GERD (gastroesophageal reflux disease) is treated with a combination of lifestyle changes, over-the-counter medications, and sometimes prescription drugs or surgery. Most people start with simple adjustments to eating habits and sleeping position, then add acid-reducing medications if symptoms persist. The right approach depends on how frequent and severe your symptoms are.
Lifestyle Changes That Actually Work
Two lifestyle modifications have the strongest evidence behind them: losing weight and not lying down after eating. These are considered cornerstone recommendations for GERD management, and for good reason. Excess abdominal weight increases pressure on the stomach, pushing acid upward. Even modest weight loss can meaningfully reduce reflux episodes.
Staying upright for at least two to three hours after meals gives gravity time to keep stomach contents where they belong. This is especially important after dinner. Eating smaller, more frequent meals rather than large ones also reduces the volume of acid your stomach produces at any given time.
Other changes that help many people include avoiding known trigger foods (common culprits are spicy dishes, citrus, tomato-based sauces, chocolate, coffee, and alcohol), quitting smoking, and wearing loose-fitting clothing around the midsection. Not every trigger affects every person equally, so paying attention to your own patterns matters more than following a rigid elimination list.
How You Sleep Makes a Difference
Sleeping on your left side reduces acid reflux compared to sleeping on your right side or your back. The reason is simple anatomy: in that position, your stomach sits below your esophagus, making it harder for acid to travel upward. Research from Amsterdam UMC found that left-side sleepers had less stomach acid in their esophagus overall, and when acid did reach the esophagus, it cleared back into the stomach more quickly.
Elevating the head of your bed by six to eight inches also helps. This means raising the bed frame itself (with blocks or wedges under the legs), not just stacking pillows. Pillows alone can bend your body at the waist and actually increase abdominal pressure. A foam wedge that elevates your entire upper body is a good alternative if adjusting the bed frame isn’t practical.
Over-the-Counter Medications
If lifestyle changes aren’t enough, the next step is usually medication you can buy without a prescription. There are three main categories, and they work differently.
- Antacids neutralize stomach acid that’s already there. They work within minutes but wear off in one to two hours. They’re best for occasional, mild symptoms rather than daily reflux.
- H2 blockers reduce the amount of acid your stomach produces. They take 30 to 60 minutes to kick in but last longer than antacids, typically six to twelve hours. They’re useful for predictable symptoms, like reflux that hits at night.
- Proton pump inhibitors (PPIs) are the most powerful acid reducers available over the counter. They block acid production at the source and need to be taken daily (usually 30 minutes before breakfast) to work effectively. Most people notice significant improvement within a few days, though full effect can take up to two weeks.
Alginate-based products (sold under brand names like Gaviscon) work differently from standard antacids. When the alginate contacts stomach acid, it forms a gel “raft” that floats on top of your stomach contents, creating a physical barrier that prevents acid from splashing up into the esophagus. Studies have found that alginate-antacid combinations are more effective than antacids alone at controlling acid exposure after meals. These products can be especially helpful for postmeal symptoms.
Prescription Treatment for Persistent Symptoms
When over-the-counter options fall short, doctors typically prescribe higher-dose PPIs. The standard approach is a course of four to twelve weeks. For people with inflammation or damage to the esophageal lining, longer-term PPI use is often necessary, but guidelines recommend titrating down to the lowest dose that keeps symptoms under control.
If once-daily PPIs aren’t doing enough, your doctor may recommend twice-daily dosing. When that works, the goal is eventually stepping back down to once daily. For people coming off PPIs entirely, H2 blockers and antacids can help manage any rebound symptoms during the transition.
Long-term PPI use has raised some safety questions over the years, but gastroenterology guidelines are clear that for people with confirmed GERD and esophageal inflammation, the benefits of continued treatment generally outweigh the risks. The key is making sure you actually need them and aren’t staying on a high dose out of habit.
When Medication Isn’t Enough: Surgery
Surgery becomes an option when medications don’t control symptoms adequately, when you can’t tolerate long-term medication, or when you simply prefer a more permanent solution. Guidelines recommend trying PPI therapy first because of its strong safety profile, but surgery can offer lasting relief for the right candidates. Two procedures dominate the field.
Nissen Fundoplication
This is the traditional anti-reflux surgery, performed laparoscopically. The surgeon wraps the top of the stomach around the lower esophagus to reinforce the valve that’s supposed to keep acid down. It has an impressive track record: about 92% of patients report heartburn resolution at 10 years, and 80% still have relief after 20 years.
The trade-offs are real, though. Up to 26% of patients experience some return of symptoms like heartburn, regurgitation, or difficulty swallowing over time. New side effects can also appear, including bloating (up to about 20% of patients), difficulty swallowing (around 17%), and an inability to belch or vomit. These side effects improve for many people over the first year but persist in some.
LINX Device
A newer option involves a small ring of magnetic beads placed around the lower esophagus. The magnets are strong enough to keep the valve closed against reflux but weak enough to open when you swallow. At five-year follow-up, 75 to 85% of LINX patients have stopped taking PPIs entirely, and 84% report significantly improved quality of life.
Difficulty swallowing is the most common early complaint, affecting anywhere from 43 to 83% of patients in the weeks after surgery. This usually improves as the body adjusts, but persistent swallowing problems occur in up to 19% of patients. Roughly 30 to 43% of patients need a procedure to stretch the esophagus at some point after implantation. In a small percentage of cases (1 to 7%), the device needs to be removed entirely.
How GERD Gets Diagnosed
Most people with classic heartburn and regurgitation that responds to acid-reducing medication are diagnosed based on symptoms alone. But when symptoms are unusual, don’t respond to treatment, or when surgery is being considered, doctors use more precise testing.
The most definitive test is ambulatory pH monitoring, where a small sensor placed in your esophagus measures acid levels over 24 to 48 hours while you go about your day. The key measurement is what percentage of time your esophageal pH drops below 4.0 (meaning acid is present). If that number exceeds 4.3% of the total recording time, the result confirms abnormal acid exposure. For patients already taking acid-suppressing medication during the test, the threshold is lower: anything above 1.3% is considered abnormal.
An upper endoscopy, where a thin camera is passed down your throat, lets doctors visually check for inflammation, erosion, or narrowing of the esophagus. This is particularly important for people who’ve had symptoms for years, as chronic acid exposure can cause changes to the esophageal lining that need monitoring.
