Most heartburn responds well to simple changes you can make right now, no prescription needed. The burning sensation happens when stomach acid escapes upward into your esophagus, usually because the muscular valve between your stomach and esophagus relaxes at the wrong time or doesn’t close tightly enough. The good news: adjusting when, what, and how you eat, along with a few positional tricks, can dramatically reduce how often this happens.
Why Heartburn Happens
At the bottom of your esophagus sits a ring of muscle that acts like a one-way gate. It opens to let food drop into your stomach, then squeezes shut to keep acid from splashing back up. Heartburn occurs when this gate malfunctions, either by relaxing too frequently or by not maintaining enough baseline pressure to stay closed.
The problem is primarily one of nerve signaling rather than raw muscle weakness. Your diaphragm also plays a supporting role, acting like an external clamp around that valve. Anything that increases pressure inside your stomach (a large meal, tight clothing, bending over) or weakens the valve’s seal (certain foods, body position) tips the balance toward acid escaping upward.
Foods and Drinks That Make It Worse
Certain foods relax that esophageal valve or increase acid production directly. The most reliable triggers include chocolate, caffeine, peppermint, alcohol, and carbonated drinks. Fatty and fried foods are especially problematic because they sit in the stomach longer, giving acid more time and more opportunity to push upward.
Spicy foods, citrus, tomato-based sauces, onions, and vinegar don’t necessarily cause more acid production, but they can intensify the burning sensation when acid does reach your esophagus. You don’t need to eliminate every item on this list permanently. Pay attention to which ones consistently bother you and cut back on those first.
Meal size matters as much as meal content. A large meal physically stretches the stomach and increases internal pressure, which pushes acid toward the valve. Eating smaller, more frequent meals reduces that pressure and gives your stomach less work to do at any one time.
Timing Your Last Meal
One of the most effective changes you can make is simply not eating close to bedtime. A study comparing nearly 150 reflux patients with almost 300 healthy controls found that eating dinner less than three hours before bed significantly increased reflux risk compared to waiting four hours or more. Separate research using esophageal pH monitoring found that people who ate within two hours of lying down were about 2.5 times more likely to experience reflux than those who waited longer.
Aim for at least three hours between your last meal and the time you lie down. If you need a late snack, keep it small and avoid known trigger foods.
How You Sleep Changes Everything
Gravity is your best overnight ally. Elevating the head of your bed, or using a wedge pillow angled between 30 and 45 degrees (raising your head six to twelve inches), keeps acid pooled in your stomach where it belongs. Stacking regular pillows under your head doesn’t work as well because it bends you at the neck rather than tilting your whole torso.
Sleeping on your left side also helps. The American Gastroenterological Association recommends this position because of how the stomach and esophagus are anatomically arranged. When you lie on your left, the junction where your esophagus meets your stomach sits above the level of stomach acid. Roll to your right side and that relationship flips, making it easier for acid to reach the valve. Combining left-side sleeping with head elevation is the most effective nighttime strategy.
Quick Relief With Baking Soda
Baking soda (sodium bicarbonate) is a true antacid that neutralizes stomach acid on contact. Dissolving half a teaspoon in a glass of water can bring fast relief during an active episode. The maximum safe amount is about five teaspoons of the effervescent powder form per day, but most people need far less than that.
There are real limits to this approach. Don’t use baking soda for more than two weeks straight. It contains a large amount of sodium, so it’s a poor choice if you’re watching your salt intake or managing high blood pressure, kidney disease, heart disease, or swelling in your legs. It can also interfere with other medications, so avoid taking it within one to two hours of any other oral medicine. Think of baking soda as an occasional rescue tool, not a daily habit.
Chewing Gum After Meals
Chewing sugar-free gum for 20 to 30 minutes after eating is a surprisingly effective trick. The chewing motion stimulates saliva production, and saliva is naturally rich in bicarbonate, the same compound that makes baking soda work. This bicarbonate-rich saliva washes down the esophagus, neutralizing any acid that’s crept upward and clearing it back toward the stomach. Extended chewing prolongs the effect, offering sustained relief rather than a quick fix. Stick with non-mint flavors, since peppermint can relax the esophageal valve.
Other Habits That Help
Wearing loose-fitting clothing around your midsection reduces external pressure on your stomach. This sounds minor, but tight belts and waistbands physically compress the abdomen and push acid upward.
If you smoke, reflux is one more reason to quit. Nicotine relaxes the esophageal valve directly. Excess body weight, particularly around the abdomen, creates constant upward pressure on the stomach. Even modest weight loss can noticeably reduce heartburn frequency for people carrying extra weight in that area.
After eating, stay upright. Take a walk, do dishes, sit comfortably, but don’t lie down on the couch or bend over to do floor-level tasks. Keeping your torso vertical lets gravity do the work of keeping acid where it belongs.
A Note About Ginger
Ginger is widely recommended online for heartburn, but the evidence is mixed at best. While ginger does speed up gastric emptying (moving food out of your stomach faster), it also relaxes the esophageal valve, which could make reflux worse. Research suggests that consuming six grams or more of ginger may actively worsen heartburn and gastrointestinal discomfort. If you want to try ginger tea for mild symptoms, keep the amount small and stop if it makes things worse.
Over-the-Counter Antacids
Standard antacids available at any pharmacy neutralize acid quickly and provide short-term relief. They work well for occasional heartburn but aren’t meant for daily use. If you find yourself reaching for antacids every day, that’s a signal to look deeper into what’s causing the problem rather than continuing to mask it. Stronger acid-reducing medications are available over the counter as well, but frequent heartburn warrants a conversation with a healthcare provider to rule out underlying conditions.
When Heartburn Might Be Something Else
Heartburn and heart attacks can feel remarkably similar. Even experienced doctors sometimes can’t distinguish them based on symptoms alone. Typical heartburn produces a burning sensation in the chest, usually after eating or while lying down, often with a sour taste in the mouth. It generally responds to antacids.
Heart attack symptoms tend to feel more like pressure, tightness, or squeezing in the chest or arms, sometimes radiating to the neck, jaw, or back. Shortness of breath, cold sweat, sudden dizziness, and unusual fatigue are warning signs that point away from simple heartburn. But heart attacks don’t always follow the textbook pattern. They can mimic indigestion closely, and the pain doesn’t have to be severe or long-lasting to be dangerous. If your chest discomfort comes with any of these additional symptoms, or if something simply feels different from your usual heartburn, call emergency services immediately.
