The best remedy for indigestion depends on how fast you need relief and how often it happens. For occasional discomfort after a meal, an over-the-counter antacid works within minutes. For recurring symptoms, lifestyle changes and longer-acting medications are more effective strategies.
How the Three Types of OTC Medications Compare
Over-the-counter options for indigestion fall into three categories, and each works on a different timeline. Antacids (like calcium carbonate or magnesium hydroxide) act the fastest, neutralizing stomach acid almost immediately. The tradeoff is that their effects wear off quickly, often within an hour or two. They’re best suited for occasional, short-lived discomfort.
H2 blockers take about an hour to kick in but provide relief for four to ten hours. They work by reducing the amount of acid your stomach produces rather than just neutralizing what’s already there. This makes them a better choice if you know a meal is likely to bother you and want to get ahead of it.
Proton pump inhibitors (PPIs) are the most powerful option but the slowest to start working. It can take one to four days to feel their full effect. Their relief lasts much longer than either antacids or H2 blockers, which is why they’re typically recommended for frequent symptoms rather than one-off episodes. If you find yourself reaching for antacids more than twice a week, a PPI may be worth trying for a short course.
Foods and Drinks That Commonly Trigger Symptoms
Certain foods are well-established indigestion triggers. The most common culprits include fatty or greasy foods, carbonated drinks, caffeine (in coffee, tea, and sodas), fruits and fruit juices, and grain or wheat products. Fatty foods are particularly problematic because they slow down stomach emptying, leaving food sitting in your stomach longer and increasing the chance of discomfort, bloating, and nausea.
You don’t necessarily need to eliminate all of these permanently. Pay attention to which specific foods consistently cause problems for you. Eating smaller portions, chewing thoroughly, and avoiding eating within two to three hours of lying down can make a significant difference even without cutting anything from your diet entirely.
Home Remedies That Actually Help
Baking soda is one of the oldest and cheapest home remedies for indigestion, and it does work. It’s essentially a basic antacid. The Mayo Clinic lists a standard dose of half a teaspoon dissolved in a glass of water, taken every two hours as needed. Keep a few things in mind, though: don’t use it for more than two weeks straight, don’t take it within one to two hours of other medications (it can interfere with absorption), and avoid combining it with large amounts of milk. Because baking soda is high in sodium, people with high blood pressure, kidney disease, heart disease, or swelling in the legs should avoid it.
Ginger has a long history of use for stomach discomfort and is backed by evidence showing it speeds up stomach emptying and reduces upper digestive symptoms. Fresh ginger tea, ginger chews, or ginger supplements are all reasonable options. Peppermint tea is another popular choice, though the evidence for it specifically treating indigestion is thinner. Some people find it soothing, while others notice it worsens heartburn because it relaxes the valve between the stomach and esophagus.
Sleep Position Matters More Than You’d Think
If indigestion tends to bother you at night, how you sleep can make a real difference. A study published through Harvard Health monitored 57 people with chronic heartburn and found that while sleeping position didn’t change how often acid refluxed into the esophagus, acid cleared much faster when participants slept on their left side compared to their right side or back. Combining left-side sleeping with a wedge pillow to elevate your upper body gives you the best shot at a comfortable night.
When Indigestion Keeps Coming Back
Indigestion that recurs for weeks or months sometimes has a treatable underlying cause. One of the most common is infection with a stomach bacterium called H. pylori, which is present in a significant portion of people with chronic digestive symptoms. Current clinical guidelines recommend testing for this bacterium in anyone with persistent indigestion. Treatment involves a course of antibiotics, and while not everyone feels better afterward, those who do test positive and get treated often see lasting improvement.
Persistent indigestion without an obvious cause is classified as functional dyspepsia, meaning the digestive system isn’t working quite right even though nothing looks structurally wrong. For this type, a combination of dietary adjustments, stress management, and sometimes a short course of a PPI or other medication tends to be the most effective approach.
Chest Pain That Might Not Be Indigestion
Indigestion and heart attacks can feel surprisingly similar. Heart attack symptoms often include nausea, abdominal pain, and a sensation that many people initially describe as heartburn. The key distinguishing features of a heart attack are pressure or tightness in the chest that spreads to your arms, neck, jaw, or back, along with shortness of breath, cold sweats, lightheadedness, or sudden fatigue. Women are more likely than men to experience the less obvious symptoms like jaw pain, back pain, and nausea without the classic crushing chest pressure.
Both heartburn and heart attacks can produce symptoms that come and go, so the pain doesn’t have to be constant or long-lasting to be serious. If you have persistent chest pain and aren’t sure it’s just indigestion, call 911. If you had an episode of unexplained chest pain that resolved on its own and you didn’t seek medical attention at the time, follow up with your doctor.
