Most stomach aches can be treated at home with a combination of simple comfort measures, careful food choices, and the right over-the-counter medication for your specific symptoms. The key is matching your approach to the type of pain you’re experiencing, since a remedy that works for acid-related burning won’t necessarily help cramping from a stomach bug.
Start With Heat and Rest
One of the simplest and most effective first steps is placing a heating pad or warm water bottle on your abdomen. Heat above 40°C (104°F) applied to the skin near the source of internal pain activates heat receptors that block the chemical signals responsible for transmitting pain. Researchers at University College London found that these heat receptors essentially shut down the pain receptors that fire when cells are damaged or inflamed, which is why a warm compress can bring genuine relief and not just distraction.
Lie down in a comfortable position, either on your back with knees slightly bent or curled on your side. Tight clothing around your waist can increase pressure on an already irritated stomach, so switch to something loose. Give yourself 15 to 20 minutes with the heat before deciding whether you need medication.
Choose the Right Over-the-Counter Medication
Different stomach symptoms call for different medications, and grabbing the wrong one can leave you waiting for relief that never comes.
Antacids (like Tums or Rolaids) work by neutralizing stomach acid on contact. They’re your best option for heartburn, acid reflux, or a burning sensation in your upper abdomen. Relief is fast but tends to be short-lived.
Acid reducers (like famotidine) take longer to kick in but reduce the amount of acid your stomach produces over several hours. If you get heartburn frequently or antacids wear off too quickly, an acid reducer is the better choice.
Bismuth subsalicylate (Pepto-Bismol) covers the broadest range of symptoms: general upset stomach, nausea, indigestion, and diarrhea. Adults can take 2 tablets every 30 minutes to an hour as needed, up to 16 tablets in 24 hours. This medication 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.
Simethicone (Gas-X) targets bloating and gas pain specifically. If your stomach ache comes with a feeling of fullness, visible distension, or pressure that shifts around your abdomen, trapped gas is likely the culprit.
What to Eat and Drink
If you’re actively vomiting, skip solid food entirely and stick to small sips of clear liquids: water, ice chips, broth, diluted fruit juice, electrolyte drinks, or weak decaffeinated tea. Popsicles also count. Taking tiny sips every few minutes is far more effective than drinking a full glass, which can trigger more vomiting.
Once the worst passes, you can start with bland, easy-to-digest foods. You may have heard of the BRAT diet (bananas, rice, applesauce, toast), but the Cleveland Clinic and the American Academy of Pediatrics no longer recommend following it strictly because it lacks calcium, vitamin B12, protein, and fiber. It’s fine for the first day when you’re at your sickest, but staying on it longer than that can actually slow your recovery. Instead, expand to other gentle options like brothy soups, oatmeal, boiled potatoes, saltine crackers, and dry cereal.
As your stomach settles, add foods that are still soft but more nutritious: scrambled eggs, skinless chicken or turkey, and cooked vegetables. Until you feel fully recovered, avoid acidic foods, alcohol, caffeine, dairy, fried foods, spicy foods, and sugary items. These are the most common triggers for a relapse.
What the Location of Pain Can Tell You
Where your stomach ache sits can offer clues about what’s causing it, especially if home treatment isn’t working.
Pain in the upper right abdomen often involves the gallbladder or liver. Gallstones typically cause sharp pain after eating fatty meals, sometimes radiating to the right shoulder blade. Upper left pain is more commonly tied to the stomach itself (gastritis, ulcers) or occasionally the pancreas. Pain from a peptic ulcer often feels like burning and may improve or worsen with eating.
Lower right abdominal pain is the classic location for appendicitis, though it can start as a vague ache around the belly button before migrating. Lower left pain in adults over 40 is frequently related to diverticulitis, which causes steady pain along with fever and changes in bowel habits. Pain on either lower side in women of reproductive age could involve ovarian issues or, in rare cases, an ectopic pregnancy.
Generalized pain that’s hard to pinpoint is more typical of gas, a stomach virus, irritable bowel syndrome, or food-related upset. These are the stomach aches most responsive to home treatment.
When to Get Emergency Care
Most stomach aches resolve within a few hours. But certain patterns signal something that needs immediate medical attention. According to the American College of Emergency Physicians, you should seek emergency care if your pain is sudden and severe, or if it doesn’t ease within 30 minutes. Continuous severe pain accompanied by nonstop vomiting is a red flag for serious or life-threatening conditions.
Other warning signs that warrant urgent evaluation:
- Fever with abdominal pain, especially if the pain is localized to one area
- Blood in your stool or vomit
- Severe pain in the lower right abdomen with nausea, vomiting, or loss of appetite (possible appendicitis)
- Abdominal pain with vaginal bleeding in women of reproductive age (possible ectopic pregnancy)
- Swelling or visible distension of the abdomen that’s tender to touch
- Pain that wakes you from sleep
If Your Stomach Ache Keeps Coming Back
A stomach ache that recurs over weeks isn’t just a string of bad luck. Abdominal pain lasting more than three months is classified as chronic and typically requires investigation beyond home remedies. Common causes include irritable bowel syndrome, food intolerances (especially lactose or gluten), chronic gastritis, or peptic ulcers caused by H. pylori bacteria.
Pay attention to patterns. Pain that follows meals may point to a food trigger or gallbladder issue. Pain that improves after a bowel movement often suggests IBS. Burning that worsens on an empty stomach and improves with eating is a hallmark of duodenal ulcers. Keeping a simple log of when pain occurs, what you ate, and what made it better or worse gives your doctor far more useful information than a vague description of “stomach problems.”
