Most stomach pain resolves on its own within a few hours using simple measures: applying heat, adjusting what you eat, and resting your digestive system. The right approach depends on what’s causing the pain, where you feel it, and how severe it is. Here’s what actually works and when to take things more seriously.
Where the Pain Is Tells You a Lot
Your abdomen houses dozens of organs, and pain in different areas points to different sources. Upper-right pain often involves the liver, gallbladder, or the first section of the small intestine. Upper-left pain can relate to the stomach, spleen, or pancreas. Lower-right pain is the classic location for appendicitis, while lower-left pain frequently comes from constipation or, in women, reproductive organs.
Pain that stays in one spot tends to come from a specific organ. Pain that moves around or feels generalized is more likely gas, bloating, or a stomach virus. If your pain started near your belly button and has migrated to the lower right side, that pattern is a hallmark of appendicitis and worth getting checked quickly.
Apply Heat to the Painful Area
A heating pad or hot water bottle is one of the most effective immediate remedies. Research from University College London found the molecular reason this works: heat above 40°C (104°F) applied to the skin activates heat receptors that essentially switch off pain signals from internal organs. The effect can last up to an hour. Place a heating pad or warm towel over the painful area, keep a layer of fabric between the heat source and your skin, and reapply as needed. This works especially well for cramping, gas pain, and menstrual-related stomach pain.
What to Eat (and What to Skip)
The old advice to eat only bananas, rice, applesauce, and toast (the BRAT diet) is outdated. While those foods are gentle on the stomach, there’s no research showing they speed recovery compared to a broader bland diet. Harvard Health notes that you can follow that restricted approach for a day or two if you have food poisoning or a stomach virus, but there’s no need to limit yourself so narrowly.
Better options include brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereals. Once your stomach settles, add back foods that provide protein and nutrients: cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken, fish, and eggs. These are all easy to digest while giving your body what it needs to recover. Avoid fried foods, dairy, caffeine, alcohol, and anything spicy until you feel consistently better.
Ginger and Peppermint for Nausea and Cramping
Ginger has genuine anti-nausea properties, backed by clinical trials. The active compounds (gingerols and shogaols) calm the digestive tract. Effective doses in studies ranged from 250 mg to 1 g per day, split into three or four doses, with no added benefit from going above 1 g. You can get this from ginger tea, ginger chews, or capsules. Fresh ginger steeped in hot water for 10 minutes works well.
Peppermint oil relaxes the smooth muscle of the digestive tract by blocking calcium channels in the gut wall, which reduces cramping and spasms. If you use capsules, look for enteric-coated versions (0.2 to 0.4 mL of oil, three times daily) so the oil releases in your intestines rather than your stomach, where it can worsen heartburn. Peppermint tea is a gentler alternative, though less concentrated.
Over-the-Counter Medications That Help
The right medication depends on the type of pain you’re experiencing.
- Antacids (like Tums or Gaviscon) neutralize stomach acid and work fast. Taken before a meal, they provide about 40 to 60 minutes of relief. Taken after a meal, they can last up to three hours. Best for heartburn, acid reflux, or a burning sensation in the upper stomach.
- H2 blockers (like famotidine/Pepcid) reduce acid production and last longer than antacids. Good for recurring heartburn or pain that antacids don’t fully control.
- Proton pump inhibitors (like omeprazole/Prilosec OTC) suppress acid production for a longer duration than H2 blockers. These are designed for frequent heartburn, not occasional stomach pain.
- Simethicone (Gas-X) breaks up gas bubbles and helps with bloating and pressure-type pain.
- Bismuth subsalicylate (Pepto-Bismol) coats the stomach lining and helps with nausea, indigestion, and diarrhea.
Avoid ibuprofen and aspirin when your stomach hurts. Both irritate the stomach lining and can make things worse. If you need a pain reliever, acetaminophen (Tylenol) is easier on the stomach.
Other Techniques Worth Trying
Lying on your left side can help trapped gas move through the colon more easily due to the anatomy of the large intestine. Gentle movement, like a slow walk around the block, stimulates digestion and can relieve bloating faster than staying in bed. Deep, slow breathing activates the body’s rest-and-digest response and can reduce the muscle tension that worsens cramping. Pulling your knees to your chest while lying on your back compresses the abdomen gently and helps release gas.
Stay hydrated, but take small sips rather than drinking large amounts at once. If you’re vomiting, wait 15 to 30 minutes after the last episode before trying clear fluids. Water, diluted electrolyte drinks, or clear broth are easiest to keep down.
Common Causes and How They Feel
Gas and bloating cause pressure and sharp, shifting pains that move around the abdomen. Indigestion (dyspepsia) produces a burning or gnawing feeling in the upper stomach, often after eating. Gastritis, or inflammation of the stomach lining, feels similar but tends to be more persistent and can worsen with spicy or acidic foods. Constipation creates cramping and pressure, usually in the lower left abdomen.
Irritable bowel syndrome causes recurring episodes of cramping, bloating, and changes in bowel habits. Gastroenteritis (stomach flu) brings on sudden nausea, vomiting, diarrhea, and cramping that typically resolve within one to three days. Menstrual cramps cause lower abdominal pain that can radiate to the back and thighs. Food intolerances, particularly to lactose or gluten, produce bloating, gas, and cramping that follow a pattern tied to specific foods.
Signs That Need Medical Attention
Most stomach pain is harmless, but certain patterns signal something more serious. Get to an emergency room if your pain comes with vomiting you can’t stop, an inability to keep any liquids down, or if you’re constipated with severe pain and can’t pass a bowel movement at all. Pain that started suddenly and has gotten steadily worse over hours, especially if it’s localizing to one specific area, warrants urgent evaluation.
Appendicitis often begins as vague pain near the belly button that shifts to the lower right within hours. It worsens with movement, coughing, or deep breaths. Acute pancreatitis typically presents as upper abdominal pain that gets worse after eating and may include nausea, fever, and a rapid pulse. If you’ve had abdominal surgery in the past, take new or unusual pain more seriously, as adhesions and obstructions are more common.
Stomach Pain in Children
Kids get stomach aches frequently, and most are caused by constipation, gas, or mild viral infections. The key warning signs in children are different from adults. A child who refuses to move, won’t walk or hop, or lies very still is showing signs that something more serious may be happening. Vomiting that contains green or yellow bile (not just food) is a red flag at any age but especially in children, as it can indicate a bowel obstruction.
Appendicitis in children under five is tricky because it often doesn’t follow the classic pattern. Young children may present with fever, vomiting, and diarrhea that looks like a regular stomach bug, which is why appendicitis in this age group is frequently diagnosed late. If a child’s pain is getting worse rather than better over several hours, or if they develop a rigid, tender belly, seek medical care promptly.
