgery resolves symptoms for the majority of people, a meaningful percentage will need ongoing management or repeat repair. It’s worth having a realistic conversation about these numbers before deciding on surgery, especially if your symptoms are well-controlled with medication.
Choosing the Right Approach
Treatment for a hiatal hernia is not one-size-fits-all. If your hernia is small, causes only occasional heartburn, and responds to dietary changes and a PPI, there’s no reason to consider surgery. Many people live comfortably with a hiatal hernia for decades using these strategies alone. Surgery makes the most sense when reflux is severe, medications stop working, or the hernia type carries a risk of a dangerous complication like strangulation. For people with significant excess weight, addressing that through sustained weight loss can be one of the most impactful treatments available, sometimes resolving symptoms entirely without any procedure at all.
