Acid reflux happens when stomach acid flows backward into your esophagus, causing that familiar burning sensation in your chest or throat. The good news: most people can significantly reduce or eliminate episodes through a combination of dietary changes, adjusted habits, and, when needed, the right medication. Here’s what actually works.
Foods and Drinks That Make It Worse
Certain foods relax the muscular valve between your stomach and esophagus or increase acid production, making reflux far more likely. The most common culprits fall into a few categories:
- Fatty and fried foods sit in your stomach longer, giving acid more opportunity to push back up into the esophagus.
- Spicy foods, citrus, tomato sauces, and vinegar intensify heartburn by irritating an already sensitive esophageal lining.
- Chocolate, caffeine, onions, peppermint, carbonated drinks, and alcohol all tend to loosen that lower esophageal valve, letting acid escape upward.
You don’t necessarily need to cut all of these permanently. Start by removing the biggest offenders for two to three weeks, then reintroduce them one at a time. Most people find they have a handful of personal triggers rather than reacting to everything on the list. Keeping a simple food diary for a couple of weeks makes patterns obvious fast.
On the flip side, dietary fiber from whole grains, fruits, and vegetables can help. Fiber facilitates stomach emptying and reduces the number of times that lower valve relaxes inappropriately, which directly cuts down on reflux episodes.
Meal Timing and Portion Size
When and how much you eat matters as much as what you eat. Large meals stretch the stomach and put pressure on the valve at the top, making reflux more likely. Eating smaller, more frequent meals throughout the day keeps that pressure lower.
The timing of your last meal is especially important. Stop eating at least three hours before you lie down. There’s a straightforward physical reason: when you’re upright, gravity helps keep acid in your stomach. Lie down with a full stomach and you lose that advantage entirely. This single change often makes the biggest difference for people who struggle with nighttime symptoms.
How You Sleep Changes Everything
If reflux wakes you up at night or leaves you with a sore throat in the morning, adjusting your sleep setup can help dramatically. Two changes matter most.
First, elevate the head of your bed by 6 to 8 inches using blocks or a wedge placed under the mattress or bed frame. Propping yourself up with extra pillows doesn’t work as well because it bends your body at the waist, which can actually increase abdominal pressure. You want a gentle slope from your waist to your head.
Second, sleep on your left side. The American Gastroenterological Association recommends this position because of the way your stomach and esophagus are oriented. When you’re on your left side, gravity and anatomy work together to keep acid pooled away from the valve. Sleeping on your right side or your back does the opposite, allowing acid to sit right at the junction where it can escape.
Weight Loss Has a Large Impact
Excess weight, particularly around the midsection, pushes up on the stomach and forces acid toward the esophagus. Even moderate weight loss makes a measurable difference. In a large study tracking women over 14 years, losing enough weight to reduce BMI by about 3.5 points decreased the risk of frequent reflux symptoms by nearly 40%. You don’t need to reach an ideal weight to see improvement. Losing even 10 to 15 pounds often produces noticeable relief, especially if you carry weight around your abdomen.
Other physical habits help too. Avoid tight belts and waistbands that compress your stomach. Don’t exercise vigorously right after eating. Bending over or lying down shortly after meals increases pressure, so stay upright for a while after you eat.
Natural Remedies Worth Trying
Ginger has the strongest evidence among herbal options. Ginger extract improves stomach emptying and reduces reflux by stimulating the muscles that move food through your digestive tract more efficiently. You can use fresh ginger in cooking, steep it as tea, or take it in supplement form. A small amount before or with meals is the most common approach.
A European herbal blend sold as Iberogast (STW5) has also been studied in humans. It works by relaxing the upper part of the stomach while increasing contractions in the lower part, which helps move food downward and reduces the backup that causes reflux. It acts directly on the smooth muscle of the digestive tract, independent of nerve signaling.
One caution: while peppermint can soothe general digestive discomfort, it tends to relax the lower esophageal valve. That makes it a poor choice if reflux is your main problem, since it can actually worsen symptoms.
Over-the-Counter Medications Compared
Three types of medications are available without a prescription, and they work in fundamentally different ways.
Antacids (like Tums or Rolaids) neutralize acid that’s already in your stomach. They work within minutes but wear off quickly, making them best for occasional, mild episodes rather than ongoing reflux.
H2 blockers (like famotidine) reduce the amount of acid your stomach produces by blocking histamine receptors on acid-producing cells. They last about eight hours per dose and work well for predictable symptoms, like heartburn you get every evening.
Proton pump inhibitors, or PPIs (like omeprazole) block the acid-producing pump directly, providing the most powerful suppression. They reduce stomach acid for 15 to 21 hours per day, far longer than H2 blockers. The tradeoff is they can take up to four days to reach full effect, so they’re not useful for immediate relief. They’re designed for daily use over a defined period, not as-needed dosing.
Risks of Long-Term Acid Suppression
PPIs are effective, but using them for months or years carries risks that are worth understanding. Long-term use has been linked to a higher chance of a serious intestinal infection (C. difficile), reduced bone density, and poor absorption of certain vitamins and minerals. A 2025 study published in The BMJ also highlighted the importance of regularly reassessing whether continued PPI use is still necessary, rather than staying on them indefinitely by default.
If you’ve been taking a PPI for more than eight weeks without a clear plan, it’s reasonable to discuss tapering with your doctor. Many people find that after making dietary and lifestyle changes, they can step down to an H2 blocker or use medication only occasionally.
When Lifestyle Changes Aren’t Enough
For people whose symptoms persist despite medication and lifestyle adjustments, surgical options exist. The most established is Nissen fundoplication, where the top of the stomach is wrapped around the lower esophagus to reinforce the valve. It’s effective but invasive, and potential downsides include difficulty swallowing, bloating from trapped air, and the possibility that the repair weakens after eight to ten years.
A newer, less invasive alternative is transoral incisionless fundoplication (TIF), performed through the mouth with no external incisions. National studies show the procedure is completed successfully in up to 99% of patients, with only about 2% experiencing complications like a small tear or bleeding. After TIF, 89% of patients are able to stop taking PPIs entirely, and 91% see their hiatal hernia reduced. Symptom relief typically lasts eight to ten years, comparable to the traditional surgery. TIF is generally recommended for people whose reflux isn’t well controlled by medication alone.
Most people never need surgery. A consistent combination of eating smaller meals, avoiding personal trigger foods, finishing dinner three hours before bed, sleeping elevated on the left side, and losing excess weight resolves symptoms for the majority of reflux sufferers. Start with the changes that feel most manageable, build from there, and use medication strategically to bridge the gap while your new habits take hold.
