You're hunched over. Maybe it’s a sharp cramp, or perhaps it’s that slow, rolling wave of nausea that makes you regret every life choice you made at dinner last night. We've all been there. Most people just reach for a pink liquid or a ginger ale and hope for the best, but the truth is that what is good for a upset stomach depends entirely on why your gut is screaming at you in the first place.
If you’ve got acid reflux, a glass of orange juice is basically liquid fire. If you’ve got a viral bug, slamming a heavy meal—even a "healthy" one—is a disaster. It's about context.
The Science of Settling Your Gut
Let's talk about ginger. It’s the gold standard for a reason. Real ginger contains compounds called gingerols and shogaols. These aren't just fancy names; they actually speed up gastric emptying. Basically, they tell your stomach to move its contents along into the small intestine so things don't just sit there and ferment or irritate the lining.
But here is the kicker: most "ginger ale" you buy at the gas station has zero actual ginger in it. It’s mostly high-fructose corn syrup and carbonation. The bubbles might make you burp, which provides a tiny bit of pressure relief, but the sugar can actually trigger more bloating. Honestly, you're better off shaving fresh ginger into hot water.
Then there is the BRAT diet. You probably grew up on this—Bananas, Rice, Applesauce, Toast. For decades, doctors swore by it. However, the American Academy of Pediatrics has actually stepped back from recommending it as a long-term solution. Why? Because it's incredibly low in protein and fat, which your body actually needs to repair the intestinal wall after a bout of gastroenteritis. It’s fine for the first six hours when you can't keep anything down, but don't stay on it for three days. You'll just end up weak and malnourished.
Peppermint: The Double-Edged Sword
Peppermint is fascinating. It’s an antispasmodic. This means it relaxes the muscles in your digestive tract. If you have Irritable Bowel Syndrome (IBS) or lower intestinal cramping, peppermint oil enteric-coated capsules are a godsend. They bypass the stomach and open up in the intestines where they can do the most work.
But wait.
If your "upset stomach" is actually heartburn or GERD, peppermint is your worst enemy. Because it relaxes muscles, it can also loosen the lower esophageal sphincter. That’s the "trap door" that keeps stomach acid down. If that door relaxes, acid splashes up. Now you have a calm gut but a burning throat. Not a great trade-off.

What is Good for a Upset Stomach When It’s Gas and Bloating
Sometimes the pain isn't "sick" pain—it's "stuck" pain.
Gas can be excruciating. It can even mimic chest pain or gallbladder issues. In these cases, movement is often better than any pill. A 15-minute walk helps the peristalsis—the wave-like contractions of your gut—push that air through.
If you're looking for a supplement, Simethicone is the active ingredient in products like Gas-X. It doesn't actually make the gas disappear into thin air. Instead, it acts as a surfactant. It breaks up tiny, painful gas bubbles into larger ones that are easier to pass. It’s simple chemistry, really.
Chamomile tea is another heavy hitter here. While ginger is "hot" and stimulating, chamomile is a carminative. It soothes the mucous membranes. If your stomach feels "tight" or "tied in knots" due to stress, chamomile is usually the better choice over ginger. It interacts with GABA receptors in the brain, helping you relax both mentally and physically.
Dealing with the "Stomach Flu" (Gastroenteritis)
First off, it’s not the flu. Influenza is respiratory. What you likely have is Norovirus or Rotavirus.
When you’re losing fluids from both ends, hydration is the only thing that matters. But don't just chug plain water. If you drink a liter of plain water while you're severely dehydrated, you risk hyponatremia—diluting your body's sodium levels too much.
You need electrolytes. Specifically, a balance of sodium, potassium, and a little bit of glucose. The glucose isn't just for energy; it actually acts as a carrier molecule that helps your cells pull in the sodium and water more efficiently. This is why the World Health Organization’s oral rehydration salts work so well.

- Sip, don't chug. A tablespoon every five minutes is better than a glass every hour.
- Temperature matters. Room temperature liquids are less shocking to the stomach lining than ice-cold ones.
- Avoid dairy. Even if you aren't lactose intolerant, a viral infection can temporarily "knock off" the lactase enzymes in your gut, meaning a glass of milk will lead to immediate, explosive regret.
The Role of Probiotics
Should you take probiotics while your stomach is upset?
Probably not during the acute phase. If you're vomiting, a pill isn't going to stay down. However, specific strains like Saccharomyces boulardii—which is actually a beneficial yeast—have been shown in clinical trials to significantly shorten the duration of diarrhea. Unlike bacterial probiotics, S. boulardii isn't affected by antibiotics, making it a powerhouse if your stomach issues are caused by medication.
When the "Upset" is Actually Gastritis
Gastritis is inflammation of the stomach lining. It feels like a gnawing or burning ache. This is often caused by overusing NSAIDs (like ibuprofen or aspirin) or an H. pylori infection.
In this scenario, what is good for a upset stomach is anything that coats and protects.
Bone broth is excellent here. It's rich in glycine and glutamine, amino acids that are foundational for gut lining repair.
Licorice root—specifically DGL (Deglycyrrhizinated Licorice)—is another expert-level move. DGL increases mucus production in the stomach, providing a natural buffer against acid. You chew it about 20 minutes before a meal. It tastes a bit like dirt and candy mixed together, but it works.
Myths That Need to Die
- "Feed a cold, starve a fever." This is nonsense. Your gut doesn't care about the old wives' tale. If you're hungry and can keep food down, eat. If the thought of food makes you gag, don't. Listen to your enteric nervous system.
- Apple Cider Vinegar fixes everything. ACV is very acidic. If your upset stomach is caused by an ulcer or gastritis, drinking vinegar is like putting lemon juice on a paper cut. Stop doing it just because a TikToker told you to.
- Toast has to be burnt. Some people think the "char" acts like activated charcoal. It doesn't. Burnt toast contains acrylamide, which isn't great for you. If you need charcoal for poisoning, go to the ER for the medical-grade stuff.
Practical Steps for Immediate Relief
If you are currently suffering, stop reading and follow this sequence.
Step 1: The 30-Minute Pause. Stop putting anything in your stomach. No water, no crackers, nothing. Let the gastric muscles stop spasming.
Step 2: Micro-Sips. After the pause, take one sip of a room-temperature electrolyte drink or ginger tea. Wait ten minutes. If it stays down, take two sips.

Step 3: The Heat Check. Apply a heating pad to your abdomen. The heat increases blood flow to the area and can physically relax the smooth muscle tissue of the stomach. This is often more effective than any over-the-counter pill for cramping.
Step 4: Assess the Pain. If the pain is localized in the lower right quadrant, or if you have a high fever and a rigid abdomen, stop home remedies. That’s potentially appendicitis. If you're also experiencing chest tightness or pain radiating to the jaw, call emergency services—sometimes a heart attack masks itself as "indigestion."
Moving Forward
Once you're over the hump, don't jump straight back into a spicy burrito. Your gut is sensitive. Stick to "low-residue" foods for 24 hours. Think soft-cooked carrots, plain sourdough, or a bit of plain chicken.
Avoid caffeine and nicotine. Both are stimulants that can kickstart your gut into overdrive before it's ready to handle the load.
For chronic issues, start a food diary. Often, what we think is a random "upset stomach" is actually a delayed reaction to something like FODMAPs (fermentable carbohydrates found in onions and garlic) or a slow-developing sensitivity to gluten or dairy. Identifying the pattern is the only way to stop the cycle.
Stick to the basics: heat, hydration, and real ginger. Most of the time, your body just needs you to get out of its way so it can do the repair work it was designed for.
