Most stomach upset resolves on its own within a few hours, but you can speed things along with a combination of what you eat, what you drink, and a few simple techniques. The right approach depends on whether you’re dealing with nausea, acid reflux, cramping, or diarrhea, but several remedies work across the board.
Start With Small Sips, Not Food
If you’re actively nauseous or vomiting, skip solid food entirely and focus on fluids. Water, ice chips, weak tea, broth, and diluted fruit juice are all good starting points. Take small sips every few minutes rather than gulping, which can trigger more nausea. The goal is to replace lost fluids without overwhelming your stomach.
When vomiting or diarrhea is involved, plain water alone isn’t ideal because you’re also losing electrolytes. You can buy an electrolyte drink, or make a simple rehydration solution at home: mix 4 cups of water with half a teaspoon of table salt and 2 tablespoons of sugar. That ratio, based on oral rehydration guidelines, helps your intestines absorb fluid more efficiently than water alone.
Ginger Works, but Dose Matters
Ginger is one of the most studied natural remedies for nausea and stomach upset. Its active compounds block serotonin receptors in the gut (the same receptors targeted by prescription anti-nausea drugs), reduce inflammation, and help regulate how quickly your stomach moves food along. A systematic review in Food Science & Nutrition found that a total daily dose of around 1,000 to 1,500 mg, split into smaller portions, effectively reduced the severity of nausea and shortened recovery time.
In practical terms, that’s about a half-inch piece of fresh ginger root, grated into hot water as tea, or a 250 mg ginger capsule taken every six hours. Ginger chews and ginger ale (made with real ginger, not just flavoring) can also help, though the dose is harder to control. If you’re pregnant, 1 gram per day has been shown to be effective for morning sickness.
Peppermint for Cramping and Bloating
Peppermint works differently from ginger. It relaxes the smooth muscle lining your digestive tract by blocking calcium channels in those muscle cells, which reduces spasms and cramping. It also appears to dial down visceral sensitivity, meaning your gut literally sends fewer pain signals to your brain. Clinical trials support its use for functional dyspepsia (that heavy, bloated, uncomfortable feeling after eating) and irritable bowel symptoms.
Peppermint tea is the easiest option. For more targeted relief, enteric-coated peppermint oil capsules deliver the oil directly to the intestines rather than releasing it in the stomach, which can sometimes worsen heartburn. If acid reflux is your main issue, peppermint may not be your best choice since relaxing the muscle at the top of the stomach can let acid creep upward.
The Wrist Pressure Point Trick
There’s a pressure point on the inside of your wrist called P6 that can ease mild nausea. To find it, place three fingers flat across the inside of your opposite wrist, starting just below the crease where your hand meets your arm. The point sits in the groove between the two large tendons, right below where your third finger lands. Press firmly with your thumb for one to two minutes. It shouldn’t hurt.
You can also buy anti-nausea wristbands at most pharmacies that apply steady pressure to this spot. The effect is modest, but it’s free, has no side effects, and can be combined with any other remedy on this list.
Over-the-Counter Options
If home remedies aren’t cutting it, a few OTC products target different types of stomach distress. Choosing the right one matters.
Calcium carbonate antacids (like Tums) neutralize stomach acid directly and work within minutes. They’re best for heartburn or that burning, acidic feeling. The relief is fast but short-lived. H2 blockers (like famotidine) take about an hour to kick in but suppress acid production for 4 to 10 hours, making them better if you expect ongoing discomfort, like after a heavy meal.
Bismuth subsalicylate (the active ingredient in Pepto-Bismol) is more versatile. Once it hits your stomach, it breaks down into two components. One has antimicrobial properties that prevent bacteria from latching onto the stomach lining, reduce inflammation, and promote fluid absorption. The other reduces the production of compounds that cause intestinal cramping and hypermotility. It’s effective for nausea, diarrhea, and general upset. However, you should avoid it if you’re allergic to aspirin, take blood thinners, or have bleeding issues. It’s also not appropriate for children or teenagers with flu-like symptoms due to the risk of Reye’s syndrome.
What to Eat as You Recover
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a useful starting framework, but it’s no longer formally recommended as a strict protocol because those four foods lack protein, calcium, vitamin B12, and fiber. Following it for more than a day or two can actually slow your recovery by depriving your body of nutrients it needs to heal.
The broader principle still holds: eat bland, soft foods in small portions. Beyond the classic four, good options include brothy soups, oatmeal, boiled potatoes, saltine crackers, and dry cereal. As your stomach settles, add slightly more nutritious foods like scrambled eggs, skinless chicken or turkey, and cooked vegetables. Your stomach handles smaller, more frequent meals better than three large ones when it’s irritated. Let your appetite guide you, and don’t force yourself to eat before you’re ready.
Positioning Your Body Helps
How you sit and sleep affects how your stomach behaves. If acid reflux or a burning sensation is part of the problem, avoid lying flat. Propping your upper body at an angle, even just with an extra pillow, keeps gravity working in your favor.
If you need to lie down, choose your left side. The anatomy is straightforward: when you lie on your left, your esophagus sits above the level of your stomach, making it harder for acid and stomach contents to flow upward. A systematic review and meta-analysis confirmed that left-side sleeping significantly improved reflux symptoms. Lying on the right side does the opposite, positioning the stomach above the esophagus and promoting more reflux episodes and longer acid exposure.
Probiotics for Diarrhea-Related Upset
If your stomach trouble involves diarrhea, particularly from a stomach bug, certain probiotics can shorten the duration by roughly a day. The two strains with the strongest clinical evidence are Lactobacillus rhamnosus GG (sold as Culturelle) and Saccharomyces boulardii (sold as Florastor). Both have top-tier evidence ratings for treating infectious diarrhea. LGG reduces both the severity and duration of symptoms and is recommended by the American Academy of Pediatrics for children early in the course of acute diarrhea.
Probiotics won’t do much for nausea or heartburn, but if loose stools are your main complaint, starting a course early makes the biggest difference.
Red Flags That Need Attention
Most stomach upset from food, stress, or a mild virus resolves within a day or two. Vomiting from these causes is typically self-limited. But certain patterns signal something more serious. Severe pain that comes on suddenly, pain that wakes you from sleep, vomiting that won’t stop or contains blood, black or bloody stools, or a high fever alongside abdominal pain all warrant prompt medical evaluation. If your pain persists beyond 8 to 12 hours without improvement, or if new symptoms like fever or worsening pain develop after things initially seemed to be getting better, that’s also a reason to seek care rather than continuing to manage things at home.
