Most indigestion clears up with a few simple changes to what, when, and how you eat, sometimes paired with an over-the-counter remedy for faster relief. The discomfort you’re feeling, whether it’s bloating, a burning sensation in your upper stomach, or that too-full feeling after a normal-sized meal, usually comes down to excess stomach acid, slow digestion, or both. Here’s how to tackle it.
Fast Relief With Over-the-Counter Options
If you need relief right now, antacids are the quickest option. They work by neutralizing stomach acid directly, and some formulas start working in under 10 minutes. A calcium-magnesium carbonate combination, for example, can raise stomach pH to a comfortable level in about 6 minutes. Plain calcium carbonate (the active ingredient in Tums) takes closer to 30 minutes but still works faster than other medication types. The tradeoff is that antacids wear off quickly, typically within 20 to 60 minutes on an empty stomach and somewhat longer after a meal.
If your indigestion tends to recur throughout the day, an H2 blocker like famotidine (Pepcid) lasts much longer, around 9 hours per dose, but takes about 60 to 90 minutes to kick in. That makes it better as a preventive step: take it before a meal you know will bother you rather than waiting for symptoms to start. Proton pump inhibitors (like omeprazole) are the strongest option and are designed for frequent heartburn, but they take days of regular use to reach full effect and aren’t meant for occasional discomfort.
A practical strategy for people who get indigestion often is to keep antacids on hand for immediate flare-ups and use an H2 blocker before meals that historically cause problems.
Foods That Commonly Trigger Symptoms
Certain foods relax the muscular valve between your stomach and esophagus, letting acid creep upward. The most reliable culprits are high-fat meals, chocolate, alcohol, and carbonated drinks. Fatty foods are a double hit: they relax the valve and slow down stomach emptying, which means food sits in your stomach longer and creates more pressure. That pressure pushes acid in the wrong direction.
Other common triggers include spicy foods, citrus fruits, tomatoes, onions, garlic, mint, and caffeinated drinks. You don’t necessarily need to eliminate all of these permanently. Pay attention to which ones consistently bother you, because triggers vary widely from person to person. Keeping a simple food log for a week or two can help you spot your specific patterns far more effectively than following a generic avoidance list.
Change How and When You Eat
Meal size matters as much as meal content. Large meals stretch the stomach and increase pressure on that valve, making reflux more likely. Eating smaller, more frequent meals gives your stomach less work to do at once. Eating slowly also helps, because it gives your brain time to register fullness before you’ve overeaten.
Timing is equally important. Wait at least two hours after eating before lying down. Your stomach needs that time to move food into the small intestine. If you eat dinner at 8 and go to bed at 8:30, you’re essentially asking gravity to work against your digestion. Shifting your last meal earlier in the evening is one of the simplest and most effective fixes for nighttime indigestion.
As for drinking water with meals, don’t worry about it. The old advice that water dilutes stomach acid and worsens digestion is a myth. Water actually helps break down food so your body can absorb nutrients more efficiently. Drink normally with your meals.
Elevate Your Head While Sleeping
If indigestion or heartburn bothers you at night, raising the head of your bed makes a measurable difference. In a well-designed clinical trial, people who elevated the head of their bed were roughly twice as likely to see meaningful symptom improvement at six weeks compared to those who slept flat. The elevation also reduced the amount of time acid spent in contact with the esophagus.
The key detail is how you elevate. Propping yourself up with extra pillows tends to bend you at the waist, which can actually increase abdominal pressure. Instead, place 6- to 8-inch blocks (about 20 cm) under the legs at the head of your bed, or use a wedge-shaped pillow designed to create a gradual incline from your hips to your head. Both approaches work; the goal is a gentle slope, not a sharp angle.
Ginger as a Natural Remedy
Ginger has genuine clinical support for indigestion. It speeds up the rate at which your stomach empties and stimulates the muscle contractions that push food through your digestive tract. In trials on people with chronic indigestion, ginger extract taken before meals significantly reduced symptoms including nausea, bloating, fullness, and upper stomach pain compared to placebo.
The doses used in studies typically correspond to about 2 grams of fresh ginger root (roughly a one-inch piece), taken twice daily. You can grate it into hot water for tea, use ginger capsules, or add it to food. Ginger chews and candies made with real ginger can also help in a pinch, though many commercial products contain minimal actual ginger, so check the label.
Baking Soda: Quick but Limited
Dissolving baking soda (sodium bicarbonate) in water is one of the oldest home remedies for indigestion, and it does work. It neutralizes acid almost instantly, with measurable pH changes in as little as 6 seconds. The typical dose is half a teaspoon to two and a half teaspoons dissolved in a glass of cold water after meals, with a maximum of five teaspoons per day.
The catch is that baking soda is high in sodium, which causes the body to retain water. That makes it a poor choice if you have high blood pressure, heart disease, kidney disease, or swelling in your legs and feet. It can also worsen intestinal bleeding. For occasional use in otherwise healthy people, it’s fine. For frequent indigestion, a commercial antacid or an H2 blocker is safer and more practical long-term.
When Indigestion Signals Something More
Occasional indigestion after a big meal or a stressful day is normal. But if symptoms like upper stomach pain, burning, bloating, or feeling full after just a few bites persist for three months or longer, it may be functional dyspepsia, a condition where the stomach is chronically irritated even without a visible cause like an ulcer. This is common and treatable, but it usually requires a different approach than occasional heartburn.
Certain symptoms should prompt a call to your doctor sooner rather than later. These include unintentional weight loss, difficulty swallowing, painful swallowing, persistent vomiting, and unexplained anemia (which can show up as unusual fatigue or pallor). A family history of stomach or esophageal cancer also lowers the threshold for getting checked. For people 60 and older, gastroenterology guidelines recommend evaluation for new or worsening indigestion even without these warning signs, since the risk of underlying conditions increases with age.
