Most heartburn episodes respond well to a combination of quick fixes and simple habit changes. The burning sensation happens when stomach acid backs up into your esophagus, irritating its lining. Whether you’re dealing with an occasional flare-up after a heavy meal or a pattern that keeps coming back, there are effective steps you can take right now and longer-term adjustments that prevent it from returning.
Quick Relief for Active Heartburn
Over-the-counter antacids that contain calcium carbonate (like Tums or Maalox) work within minutes by neutralizing stomach acid directly. They’re a solid first option for occasional heartburn. If antacids alone aren’t cutting it, acid-reducing medications called H2 blockers lower acid production for several hours and can be taken before meals you expect will cause trouble.
A surprisingly effective trick: chew a piece of sugar-free gum for 20 to 30 minutes after eating. Chewing stimulates saliva production, and saliva naturally contains bicarbonate, which buffers acid. The extra saliva also helps wash acid back down out of the esophagus and dilute whatever remains. Choose a non-mint flavor, since mint can actually make reflux worse.
Baking soda dissolved in water is a classic home remedy that does work as a short-term antacid. Half a teaspoon in a glass of cold water can neutralize acid quickly. But there are real limits to this approach: don’t use it for more than two weeks, don’t take it within one to two hours of other medications (it can interfere with absorption), and avoid it entirely if you’re on a sodium-restricted diet or have high blood pressure, kidney disease, or heart problems. It contains a large amount of sodium per dose.
Foods and Drinks That Trigger Heartburn
Certain foods relax the muscular valve at the bottom of your esophagus, the one responsible for keeping acid in your stomach where it belongs. When that valve loosens, acid escapes upward. The most common culprits are alcohol, chocolate, coffee, high-fat foods, and mint (especially peppermint). These don’t just irritate on the way down. They physically weaken the valve’s ability to stay closed.
Carbonated drinks cause a different problem. Sodas and seltzers create pressure inside the stomach that forces the valve open, even if it’s functioning normally. If heartburn is a regular issue for you, cutting back on carbonation is one of the easier wins. You don’t necessarily need to eliminate every trigger food permanently, but identifying which ones consistently cause your symptoms lets you make targeted choices rather than overhauling your entire diet.
Meal Timing and Portion Size
One of the most effective changes has nothing to do with what you eat. Stop eating at least three hours before lying down. When you’re upright, gravity helps keep stomach contents where they belong. Lie down with a full stomach and acid has an easy path into your esophagus. This three-hour window gives your stomach enough time to empty significantly before sleep.
Large meals also increase the pressure inside your stomach, which pushes acid upward. Eating smaller, more frequent meals throughout the day puts less strain on that esophageal valve than loading up at dinner. If you tend to eat one or two big meals, splitting them into three or four smaller ones can noticeably reduce episodes.
How You Sleep Matters
Elevating the head of your bed by 6 to 8 inches (using a wedge pillow or blocks under the bed frame, not just extra pillows) helps gravity work in your favor overnight. Stacking regular pillows tends to bend you at the waist, which can actually increase abdominal pressure.
Your sleep position also makes a measurable difference. A study published in The American Journal of Gastroenterology monitored 57 people with chronic heartburn and found that while acid escaped into the esophagus roughly the same number of times regardless of position, it cleared much faster when people slept on their left side compared to their right side or back. Faster clearance means less time acid spends in contact with esophageal tissue, which means less pain and less risk of damage over time. If you’re a right-side sleeper and deal with nighttime heartburn, switching to your left is worth trying.
Other Lifestyle Changes That Help
Tight clothing around your midsection, including belts, waistbands, and shapewear, increases abdominal pressure and can push acid upward. Wearing looser-fitting clothes, especially after meals, removes that mechanical pressure.
Excess weight, particularly around the abdomen, has the same effect on a larger scale. Even modest weight loss can reduce the frequency and severity of heartburn by lowering the constant pressure on your stomach. Smoking also weakens the esophageal valve, so quitting addresses heartburn alongside its many other health benefits.
Heartburn During Pregnancy
Heartburn is extremely common during pregnancy, driven by hormonal changes that relax the esophageal valve and physical pressure from the growing uterus. Calcium-based antacids are generally considered a safe first option, but the timing matters. The risk of harm to the fetus tends to be highest during the first trimester, and safety depends on the specific ingredients in the product. Some antacids are fine in small amounts while others should be avoided completely. Talk to your provider before starting any heartburn medication during pregnancy, even over-the-counter ones.
When Heartburn Becomes Something More
Occasional heartburn is normal. But if you’re experiencing it two or more times a week, that pattern meets the clinical definition of gastroesophageal reflux disease (GERD). Left untreated over time, GERD can damage the esophageal lining and, in some cases, lead to precancerous changes called Barrett’s esophagus. If you’re reaching for over-the-counter products more than twice a week, that’s a signal to get a proper evaluation rather than continuing to self-treat.
Stronger prescription medications can suppress acid production more effectively than anything available over the counter. These work well for many people, but long-term use carries its own considerations, including potential effects on bone density, certain nutrient absorption, and gut bacteria balance. That’s not a reason to avoid them if you need them, but it is a reason to have a doctor periodically reassess whether continued use is still necessary rather than simply refilling indefinitely.
Certain symptoms alongside heartburn warrant prompt medical attention: difficulty swallowing, pain when swallowing, unexplained weight loss, vomiting blood, or black or bloody stools. These are considered alarm symptoms that typically call for a direct look at the esophagus and stomach to rule out more serious problems.
