Most stomach aches can be relieved at home within a few hours using a combination of heat, gentle movement, the right fluids, and careful food choices. The best approach depends on what’s causing your discomfort, whether that’s gas, indigestion, nausea, or something you ate. Here’s what actually works.
Apply Heat to Your Abdomen
A heating pad or hot water bottle is one of the simplest and most effective tools for stomach pain. Research from University College London found the molecular basis for why this works: heat above 40°C (104°F) applied to the skin activates heat receptors at the site of internal injury, essentially switching off the pain signals. The effect can last up to an hour.
This is especially useful for cramping pain caused by temporary reductions in blood flow or over-distension of hollow organs like the bowel. Wrap a heating pad in a towel, place it on your abdomen, and lie down. If you don’t have a heating pad, fill a sock with rice, microwave it for a minute or two, and use that instead.
Move Gas Along With Gentle Movement
If your stomach ache involves bloating or trapped gas, staying still on the couch can make it worse. A short walk helps stimulate the natural muscular contractions that push gas through your digestive tract. Even five to ten minutes can make a noticeable difference.
Certain yoga poses work particularly well because they relax the hips, lower back, and abdominal muscles simultaneously:
- Knee-to-chest pose: Lie on your back and pull both knees toward your chest, holding for 30 seconds. This stretches the lower back and compresses the abdomen gently.
- Child’s pose: Kneel on the floor, sit back on your heels, and fold forward with your arms extended. This relaxes the hips and lower back, helping gas move through the bowels.
- Happy baby pose: Lie on your back, grab the outsides of your feet, and pull your knees toward your armpits. This relieves pressure in the lower back and groin.
You can also massage your abdomen in a clockwise direction, moving from right to left. This follows the natural path of your colon and can help push gas toward the exit.
Choose the Right Over-the-Counter Option
Not all stomach medicines do the same thing, and picking the wrong one means waiting around while nothing improves.
Antacids (like Tums or Rolaids) work by directly neutralizing the acid already in your stomach. They act fast, usually within minutes, and are your best bet for occasional heartburn or that burning feeling after a heavy meal. Their relief is real but short-lived.
H2 blockers (like famotidine) reduce acid production by blocking one of the signals that tells your stomach to make acid. They also have a quick onset and can be taken as needed, making them a good choice when you know a trigger is coming or when antacids aren’t lasting long enough.
Proton pump inhibitors work differently. They shut down the acid-producing pumps in your stomach lining and need to be taken 30 to 60 minutes before eating. They’re the most powerful acid reducers available over the counter, but they’re designed for repeated use over days or weeks, not for quick relief of a single stomach ache.
For nausea, diarrhea, or general upset stomach, bismuth subsalicylate (the active ingredient in Pepto-Bismol) is a common option for adults. It should not be given to children under 12, and it should never be used for nausea or vomiting in children or teenagers who have or are recovering from the flu or chickenpox due to the risk of Reye’s syndrome.
Try Ginger or Peppermint
Ginger has genuine anti-inflammatory properties. Its active compounds reduce inflammation in the gut lining and have both muscle-relaxing and muscle-stimulating effects on the digestive tract, which can help whether your stomach is cramping or sluggish. Fresh ginger tea is the easiest way to use it: slice a thumb-sized piece, steep it in hot water for five to ten minutes, and sip slowly.
Peppermint works through a different mechanism. The menthol in peppermint blocks calcium channels in the smooth muscle of your gut, which directly relaxes intestinal spasms. It also has mild pain-relieving effects by interfering with pain signaling pathways. Peppermint tea is a reasonable choice for cramping and bloating. Enteric-coated peppermint oil capsules, taken before meals, are a more concentrated option that delivers the menthol directly to the intestines. One note: peppermint can worsen heartburn by relaxing the valve between your esophagus and stomach, so skip it if acid reflux is your problem.
Stay Hydrated the Right Way
If your stomach ache involves vomiting or diarrhea, dehydration becomes a real concern quickly. What you drink matters as much as how much. Sodas, undiluted fruit juice, and sports drinks contain too much sugar, which can actually pull water into your intestines and make diarrhea worse through osmotic effects.
The best option is an oral rehydration solution like Pedialyte, which contains the right balance of sodium, potassium, and glucose to replace what you’re losing. You don’t need to buy a commercial product, though. The World Health Organization’s formula is simple: mix water with a small amount of salt and sugar in precise proportions. What matters is keeping the sugar concentration low (around 2%) and including enough sodium to drive absorption.
Sip small amounts frequently rather than gulping large quantities. If you’re vomiting, try a tablespoon every few minutes. Your stomach tolerates small, steady volumes far better than a full glass at once.
Eat Carefully as You Recover
The old advice to eat only bananas, rice, applesauce, and toast (the BRAT diet) is fine for a day or two, but it’s too nutritionally limited to follow for longer. Harvard Health Publishing notes there’s no need to restrict yourself to just those four foods. Other easy-to-digest options include brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereals.
Once your stomach starts to settle, gradually add more nutritious foods: cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. These give your body the protein and nutrients it needs to recover without irritating your gut.
What to avoid until you’re fully better: dairy products, fried foods, anything high in sugar, acidic foods like citrus and tomato sauce, spicy foods, alcohol, and caffeine. High-fiber foods like leafy greens, nuts, seeds, beans, and fruit skins are also worth skipping temporarily since insoluble fiber can be hard on an irritated digestive system.
Signs That Need Emergency Attention
Most stomach aches resolve on their own, but certain patterns signal something more serious. Get to an emergency room if the pain is so severe it interrupts your ability to function, if you can’t keep any liquids down, or if you’re unable to have a bowel movement and are in significant pain.
Appendicitis has a distinctive progression worth knowing. It typically starts as a vague, nagging pain around the belly button, often accompanied by loss of appetite. Over the next 12 to 24 hours, the pain migrates to the right lower abdomen and becomes progressively more severe. It gets worse when you move, cough, sneeze, or take a deep breath. Other symptoms include nausea, vomiting, fever, abdominal swelling, and constipation or diarrhea. This progression, from mild and central to severe and lower-right, is the pattern that should prompt an immediate trip to the ER.
If you’ve had abdominal surgery in the past, or if your current pain feels similar to a previous episode but more severe or different in character, that also warrants urgent evaluation.
