Indigestion usually responds well to a few simple steps you can take at home. Staying upright, avoiding food for a couple of hours, and reaching for an over-the-counter antacid will resolve most episodes within 15 to 30 minutes. If discomfort keeps coming back, the fix is often a combination of meal timing changes, trigger food awareness, and knowing which remedies actually work.
What to Do Right Now
If you’re in the middle of an episode, start by sitting up or standing. Gravity keeps stomach acid where it belongs. Lying down lets acid creep into your esophagus and makes everything worse. Loosen any tight clothing around your waist, since pressure on your stomach pushes its contents upward.
Take slow, deep breaths and avoid gulping water. Small sips of room-temperature water are fine, but drinking a large amount quickly can stretch your stomach further. A short, gentle walk can help move food through your digestive tract. Avoid bending over or doing anything that compresses your abdomen.
Over-the-Counter Options
Three categories of medication are available without a prescription, and they work differently depending on what you need.
Antacids (like Tums, Rolaids, or Mylanta) are the fastest option. They neutralize stomach acid that’s already there, so relief typically comes within minutes. They’re best for occasional, mild episodes. The downside is that the effect wears off relatively quickly.
H2 blockers (like Pepcid AC) reduce the amount of acid your stomach produces. They start working within one to three hours and provide relief for several hours afterward. These are a better choice if you know a meal is likely to cause trouble and want to get ahead of it, or if antacids aren’t lasting long enough.
Proton pump inhibitors (like Nexium 24HR or Prilosec OTC) are the strongest acid reducers, but they take one to four days to reach full effect. They’re not designed for immediate relief. These are meant for people who experience frequent heartburn over a stretch of time, not for a single bad episode after dinner.
The Baking Soda Option
Plain baking soda (sodium bicarbonate) works as a basic antacid in a pinch. The standard adult dose is half a teaspoon dissolved in a full glass of cold water. You can repeat this every two hours if needed, but don’t exceed five teaspoons in a single day.
There are some important limits. Don’t use baking soda for more than two weeks straight. Don’t take it within one to two hours of other oral medications, because it can interfere with absorption. And if you’re on a sodium-restricted diet, have high blood pressure, kidney disease, or heart disease, skip it entirely. Baking soda contains a significant amount of sodium and can cause your body to retain water.
Ginger and Other Home Remedies
Ginger has the strongest clinical support among herbal options. In a randomized trial, roughly 1,000 mg of ginger per day taken over four weeks improved common indigestion symptoms like feeling uncomfortably full after eating, early fullness during a meal, and upper abdominal pain. For a single episode, ginger tea made from fresh sliced ginger root is the simplest approach. Steep a thumb-sized piece in hot water for five to ten minutes.
Chamomile tea is a gentler option that many people find soothing, though its evidence base is thinner. One thing worth noting: peppermint, while commonly recommended, actually shows up on trigger food lists because it can relax the valve between your esophagus and stomach. If your indigestion involves acid reflux or a burning sensation in your chest, peppermint may make it worse rather than better.
Foods That Trigger Indigestion
The most common trigger foods share a pattern: they relax the muscular valve at the top of your stomach and slow digestion, letting food sit longer and giving acid more opportunity to cause problems. The biggest offenders are fried foods, fast food, fatty meats like bacon and sausage, cheese, pizza, and processed snacks like potato chips. Spicy seasonings, especially chili powder and black or cayenne pepper, are also frequent culprits.
Beyond the high-fat and spicy categories, a handful of other foods and drinks commonly cause trouble: tomato-based sauces, citrus fruits, chocolate, and carbonated beverages. You don’t necessarily need to cut all of these out permanently. Paying attention to which ones reliably cause your symptoms is more useful than following a generic restriction list. Most people have three or four personal triggers rather than all of them.
Meal Timing and Eating Habits
When and how you eat matters as much as what you eat. The single most impactful change for people with recurring indigestion is to stop eating at least three hours before lying down. The reason is straightforward: your stomach is a bag of food and acid, and gravity is the main force keeping that mixture from rising into your esophagus. When you lie down shortly after eating, that protection disappears.
Eating smaller meals more frequently, rather than two or three large ones, reduces the volume your stomach has to process at once. Chewing thoroughly and eating slowly gives your digestive system a head start on breaking food down. Rushing through meals or eating while stressed tends to cause you to swallow more air, which adds bloating and pressure on top of the acid issue.
Sleep Position Matters
If indigestion tends to bother you at night, your sleep position can make a real difference. A study of 57 people with chronic heartburn found that while sleeping position didn’t change how often acid entered the esophagus, acid cleared significantly faster when participants slept on their left side compared to their right side or back. The anatomy of your stomach makes this logical: when you’re on your left side, the junction between your esophagus and stomach sits above the level of stomach acid.
Elevating the head of your bed by about six inches, or using a wedge pillow, also helps. Stacking regular pillows isn’t as effective because it bends you at the waist rather than creating a gradual incline, and that bend can actually increase abdominal pressure.
Symptoms That Need Medical Attention
Most indigestion is uncomfortable but harmless. Certain symptoms, however, signal something more serious. Blood in your stool, difficulty swallowing, persistent nausea and vomiting, and unexplained weight loss are all red flags that warrant a doctor’s visit rather than another round of antacids. The same applies if your symptoms have persisted for more than two weeks despite over-the-counter treatment, or if they keep returning after you stop taking medication.
