Most indigestion passes within a few hours, but when you’re dealing with that uncomfortable fullness, bloating, or burning right now, a few simple strategies can speed things along. The fastest option in your medicine cabinet is a standard antacid, which starts working within five minutes. If you don’t have one on hand, your kitchen and a few habit changes can still bring meaningful relief.
Baking Soda: The Fastest Kitchen Fix
Sodium bicarbonate, the same baking soda sitting in your pantry, neutralizes stomach acid almost immediately on contact. Dissolve half a teaspoon in a four-ounce glass of water and drink it. The relief is real but short-lived, typically lasting 30 minutes to two hours. This works best as a one-time rescue, not a daily habit. Baking soda is high in sodium, so avoid it if you’re watching your salt intake or have high blood pressure, and don’t exceed five half-teaspoon doses in a 24-hour period.
Ginger for Nausea and Bloating
Ginger has a long track record for settling the stomach. Compounds in ginger root enhance movement through the digestive tract, which helps when indigestion feels like food is just sitting there. It also has anti-nausea effects that work both in the gut and the brain. The simplest approach is ginger tea: slice a thumb-sized piece of fresh ginger, steep it in hot water for five to ten minutes, and sip slowly. Ginger chews or capsules from a pharmacy work too. Most people notice some improvement within 20 to 30 minutes.
Change Your Position
Gravity is surprisingly effective medicine for indigestion. If you’ve just eaten a big meal, resist the urge to lie down. Sitting upright or taking a gentle walk keeps stomach contents where they belong and encourages your digestive system to keep moving.
If you do need to lie down, choose your left side. In that position, your esophagus and the muscular ring that seals it sit higher than your stomach, so acid drains away from the esophagus more quickly. Lying on your right side or flat on your back does the opposite, letting acid pool near that opening and making the burning worse. Propping your head and upper body with an extra pillow or two adds another layer of help.
Chew Gum After Eating
This one sounds too easy, but chewing sugar-free gum for 20 to 30 minutes after a meal can genuinely reduce acid-related discomfort. Chewing stimulates your salivary glands, and saliva naturally contains bicarbonate, a mild acid neutralizer. The extra swallowing also pushes any acid that has crept into your esophagus back down into the stomach. Bicarbonate gum, if you can find it, amplifies the effect. Avoid mint-flavored varieties if mint tends to trigger your symptoms, since it can relax the valve between your stomach and esophagus.
Over-the-Counter Options at Home
If you keep a medicine cabinet stocked for occasional stomach trouble, you likely already have what you need. Chewable antacids containing calcium carbonate start providing relief within about five minutes by directly neutralizing acid in the stomach. They’re the fastest acting option, though the effect wears off in one to three hours.
H2 blockers like famotidine take longer to kick in, roughly an hour, but they work differently. Instead of neutralizing acid that’s already there, they reduce how much acid your stomach produces in the first place. The tradeoff in speed pays off in duration: relief from an H2 blocker typically lasts 6 to 12 hours. If your indigestion tends to linger or return through the evening, an H2 blocker is the better choice. For immediate discomfort that you want gone right now, start with an antacid and consider adding an H2 blocker if the problem keeps coming back.
What Won’t Help: Apple Cider Vinegar
Apple cider vinegar is one of the most commonly recommended home remedies for indigestion online, but there is no published clinical research supporting its use for heartburn or acid reflux. The popular theory is that adding acid to the stomach somehow tightens the valve at the top, but researchers at Harvard Health have pointed out that the mechanism controlling that valve involves a complex network of involuntary muscles, hormones, and neurotransmitters, not just acidity levels. Drinking vinegar when your stomach is already irritated can make things worse, especially if the lining is inflamed. Skip this one.
Quick Habits That Prevent the Next Episode
Once you’ve calmed the current bout, a few small changes make the next one less likely:
- Eat smaller portions. A stretched stomach puts pressure on the valve that keeps acid contained. Splitting a large meal into two smaller ones is often enough to prevent symptoms entirely.
- Slow down at meals. Eating quickly means swallowing more air, which adds to bloating and pressure. Chewing thoroughly also gives your stomach a head start on digestion.
- Avoid lying down for two to three hours after eating. This is the single most effective lifestyle change for people who get indigestion in the evening.
- Loosen tight clothing. Anything that compresses your abdomen, belts, waistbands, shapewear, increases pressure on the stomach and can push acid upward.
- Identify your triggers. Common culprits include fatty or fried foods, carbonated drinks, caffeine, alcohol, chocolate, tomato-based sauces, and raw onions. You don’t necessarily need to avoid all of these, just the ones that consistently cause you trouble.
Signs That Something More Serious Is Happening
Indigestion and a heart attack can feel uncomfortably similar. Standard heartburn causes a burning sensation in the chest, usually after eating, and it typically improves with antacids. A cardiac event is more likely to involve pressure, tightness, or a squeezing sensation in the chest or arms that spreads to the neck, jaw, or back. It often comes with shortness of breath, cold sweats, lightheadedness, or sudden fatigue. Women are more likely than men to experience jaw pain, back pain, and nausea as primary symptoms rather than classic chest pressure.
If your discomfort doesn’t match the usual pattern of your indigestion, if it came on during exertion rather than after a meal, or if you notice any of those additional symptoms, treat it as an emergency. Outside of cardiac concerns, indigestion that persists for more than two weeks, comes with unintentional weight loss, difficulty swallowing, or persistent vomiting warrants a visit to your doctor. For adults over 55 with new or changing digestive symptoms, guidelines recommend blood work to rule out underlying conditions.
