Several things can help with heartburn, from quick fixes like antacids to longer-term habits like changing when and what you eat. The right approach depends on whether you need relief right now or want to stop heartburn from coming back. Most people benefit from a combination of both.
Fast-Acting Options for Immediate Relief
If heartburn is already burning, antacids are the fastest over-the-counter option. They work by directly neutralizing stomach acid, and most people feel relief within minutes. The downside is that the effect wears off relatively quickly, usually within an hour or two.
A simple home remedy works on the same principle: half a teaspoon of baking soda dissolved in a 4-ounce glass of water. Baking soda is sodium bicarbonate, the same active ingredient found in some commercial antacids. It temporarily neutralizes excess stomach acid. Take it one to two hours after eating and at least two hours apart from any other medications. This is a short-term fix, not something to rely on regularly, since the sodium content adds up.
Chewing gum is a surprisingly effective trick. It increases your saliva production, and saliva naturally contains bicarbonate, which neutralizes acid. Each swallow delivers a small dose of that buffer down into your esophagus. In one study, 92% of participants saw their esophageal pH rise toward neutral levels during gum chewing. Sugar-free gum works fine, and bicarbonate-containing gum works even better if you can find it.
Over-the-Counter Medications That Last Longer
When antacids aren’t cutting it, two stronger categories of medication are available without a prescription: H2 blockers and proton pump inhibitors (PPIs). Both reduce the amount of acid your stomach produces rather than just neutralizing what’s already there.
H2 blockers suppress acid production for about eight hours. They’re a good middle ground: stronger than antacids, with a reasonable duration of action. You can take them before a meal you suspect will cause trouble or at bedtime to prevent overnight symptoms.
PPIs are the most powerful option. They reduce stomach acid for 15 to 21 hours per day, but they’re slower to kick in. It can take up to four days to feel the full effect. For best results, take them 30 to 60 minutes before a meal. PPIs are designed for people dealing with frequent heartburn (two or more days per week), not for occasional flare-ups where faster-acting options make more sense.
Foods That Trigger Heartburn
Certain foods relax the muscular valve between your esophagus and stomach, allowing acid to splash upward. They also slow digestion, which means food sits in your stomach longer and produces more acid. The most common culprits, according to Johns Hopkins Medicine, are:
- Fried food
- Fast food
- Pizza
- Potato chips and processed snacks
- Chili powder, black pepper, white pepper, and cayenne
- Fatty meats like bacon and sausage
- Cheese
You don’t necessarily need to eliminate all of these permanently. Pay attention to which ones consistently cause problems for you. Some people can handle moderate spice but react strongly to greasy food, or vice versa. The pattern is more useful than a blanket ban.
When and How You Eat Matters
Meal timing has a significant impact on heartburn, especially at night. Lying down with a full stomach is one of the most reliable ways to trigger reflux, because gravity is no longer helping keep acid where it belongs. Eating your last meal at least three hours before bed is the standard advice, but research suggests that a gap of four to six hours is even more effective for people with stubborn nighttime symptoms. Making dinner the smaller meal of the day, rather than the largest, also helps reduce the volume of food and acid sitting in your stomach overnight.
Eating smaller portions in general puts less pressure on that valve between your esophagus and stomach. A large meal stretches the stomach and can force the valve open. If you tend to eat two or three big meals, splitting them into four or five smaller ones throughout the day can make a noticeable difference.
Sleep Position and Nighttime Habits
Elevating the head of your bed by about six inches helps prevent acid from traveling up your esophagus while you sleep. This means raising the bed frame itself or using a wedge pillow, not just stacking regular pillows (which tends to bend you at the waist and can actually make things worse by compressing your stomach).
Sleeping on your left side also helps. Your stomach curves in a way that, when you’re on your left, the opening to your esophagus sits above the pool of acid. Roll onto your right side and that geometry reverses, making reflux more likely. Combining a raised bed head with left-side sleeping is one of the most effective non-medication strategies for overnight heartburn.
Other Habits That Reduce Heartburn
Tight clothing around your midsection, including belts, waistbands, and shapewear, increases abdominal pressure and can push acid upward. Loosening your waistband after a meal is a small change that genuinely helps. Excess body weight has a similar effect: it increases pressure on the stomach, which is why even modest weight loss often improves reflux symptoms.
Smoking weakens the valve between your esophagus and stomach over time, and alcohol relaxes it in the short term. Both are well-established heartburn triggers. Carbonated drinks can also cause problems by increasing stomach pressure with trapped gas.
Heartburn vs. Something More Serious
Heartburn and heart attacks can feel remarkably similar. Even experienced doctors sometimes can’t tell the difference without testing. Typical heartburn produces a burning sensation in the chest, often after eating or when lying down, and usually improves with antacids. It may come with a sour taste in your mouth or a small amount of stomach contents rising into the back of your throat.
Heart attack symptoms are more likely to involve pressure, tightness, or a squeezing sensation that spreads to your neck, jaw, or back. Shortness of breath, cold sweat, sudden dizziness, and unusual fatigue are additional warning signs. Women are more likely than men to experience jaw or back pain, nausea, and shortness of breath rather than classic chest pain. If your chest discomfort comes with any of these additional symptoms, or if it doesn’t respond to antacids and feels different from your usual heartburn, treat it as an emergency.
