How to Relieve an Upset Stomach: Remedies That Work

Most upset stomachs resolve on their own within a few hours, but you don’t have to wait it out. A combination of simple home remedies, smart food choices, and the right over-the-counter option can cut your discomfort short. What works best depends on whether you’re dealing with nausea, cramping, bloating, or acid-related pain.

Start With What You Sip

When your stomach is off, what you drink matters more than what you eat. Small, frequent sips of clear fluids keep you hydrated without overwhelming your gut. Water is fine for mild discomfort, but if you’ve been vomiting or have diarrhea, plain water doesn’t replace the sodium and potassium you’re losing. An oral rehydration solution works better because it pairs glucose with sodium in a ratio that maximizes absorption through the intestinal wall. The WHO formula uses equal parts sodium and glucose at 75 milliequivalents per liter each. Premixed versions from the pharmacy use a slightly different ratio (roughly 1:3 sodium to glucose) but still work well.

If you don’t have a rehydration solution on hand, diluted broth or coconut water are reasonable stand-ins. Avoid full-strength fruit juice, soda, and coffee. Sugar-heavy drinks can pull water into the intestine and make diarrhea worse, while caffeine stimulates acid production in an already irritated stomach.

Apply Heat to Your Abdomen

A heating pad or hot water bottle on your stomach isn’t just comforting. Research from University College London found that heat above 40°C (104°F) activates specific receptors in the skin that block pain signals from damaged tissue underneath. These heat receptors essentially shut down the chemical messengers that transmit internal pain, which is why a warm compress can ease cramping, bloating, and that dull ache in your midsection surprisingly well.

Place the heat source over the area that hurts, with a thin cloth between the pad and your skin. Twenty minutes on, twenty minutes off is a safe rhythm that prevents skin irritation while keeping relief going.

Peppermint for Cramping and Bloating

Peppermint relaxes the smooth muscle lining your digestive tract, likely by blocking calcium channels that trigger muscle contractions. This makes it particularly useful when your stomach feels tight, gassy, or crampy. Peppermint tea is the gentlest option: steep fresh or dried leaves for five to ten minutes and sip slowly.

One caution: if your upset stomach involves acid reflux or heartburn, peppermint can make it worse. The same muscle-relaxing effect that eases cramping also loosens the valve between your esophagus and stomach, letting acid travel upward. Stick to ginger tea instead if burning or reflux is part of the picture. Ginger has a long track record for settling nausea specifically.

The Wrist Pressure Point for Nausea

If nausea is your main symptom, acupressure on a point called P6 is worth trying. You’ll find it on the inside of your forearm, about three finger-widths above your wrist crease, centered between the two tendons you can feel when you flex your wrist. Press firmly with your thumb for two to three minutes, then switch arms.

Clinical trials show that sustained pressure here reduces the frequency and severity of nausea, though researchers note the effect may partly overlap with placebo. Elastic wristbands with a built-in pressure nub (sold as “sea bands”) let you apply steady pressure hands-free. They’re inexpensive, drug-free, and safe for pregnant women dealing with morning sickness.

Over-the-Counter Options and How They Differ

Not all stomach medications do the same thing, so picking the right one matters.

  • Antacids (calcium carbonate): These neutralize stomach acid directly and work within minutes. They’re best for heartburn and acid-related discomfort. Relief is fast but short-lived, typically lasting one to two hours.
  • H2 blockers (famotidine): These reduce how much acid your stomach produces. They take about an hour to kick in but last four to ten hours, making them a better choice if your symptoms tend to drag on or flare at night.
  • Bismuth subsalicylate (Pepto-Bismol): This coats the stomach lining and targets nausea, indigestion, and diarrhea. Adults and children 12 and older can take one dose every half hour as needed for an upset stomach, up to eight doses in 24 hours. Children under 12 should not take it without a doctor’s guidance, and it’s off-limits for kids or teens recovering from flu or chickenpox due to the risk of a rare but serious condition called Reye’s syndrome.

If your upset stomach is tied to a specific dairy meal, lactase enzyme supplements can prevent the problem entirely. Take them just before eating foods that contain lactose. They supply the enzyme your body isn’t making enough of, breaking down milk sugar before it reaches the lower gut where it causes gas, bloating, and cramping.

What to Eat (and What to Skip)

You may have heard of the BRAT diet: bananas, rice, applesauce, and toast. It was a standard recommendation for decades, but the National Institute of Diabetes and Digestive and Kidney Diseases no longer advises following a restricted diet for acute stomach issues. In most cases, once you feel ready to eat again, you can return to your normal diet. Children should continue their usual age-appropriate meals, and infants should keep breastfeeding or drinking formula.

That said, “eat normally” doesn’t mean “eat anything.” While your stomach is still recovering, it makes sense to avoid the foods most likely to trigger another wave of discomfort: fried or greasy meals, spicy dishes, raw vegetables, alcohol, and anything highly acidic like tomato sauce or citrus. Small portions spread across the day are easier on your system than three large meals. Plain crackers, broth-based soup, steamed rice, and lean protein are all gentle starting points if you’re easing back in.

When an Upset Stomach Signals Something Serious

A garden-variety upset stomach is uncomfortable but not dangerous. Certain symptoms, however, suggest something beyond indigestion. Get to an emergency room if you experience any of the following alongside stomach pain:

  • Fever of 100.4°F or higher with abdominal discomfort
  • Blood in your vomit or stool, or stools that appear black and tarry
  • Severe, sudden pain that comes on without warning
  • Persistent pain in your lower right abdomen, which can indicate appendicitis
  • Chest pressure or shortness of breath paired with stomach pain
  • Bloating with an inability to pass gas or have a bowel movement, which may point to an obstruction
  • Inability to keep any fluids down, especially with ongoing vomiting or diarrhea

These combinations can signal appendicitis, internal bleeding, bowel obstruction, or other conditions that need immediate evaluation. Stomach pain accompanied by chest tightness is especially important to take seriously, as heart attacks can mimic digestive symptoms.
