Most stomach upset responds well to a combination of simple home remedies, gentle foods, and rest. Whether you’re dealing with nausea, bloating, cramping, or general queasiness, the goal is the same: reduce irritation, relax the muscles lining your digestive tract, and give your gut time to settle. Here’s what actually works and why.
Ginger for Nausea and Cramping
Ginger is one of the most reliable natural options for an upset stomach, particularly when nausea is the main symptom. Its active compounds influence how your stomach muscles contract, helping to move things along without the spasms that cause that churning feeling. Clinical trials have used doses ranging from 250 mg to 1 g per day, split into three or four smaller portions throughout the day. Higher doses (around 2 g) don’t appear to work any better than 1 g, so more isn’t necessarily more helpful here.
You don’t need capsules. A thumb-sized piece of fresh ginger steeped in hot water for five to ten minutes makes a simple tea. Ginger chews and crystallized ginger also work. If you’re dealing with motion sickness or post-meal queasiness, try sipping ginger tea slowly rather than drinking it all at once.
Peppermint Relaxes Gut Muscles
Peppermint works differently from ginger. The menthol in peppermint directly relaxes the smooth muscle lining your intestines by blocking calcium channels that trigger those muscles to contract. This is why peppermint tea can ease bloating, gas pain, and that tight, crampy feeling in your abdomen. The effect is dose-dependent: more menthol means more relaxation of gut contractions, without affecting the natural rhythm of your digestive system.
Peppermint tea is the simplest option. If bloating or intestinal cramps are your primary issue, enteric-coated peppermint oil capsules deliver the menthol further down the digestive tract where it’s needed most. One caution: if your stomach trouble is acid reflux or heartburn, peppermint can make it worse by relaxing the valve between your esophagus and stomach. In that case, skip it.
Chamomile Tea for Stress-Related Upset
If your stomach acts up when you’re stressed or anxious, chamomile is a better pick than peppermint. Chamomile has anti-inflammatory properties that can soothe irritated tissue in your digestive tract, and it also reduces the stress and anxiety that often trigger stomach symptoms in the first place. High stress levels correlate directly with increased acid reflux and gut irritability, so calming your nervous system calms your stomach.
Drink it after meals or before bed. Chamomile can cause mild drowsiness, which is actually a benefit if nighttime stomach discomfort is keeping you up.
Use Deep Breathing to Activate Your Gut’s “Off Switch”
This one sounds too simple, but the physiology behind it is solid. Breathing deeply with your diaphragm (the muscle under your ribs, not shallow chest breathing) activates your vagus nerve. This nerve is the main line of communication between your brain and your gut, and stimulating it triggers your body’s relaxation response while dialing down its stress response. That shift from “fight or flight” to “rest and digest” directly reduces stomach churning, nausea, and cramping.
Try this: place one hand on your chest and one on your belly. Breathe in slowly through your nose for four counts, letting your belly push out while your chest stays mostly still. Exhale through your mouth for six counts. Repeat for two to three minutes. This works especially well alongside other remedies, since a calmer nervous system makes everything else more effective.
Apply Heat to Your Abdomen
A heating pad or hot water bottle on your stomach isn’t just comforting. When heat above 40°C (104°F) reaches your skin, it activates heat receptors that block pain receptors in the underlying tissue. Researchers at University College London found that these heat receptors (called TRPV1) directly shut down the chemical signals that damaged or irritated cells send to register pain. This is why a warm compress can take the edge off cramping, bloating, and that deep visceral ache that’s hard to pinpoint.
Place a heating pad or warm water bottle wrapped in a thin towel over your stomach for 15 to 20 minutes. This pairs well with deep breathing or lying on your left side, which keeps your stomach positioned below your esophagus and can reduce acid-related discomfort.
What to Eat (and What to Avoid)
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It still has a role as a short-term strategy, especially if you’re dealing with diarrhea, because these low-fiber, easy-to-digest foods give your gut less work to do. But nutritional guidelines have shifted away from strict BRAT-only eating. The current recommendation is to start reintroducing other bland, low-fat foods as soon as you can tolerate them: plain crackers, boiled potatoes, clear broth, steamed chicken, or oatmeal.
While your stomach is upset, avoid the things that make it work harder or produce more acid: fried or greasy foods, dairy (if it bothers you), caffeine, alcohol, spicy foods, and carbonated drinks. Eat smaller portions more frequently rather than full meals. This keeps your stomach from stretching too much, which can trigger more nausea and cramping.
Stay hydrated, especially if you’ve been vomiting or have diarrhea. Small sips of water, diluted broth, or an electrolyte drink are better than gulping large amounts at once, which can make nausea worse.
Probiotics for Recurring Stomach Trouble
Probiotics are less about calming your stomach in the moment and more about reducing how often it gets upset. A large meta-analysis published in The Lancet’s eClinicalMedicine found that specific probiotic strains can meaningfully reduce abdominal pain and other gut symptoms, but the key word is “specific.” Not all probiotics do the same thing. Out of 14 different probiotic types analyzed, nine showed significant benefit for at least one digestive outcome, while four showed no benefit at all.
If you have ongoing issues like frequent bloating, cramping, or irregular digestion, look for products that list their strains on the label. Lactobacillus rhamnosus GG is one of the most studied strains for gut health, with multiple trials showing improvements in abdominal pain compared to placebo. Saccharomyces boulardii is another well-supported option, particularly for diarrhea-related symptoms. Give any probiotic at least two to four weeks before judging whether it’s helping.
Over-the-Counter Options
When home remedies aren’t enough, the right OTC medication depends on your specific symptoms. For heartburn or acid indigestion, antacids that neutralize stomach acid provide the fastest relief, typically within minutes. For a broader mix of symptoms, including nausea, diarrhea, and general upset, bismuth subsalicylate (the active ingredient in Pepto-Bismol) covers more ground. It treats diarrhea, heartburn, indigestion, and nausea. Adults can take it every 30 minutes to an hour as needed, up to a maximum of 16 doses in 24 hours.
For gas and bloating specifically, simethicone-based products help break up gas bubbles so they’re easier to pass. These are very safe and work quickly but won’t help with nausea or diarrhea.
Signs That Need Medical Attention
Most stomach upset passes within a few hours to a couple of days. But certain symptoms signal something more serious. Seek emergency care if you’re vomiting blood, notice black or bloody stool, have a swollen and tender abdomen, experience chest or shoulder pain alongside stomach pain, feel short of breath or dizzy, or develop a high fever. Persistent vomiting that won’t let up also warrants a call to your doctor, both because it can cause dangerous dehydration and because it may point to something beyond a simple upset stomach.
