You can reduce acid reflux by changing when and how you eat, adjusting your sleep position, and using over-the-counter medications when lifestyle changes aren’t enough. Most people see noticeable improvement within a few weeks of consistent habit changes, and many can manage symptoms without long-term medication.
Acid reflux happens when the muscular valve between your esophagus and stomach (called the lower esophageal sphincter) relaxes at the wrong time or doesn’t close tightly enough. Stomach acid flows backward into the esophagus, causing that familiar burning sensation. The strategies below target different parts of this process.
Foods and Drinks That Make Reflux Worse
Several common foods directly relax the valve at the top of your stomach, making it easier for acid to escape. Coffee, both regular and decaf, relaxes this valve. So do chocolate, peppermint, garlic, and onions. Chocolate contains a compound called methylxanthine, which is chemically similar to caffeine and has the same loosening effect on the valve.
Fatty, spicy, and fried foods are a double problem. They relax the valve and slow stomach emptying, which means food and acid sit in your stomach longer, increasing the window for reflux. You don’t necessarily need to eliminate all of these permanently. Start by cutting the worst offenders for two to three weeks and then reintroduce them one at a time to identify your personal triggers. Many people find they can tolerate small amounts of certain foods but not others.
Citrus fruits, tomato-based sauces, and carbonated drinks are also frequent culprits, though they work differently. Rather than relaxing the valve, they tend to irritate an already-inflamed esophagus or increase stomach pressure.
Timing Your Meals
When you eat matters almost as much as what you eat. Experts recommend stopping all eating and drinking at least three hours before bedtime. This gives your stomach enough time to empty so there’s less acid available to reflux when you lie down. If you eat dinner at 7 p.m. and go to bed at 9, you’re essentially lying down with a full stomach, which is one of the most reliable ways to trigger nighttime symptoms.
Eating smaller, more frequent meals also helps. A large meal stretches the stomach and puts more pressure on the valve. Splitting your usual dinner into two smaller portions, eaten a couple of hours apart, can make a meaningful difference.
How You Sleep Changes Everything
Nighttime reflux tends to be more damaging than daytime reflux because you swallow less during sleep, so acid stays in contact with the esophagus longer. Two changes to your sleep setup can dramatically reduce this.
First, sleep on your left side. A 2022 study in The American Journal of Gastroenterology used real-time monitoring of both sleep position and acid levels in the esophagus. It found that left-side sleeping reduced nighttime reflux more effectively than sleeping on your back or right side. The anatomy explains why: when you lie on your left side, the esophagus and its valve sit higher than the stomach, so gravity helps acid drain back down rather than pooling at the valve.
Second, elevate the head of your bed by 6 to 8 inches. This means raising the legs at the head of the bed frame with blocks or using a wedge pillow. Stacking regular pillows under your head doesn’t work well because it bends your body at the waist, which can actually increase abdominal pressure and make reflux worse. A proper incline keeps your entire upper body elevated.
Breathing Exercises That Strengthen the Valve
This one surprises most people. The diaphragm, the large muscle you use to breathe, wraps around the lower esophageal sphincter and helps keep it closed. Diaphragmatic breathing exercises can strengthen this muscle and improve its ability to act as a barrier against reflux.
The technique is simple: sit or lie down comfortably, place one hand on your chest and one on your belly, and breathe in slowly through your nose so your belly rises while your chest stays relatively still. Exhale slowly through pursed lips. Practice for 5 to 10 minutes, two to three times a day. Research published in Clinical Gastroenterology and Hepatology found that these exercises reduced reflux symptoms even in patients whose symptoms hadn’t fully responded to medication.
Chewing Gum After Meals
Chewing sugar-free gum for 20 to 30 minutes after a meal can help clear acid from the esophagus. Your saliva naturally contains bicarbonate, a mild base that neutralizes acid. Chewing gum stimulates saliva production and encourages more frequent swallowing, which pushes acid back down into the stomach. Bicarbonate-containing gum amplifies this effect. Avoid peppermint-flavored gum, though, since peppermint relaxes the esophageal valve.
Other Habits That Help
Wearing tight clothing, especially around the waist, increases pressure on your stomach and can push acid upward. Opt for looser waistbands if you notice symptoms after meals. Excess weight around the midsection does the same thing on a larger scale. Even modest weight loss of 5 to 10 pounds can reduce reflux frequency in people who are overweight.
If you smoke, that’s worth addressing. Nicotine relaxes the lower esophageal sphincter and reduces saliva production, hitting you from both directions. Alcohol has a similar valve-relaxing effect, particularly wine and spirits.
Avoid bending over or doing heavy lifting right after eating. Both movements increase abdominal pressure when your stomach is full.
When Lifestyle Changes Aren’t Enough
Two main types of over-the-counter medications reduce stomach acid through different mechanisms. H2 blockers (like famotidine) work relatively quickly and are a good option for occasional or mild symptoms. Proton pump inhibitors, or PPIs (like omeprazole), are more powerful but take several days to reach their full effect. PPIs are the standard treatment for frequent reflux, defined as symptoms occurring two or more times per week.
PPIs are highly effective, but guidelines from the American College of Gastroenterology note growing concern about overprescribing them for long-term use. They work best as a defined course of treatment, typically 4 to 8 weeks, rather than an indefinite daily habit. If you find yourself relying on PPIs for months, that’s a signal to revisit your lifestyle strategies or talk with a provider about next steps.
Symptoms That Need Prompt Attention
Most acid reflux is uncomfortable but manageable. Certain symptoms, however, point to complications that need evaluation sooner rather than later. The American Gastroenterological Association identifies these warning signs:
- Difficulty swallowing or a sensation of food getting stuck in your throat or chest
- Unintentional weight loss
- Vomiting blood or material that looks like coffee grounds
- Black or red stools, which can indicate bleeding in the digestive tract
- Chest pain during physical activity, such as climbing stairs
These don’t necessarily mean something serious is wrong, but they warrant investigation to rule out complications like narrowing of the esophagus or changes to the esophageal lining.
