Heartburn stops when you reduce the amount of acid in your stomach or keep that acid from pushing up into your esophagus. You can do both through a combination of dietary changes, body positioning, over-the-counter medications, and a few surprisingly simple habits. The best approach depends on whether you’re dealing with occasional flare-ups or a recurring problem.
Why Heartburn Happens in the First Place
At the bottom of your esophagus sits a ring of muscle that acts like a one-way valve, opening to let food into your stomach and closing to keep acid out. When that valve relaxes at the wrong time or weakens over time, stomach acid escapes upward and burns the lining of your esophagus. That burning sensation behind your breastbone is heartburn.
Anything that relaxes this valve, increases stomach pressure, or ramps up acid production can trigger an episode. The good news: most of those triggers are controllable.
Foods and Drinks That Trigger It
Certain foods directly relax that esophageal valve, making reflux more likely. Coffee, both regular and decaf, is one of the most common culprits. Chocolate contains a compound from the cocoa plant that mimics caffeine and has the same relaxing effect on the valve. Peppermint, garlic, and onions do the same thing.
Fatty, spicy, and fried foods are a double problem: they relax the valve and slow stomach emptying, which means acid sits in your stomach longer with more opportunity to escape. Carbonated drinks work differently. They cause your stomach to bloat with gas, which increases pressure against the valve and forces acid upward.
You don’t necessarily need to eliminate all of these permanently. Start by identifying which ones consistently precede your symptoms, then cut those first.
Lifestyle Changes That Make a Real Difference
Stop eating at least three hours before you lie down. There’s a straightforward physical reason for this: when your stomach is full and you go horizontal, gravity is no longer helping keep acid where it belongs. Giving your stomach time to empty before bed is one of the most effective things you can do for nighttime heartburn.
When you do sleep, elevate the head of your bed to about 30 degrees. A wedge pillow works, or you can raise the head of the bed frame with blocks. Simply stacking pillows tends to bend you at the waist rather than creating a true incline, which can actually make things worse. Sleeping on your left side also helps, and combining left-side sleeping with the incline is more effective than either alone.
If you carry extra weight, especially around the midsection, that added pressure on your stomach pushes acid upward. Even modest weight loss can reduce heartburn frequency significantly.
Quick Fixes That Work Right Now
Antacids containing calcium carbonate (the active ingredient in Tums and Rolaids) neutralize stomach acid on contact, providing relief within minutes. They’re the fastest option but wear off relatively quickly, usually within an hour or two. They work best for occasional, predictable heartburn, like after a heavy meal.
Chewing gum after eating is a lesser-known remedy with real science behind it. Chewing increases your saliva production, and saliva naturally contains bicarbonate, a mild base that neutralizes acid. It also increases swallowing, which pushes escaped acid back down into the stomach. Bicarbonate-containing gum works even better than regular gum, but any sugar-free variety helps.
Baking soda dissolved in water is an old home remedy that genuinely works as a fast-acting antacid. The Mayo Clinic lists a dose of half a teaspoon in a glass of water every two hours, with no more than five teaspoons in a day. However, baking soda is extremely high in sodium, so it’s a poor choice if you have high blood pressure, heart disease, kidney problems, or are pregnant.
Over-the-Counter Medications for Frequent Heartburn
If you get heartburn more than twice a week, antacids alone probably aren’t enough. Two stronger classes of medication are available without a prescription, and they work in fundamentally different ways.
H2 Blockers
These block one of the chemical signals that tells your stomach to produce acid. They work relatively quickly and can be taken as needed, which makes them a good step up from antacids. They reduce acid production rather than just neutralizing what’s already there, so the effect lasts longer.
Proton Pump Inhibitors
PPIs are the strongest acid-suppressing medications available over the counter. They permanently shut down the tiny acid pumps on your stomach cells. Because not all of those pumps are active at the same time, PPIs need to be taken daily for four to eight weeks to reach full effectiveness. They are not designed for immediate relief. It can take one to four days before you notice a difference. You should take them 30 to 60 minutes before your first meal of the day.
For occasional heartburn, an antacid or H2 blocker is usually the right tool. PPIs are designed for persistent, frequent heartburn that hasn’t responded to other approaches.
Concerns About Long-Term Acid Medications
PPIs are safe for short courses, but long-term daily use does carry some considerations. Suppressing stomach acid over months or years can reduce absorption of vitamin B12, magnesium, and calcium. In theory, reduced calcium absorption could affect bone health over time, though for people without existing bone disease risk factors, this isn’t considered a significant concern.
There’s also an association between prolonged PPI use and kidney issues. The current clinical thinking is that this likely starts as an uncommon immune reaction in the kidneys that can progress if unrecognized. For people without pre-existing kidney disease, routine monitoring isn’t considered necessary, but anyone already dealing with kidney problems should use PPIs cautiously and with medical guidance.
The practical takeaway: use PPIs at the lowest effective dose for the shortest time that controls your symptoms. Many people can step down to an H2 blocker or lifestyle changes alone after an initial course.
Ginger as a Natural Option
Ginger speeds up the rate at which your stomach empties, which means food and acid spend less time sitting there with the potential to reflux. Studies have used doses ranging from 400 mg to 3 grams daily, with higher doses of standard ginger powder and lower doses of concentrated extracts both showing benefits for upper digestive symptoms including reflux. A reasonable starting point is about 1,500 mg per day, split across meals. Fresh ginger in cooking or ginger tea counts, though the dose is harder to standardize.
Warning Signs That Need Medical Attention
Most heartburn is uncomfortable but harmless. Certain symptoms, however, suggest something more serious is going on. Difficulty swallowing, unintentional weight loss, and signs of internal bleeding like dark stools or anemia are highly specific warning signs for complications such as esophageal narrowing or, rarely, cancer. Persistent heartburn that doesn’t improve after a full course of PPIs also warrants investigation. Each of these situations calls for an endoscopy to look directly at the esophagus and stomach lining.
