Most stomach pain improves with a handful of simple measures: resting your gut, applying heat, staying hydrated, and choosing the right over-the-counter remedy for the type of discomfort you’re feeling. The trick is matching the relief method to what’s actually going on, because a gassy, bloated stomach calls for a different approach than acid-related burning or cramping from a stomach bug.
Rest Your Gut With Easy-to-Digest Foods
When your stomach hurts, the simplest first step is to stop eating for a short time or switch to foods that require minimal digestive effort. Crackers, bananas, plain rice, brothy soups, oatmeal, and boiled potatoes all fit the bill. You may have heard of the BRAT diet (bananas, rice, applesauce, toast), and it’s fine for a day or two during a stomach bug or food poisoning, but there’s no reason to limit yourself to just those four items. A slightly broader menu of bland foods gives your body more protein and nutrients to recover with.
Once the worst passes, usually within a day or two, you can start adding back more nutritious options: cooked carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. These are still gentle on digestion but provide the building blocks your body needs after a rough stretch.
Apply Heat to Your Belly
A heating pad or warm water bottle pressed against your abdomen isn’t just comforting. Research from University College London found that heat above 40°C (about 104°F) applied to the skin near the source of internal pain actually switches on heat receptors that block pain signals at a molecular level, working in a similar way to painkillers. This is especially effective for cramping pain, the kind caused by temporary changes in blood flow to organs like the bowel, or by over-distension from gas and bloating.
A warm bath works the same way. If you’re using an electric heating pad, keep a cloth layer between it and your skin and avoid falling asleep with it on to prevent burns.
Stay Hydrated, Especially During Vomiting or Diarrhea
Stomach pain that comes with vomiting or diarrhea can drain fluids fast, and dehydration itself makes nausea and cramping worse. Plain water helps, but if you’ve been losing fluids for more than a few hours, an oral rehydration solution replaces the electrolytes your body is shedding. Products like Pedialyte are widely available and designed for exactly this purpose. Sip small amounts frequently rather than gulping large volumes, which can trigger more nausea.
Sports drinks are a common substitute, but they tend to contain more sugar and less sodium than a proper rehydration formula. They’ll do in a pinch, but a pharmacy-grade oral rehydration solution is more effective when fluid loss is significant.
Choosing the Right Over-the-Counter Remedy
For Acid and Heartburn
Three types of acid-reducing medications exist, and they work at different speeds and last for different durations. Antacids (like Tums or Rolaids) neutralize acid that’s already sitting in your stomach. They act within minutes but wear off quickly, making them best for occasional flare-ups. H2 blockers (like famotidine) work fairly quickly by blocking the chemical signal that tells your stomach to produce acid, offering longer relief than antacids. Proton pump inhibitors, or PPIs (like omeprazole), are the most powerful option. They shut down the acid-producing pumps in your stomach lining at the final step of production. PPIs are slower to kick in but provide the longest-lasting suppression. They’re designed for frequent heartburn rather than one-off episodes.
For Gas and Bloating
Simethicone (sold as Gas-X or similar brands) works by merging the small gas bubbles trapped in your gut into larger ones that are easier to pass. It typically starts working within 30 minutes. It won’t help with acid pain or cramping, but if your discomfort feels like pressure, fullness, or bloating, it’s the right tool.
Peppermint for Cramping and Spasms
Peppermint oil relaxes the smooth muscle lining your digestive tract by reducing calcium flow into muscle cells, which is what drives those muscles to contract. The effect is similar to a class of prescription muscle relaxants. This makes peppermint particularly useful for spasm-type pain: the kind that comes in waves, often associated with irritable bowel syndrome or general intestinal cramping.
Peppermint tea offers a milder version of this effect. For more targeted relief, delayed-release peppermint oil capsules are available over the counter and are designed to dissolve in the intestines rather than the stomach, reducing the chance of heartburn (since relaxing the muscle at the top of the stomach can sometimes let acid creep upward).
Probiotics for Recurring Pain
If stomach pain is a regular occurrence rather than a one-time event, probiotics may help over the long term. A large meta-analysis published in The Lancet’s eClinicalMedicine found that specific strains can meaningfully reduce abdominal pain in people with irritable bowel syndrome. Not all probiotics are interchangeable, though. The strains with the strongest evidence for pain relief include Lactiplantibacillus plantarum 299v and Saccharomyces boulardii CNCM I-745. Generic “probiotic blend” supplements may or may not contain effective strains, so checking the label for specific strain names matters.
Probiotics won’t help with acute pain from food poisoning or a stomach bug. They’re a longer-term strategy for people whose gut tends to act up repeatedly.
Pain That Needs Medical Attention
Most stomach pain is temporary and harmless, but certain patterns signal something more serious. Sudden, severe abdominal pain that hits without warning should never be managed at home. The same applies to pain that steadily worsens over hours rather than coming and going.
Specific warning signs to watch for:
- Vomiting blood or vomit that looks like coffee grounds
- Blood in your stool or black, tarry stools
- Severe pain radiating to your back, groin, or legs, especially with faintness or nausea, which can indicate a ruptured blood vessel
- Fever combined with localized pain, particularly in the lower right abdomen (a classic appendicitis pattern)
Pain in different areas of the abdomen points to different organs. Upper right pain may involve the gallbladder or liver. Upper left pain can relate to the stomach lining or pancreas. Lower abdominal pain often involves the intestines or bladder. Location alone isn’t diagnostic, but it gives a useful starting point when describing symptoms to a healthcare provider.
