You can stop most acid reflux episodes by changing when, what, and how you eat, adjusting your sleep position, and using the right over-the-counter medication when needed. For many people, reflux is driven by a handful of identifiable triggers, and eliminating even one or two can make a noticeable difference. The key is understanding what’s actually happening: a ring of muscle at the bottom of your esophagus (called the lower esophageal sphincter) relaxes when it shouldn’t, letting stomach acid flow upward. Nearly everything on this list works by either keeping that muscle closed or reducing the amount of acid available to escape.
Cut the Foods That Relax Your Esophageal Valve
Certain foods cause that lower valve to loosen, and others slow digestion so food sits in your stomach longer, building pressure. The biggest offenders are foods high in fat, salt, or spice: fried food, fast food, pizza, bacon, sausage, cheese, and processed snacks like potato chips. These delay stomach emptying and give acid more time and reason to push upward.
A second group of triggers works differently. Chocolate, peppermint, and carbonated beverages directly relax the valve muscle. Tomato-based sauces and citrus fruits are highly acidic on their own, which irritates an already-sensitive esophagus. You don’t necessarily need to eliminate all of these permanently. Start by removing the two or three you consume most often, then reintroduce them one at a time to identify your personal triggers.
Stop Eating 2 to 3 Hours Before Bed
Lying down with a full stomach is one of the most reliable ways to trigger nighttime reflux. Gravity is no longer helping keep acid in your stomach, and a recent meal means more acid is being produced. Experts recommend waiting at least two to three hours after eating solid food before you lie down. For drinks, a minimum of 30 minutes is a reasonable guideline. This single change often eliminates nighttime symptoms entirely for people with mild to moderate reflux.
Fix Your Sleep Position
Two adjustments to how you sleep can dramatically reduce overnight acid exposure. First, elevate the head of your bed by 6 to 8 inches using blocks under the bed frame or a wedge under your mattress. Stacking pillows doesn’t work as well because it bends your body at the waist rather than creating a consistent incline, which can actually increase abdominal pressure.
Second, sleep on your left side. When you lie on your left, gravity and the natural position of your stomach relative to your esophagus work together to keep acid pooled away from the valve. Right-side sleeping does the opposite, positioning the stomach above the esophageal opening and making reflux more likely.
Lose Weight Around Your Midsection
Excess abdominal fat physically disrupts the barrier between your stomach and esophagus. Visceral fat (the deep fat surrounding your organs) increases pressure inside your abdomen, which pushes stomach contents upward and increases acid exposure in the esophagus. This is a mechanical problem: more internal pressure means a harder job for that lower valve. Even modest weight loss, particularly around the waist, can reduce reflux frequency. If your symptoms appeared or worsened alongside weight gain, this is likely a major contributing factor.
Try Diaphragmatic Breathing
This one sounds unlikely, but there’s real evidence behind it. The diaphragm wraps around the same area as the lower esophageal valve, and strengthening it can reinforce the anti-reflux barrier. The technique is simple: place one hand on your chest and one on your abdomen, then breathe so that only your abdomen rises while your chest stays still. Your lower hand should move outward with each inhale. A program studied in GERD patients involved 30 of these breaths over 5 minutes, three times a day, in different positions (lying down, sitting, and standing). Patients who followed this routine saw meaningful improvements in symptoms and quality of life.
Wear Loose Clothing
Tight belts, waistbands, and shapewear compress your abdomen and increase pressure on your stomach, the same mechanism that makes excess visceral fat a problem. If you notice reflux is worse when wearing fitted pants or cinched belts, switching to looser clothing around your midsection is a free, immediate fix.
Choose the Right Over-the-Counter Medication
Three categories of acid-reducing medication are available without a prescription, and they work in different ways on different timelines.
Antacids (like Tums or Maalox) neutralize acid that’s already in your stomach. They work within minutes and are best for occasional, predictable symptoms, like after a big meal. Their relief is short-lived.
H2 blockers (like famotidine, sold as Pepcid AC) reduce the amount of acid your stomach produces. They take longer to kick in but provide relief for about eight hours, making them a better choice if you need overnight coverage or know a trigger is coming.
Proton pump inhibitors (like omeprazole, sold as Prilosec) are the strongest option. They suppress acid production for 15 to 21 hours a day but can take up to four days to reach full effect. They’re designed for frequent reflux (two or more episodes per week) and are typically used in 14-day courses, not as one-off treatments.
Long-term PPI use has raised some safety questions. Extended use can interfere with absorption of calcium, magnesium, iron, and vitamin B12, all of which depend on stomach acid for proper uptake. There’s been concern about fracture risk from reduced calcium absorption. Earlier studies suggested links to kidney disease, but more recent analysis suggests those associations were likely coincidental rather than caused by the medication. Still, PPIs work best as a short-term bridge while you put lifestyle changes in place, not as a permanent solution for most people.
Herbal Teas and Home Remedies
Chamomile, ginger, and turmeric teas are popular home remedies, and there’s some biological plausibility behind them. Chamomile has anti-inflammatory properties that may soothe an irritated esophagus, and a 2023 review of functional foods for acid reflux suggested potential benefits from drinking it after meals or before bed. Stress is also a well-established reflux trigger, and chamomile tea’s calming effect could help indirectly by lowering stress levels. That said, no clinical trials have confirmed that chamomile directly reduces reflux symptoms. These teas are safe for most people and worth trying, but they shouldn’t replace the changes that have stronger evidence behind them.
Symptoms That Need Medical Attention
Most reflux responds well to the strategies above. But certain symptoms signal something more serious. Difficulty swallowing, the sensation that food is getting stuck in your throat or chest, unexplained weight loss, or frequent vomiting alongside reflux all warrant a visit to a gastroenterologist. If a blockage ever makes it hard to breathe, that’s an emergency. These red flags can indicate narrowing of the esophagus, severe inflammation, or other conditions that need direct evaluation rather than self-management.
