Indigestion usually goes away on its own, but you can speed things along with a few simple changes to how and when you eat, along with some targeted home remedies. Most episodes come down to eating too fast, eating too much, or eating something that doesn’t agree with your stomach. The fix depends on whether you’re dealing with a one-time flare or a recurring problem.
What’s Actually Happening in Your Stomach
Indigestion (the medical term is dyspepsia) is a gnawing or aching pain in the upper abdomen that sometimes improves after eating and sometimes gets worse. It can show up with bloating, nausea, or a feeling of uncomfortable fullness after just a few bites. About 40% of chronic cases are “functional dyspepsia,” meaning there’s no visible damage or disease causing the symptoms. The stomach simply isn’t processing food efficiently.
This is different from heartburn, which is a burning sensation behind the breastbone caused by stomach acid washing back up into the esophagus. The two overlap so often that even doctors find them hard to tell apart, and you can absolutely have both at the same time. But the distinction matters because some remedies that help one can worsen the other.
Quick Relief at Home
If indigestion has already hit, a few options can calm things down within minutes to hours.
Baking soda in water. Half a teaspoon of sodium bicarbonate dissolved in a full glass of water neutralizes stomach acid fast. Take it one to two hours after a meal, not on a completely full stomach. Don’t rely on this for more than two weeks at a stretch, and skip it entirely if you have high blood pressure, heart failure, kidney disease, or you’re on a sodium-restricted diet. It’s also not appropriate for children under 12.
Ginger. Fresh ginger or ginger supplements help the stomach move food through more quickly, which addresses that heavy, overly full feeling. Clinical trials have used doses ranging from 170 mg to 1 g taken three to four times daily. A simple approach: steep a few thin slices of fresh ginger in hot water for five to ten minutes and sip it slowly.
Peppermint oil capsules. Peppermint relaxes the muscles of the digestive tract, which can ease cramping and bloating. Look for enteric-coated capsules specifically. The coating prevents the oil from dissolving in the stomach, where it could actually relax the valve between your esophagus and stomach and make heartburn worse. The American College of Gastroenterology has endorsed peppermint oil for digestive symptom relief, noting that enteric-coated versions help avoid that reflux side effect.
A short walk. Gentle movement after eating helps your digestive system do its job. Even 10 to 15 minutes of walking can reduce bloating and that sluggish, overstuffed feeling. Avoid intense exercise, which can have the opposite effect.
Foods and Drinks That Make It Worse
Certain foods are reliable indigestion triggers for most people. Fatty and fried foods sit in the stomach longer than other foods, which increases the chance that acid splashes back up into the esophagus. Spicy foods, citrus, tomato sauces, and vinegar can intensify the burning. Chocolate, caffeine, onions, peppermint (in food or tea form, as opposed to enteric-coated capsules), carbonated drinks, and alcohol all tend to worsen symptoms too.
You don’t necessarily need to eliminate all of these permanently. Pay attention to which ones consistently bother you. For many people, the problem isn’t a specific food but the quantity. A small portion of something rich might be fine; a large one isn’t.
How You Eat Matters as Much as What You Eat
Eating too quickly is one of the most common and most overlooked causes of indigestion. When you rush through a meal, you swallow more air and your stomach receives large amounts of food before it’s had time to ramp up its digestive process. Smaller, more frequent meals tend to cause fewer problems than two or three large ones.
Chewing thoroughly sounds like obvious advice, but it makes a genuine difference. Digestion starts in the mouth, and the more mechanical breakdown that happens before food reaches the stomach, the less work the stomach has to do.
Nighttime Indigestion and Sleep Position
If your indigestion tends to flare up at night, two changes can make a significant difference. First, stop eating at least three hours before bed. When you lie down with a full stomach, gravity can no longer keep food and acid where they belong. Your stomach is essentially a bag of food and acid, and going horizontal lets the contents drift toward the esophagus.
Second, if you do get symptoms at night, try sleeping on your left side. In this position, the esophagus and the muscular ring that separates it from the stomach sit higher than the stomach itself. Acid drains away from the esophagus more quickly than in any other sleeping position. Propping the head of your bed up by about six inches (using blocks under the bed frame, not just extra pillows) provides additional gravity assistance.
Over-the-Counter Options
Standard antacids (the chewable tablets you find at any pharmacy) work by neutralizing stomach acid and typically bring relief within minutes. They’re fine for occasional use but wear off relatively quickly, usually within one to three hours.
If you’re reaching for antacids more than a couple of times a week, acid-reducing medications that work for a longer window may be more effective. These come in two main categories: one type reduces the amount of acid your stomach produces over several hours, while a stronger type shuts down acid production more completely for up to 24 hours. Both are available without a prescription, but the stronger type is designed for short courses of two weeks, not indefinite daily use.
When Indigestion Signals Something Else
Occasional indigestion after a big meal is normal. Persistent or worsening symptoms deserve a closer look. Pay attention to a few specific warning signs: unintended weight loss alongside your digestive symptoms, difficulty swallowing, vomiting (especially if there’s blood), or black, tarry stools. These can indicate something beyond garden-variety indigestion.
If you feel like food is physically stuck in your throat or chest, that warrants an emergency room visit. The same is true if a blockage makes it hard to breathe. And if you’ve had indigestion most days for two weeks or more despite trying the approaches above, it’s worth getting evaluated. Conditions like stomach ulcers, infections (particularly a common bacterial infection that’s easily treated with a course of antibiotics), and gallbladder problems can all masquerade as simple indigestion.
