Most upset stomachs resolve on their own within a day or two, but the right combination of simple remedies can ease nausea, cramping, and bloating much faster. What works best depends on your specific symptoms, whether that’s queasiness, diarrhea, sharp cramps, or general discomfort after eating. Here’s what actually helps.
Ginger for Nausea
Ginger is one of the most reliable natural options for settling nausea. Its active compounds speed up the rate at which your stomach empties, which reduces that heavy, queasy feeling. It also acts directly on receptors in your digestive tract that trigger the urge to vomit.
The effective dose is about 1 gram per day, typically split into smaller amounts throughout the day. That’s roughly a half-inch piece of fresh ginger root steeped in hot water for tea, or a couple of ginger capsules. Ginger chews, ginger ale made with real ginger, and crystallized ginger all work too, though the concentration varies. Standardized ginger capsules give you the most consistent dose. If you’re pregnant, the studied dosage is 250 mg four times daily, not exceeding 1 gram total.
Stay Hydrated (But Do It Right)
When your stomach is upset, especially if vomiting or diarrhea is involved, dehydration becomes the bigger threat. Plain water helps, but your body absorbs fluid much more efficiently when it contains a small amount of sugar and salt together. The sugar activates a transport mechanism in your intestinal lining that pulls sodium and water along with it.
You can make a simple rehydration drink at home: 4 cups of water, half a teaspoon of table salt, and 2 tablespoons of sugar. Sip it slowly rather than gulping. If that sounds unappealing, diluted sports drinks or coconut water are reasonable alternatives, though they aren’t perfectly balanced. The key is small, frequent sips. Drinking too much too fast when your stomach is already irritated often triggers more vomiting.
What to Eat (and What to Skip)
The old advice to eat only bananas, rice, applesauce, and toast (the BRAT diet) isn’t wrong, but it’s more restrictive than necessary. Those four foods are fine for the first day or two, but there’s no clinical evidence that limiting yourself to just those items leads to faster recovery. A broader range of bland, easy-to-digest foods works just as well and provides more of the nutrients your body needs to bounce back.
Good options include brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereals. Once your stomach starts to settle, you can add cooked carrots, butternut squash, avocado, skinless chicken or turkey, fish, and eggs. All of these are gentle on the digestive tract while supplying protein and vitamins that pure starches lack. Avoid greasy, spicy, or highly acidic foods until you feel fully recovered. Dairy can also be harder to digest when your gut is inflamed, so hold off on milk and cheese for a day or two.
Peppermint for Cramping and Bloating
If your upset stomach involves cramping, bloating, or a feeling of pressure, peppermint oil can help. It relaxes the smooth muscle in your digestive tract, which reduces spasms and lets trapped gas move through more easily. A 2022 review of 10 studies with over 1,000 participants found that peppermint oil significantly improved abdominal pain compared to placebo.
Enteric-coated peppermint oil capsules are the most effective form because the coating prevents the oil from dissolving in your stomach (where it can cause heartburn) and delivers it to your intestines instead. Peppermint tea is a milder option that still provides some relief. If your upset stomach is primarily acid reflux or heartburn, skip peppermint entirely. It relaxes the valve between your esophagus and stomach, which can make reflux worse.
Over-the-Counter Medications
Pink bismuth liquid or tablets (the active ingredient in Pepto-Bismol and similar products) work through several mechanisms at once. They reduce inflammation inside your intestines, slow the flow of excess fluid into your bowel, and have mild antimicrobial effects that can help with traveler’s diarrhea and food poisoning. This makes bismuth particularly useful when your upset stomach includes diarrhea alongside nausea.
Antacids are a better choice if your discomfort is centered in your upper stomach and feels like burning or acidic pressure. They neutralize stomach acid quickly, though the relief is temporary. Simethicone (sold as Gas-X) specifically targets bloating by breaking up gas bubbles in your digestive tract but won’t help with nausea or diarrhea.
Heat on Your Belly
A heating pad or hot water bottle placed on your abdomen is a surprisingly effective tool. The warmth increases blood flow to your digestive organs and stimulates your parasympathetic nervous system, which is the branch responsible for “rest and digest” functions. This boosts digestive motility, relaxes sphincter muscles, and increases secretions that help move things along. If your upset stomach involves constipation or dull, aching cramps, heat often provides more noticeable relief than medication. Keep the temperature comfortable (not scalding) and apply for 15 to 20 minutes at a time.
Probiotics for Stomach Bugs
If your upset stomach is caused by a stomach virus or food poisoning, a specific type of probiotic yeast called Saccharomyces boulardii can shorten the duration of symptoms. In a controlled trial, people taking this probiotic recovered in about 3 days compared to nearly 5 days in the group that didn’t take it. By day 3, 76% of the probiotic group had returned to normal stool consistency, compared to just 24% in the control group.
S. boulardii is available over the counter under brand names like Florastor. It works best when started early and taken alongside adequate fluids. Regular bacterial probiotics (like those containing Lactobacillus) have weaker evidence for acute stomach bugs, though they may help restore your gut balance afterward.
Red Flags That Need Attention
Most upset stomachs are harmless and temporary. But certain symptoms signal something more serious. Seek medical care if you notice blood in your vomit or stool, vomit that’s green or yellow (bilious), a fever of 38.5°C (101.3°F) or higher, severe abdominal pain with a rigid or distended belly, or unusual lethargy where you feel far more exhausted than the situation seems to warrant. Persistent vomiting that prevents you from keeping any fluids down for more than 24 hours also warrants a call, because dehydration from that level of fluid loss can become dangerous on its own.
