For a basic upset stomach, ginger, antacids, and bland foods are the fastest and most accessible options. What works best depends on your specific symptoms: nausea, heartburn, bloating, or diarrhea each respond to different remedies. Here’s a breakdown of what actually helps and when to reach for each option.
For Nausea: Ginger and Peppermint
Ginger is one of the most reliable natural remedies for nausea. It works well enough that the National Center for Complementary and Integrative Health recognizes it as helpful for morning sickness during pregnancy. You can take it as tea, chew on crystallized ginger, or use ginger capsules. Fresh ginger steeped in hot water for 5 to 10 minutes makes a simple, effective tea.
Peppermint is another strong option. A 2021 review found that simply inhaling peppermint oil helps prevent nausea and vomiting, which makes it useful when you can’t keep anything down. Peppermint tea works too, though the concentration is lower than peppermint oil capsules. One caution: peppermint can make heartburn worse by relaxing the valve between your stomach and esophagus, so skip it if acid reflux is part of your problem.
For Heartburn and Acid: Antacids and Acid Reducers
If your stomach feels burning or sour, the issue is likely excess acid. Calcium carbonate antacids (the chewable tablets you’ll find in any pharmacy) neutralize stomach acid on contact and provide relief within minutes. They’re best for occasional, short-term use.
For heartburn that keeps coming back or lasts more than a few hours, an acid reducer like famotidine works differently. Instead of neutralizing acid that’s already there, it reduces how much acid your stomach produces. The standard over-the-counter dose is 20 mg, and it typically lasts 8 to 12 hours. Famotidine takes longer to kick in (usually 30 to 60 minutes) but provides more sustained relief than a chewable antacid.
Proton pump inhibitors are the strongest OTC acid reducers available. They’re designed for frequent heartburn (two or more days per week) and take one to four days to reach full effect, so they’re not the right choice when you need fast relief right now.
For Bloating and Gas
Simethicone is the go-to for trapped gas and bloating. It works by merging small gas bubbles in your gut into larger ones, making it easier for your body to pass them. It doesn’t get absorbed into your bloodstream, which means side effects are rare. You can take it after meals or whenever bloating hits. People with IBS sometimes use it regularly to manage gas-related discomfort.
Peppermint oil capsules also help with bloating. A 2022 meta-analysis found peppermint oil more effective than a placebo at reducing IBS symptoms, including bloating, gas, and constipation. The key is using enteric-coated capsules so the oil releases in your intestines rather than your stomach.
For Diarrhea and General Stomach Bugs
Bismuth subsalicylate (the active ingredient in pink stomach relief liquids and tablets) coats your stomach lining and reduces inflammation in your gut. It helps with diarrhea, nausea, and that general “something is off” feeling. One important safety note: it contains a compound related to aspirin, so the FDA requires a warning that children and teenagers recovering from chicken pox or flu-like symptoms should not use it, due to the risk of Reye’s syndrome, a rare but serious condition.
Probiotics can also shorten a bout of diarrhea. The yeast-based probiotic Saccharomyces boulardii has the strongest evidence. In a meta-analysis of six randomized controlled trials, people taking it recovered about 1.6 days faster than those who didn’t, and significantly more were fully cured by the end of each study. It also reduced two key markers of gut inflammation. You can find it in capsule form at most pharmacies, and it’s generally well tolerated.
Bland Foods That Help Recovery
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a reasonable starting point for the first day or two of a stomach bug, food poisoning, or traveler’s diarrhea, but there’s no clinical evidence that it works better than other bland foods. According to Harvard Health, there’s no need to restrict yourself to just those four items.
Brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereals are equally easy to digest. Once your stomach starts settling, adding more nutritious foods helps you recover faster. Cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs are all bland enough to be gentle on your stomach while providing the protein and nutrients your body needs to bounce back. The main things to avoid while your stomach is upset: fatty or fried foods, dairy, caffeine, alcohol, and heavily spiced dishes.
Choosing the Right Remedy by Symptom
- Nausea without heartburn: ginger tea, peppermint tea, or peppermint oil
- Burning or sour stomach: calcium carbonate antacid for quick relief, famotidine for longer-lasting relief
- Bloating and trapped gas: simethicone or enteric-coated peppermint oil capsules
- Diarrhea: bismuth subsalicylate or Saccharomyces boulardii probiotics
- General queasiness from a stomach bug: small sips of ginger tea, bland foods, and bismuth subsalicylate
Symptoms That Need Medical Attention
Most stomach upset resolves on its own within a day or two. But certain symptoms signal something more serious. The American College of Emergency Physicians recommends seeking emergency care if your abdominal pain is sudden, severe, or doesn’t ease within 30 minutes. Continuous severe pain with persistent vomiting can indicate a life-threatening condition.
Other red flags include fever with abdominal pain, blood in your vomit or stool, severe pain concentrated in your lower right abdomen (a classic sign of appendicitis), and pain in the middle upper abdomen that worsens after eating (which can indicate pancreatitis). If you’re unable to keep any fluids down for more than 12 hours, dehydration becomes a concern on its own, especially in young children and older adults.
