Most upset stomachs resolve on their own within a day or two, and a combination of simple home remedies, the right foods, and short-term over-the-counter options can speed that process along. What works best depends on whether your main symptom is nausea, cramping, bloating, or diarrhea, so it helps to match the remedy to what you’re actually feeling.
Ginger for Nausea
Ginger is one of the most effective natural options for nausea. It works by enhancing movement through the digestive tract and blocking certain chemical signals in the gut and brain that trigger the urge to vomit. Clinical trials have used doses ranging from 250 mg to 1 g taken three to four times daily, and studies found no additional benefit from going above 1 g per day. You can get this from ginger capsules, ginger chews, or fresh ginger steeped in hot water for tea. Ginger ale is less reliable because most commercial brands contain very little actual ginger.
Peppermint for Cramping and Bloating
If your stomach trouble feels more like cramping or tightness, peppermint can help. It relaxes the smooth muscle lining the digestive tract, likely by blocking calcium channels that cause those muscles to contract. Peppermint tea is the gentlest way to try it. One important caveat: peppermint also relaxes the valve between your esophagus and stomach, which can worsen heartburn or acid reflux. If reflux is part of your problem, skip peppermint and try ginger instead.
Over-the-Counter Options
Pink bismuth liquid or tablets (the active ingredient in Pepto-Bismol) can help with nausea, diarrhea, and general stomach discomfort. It works by reducing fluid flow into the bowel, calming inflammation in the intestinal lining, and killing some of the bacteria that cause diarrhea. You may notice your tongue or stool turning dark or black while taking it. That’s harmless and goes away within a few days of stopping.
For heartburn or acid-related stomach pain, antacids that neutralize stomach acid provide fast relief. Liquid forms tend to work faster than tablets. Magnesium-based antacids like Maalox and Mylanta are particularly fast-acting. Calcium-based antacids like Tums are convenient but can sometimes cause rebound acid production if used frequently.
What to Eat (and What to Skip)
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s fine for the first day or two, but there’s no clinical evidence that restricting yourself to only those four foods helps you recover faster. A better approach is to eat bland, easy-to-digest foods more broadly. Brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereal all work well alongside the classic BRAT options.
Once your stomach starts to settle, adding nutrient-dense foods speeds recovery. Cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs are all gentle on the stomach while providing the protein and vitamins your body needs to bounce back. The goal is to move beyond ultra-bland eating as soon as you can tolerate it.
While you’re recovering, avoid fried or greasy foods, dairy, caffeine, alcohol, and heavily spiced dishes. These all increase acid production or are harder for an irritated gut to process.
Hydration Matters More Than Food
Dehydration is the most common complication of an upset stomach, especially if vomiting or diarrhea is involved. Small, frequent sips of water, clear broth, or an electrolyte drink are more important than eating in the first several hours. If plain water is hard to keep down, try sucking on ice chips or taking tiny sips every few minutes rather than drinking a full glass at once. Avoid sugary drinks and fruit juices, which can pull more water into the bowel and make diarrhea worse.
Acupressure at the Wrist
Pressing a point on the inner wrist known as PC6 (or Neiguan) has surprisingly strong evidence behind it. A large Cochrane review covering more than 5,000 participants found that stimulating this point reduced the incidence of nausea by about 32% and vomiting by about 40% compared to a sham treatment. You can find the point by placing three fingers across the inside of your wrist, starting at the crease. The spot just below your index finger, between the two tendons, is where you apply firm, steady pressure for two to three minutes. Inexpensive acupressure wristbands (often sold as motion sickness bands) press on this same point continuously.
How Long Recovery Takes
The timeline depends on what’s causing your symptoms. Food poisoning typically comes on fast, within two to six hours of eating contaminated food, and tends to resolve relatively quickly. Viral gastroenteritis (stomach flu) has a longer incubation period of 24 to 48 hours before symptoms start, and generally lasts about two days, though it can sometimes linger longer.
If your symptoms began shortly after a meal, food poisoning is more likely. If they crept in gradually and others around you are also sick, a virus is the more probable cause. Either way, most cases clear up within one to three days with supportive care at home.
Signs That Need Medical Attention
Most upset stomachs are uncomfortable but not dangerous. However, a few patterns warrant prompt medical care. Severe abdominal cramping that comes in waves can signal a bowel obstruction, especially if your abdomen is visibly distended and you’re unable to pass gas. Bloody vomit or stool, a fever that stays above 101.3°F, signs of dehydration (dark urine, dizziness, dry mouth, no urination for eight or more hours), and symptoms lasting beyond three days all justify a call to your doctor or a visit to urgent care.
