Acid indigestion improves with a combination of fast-acting remedies for immediate relief and simple habit changes that reduce how often it happens. Antacids work within minutes, certain foods and body positions make a real difference, and stronger medications are available when the burning keeps coming back. Here’s what actually works and how to use each option effectively.
Antacids for Immediate Relief
If you need the burning to stop right now, antacids are the fastest option. They work by directly binding to acid in your stomach, raising the pH within minutes of taking them. Liquid forms act faster than tablets, though both get the job done. The trade-off is that they don’t last long. The actual buffering effect wears off in about 30 minutes, and overall relief typically lasts around two hours.
Calcium-based antacids (like Tums) are among the most potent and fastest-acting. Magnesium- and aluminum-based options work similarly but may have different side effects with repeated use, like loose stools or constipation, respectively. For occasional flare-ups, any of these are fine. Just don’t rely on them daily for weeks on end, because that usually signals something worth addressing differently.
Baking Soda: A Pantry Fix With Limits
Sodium bicarbonate, or plain baking soda, neutralizes stomach acid quickly and costs almost nothing. A half teaspoon dissolved in a glass of cold water every two hours can ease heartburn in a pinch. The Mayo Clinic notes a daily maximum of about five teaspoons, and you shouldn’t use it for more than two weeks. Going beyond those limits raises the risk of throwing off your body’s acid-base balance, especially if you have kidney problems. It’s a reasonable short-term option, not an everyday habit.
Stronger Over-the-Counter Options
When antacids aren’t cutting it, two other types of medication reduce acid production rather than just neutralizing what’s already there.
H2 Blockers
Famotidine (Pepcid) is the most common one still on the market. It blocks one of the chemical signals that tells your stomach to make acid. The appeal is a quick onset, so you can take it as needed rather than committing to a daily schedule. The downside: your body can develop tolerance to the acid-suppressing effect within as few as three days of regular use. That tolerance sometimes persists even at higher doses. H2 blockers work best as an occasional tool, not a daily one.
Proton Pump Inhibitors
Omeprazole (Prilosec) and similar medications shut down the acid pumps in your stomach lining more completely. They’re the strongest option available without a prescription, but they’re not designed for quick relief. Because not all acid-producing cells are active at the same time, these medications need four to eight weeks of daily use to fully suppress acid output. Taking them “as needed” won’t reliably control symptoms.
Long-term use (months to years) has raised some concerns. A large meta-analysis found that people taking these medications had a modestly higher risk of fractures at the hip, spine, and other sites compared to nonusers, possibly because suppressing stomach acid interferes with calcium and vitamin B12 absorption. The absolute risk increase is small, though, and the overall quality of evidence linking these drugs to serious harm remains low after closer scrutiny. Still, most guidelines recommend using the lowest effective dose for the shortest time that controls your symptoms.
Foods and Drinks That Make It Worse
Some of the most common triggers relax the muscular valve between your esophagus and stomach, letting acid splash upward. Knowing which ones to cut back on can reduce how often indigestion strikes in the first place.
- Chocolate contains a compound called methylxanthine (chemically similar to caffeine) that relaxes that valve directly.
- Coffee does the same thing, and it doesn’t matter whether it’s caffeinated or decaf.
- Peppermint is often marketed as a digestive aid, but it also relaxes that valve and can worsen acid symptoms.
- Garlic and onions have a similar relaxing effect, especially when eaten raw.
- Fatty or fried foods slow stomach emptying, which means acid sits around longer.
You don’t necessarily need to eliminate all of these permanently. Most people find that one or two are their main triggers. Paying attention to which foods precede your worst episodes is more useful than following a rigid restriction list.
Eating Habits That Help
How you eat matters as much as what you eat. Large meals stretch the stomach and put more pressure on that lower valve. Eating smaller portions more frequently keeps your stomach from overfilling. Finishing your last meal or snack at least two to three hours before lying down gives your stomach time to empty, so there’s less acid available to travel upward when you’re horizontal.
Eating slowly also helps. Rushing through a meal leads to swallowing air, which increases stomach pressure and belching, both of which can push acid into the esophagus.
Sleep Position and Elevation
Gravity is one of the simplest tools against acid indigestion. When you lie flat, acid can pool at the junction between your stomach and esophagus. Elevating the head of your bed, or using a wedge pillow angled at 30 to 45 degrees (raising your head six to twelve inches), keeps acid where it belongs. This works better than stacking regular pillows, which tend to bend you at the waist and can actually increase abdominal pressure.
Sleeping on your left side also helps. Your stomach curves in a way that, when you’re on your left, the junction with your esophagus sits above the level of stomach acid. Rolling onto your right side or your back reverses that advantage.
Ginger
Ginger speeds up stomach emptying, which means food and acid move through faster rather than sitting and causing discomfort. It also reduces nausea by acting on receptors in the gut. The strongest clinical evidence supports doses of about 1,500 mg per day (split across meals) for nausea relief during pregnancy, but researchers haven’t pinned down a reliable dose for general indigestion. Studies have used anywhere from 400 mg to 3 grams daily with inconsistent results. Ginger tea or fresh ginger in cooking is unlikely to cause harm and may offer some relief, but don’t expect it to replace an antacid during a serious flare.
Chewing Gum After Meals
Chewing sugar-free gum for 30 minutes after eating can reduce acid indigestion symptoms. The mechanism is straightforward: chewing stimulates saliva production, and saliva naturally contains bicarbonate, which neutralizes acid. The increased swallowing that comes with chewing also helps clear any acid that has crept up into the esophagus. It’s not a powerful intervention, but it’s free, has no side effects, and can be a useful add-on after meals that tend to trigger symptoms.
Symptoms That Need Medical Attention
Occasional acid indigestion after a heavy meal is normal. Certain symptoms alongside indigestion, however, point to something more serious. These include difficulty swallowing, unintentional weight loss, vomiting blood or material that looks like coffee grounds, black or tarry stools, severe or constant abdominal pain, unexplained fatigue, and yellowing of the skin or eyes. Any of these warrants prompt evaluation, as they can signal ulcers, bleeding, or other conditions that home remedies won’t fix.
Indigestion that keeps returning more than twice a week for several weeks, or that doesn’t respond to the approaches above, also deserves a closer look. Persistent symptoms may indicate gastroesophageal reflux disease or another condition that benefits from a more targeted treatment plan.
