An upset stomach usually improves with a combination of simple home strategies: sipping clear fluids, eating bland foods, applying warmth, and sometimes reaching for an over-the-counter remedy. Most episodes resolve within a day or two without anything more than basic self-care. The specific approach that works best depends on whether your main symptom is nausea, cramping, bloating, or diarrhea.
Start With Clear Fluids and Small Sips
Dehydration is the biggest practical risk when your stomach is acting up, especially if vomiting or diarrhea is involved. Water, broth, and electrolyte drinks are your first line of defense. Take small, frequent sips rather than gulping a full glass, which can trigger more nausea. Ice chips work well if even small sips feel like too much.
Avoid alcohol, caffeine, and carbonated drinks until your stomach settles. Caffeinated beverages can increase stomach acid production, and carbonation adds gas to an already irritated digestive tract. Room-temperature or slightly warm liquids tend to be easier to tolerate than ice-cold ones.
What to Eat (and What to Skip)
You may have heard of the BRAT diet: bananas, rice, applesauce, and toast. While those foods are gentle on the stomach, following a strict BRAT diet is no longer recommended. The American Academy of Pediatrics notes it’s too restrictive and lacks the nutrients your gut needs to recover. Sticking to it for more than 24 hours may actually slow healing.
A better approach is to think of BRAT as a starting point, not a complete plan. Eat soft, bland foods like plain crackers, boiled potatoes, oatmeal, or skinless chicken. Once you can tolerate those, expand to a normal diet as soon as you feel ready. The goal is to get adequate nutrition back in without overwhelming your digestive system. Avoid greasy, spicy, or heavily seasoned foods until you’re feeling fully recovered.
Peppermint for Cramping and Spasms
Peppermint oil works by relaxing the smooth muscle lining your digestive tract, likely by blocking calcium channels that trigger intestinal contractions. This makes it particularly useful when your upset stomach involves cramping, bloating, or that tight, churning feeling in your abdomen. Peppermint tea is the easiest way to get this benefit, though enteric-coated peppermint oil capsules deliver a more concentrated dose directly to the gut.
One caveat: peppermint can relax the valve between your stomach and esophagus, which may worsen heartburn. If acid reflux is part of what’s bothering you, skip the peppermint and try ginger instead. Ginger tea or ginger chews have a long track record for easing nausea, and they won’t aggravate reflux the way peppermint can.
A Heating Pad Can Help More Than You’d Expect
Placing a heating pad or warm compress on your abdomen does more than just feel comforting. Heat therapy causes blood vessels to widen, increasing blood flow to the area. That extra circulation helps flush out inflammatory compounds and pain-signaling molecules while delivering oxygen and nutrients. Heat also directly relaxes muscle tension, which can reduce spasms in the abdominal wall and the digestive muscles beneath it.
Keep the temperature comfortable, not hot enough to redden your skin. About 15 to 20 minutes at a time is a reasonable window. A warm (not hot) bath offers similar benefits if you don’t have a heating pad handy.
Over-the-Counter Options
Which product to reach for depends on your symptoms.
- Antacids (calcium carbonate products like Tums) neutralize stomach acid quickly, making them a good pick for heartburn or that sour, burning feeling. They work within minutes but wear off relatively fast.
- H2 blockers (like famotidine) take about an hour to kick in but reduce acid production for four to ten hours. These are better when you need longer-lasting relief or expect symptoms to persist through the night.
- Bismuth subsalicylate (Pepto-Bismol) is the most versatile option for general stomach upset. It reduces fluid flow into the bowel, calms intestinal inflammation, and can even target some of the bacteria responsible for diarrhea. It’s useful for nausea, indigestion, and loose stools all at once.
Follow the dosing instructions on the package for any of these. Bismuth subsalicylate contains a compound related to aspirin, so it’s not appropriate for children or anyone who needs to avoid aspirin-type medications.
The Role of Probiotics
Probiotics get a lot of attention for gut health, but the evidence for acute stomach upset is mixed. One meta-analysis found that a well-studied probiotic strain shortened diarrhea episodes in children by about two days compared to placebo. However, a larger trial of 646 children with acute watery diarrhea found no significant difference in stool frequency, diarrhea duration, or vomiting between the probiotic group and the control group.
Probiotics are unlikely to hurt, and they may help some people recover faster. But they’re not a reliable fix for an upset stomach that’s happening right now. If you already take a daily probiotic, keep taking it. If you don’t, a single dose during a stomach bug probably won’t change much. Yogurt with live cultures is a reasonable food choice during recovery, since it provides both probiotics and easy-to-digest nutrition.
Red Flags That Need Medical Attention
Most upset stomachs are minor and self-limiting, but certain patterns signal something more serious. Seek emergency care if you’re experiencing severe abdominal pain along with any of these:
- Vomiting that won’t stop, or inability to keep any liquids down
- Complete inability to have a bowel movement combined with worsening pain
- Pain that feels similar to a previous episode but is noticeably more severe or different in character
- A recent history of abdominal surgery
- Blood in your vomit or stool
- Signs of dehydration like dizziness, dark urine, or no urination for several hours
Stomach pain that steadily worsens over several hours, localizes to one specific spot (like the lower right side), or comes with a fever above 101°F also warrants prompt evaluation rather than continued home care.
