Most indigestion clears up on its own within a few hours, especially if you take a few simple steps to calm your stomach. The discomfort, often felt as bloating, burning, or nausea in your upper abdomen, usually responds well to over-the-counter remedies, dietary changes, and basic positioning tricks. Here’s what actually works, when to try each option, and how to know if something more serious is going on.
Fast Relief Options
If you’re dealing with indigestion right now, your quickest option is a standard antacid. These work by neutralizing stomach acid directly, and most people feel improvement within minutes. The trade-off is that the relief doesn’t last very long, typically an hour or two.
For longer-lasting relief, H2 blockers (sold as famotidine) take about an hour to kick in but keep working for four to ten hours. They reduce the amount of acid your stomach produces rather than just neutralizing what’s already there. If your indigestion tends to come back throughout the day, an H2 blocker will carry you further than an antacid.
Baking soda is a well-known home remedy that works on the same principle as commercial antacids. The standard dose is half a level teaspoon dissolved completely in four ounces of water, taken every two hours as needed. If you’re on a low-sodium diet, skip this one, as baking soda is pure sodium bicarbonate.
Positioning and Timing Tricks
What you do with your body in the hours after eating matters more than most people realize. Stay upright for at least three hours after a meal. Gravity helps keep stomach contents where they belong, and lying down too soon is one of the most reliable ways to make indigestion worse. If you need to sleep, try lying on your left side. Because of where the stomach sits relative to the esophagus, this position makes it harder for acid to travel upward. Research from Amsterdam UMC also found that when acid does reach the esophagus during left-side sleeping, it drains back into the stomach more quickly.
Elevating the head of your bed by about six inches (using blocks under the legs, not extra pillows) can help if nighttime indigestion is a recurring problem. Pillows alone tend to bend you at the waist, which can actually increase pressure on your stomach.
Foods That Make It Worse
Certain foods are consistently linked to indigestion and acid reflux. The major triggers include:
- Fatty and fried foods, which sit in the stomach longer and increase the chance of acid backing up into the esophagus
- Spicy foods, citrus, tomato sauces, and vinegar, which can intensify heartburn directly
- Chocolate, caffeine, onions, peppermint, carbonated drinks, and alcohol, all of which tend to relax the valve between your stomach and esophagus or stimulate extra acid production
You don’t necessarily need to eliminate all of these permanently. Pay attention to which ones consistently bother you and cut those first. Eating smaller meals also helps, since a full stomach puts more pressure on that valve. The three-to-four-hour gap between your last meal and bedtime is one of the most effective changes you can make if nighttime symptoms are your main issue.
Natural Remedies Worth Trying
Ginger has real evidence behind it for indigestion. It has anti-inflammatory properties and appears to help the stomach empty faster, which addresses one of the core mechanisms behind that heavy, bloated feeling. A clinical trial using 540 mg of standardized ginger supplement twice daily for eight weeks found significant improvements in quality of life for people with ongoing indigestion. You can also try fresh ginger tea or ginger chews for milder, occasional symptoms.
Enteric-coated peppermint oil capsules are another option, particularly if cramping or spasm-like discomfort is part of your indigestion. Peppermint oil relaxes the smooth muscle in the digestive tract by blocking calcium channels in the gut wall. The typical dose studied in trials is 0.2 to 0.4 mL taken three times daily. The enteric coating is important: without it, peppermint oil can relax the valve at the top of your stomach and actually worsen heartburn. Look for capsules specifically labeled “enteric-coated.”
When Over-the-Counter PPIs Make Sense
Proton pump inhibitors, sold over the counter as omeprazole, are the strongest acid-reducing option available without a prescription. They’re designed for frequent heartburn that occurs two or more days per week. Unlike antacids or H2 blockers, PPIs take one to four days to reach full effect, so they’re not a good choice for immediate relief. They work best as a short course to calm things down.
The FDA is clear on the limits: don’t take an over-the-counter PPI for more than 14 days at a time, and don’t repeat a 14-day course more than once every four months unless a doctor tells you to. If you find yourself reaching for them more often than that, it’s a sign your indigestion needs a proper evaluation rather than ongoing self-treatment.
Interestingly, when researchers compared PPIs to H2 blockers specifically for functional dyspepsia (indigestion without a clear structural cause), the difference in effectiveness was modest. A Cochrane review found PPIs were only slightly better, and the evidence quality was low. For many people, H2 blockers do the job without the stricter usage limits.
Symptoms That Need Medical Attention
Occasional indigestion after a big meal is normal. But certain symptoms signal that something beyond simple indigestion may be going on. These are considered alarm features that typically prompt a doctor to order an endoscopy or further testing:
- Difficulty swallowing or pain when swallowing
- Unintentional weight loss
- Persistent vomiting
- Signs of gastrointestinal bleeding, such as vomiting blood or dark, tarry stools
- Unexplained iron deficiency anemia (you might notice unusual fatigue or pallor)
- A family history of upper GI cancer
Indigestion that doesn’t improve after two weeks of consistent self-care, or that keeps coming back over several months, also warrants a medical visit. The goal isn’t just symptom relief at that point. It’s making sure there isn’t an ulcer, an infection with H. pylori bacteria, or another treatable cause driving the problem. Most of the time the answer is reassuring, but getting checked means you’re treating the right thing.
