You can decrease acid reflux by changing when, what, and how you eat, adjusting your sleep position, losing weight if needed, and using over-the-counter medications strategically. Most people see meaningful improvement by combining a few lifestyle changes rather than relying on any single fix.
Why Reflux Happens
At the bottom of your esophagus sits a ring of muscle that opens to let food into your stomach and closes to keep acid from rising back up. Reflux occurs when this muscle relaxes at the wrong time. The main trigger is stomach distension: when your stomach stretches after a meal, nerve signals travel from the stomach wall to the brainstem and back, telling that muscle to relax briefly. The larger the meal, the more frequently this happens.
Excess body weight increases the frequency of these inappropriate relaxations, and it also raises pressure inside the abdomen, pushing stomach contents upward. This is one reason reflux tends to worsen with weight gain and improve with weight loss.
Eat Smaller, Lower-Fat Meals
Since stomach distension is the primary trigger, portion size matters more than most people realize. Splitting a large dinner into two smaller meals can reduce the number of reflux episodes without changing what you eat at all.
Fat deserves special attention. High-fat and fried foods slow stomach emptying, meaning your stomach stays full and stretched for longer after eating. Choosing lower-fat versions of foods you already enjoy is one of the simplest dietary shifts you can make. This doesn’t mean eliminating fat entirely. It means avoiding the meals that leave you feeling uncomfortably full for hours: deep-fried foods, cream-based sauces, fatty cuts of meat, and rich desserts.
Other common dietary triggers include coffee, alcohol, chocolate, tomato-based foods, citrus, and carbonated drinks. These affect people differently, so rather than eliminating everything at once, pay attention to which specific foods consistently precede your symptoms.
Stop Eating Three Hours Before Bed
Nighttime reflux is particularly damaging because you swallow less during sleep, so acid stays in contact with the esophagus longer. The fix is straightforward: stop eating at least three hours before you lie down. This gives your stomach enough time to empty most of its contents before gravity is no longer helping keep acid where it belongs.
If you tend to snack late, shifting dinner earlier or having your evening snack right after dinner rather than right before bed can make a noticeable difference within days.
Elevate the Head of Your Bed
Propping up an extra pillow doesn’t work well because it bends your body at the waist, which can actually increase abdominal pressure. Instead, raise the entire head of the bed by placing 6- to 8-inch risers under the legs at the headboard end. This creates a gentle downhill slope from your esophagus to your stomach, letting gravity help keep acid down all night.
Foam wedge pillows designed for this purpose are another option, though bed risers tend to be more comfortable for long-term use since they don’t shift during the night.
Sleep on Your Left Side
A study published through Harvard Health tracked 57 people with chronic heartburn during sleep and found something interesting: sleeping position didn’t change how often acid entered the esophagus, but it dramatically changed how quickly the acid cleared. When participants slept on their left side, acid cleared much faster than when they slept on their right side or their back.
The anatomy explains this. When you lie on your left side, your stomach hangs below the junction with the esophagus, so acid pools away from the opening. On your right side, that junction is essentially submerged. If nighttime symptoms are your main problem, combining left-side sleeping with head-of-bed elevation is one of the most effective non-medication strategies available.
Lose Weight If You Carry Extra
Weight loss is one of the most well-supported interventions for reflux, and you don’t need to reach an ideal BMI to see results. A large population-based study found that a BMI reduction of about 3.5 points over time decreased the risk of frequent reflux symptoms by nearly 40%. Another hospital-based study found that women who lost 5 to 10 percent of their body weight, and men who lost more than 10 percent, experienced significant reductions in overall symptom scores.
For someone weighing 200 pounds, that means losing 10 to 20 pounds could produce a real, measurable change in how often you experience heartburn. The improvement likely comes from reduced abdominal pressure and fewer inappropriate relaxations of the lower esophageal muscle.
Chew Sugar-Free Gum After Meals
Chewing gum stimulates saliva production, and saliva naturally contains bicarbonate, a mild base that helps neutralize acid. Chewing also encourages more frequent swallowing, which pushes any acid that has crept into the esophagus back down into the stomach. Bicarbonate-containing gum amplifies this effect further.
This isn’t a substitute for other changes, but 20 to 30 minutes of gum chewing after a meal is an easy, low-cost addition that can reduce post-meal symptoms.
Over-the-Counter Medication Options
Three categories of medication are available without a prescription, and they work differently enough that choosing the right one depends on your pattern of symptoms.
- Antacids (like Tums or Maalox) neutralize acid that’s already in your stomach. They work within minutes but wear off quickly, making them best for occasional, predictable symptoms.
- H2 blockers (like famotidine) reduce the amount of acid your stomach produces by blocking one of the chemical signals that triggers acid secretion. They have a quick onset and can be taken as needed, making them useful for people who get reflux a few times a week.
- Proton pump inhibitors (like omeprazole) are the most powerful acid suppressors. They shut down the acid-producing pumps in your stomach lining. However, they need to be taken daily for 4 to 8 weeks to fully work. Taking them only when symptoms flare won’t reliably control acid levels. If once-daily dosing isn’t enough, twice-daily dosing is the next step before considering other options.
For people with confirmed esophageal damage from reflux, the American Gastroenterological Association recommends long-term PPI use at the lowest effective dose. If you’ve been on a PPI for weeks and your symptoms are well-controlled, your doctor may help you step down to a lower dose rather than stopping abruptly.
Alginate-Based Products
Alginate products (sold under brand names like Gaviscon Advance) work through a different mechanism than traditional antacids. When the alginate reaches stomach acid, it rapidly forms a gel that floats on top of your stomach contents like a raft. This physical barrier sits right at the junction between the stomach and esophagus, blocking acid from rising up. Because the formulas also contain bicarbonate, carbon dioxide bubbles form within the gel, helping it float.
Clinical performance of alginate products often exceeds what their acid-neutralizing ingredients alone would predict. The floating raft can persist for longer than a standard antacid dose lasts, making these products particularly useful for post-meal reflux. They’re worth trying if antacids alone aren’t giving you enough relief but you don’t want to commit to a daily medication.
Putting It Together
The most effective approach combines several changes at once. A practical starting point: eat smaller and lower-fat meals, stop eating three hours before bed, elevate the head of your bed, and sleep on your left side. If you’re overweight, even modest weight loss will compound the benefits of everything else. Use antacids or alginate products for breakthrough symptoms, and talk to a healthcare provider about H2 blockers or PPIs if lifestyle changes alone aren’t enough.
Most people notice improvement within one to two weeks of consistent changes. Nighttime symptoms tend to respond fastest to positional adjustments, while daytime symptoms improve more gradually as eating habits shift and weight comes down.
