Most indigestion clears up with a combination of simple dietary changes, over-the-counter medication, and adjusting when and how you eat. The burning, bloating, or upper-belly pain you’re feeling is usually triggered by something identifiable, and once you pin it down, relief comes quickly. For occasional episodes, an antacid can work within minutes. For recurring symptoms, a more systematic approach pays off.
What’s Actually Happening in Your Stomach
Indigestion, or dyspepsia, is an umbrella term for discomfort centered in your upper abdomen. The core symptoms include feeling uncomfortably full after eating, getting full too quickly during a meal, a burning sensation in the upper belly, and pain between your navel and breastbone. These can show up together or alone.
Several things can set it off. High-fat meals, alcohol, chocolate, and carbonated drinks physically relax the muscular valve between your esophagus and stomach, letting acid splash upward. Certain foods, especially spicy dishes, citrus, tomatoes, onions, garlic, and mint, directly irritate the stomach lining. Eating too fast or too much raises pressure inside the stomach and slows digestion, which compounds the problem. NSAIDs like ibuprofen are another common culprit, since they weaken the stomach’s protective lining.
Sometimes there’s no clear structural cause. When symptoms persist for at least three months without an identifiable reason, it’s classified as functional dyspepsia, a condition where the stomach’s nerves and muscles aren’t coordinating properly even though nothing looks abnormal on a scope.
Dietary and Lifestyle Fixes That Work
Before reaching for medication, adjusting your habits can eliminate symptoms entirely for many people. These changes are also the foundation that makes medication more effective if you do need it.
Eat smaller meals more frequently rather than three large ones. Large meals distend the stomach, increase pressure, and slow emptying. Avoid your personal trigger foods. The most common offenders are fried or greasy foods, carbonated drinks, coffee, alcohol, chocolate, and acidic fruits like oranges and tomatoes. You don’t necessarily need to cut all of them permanently. Try eliminating the most likely culprits for two to three weeks, then reintroduce them one at a time to identify your specific triggers.
Timing matters enormously. Eating dinner less than three hours before lying down is strongly linked to reflux symptoms. One study found that people who ate within three hours of bedtime had over seven times the odds of experiencing reflux compared to those who waited four hours or more. If you can’t push dinner earlier, at least stay upright afterward, whether that means a walk, doing dishes, or sitting on the couch rather than reclining. Elevating the head of your bed by about six inches (using blocks under the legs, not extra pillows) also helps keep acid where it belongs overnight.
Loose-fitting clothing around your midsection, maintaining a healthy weight, and not smoking all reduce the mechanical pressure on your stomach that contributes to symptoms.
Over-the-Counter Medications
When lifestyle changes aren’t enough on their own, three categories of OTC medications target indigestion in different ways.
Antacids
Antacids (brands like Tums, Rolaids, and Maalox) neutralize acid that’s already in your stomach. They work within minutes, making them ideal for occasional flare-ups or breakthrough symptoms. The relief typically lasts 30 to 60 minutes. They’re a good first choice for mild or infrequent indigestion, but they won’t prevent symptoms from returning.
H2 Blockers
H2 blockers reduce the amount of acid your stomach produces. Famotidine (Pepcid) is the most widely available option. These take longer to kick in than antacids, usually 30 to 60 minutes, but provide longer-lasting relief, often up to 12 hours. They work well when you know a trigger is coming, like a rich meal, and can be taken preventively. They’re also a reasonable step up when antacids alone aren’t cutting it.
Proton Pump Inhibitors
PPIs like omeprazole (Prilosec) and lansoprazole (Prevacid) are the strongest acid reducers available without a prescription. They block acid production at the source and are most effective when taken 30 to 60 minutes before breakfast. PPIs aren’t designed for instant relief. They build up over several days, so they’re best suited for recurring symptoms rather than a one-off episode.
Here’s the important caveat: PPI prescriptions lasting more than eight weeks are generally not recommended unless a doctor is actively managing your care. Long-term use has been linked to reduced iron and calcium absorption, a higher risk of gut infections (including a 69% increase in odds of recurrent C. difficile infection), disruption of healthy gut bacteria, and in some studies, a small but meaningful increase in overall mortality risk. These aren’t reasons to avoid PPIs when you need them, but they are reasons not to stay on them indefinitely without medical oversight. If you’ve been taking a PPI daily for months, it’s worth having that conversation with your doctor.
Natural Remedies Worth Trying
Peppermint oil has the most research behind it for functional digestive complaints. It works by relaxing smooth muscle in the digestive tract, reducing sensitivity to pain signals, and calming inflammation. Most clinical trials have used enteric-coated peppermint oil capsules (the coating prevents the oil from releasing in the stomach, where it could actually worsen reflux) combined with caraway oil. The combination has performed well in randomized controlled trials for functional dyspepsia, though peppermint oil alone hasn’t been tested as rigorously for this specific condition.
Ginger is widely used for nausea and has some evidence supporting its use for general stomach discomfort, though the data is stronger for nausea prevention than for dyspepsia specifically. A cup of ginger tea before or after meals is low-risk and may help.
The H. Pylori Question
If your indigestion keeps coming back despite lifestyle changes and medication, a bacterial infection called H. pylori could be the underlying cause. This bacterium infects the stomach lining and can cause chronic inflammation, ulcers, and persistent dyspepsia. For people without alarm symptoms (more on those below), a simple breath test or stool test is the recommended first step rather than jumping straight to an endoscopy. If H. pylori is found, a course of antibiotics typically resolves the infection and, with it, the symptoms.
Your personal history matters here too. A family history of stomach ulcers or gastric cancer, regular NSAID use, and your age all factor into how aggressively your doctor might investigate recurring symptoms.
Indigestion During Pregnancy
Pregnancy-related indigestion is extremely common, driven by hormonal changes that relax the valve between the esophagus and stomach and the physical pressure of a growing uterus. Treatment follows a step-up approach: start with lifestyle modifications (smaller meals, no eating before bed, sleeping propped up), then move to pharmacological options only if needed.
The first medication recommended is calcium-containing antacids like Tums, which carry the strongest safety rating for pregnancy. If antacids alone aren’t controlling symptoms, sucralfate (a prescription medication that coats the stomach lining) can be added. The next step up is combining antacids with an H2 blocker. PPIs are reserved for cases where nothing else works. This stepwise approach minimizes fetal medication exposure while still providing relief.
Symptoms That Need Medical Attention
Most indigestion is uncomfortable but harmless. Certain symptoms, however, signal something more serious. The American College of Gastroenterology identifies these as alarm symptoms that warrant prompt evaluation:
- Unintentional weight loss you can’t explain
- Difficulty swallowing or pain when swallowing
- Persistent vomiting that doesn’t resolve
- Unexplained anemia (you might notice fatigue or pallor)
- A family history of upper gastrointestinal cancer
If you’re 60 or older and experiencing new or worsening indigestion, current guidelines recommend an upper endoscopy regardless of whether alarm symptoms are present. For people under 60, the endoscopy is recommended only when alarm symptoms appear. Age matters because the risk of serious underlying causes increases significantly after 60, even when symptoms seem routine.
