You’re hunched over. Your middle feels like it’s being wrung out like a wet dishcloth, or maybe it’s that slow, rhythmic churning that makes you wonder if you’re about to see your lunch again. We’ve all been there. It’s miserable. But honestly, most of the advice floating around the internet about what to do with upset stomach is either outdated or just plain wrong. People tell you to chug ginger ale or eat a piece of dry toast, but if you’re dealing with specific types of gastritis or a nasty bout of norovirus, those "cures" can actually irritate your gut lining further.
The reality is that your digestive tract is a complex nervous system of its own—often called the "second brain." When it revolts, it’s usually for a specific reason. It might be a reaction to a toxin, a viral invader, or just your gallbladder throwing a tantrum because you ate too much fried food. You need a strategy that matches the symptoms.
Stop Reaching for the Ginger Ale Immediately
Most people think ginger ale is the holy grail for nausea. It isn’t. Look at the label on a standard bottle of Canada Dry or Seagram’s. You’ll find high fructose corn syrup, citric acid, and "natural flavors." There is almost zero actual ginger in most commercial sodas. The carbonation might help you burp and relieve some pressure, but the massive hit of sugar can actually trigger "osmotic diarrhea." Basically, sugar pulls water into your intestines, making a loose stool situation way worse.
If you want the benefits of ginger, you need the real deal. Research published in the journal Nutrients has shown that gingerols and shogaols—the active compounds in ginger—actually speed up gastric emptying. This is huge. If your stomach is upset because food is just sitting there like a brick, ginger helps move it along.
Try this instead: shave a teaspoon of fresh ginger root into a mug of hot water. Let it steep for five minutes. Sip it slowly. No sugar. No bubbles. Just the root.
Understanding the "Why" Behind the Ache
Is it a sharp pain? A dull burn? Or that weird, fluttery nausea?
If you have a burning sensation high up in your chest or throat, that’s likely acid reflux or GERD. In that case, lying down flat is the worst thing you can do. Gravity is your friend here. Prop yourself up with pillows. Conversely, if you have sharp pains in the lower right quadrant of your abdomen, stop reading this and go to the ER—that’s where your appendix lives, and you don't want to mess with that.

For a standard "I ate something bad" or "I have a bug" situation, your body is trying to purge. Let it. Don't take anti-diarrheal meds like Imodium the second you feel a cramp. If your body is trying to get rid of Salmonella or E. coli, those meds lock the bacteria inside your system for longer. It’s better to stay hydrated and let the process happen, as long as you aren't showing signs of severe dehydration.
The Myth of the BRAT Diet
For decades, doctors pushed the BRAT diet: Bananas, Rice, Applesauce, and Toast.
The American Academy of Pediatrics actually stopped recommending it as a primary treatment years ago. Why? Because it’s nutritionally "incomplete." While those foods are easy to digest, they lack the protein and healthy fats your gut lining needs to actually repair itself.
- Bananas: Good for potassium, but can be heavy for some.
- Rice: White rice is fine, but it’s just starch.
- Applesauce: High in pectin, which helps firm up stools, but also high in sugar.
- Toast: Contains gluten, which is a common irritant when your gut is already inflamed.
Instead of strictly sticking to BRAT, focus on "low-residue" foods. Think soft-boiled eggs or a very simple bone broth. Bone broth is a powerhouse because it contains collagen and glutamine, which help "seal" the junctions in your intestinal lining that get loose during an inflammatory flare-up.
The Heat Factor: Why a Heating Pad Actually Works
It’s not just a placebo. When you place a heating pad or a hot water bottle on your abdomen, you’re increasing blood flow to the area. This helps the smooth muscles of the gut relax. Think of it like a massage for your internal organs.
A study from University College London found that heat doesn't just provide a distracting sensation; it actually shuts down the pain at a molecular level. Heat at about 40°C (104°F) deactivates pain receptors that detect chemical messengers of pain. It’s basically a natural off-switch for those localized cramps.

Peppermint is a Double-Edged Sword
Peppermint oil is incredible for IBS (Irritable Bowel Syndrome). It’s an antispasmodic. But here is the catch: if your upset stomach is caused by acid reflux or heartburn, peppermint will make it a thousand times worse.
Peppermint relaxes the Lower Esophageal Sphincter (LES). That’s the "trap door" between your stomach and your throat. When that door relaxes, stomach acid splashes up into your esophagus.
So, if you’re gassy and bloated? Peppermint tea is great.
If you’re feeling a "burning" sensation? Avoid it at all costs.
When to Actually Call a Doctor
Don't be a hero. Most stomach issues resolve in 24 to 48 hours. But there are red flags that mean your DIY approach isn't enough.
- High Fever: Anything over 102°F (38.9°C) suggests a serious infection.
- Blood: If you see blood in your stool or vomit (it might look like coffee grounds), get help.
- Dehydration Signs: If your urine is dark brown, or if you haven't peed in 8 hours, you might need an IV.
- Rebound Tenderness: This is a big one. Press down on your stomach. If it hurts more when you release the pressure than when you're pressing down, that can indicate peritonitis or appendicitis.
Probiotics: Timing is Everything
People often start popping probiotic pills the second their stomach feels off. This is usually a waste of money. If you’re currently vomiting or have active diarrhea, those expensive bacteria are just going to pass right through you.
The time for probiotics is the "recovery phase." Once you can hold down solid food, that’s when you introduce things like kefir, sauerkraut, or a high-quality supplement containing Lactobacillus rhamnosus GG. This helps restore the microbiome that was just decimated by the illness.

Think of it like replanting a garden after a flood. You don't plant seeds while it's still raining; you wait for the water to recede.
The Impact of Stress on Your Gut
Sometimes what to do with upset stomach isn't about what you eat, but what you're thinking. The vagus nerve connects your brain directly to your digestive tract. This is why you get "butterflies" when you’re nervous.
If your stomach is constantly upset but doctors can't find a physical cause, you might be dealing with functional dyspepsia. Essentially, your gut is hyper-sensitive. In these cases, deep diaphragmatic breathing—breathing so deep your belly expands—can stimulate the vagus nerve and signal your digestive system to "rest and digest" rather than "fight or flee."
Practical Next Steps
If you’re hurting right now, here is the immediate checklist:
- Sip, don't chug. Take small sips of room-temperature water or an oral rehydration solution (like Pedialyte). Cold water can cause the stomach to cramp further.
- Apply heat. Get a heating pad on your midsection for 20 minutes on, 20 minutes off.
- Check your meds. Avoid NSAIDs like Ibuprofen or Aspirin. These are notorious for irritating the stomach lining. Stick to Acetaminophen (Tylenol) if you have a fever, but only if necessary.
- Vertical or Horizontal? If it’s reflux, stay upright. If it’s cramps, lie on your left side. The "left side" position is anatomically superior because of the way the stomach is shaped; it keeps the stomach contents below the esophagus and helps gas move through the large intestine.
- Keep a log. If this happens often, write down what you ate 4-6 hours before the pain started. Sensitivities to FODMAPs (certain fermentable carbohydrates) often manifest several hours after a meal, not immediately.
Understanding your body’s signals is the difference between a 24-hour bug and a week of agony. Listen to the type of pain you're having, skip the sugary sodas, and give your digestive system the space it needs to reset. Most of the time, the best thing you can do for an upset stomach is to stop over-treating it and let your natural defenses do their job.
