Most indigestion resolves with a combination of simple dietary changes, over-the-counter medications, and adjustments to when and how you eat. The discomfort you’re feeling, whether it’s burning in your upper stomach, bloating after meals, or an uncomfortable fullness that hits before you’ve finished eating, almost always responds to straightforward interventions you can start today.
Start With What You’re Eating
Meals are the single most common trigger for indigestion. Large portions stretch the stomach, and high-fat foods slow digestion, keeping food sitting in your stomach longer than it should. The most consistently supported dietary approach is eating smaller, more frequent meals that are lower in fat. This reduces the amount of stretching your stomach has to do at any one time and lets food move through more efficiently.
Beyond portion size, certain foods and drinks are well-known provocateurs. Coffee, tea, and carbonated drinks can all increase acid production or relax the valve between your stomach and esophagus. Keeping these to two cups or fewer per day makes a measurable difference for many people. Spicy foods, citrus, tomato-based sauces, chocolate, and alcohol round out the usual list of triggers, though your personal list may be shorter or different.
If you notice that bloating and fullness are your main symptoms, especially after meals, a short trial of reducing high-FODMAP foods (certain carbohydrates found in onions, garlic, wheat, beans, and some fruits) can help you identify personal thresholds. This works best with guidance from a dietitian, since the goal isn’t permanent restriction. It’s a process of elimination followed by gradual reintroduction so you learn exactly which foods bother you and how much you can tolerate.
Timing and Habits That Help
When you eat matters almost as much as what you eat. Lying down within two to three hours of a meal lets stomach acid creep upward, worsening that burning sensation. Eating your last meal or snack earlier in the evening gives your stomach time to empty before bed. If nighttime symptoms are a problem, elevating the head of your bed by about six inches (using blocks under the bed frame, not extra pillows) keeps gravity working in your favor.
Regular physical activity, around 30 minutes of moderate-to-vigorous exercise daily, improves how efficiently your digestive system moves food along. Walking after meals is a simple starting point. Eating slowly and chewing thoroughly also reduces the amount of air you swallow, which cuts down on bloating and belching.
Over-the-Counter Medications
If diet and timing changes aren’t enough on their own, three categories of medication are available without a prescription. They work differently, and choosing the right one depends on how fast you need relief and how long your symptoms typically last.
- Antacids (Tums, Maalox, Mylanta, Rolaids) neutralize the acid already in your stomach. They work the fastest of the three options, often within minutes, but the relief is short-lived. These are your best bet for occasional, predictable flare-ups, like after a heavy meal.
- H2 blockers (famotidine, sold as Pepcid) reduce acid production by blocking one of the chemical signals that tells your stomach to make acid. They take about an hour to kick in, but relief lasts four to ten hours. If you know a trigger meal is coming, taking one beforehand can prevent symptoms.
- Proton pump inhibitors (omeprazole, lansoprazole) suppress acid production more powerfully than H2 blockers. They take one to four days to reach full effect, so they’re not useful for sudden symptoms. They’re designed for frequent indigestion that happens multiple days per week.
For most people, antacids are the right first step. If you find yourself reaching for them daily, stepping up to an H2 blocker makes more sense than just taking more antacids.
Why PPIs Aren’t a Forever Solution
Proton pump inhibitors are effective, but they were designed for short courses, typically two to eight weeks. Using them for months or years comes with real trade-offs. Because stomach acid plays a role in absorbing calcium and vitamin B12, long-term suppression has been linked to increased fracture risk and nutrient deficiencies. Stomach acid also kills harmful bacteria in food, so suppressing it raises your susceptibility to gut infections. Studies consistently show that people on long-term PPIs face roughly 1.5 to 2 times the risk of developing a serious intestinal infection called C. difficile compared to non-users.
None of this means you should never take a PPI. It means that if you’ve been on one for months and your symptoms are under control, it’s worth discussing with a provider whether you still need it or whether a lower level of treatment would maintain your relief.
Peppermint Oil Capsules
Enteric-coated peppermint oil capsules are a well-studied option that works for some people with indigestion and bloating. The enteric coating matters because it prevents the capsule from dissolving in your stomach (where peppermint can actually worsen heartburn) and instead delivers it to the intestines, where it relaxes the smooth muscle of the digestive tract. The typical dose is one capsule three times daily, taken 30 to 60 minutes before meals, with the option to increase to two capsules per dose if needed. Swallow them whole with water, since chewing or breaking them defeats the purpose of the coating.
When Indigestion Keeps Coming Back
Indigestion that recurs for weeks despite these measures may have an identifiable cause worth investigating. One common culprit is H. pylori, a bacterial infection that lives in the stomach lining. About 5% of chronic indigestion cases are directly attributable to this infection, and it’s easy to test for using a breath test or stool sample. If the test comes back positive, a short course of antibiotics can clear the infection and resolve symptoms that might otherwise persist indefinitely.
Ongoing indigestion can also be a sign that your stomach is overly sensitive to normal amounts of stretching or acid, a condition called functional dyspepsia. This is essentially a miscommunication between your gut and brain, where your digestive system sends discomfort signals in response to stimuli that wouldn’t bother most people. It’s not dangerous, but it can be stubborn to treat. Low-dose medications originally developed for mood disorders sometimes help by dialing down the sensitivity of the nerves in the gut wall.
Acupuncture as an Option
If conventional approaches haven’t given you enough relief, acupuncture has a reasonable evidence base for functional dyspepsia. A meta-analysis covering 24 trials and over 3,000 patients found that acupuncture improved both symptoms and quality of life. Most study protocols involved two to three sessions per week over four to six weeks. One well-designed trial showed that 12 sessions over four weeks produced significantly better outcomes than sham (placebo) acupuncture, which suggests the benefit isn’t just from the relaxation of lying still in a quiet room. It’s not a first-line treatment, but for people who’ve already tried medications and lifestyle changes without full relief, it’s a reasonable next step.
Symptoms That Need Prompt Attention
Most indigestion is uncomfortable but harmless. A few specific symptoms, however, signal something more serious: unintentional weight loss, difficulty swallowing or pain when swallowing, vomiting blood or material that looks like coffee grounds, and black or tarry stools. Indigestion that starts for the first time after age 50 or 55, with no obvious dietary explanation, also warrants a closer look. These don’t necessarily mean something dangerous is happening, but they do mean the cause needs to be identified rather than simply managed with antacids.
