Most indigestion resolves on its own or with simple changes to how and what you eat. The burning, bloating, or upper belly discomfort you’re feeling is usually your stomach reacting to something temporary: a heavy meal, eating too fast, or a food that relaxes the valve between your stomach and esophagus. Here’s how to get relief now and prevent it from coming back.
Quick Relief Options
If you need relief right now, over-the-counter options fall into three categories, and they work on different timelines. Antacids (the chewable tablets or liquids you’ll find at any pharmacy) neutralize stomach acid on contact and kick in within minutes. The tradeoff is that they wear off relatively quickly. H2 blockers take about an hour to work but keep symptoms suppressed for 4 to 10 hours. Proton pump inhibitors (PPIs) are the slowest to start, sometimes taking one to four days to reach full effect, but they provide the longest-lasting relief.
For occasional indigestion after a big meal, antacids are usually enough. If you find yourself reaching for them regularly, an H2 blocker gives you a longer window of comfort. PPIs are better suited for persistent acid problems rather than one-off episodes.
Baking Soda as a Quick Fix
Plain baking soda (sodium bicarbonate) is an effective, cheap antacid you may already have in your kitchen. The standard dose for adults is half a teaspoon dissolved in a full glass of cold water, taken after meals. Don’t exceed five teaspoons in a single day.
This is strictly a short-term remedy. The Mayo Clinic advises against using baking soda for more than two weeks. Repeated or high-dose use can cause side effects, and people with kidney disease are at higher risk of complications. If your indigestion keeps returning, that’s a signal to look at the underlying cause rather than keep neutralizing acid.
Foods That Make It Worse
Certain foods relax the muscular valve at the top of your stomach, allowing acid to splash back into the esophagus. Others slow down digestion, leaving food sitting in your stomach longer than it should. Both effects trigger that familiar burning or heavy feeling.
The biggest offenders are high-fat, high-salt, and heavily spiced foods: fried food, fast food, pizza, bacon, sausage, cheese, and processed snacks like potato chips. Tomato-based sauces, citrus fruits, chocolate, peppermint, and carbonated drinks can also cause problems. Even milk, which people sometimes drink to soothe a burning stomach, can backfire because of its fat content. If you drink milk for comfort, switching to a lower-fat version may help.
You don’t necessarily need to eliminate all of these permanently. Pay attention to which specific foods trigger your symptoms and reduce those first. Many people find that cutting back on fried and fatty foods makes the biggest difference.
How You Eat Matters Too
Eating speed plays a surprisingly large role in indigestion. When you eat quickly, you swallow more air, chew food less thoroughly, and give your body less time to register fullness. Slower eating increases the release of hormones that signal satiety, which means you’re less likely to overeat, and your stomach has an easier time breaking down food that’s been chewed more completely.
A few practical changes that help: put your fork down between bites, aim for smaller and more frequent meals instead of two or three large ones, and stop eating before you feel stuffed. Eating your last meal at least two to three hours before lying down gives your stomach time to empty, reducing the chance of acid creeping upward.
Posture and Sleep Position
Gravity is a simple but effective tool against indigestion. Staying upright after eating lets acid drain naturally downward. If you get symptoms at night, elevating the head of your bed by a few inches (using a wedge pillow or blocks under the bedframe) keeps your esophagus above your stomach while you sleep.
Sleeping on your left side also helps, and the reason is anatomical. In that position, your esophagus and the valve at its base sit higher than your stomach, so acid drains away from the esophagus more quickly. Sleeping on your right side does the opposite, positioning the stomach above the valve and making reflux more likely. If nighttime indigestion is a recurring problem, training yourself to sleep on your left side is one of the simplest fixes available.
Peppermint Oil for Digestive Discomfort
Peppermint oil can relieve indigestion by relaxing the smooth muscle in your digestive tract. It works by blocking calcium from entering muscle cells, which reduces cramping and spasms. There’s an important catch, though: that same relaxing effect can loosen the valve at the top of your stomach, potentially making heartburn worse.
The workaround is enteric-coated peppermint oil capsules. These have a special coating that prevents the capsule from dissolving until it reaches your small intestine, bypassing the esophageal valve entirely. This gives you the muscle-relaxing benefits without the heartburn side effect. If your indigestion involves more bloating and cramping than burning, enteric-coated peppermint oil is worth trying.
Other Habits That Help
Tight clothing, especially anything that presses on your abdomen, can push stomach contents upward. Wearing looser pants or skipping the belt a notch after meals sounds trivial, but it makes a real difference for some people. Stress is another common trigger. Your gut has its own extensive nervous system, and anxiety or tension can directly increase acid production and slow digestion. Regular exercise, adequate sleep, and whatever stress management works for you (walking, breathing exercises, spending time outside) all contribute to fewer episodes.
Alcohol and smoking both relax the esophageal valve and irritate the stomach lining. Cutting back on either one often produces noticeable improvement within days.
Signs That Need Medical Attention
Occasional indigestion after a rich meal is normal. But certain symptoms alongside indigestion suggest something more serious is going on. These include difficulty swallowing, unexplained weight loss of more than about 6 or 7 pounds, blood in your stool or black tarry stools, signs of anemia (persistent fatigue, paleness, dizziness), or vomiting blood. Any of these warrants prompt evaluation, typically with an endoscopy to look directly at the lining of your esophagus and stomach.
Age is also a factor. Guidelines generally recommend that people over 50 who develop new, persistent indigestion get an endoscopy to rule out underlying conditions, even without alarm symptoms. And if your indigestion keeps coming back despite the lifestyle changes and remedies above, that pattern itself is worth discussing with a doctor. Recurring symptoms can signal an ulcer, a bacterial infection in the stomach, or a condition that responds well to targeted treatment once it’s properly identified.
