Heartburn usually responds well to a combination of simple habit changes, over-the-counter medications, and dietary adjustments. For occasional flare-ups, an antacid can neutralize stomach acid within minutes. For heartburn that keeps coming back, the fixes that matter most are when and how much you eat, what you eat, and how you position your body afterward.
Quick Relief: Over-the-Counter Medications
Three classes of medication target heartburn, and they work on different timelines. Antacids (like calcium carbonate tablets) neutralize acid that’s already in your stomach and bring relief within minutes, but the effect wears off relatively quickly. They’re best for occasional, predictable heartburn, like after a heavy meal.
H2 blockers reduce acid production by blocking one of the chemical signals that tells your stomach to make acid. They take longer to kick in than antacids but keep working for about eight hours, making them useful if you know a trigger is coming, like a late dinner.
Proton pump inhibitors (PPIs) shut down the acid-producing pumps in your stomach lining more directly and provide the longest relief, reducing acid for 15 to 21 hours a day. The tradeoff is speed: PPIs can take up to four days to reach full effect, so they’re designed for frequent heartburn rather than a single episode. Long-term PPI use has been linked to potential side effects including weakened bones, certain nutrient deficiencies, and a higher risk of gut infections, so it’s worth reassessing periodically whether you still need them.
Eating Habits That Reduce Flare-Ups
A large meal increases pressure inside your stomach and pushes acid upward toward your esophagus. Eating smaller, more frequent meals throughout the day is one of the most consistently effective changes you can make. Late-night eating is another major trigger. When you lie down with a full stomach, gravity can no longer help keep acid where it belongs. Finishing your last meal at least two to three hours before bed gives your stomach time to empty.
Certain foods are more likely to provoke heartburn: citrus, tomato-based sauces, chocolate, coffee, alcohol, fried or fatty foods, and peppermint. You don’t necessarily need to eliminate all of them. Pay attention to which ones consistently bother you and cut those first.
Foods That Calm Heartburn
Some foods actively help counteract acid. Alkaline foods, those higher on the pH scale, can offset stomach acid. Good options include bananas, melons, cauliflower, fennel, and nuts. Foods with high water content also help by diluting stomach acid: celery, cucumber, lettuce, watermelon, broth-based soups, and herbal teas all fall into this category.
Ginger is one of the more reliable natural digestive aids. It’s alkaline and has anti-inflammatory properties that soothe irritation in the digestive tract. Sipping ginger tea at the first sign of heartburn can help settle things down. Nonfat milk and low-fat yogurt can also act as a temporary buffer between your stomach lining and acid, providing quick but short-lived relief.
A small amount of lemon juice mixed with warm water and honey, despite lemon being acidic on its own, has a mild alkalizing effect once metabolized and may help neutralize stomach acid for some people.
Sleep Position Matters
If heartburn wakes you up at night, how you sleep can make a real difference. Sleeping on your left side positions your stomach below your esophagus, making it harder for acid to travel upward. Research from Amsterdam UMC confirmed that this position measurably reduces acid reflux episodes during sleep.
Elevating the head of your bed also helps. Propping up just your head with extra pillows can actually make things worse by bending your body at the waist and increasing abdominal pressure. Instead, raise the entire head of your bed using blocks under the legs or a foam wedge under your mattress so your torso is on a gentle incline.
Herbal and Natural Options
Chamomile tea may have a soothing effect on the digestive tract, though if you have a ragweed allergy, you could react to it. Deglycyrrhizinated licorice (DGL), available as pills or liquid, is thought to work by increasing the protective mucus coating on your esophageal lining, helping it resist acid damage. DGL shouldn’t be used regularly, though, because excessive licorice intake can raise blood pressure.
Baking soda (sodium bicarbonate) is a classic home remedy that neutralizes acid quickly. The typical dose for heartburn relief is one to two and a half teaspoons dissolved in a glass of cold water after meals, with a daily maximum of five teaspoons. However, baking soda is very high in sodium. If you have high blood pressure, heart disease, kidney disease, or are on a sodium-restricted diet, it’s not a safe option. It should also be avoided during pregnancy complications and never given to children under six.
Heartburn vs. Heart Attack
Heartburn and heart attacks can feel disturbingly similar. Even experienced doctors sometimes can’t tell them apart from symptoms alone. Typical heartburn causes a burning sensation in the chest or upper abdomen, usually after eating or while lying down. It’s often accompanied by a sour taste in the mouth or a small amount of stomach contents rising into the throat, and it generally improves with antacids.
A “textbook” heart attack involves sudden, crushing chest pain and difficulty breathing, often triggered by physical exertion. But many heart attacks don’t follow the textbook. If your chest pain feels like tightening or squeezing, spreads to your arm, jaw, or back, or comes with shortness of breath, sweating, or lightheadedness, treat it as a cardiac emergency.
Signs Your Heartburn Needs Medical Attention
Occasional heartburn after a big meal is normal. But certain patterns signal something more serious. You should see a healthcare provider if you experience heartburn on a weekly basis, have difficulty swallowing or are losing weight unintentionally, notice that antacids and lifestyle changes aren’t making a difference, or feel chest pain that resembles tightening or squeezing rather than burning. Adults over 60 with new or worsening heartburn also warrant a closer look, since the risk of complications from chronic reflux increases with age.
