Acid reflux happens when stomach acid flows back up into your esophagus, causing that familiar burning sensation in your chest or throat. The good news: most people can reduce or eliminate symptoms through a combination of dietary changes, sleep adjustments, and over-the-counter options. Here’s what actually works.
Change What and How You Eat
Certain foods relax the muscular valve between your stomach and esophagus, letting acid escape upward. Others slow digestion, keeping food in your stomach longer and increasing the chance of reflux. The most common triggers are foods high in fat, salt, or spice: fried food, fast food, pizza, fatty meats like bacon and sausage, cheese, and processed snacks like potato chips. Tomato-based sauces, citrus fruits, chocolate, peppermint, and carbonated beverages also cause problems for many people. Even milk, often thought of as soothing, can aggravate reflux because of its fat content.
You don’t necessarily need to cut all of these permanently. Start by eliminating the most common offenders for two to three weeks, then reintroduce them one at a time to identify your personal triggers. Some people can handle tomato sauce but not chocolate, or vice versa.
How you eat matters as much as what you eat. Smaller, more frequent meals put less pressure on that valve than large ones. Stop eating at least two to three hours before lying down, so your stomach has time to empty. Eating slowly and chewing thoroughly also helps, since gulping food forces you to swallow more air and leaves larger pieces for your stomach to process.
Adjust Your Sleep Position
Nighttime reflux is often the most disruptive, and gravity is a big part of why. When you lie flat, acid can easily pool at the base of your esophagus. Raising the head of your bed by six to eight inches, using a wedge pillow or blocks under the bed frame, creates enough of an incline to keep acid down while still allowing comfortable sleep. Stacking regular pillows doesn’t work as well because it bends your body at the waist rather than elevating your entire torso.
Side matters too. Sleeping on your left side positions your stomach below your esophagus, making it harder for acid to travel upward through a weakened valve. Right-side sleeping does the opposite, essentially tilting the opening downward and inviting reflux. If you tend to roll over at night, a body pillow behind your back can help you stay in position.
Lose Weight if You Need To
Excess weight, especially around the midsection, puts constant pressure on your stomach and pushes acid upward. This is one of the most effective long-term fixes for chronic reflux, though it takes time. A large study found that women who reduced their BMI by about 3.5 points over time cut their risk of frequent reflux symptoms by nearly 40%. Other research shows that a weight loss of 5 to 10% in women, or more than 10% in men, leads to meaningful drops in overall symptom scores. In one documented case, a patient who brought their BMI from 25.5 down to 19.8 over three years improved so much that they were able to stop taking acid-suppressing medication entirely.
You don’t need to reach a specific target weight. Even modest reductions in belly fat can relieve the mechanical pressure driving your symptoms.
Over-the-Counter Medications
Three main categories of acid reflux medication 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 and are best for occasional, mild heartburn. Relief is real but short-lived, typically lasting an hour or two.
- H2 blockers (like famotidine, sold as Pepcid) reduce the amount of acid your stomach produces by blocking one of the chemical signals that triggers production. They provide about eight hours of relief and work well for predictable symptoms, like heartburn you get after dinner every night.
- Proton pump inhibitors, or PPIs (like omeprazole, sold as Prilosec) block the acid-producing pumps in your stomach lining more completely. They suppress acid for 15 to 21 hours a day, making them the strongest option. The tradeoff: they can take up to four days to reach full effect, so they’re not useful for quick relief. They’re designed for daily use over a set period, typically two weeks for over-the-counter versions.
For a sudden flare, start with an antacid. If you’re dealing with reflux several times a week, an H2 blocker or PPI makes more sense because it prevents acid production rather than just neutralizing what’s already there.
Alginate-Based Products
Alginate products (like Gaviscon Advance) work differently from all three categories above. When the alginate mixes with your stomach acid, it forms a gel-like raft that floats on top of your stomach contents. This physical barrier sits between the acid and your esophagus, blocking it from flowing upward. Unlike antacids, alginates don’t change your stomach’s acidity. They simply create a floating lid. This makes them particularly useful right after meals, when reflux is most likely, and they’re generally safe for frequent use.
Baking Soda as a Quick Fix
Dissolving half a teaspoon of baking soda in a glass of water creates a basic solution that neutralizes stomach acid on contact. It works fast and can provide temporary relief when you don’t have antacids on hand. But it’s not a regular solution. Baking soda contains a large amount of sodium, so anyone with high blood pressure, heart disease, kidney disease, or edema should avoid it. It’s also not appropriate for children under six. Keep it as an occasional emergency measure, not a daily habit.
Other Habits That Help
Tight clothing, especially anything that squeezes your waistline, increases abdominal pressure and can push acid upward. Switching to looser pants or skipping the belt during meals makes a noticeable difference for some people. Smoking weakens the valve between your stomach and esophagus, so quitting has a direct effect on reflux frequency. Alcohol relaxes that same valve and stimulates acid production, a double hit.
Stress doesn’t cause acid reflux directly, but it can heighten your sensitivity to the sensation and lead to behaviors (eating quickly, drinking more alcohol, eating later at night) that make symptoms worse. Regular physical activity helps both with weight management and stress reduction, though intense exercise right after eating can temporarily worsen reflux. Walking after meals is fine and may actually speed stomach emptying.
Risks of Long-Term Acid Suppression
If you find yourself taking PPIs for months or years, it’s worth understanding the tradeoffs. Long-term use has been linked to increased fracture risk (because suppressing acid interferes with calcium absorption), higher rates of certain infections including pneumonia, and deficiencies in magnesium, iron, and vitamin B12. All of these stem from the same basic mechanism: your body needs stomach acid to absorb certain nutrients and kill certain bacteria, and chronically suppressing it has downstream effects.
Earlier studies also raised concerns about dementia, kidney disease, and cardiovascular problems, but more recent analysis suggests those associations were likely coincidental rather than caused by the medications. Still, the American Gastroenterological Association issued guidelines in 2022 specifically encouraging doctors to “de-prescribe” PPIs when they’re no longer clearly needed. If you’ve been on one for a long time, it’s reasonable to discuss whether you still need it or whether lifestyle changes could replace it.
Signs That Need Medical Attention
Most reflux is uncomfortable but manageable. A few symptoms signal something more serious. Difficulty swallowing, especially if it’s getting progressively worse, can indicate narrowing of the esophagus from chronic acid damage. Unintentional weight loss alongside reflux symptoms warrants investigation. Vomiting blood or passing black stools suggests bleeding in the digestive tract. And if food feels completely stuck in your throat or chest and won’t go down, that’s an emergency room situation. Reflux that persists despite two weeks of PPI use, or that comes back as soon as you stop medication, also deserves a closer look from a gastroenterologist.
