Most stomach pain responds well to simple measures you can start at home: applying heat, sipping the right fluids, adjusting your position, and choosing the correct over-the-counter remedy for your specific symptom. The key is matching the relief strategy to what’s actually causing the discomfort, whether that’s gas, acid, cramping, or nausea.
Apply Heat to Your Abdomen
A heating pad or hot water bottle is one of the fastest, simplest ways to ease stomach cramping. Research from University College London found the molecular reason this works: heat above 40°C (104°F) activates receptors in the skin that directly block pain signals from damaged or irritated tissue underneath. Those heat receptors essentially shut down the chemical messengers responsible for sending pain to your brain, providing relief for up to an hour.
Place a heating pad or a warm (not scalding) water bottle over the area that hurts. A thin layer of clothing or a towel between the heat source and your skin prevents burns. You can reapply as needed, and many people find that lying down with heat while resting is the most comfortable combination.
Stay Hydrated, Especially With Vomiting or Diarrhea
If your stomach pain comes with vomiting or diarrhea, fluid loss is a real concern. The priority is replacing both water and electrolytes. If you’re vomiting, sip small amounts of clear liquids rather than drinking a full glass at once. Water, broth, fruit juice, and sports drinks all work for most adults. Saltine crackers can help replace electrolytes too.
For young children, oral rehydration solutions like Pedialyte are the best option. Infants should continue breast milk or formula as usual. Older adults and anyone with a weakened immune system should also lean toward oral rehydration solutions rather than water alone, since they’re more vulnerable to dehydration.
Try Ginger, Peppermint, or Chamomile
Ginger is a well-established remedy for nausea and general stomach upset. You can chew crystallized ginger, take it as a supplement, or steep fresh slices in hot water for tea. Peppermint and chamomile tea both relax the muscles of the digestive tract, which reduces cramping and intestinal spasms. If your pain feels like tightness or squeezing, these are particularly worth trying. Brew a cup and sip it warm rather than gulping it down.
Adjust Your Position
How you sit or lie down matters more than most people realize. If your pain involves heartburn or acid reflux, sleeping or lying on your left side is significantly better than your right. Right-side lying tends to worsen reflux symptoms. This applies whether you have chronic GERD or just occasional heartburn from a heavy meal. Propping your head and upper body slightly with an extra pillow can also keep acid from traveling upward.
If your pain is from trapped gas or bloating, gentle movement helps more than staying still. A short, slow walk can get things moving through your digestive tract. Specific yoga poses are also effective for releasing gas: Wind-Relieving Pose (lying on your back and pulling your knees to your chest), Child’s Pose, and Happy Baby Pose (lying on your back with knees bent along the sides of your body, soles of the feet facing the ceiling) all help relax the abdomen and encourage gas to pass. Even a simple two-knee spinal twist, where you lie on your back and drop both bent knees to one side, can bring quick relief.
Choose the Right Over-the-Counter Remedy
Different types of stomach pain call for different medications, and picking the wrong one means waiting for relief that won’t come.
For nausea, diarrhea, or general upset: Bismuth subsalicylate (the active ingredient in Pepto-Bismol and store-brand equivalents) treats a wide range of symptoms including nausea, indigestion, heartburn, gas, belching, and diarrhea. It’s a good first choice when you’re not sure exactly what’s wrong but your stomach just feels off.
For heartburn and acid-related pain: Antacids (like Tums or Rolaids) neutralize stomach acid quickly and provide near-immediate but short-lived relief. If you need longer coverage, H2 blockers take about an hour to kick in but then work for four to ten hours. If you know a meal is likely to trigger heartburn, taking an H2 blocker 30 to 60 minutes before eating gives it time to work before the pain starts.
For cramping and spasms: Heat, peppermint tea, and gentle stretching are often more effective than medication. Standard pain relievers like ibuprofen and aspirin can actually irritate the stomach lining, so avoid them for abdominal pain unless you know the cause and have been advised otherwise.
What to Eat (and What to Skip)
You may have heard of the BRAT diet (bananas, rice, applesauce, toast) for an upset stomach, but current guidance from the National Institute of Diabetes and Digestive and Kidney Diseases doesn’t recommend following a restricted diet during stomach illness. Research shows it doesn’t help recovery. Once your appetite returns, you can generally go back to eating your normal diet, even if diarrhea hasn’t fully resolved.
That said, certain foods are more likely to make things worse while you’re still symptomatic. Caffeine, high-fat foods (fried food, pizza, fast food), very sugary drinks, and dairy products are the main culprits. Lactose in milk and dairy can be especially problematic because some people have trouble digesting it for a month or more after a stomach illness. If dairy seems to trigger more pain or diarrhea during recovery, that’s a common temporary reaction.
Where the Pain Is Can Tell You What’s Wrong
Paying attention to the location of your pain helps you understand what might be causing it and whether you need more than home remedies.
- Upper left abdomen: This is where your stomach and pancreas sit. Pain here often relates to indigestion, gastritis, or stomach ulcers.
- Upper center abdomen: Pancreatitis, an inflammation of the pancreas, typically shows up here. This pain is often severe and may radiate to your back.
- Lower right abdomen: Home to the lower bowel and colon, but also the appendix. Persistent or worsening pain here, especially with fever, warrants prompt medical attention.
- Lower abdomen generally: Inflamed pouches along the colon wall (diverticulitis) cause sharp pain in the lower abdomen that can feel very similar to appendicitis.
- Pain throughout the abdomen: Widespread cramping, nausea, and diarrhea can point to food-related causes, viral illness, or conditions like celiac disease.
Signs You Need Emergency Care
Most stomach pain resolves on its own or with the strategies above. But certain symptoms signal something more serious. Get to an emergency room if you experience severe pain that makes it difficult to move, eat, or drink. Sudden-onset stomach pain (fine one moment, doubled over the next) is also a red flag, as are a high fever, blood in your stool or vomit, and abdominal pain following any kind of physical trauma to the area.
One detail that surprises many people: heart attacks can sometimes present as severe nausea or pain in the upper abdomen, just below the rib cage. If upper abdominal pain feels unusual or is accompanied by chest pressure, shortness of breath, or lightheadedness, treat it as a cardiac concern rather than a stomach problem.
