Most stomach upset passes on its own within a few hours, and a combination of simple strategies can speed things along. Whether you’re dealing with nausea, bloating, cramping, or general queasiness after eating, the goal is the same: calm the muscles in your digestive tract, replace lost fluids, and avoid anything that makes the irritation worse.
Start With Small Sips, Not Big Meals
When your stomach is unhappy, the single most helpful thing you can do is stay hydrated without overwhelming your gut. Take small, frequent sips of water or a clear fluid rather than gulping a full glass. If you’ve been vomiting or having diarrhea, your body loses both water and electrolytes. A simple homemade rehydration drink (water with a pinch of salt and a small amount of sugar) works because glucose helps your small intestine absorb sodium and water in a 1:1 ratio, pulling fluid back into your system more efficiently than water alone.
Avoid alcohol, coffee, and carbonated drinks while your stomach is actively upset. These can increase acid production or introduce gas that makes bloating worse. Room-temperature or slightly warm liquids tend to be easier to tolerate than ice-cold ones.
Try Peppermint for Cramps and Bloating
Peppermint is one of the best-studied natural options for calming digestive spasms. It works by reducing calcium flow into the smooth muscle cells lining your gut, which relaxes those muscles and eases cramping. This is the same basic mechanism used by some prescription medications for gut spasms, just in a milder, plant-based form.
Peppermint tea is the gentlest way to try this. If you deal with stomach cramps regularly, enteric-coated peppermint oil capsules have stronger clinical support. In one trial of 110 people with irritable bowel syndrome, 79% of those taking peppermint oil capsules before meals experienced less severe symptoms, 56% became pain-free, and 79% reported less bloating over the course of a month. One note: peppermint can worsen heartburn or acid reflux because it relaxes the valve between your esophagus and stomach. If reflux is part of your problem, skip the peppermint and try ginger instead.
Use Pressure on Your Inner Wrist
If nausea is your main symptom, acupressure on the inside of your wrist can help. The point, known as P6, sits about three finger-widths below your wrist crease, between the two tendons on your inner forearm. Press firmly with your thumb for one to two minutes, then switch wrists.
This isn’t just folk wisdom. A Cochrane review pooling data from over 5,000 participants found that stimulating this point reduced nausea by about 32% and vomiting by 40% compared to sham treatment. The effect was roughly comparable to standard anti-nausea medications. It’s free, has no side effects, and you can do it anywhere.
Eat Bland Foods, but Don’t Starve Yourself
You may have heard of the BRAT diet (bananas, rice, applesauce, toast) as the classic recommendation for an upset stomach. It’s fine as a starting point for the first day when you feel your worst, but sticking to it for more than 24 hours can actually slow recovery. The American Academy of Pediatrics no longer recommends it for children because it lacks protein, calcium, vitamin B12, and fiber, all of which your gut needs to heal. The same applies to adults.
A better approach: eat bland, soft foods as tolerated, and expand your diet as soon as you can. Good options beyond the BRAT staples include plain crackers, boiled potatoes, broth-based soups, scrambled eggs, and steamed vegetables. Avoid greasy, spicy, or heavily seasoned foods until your stomach has fully calmed down. Eating smaller portions more frequently puts less strain on your digestive system than sitting down to a large meal.
Over-the-Counter Options That Help
For nausea, diarrhea, or general stomach discomfort, bismuth subsalicylate (the active ingredient in Pepto-Bismol) coats the stomach lining and can reduce irritation. The standard adult dose is two tablets or two tablespoons every 30 minutes to an hour as needed, up to 16 doses in 24 hours. Don’t use it if you’re allergic to aspirin, since the two compounds are chemically related.
For bloating and gas, simethicone (found in Gas-X) breaks up gas bubbles in your digestive tract. It doesn’t get absorbed into your bloodstream, so side effects are minimal. For heartburn or acid-driven stomach pain, an antacid can neutralize stomach acid quickly, while H2 blockers like famotidine last longer. Choose based on whether you need fast but short relief or something that will carry you through several hours.
Simple Habits That Help Your Stomach Recover
Lying flat can push stomach acid toward your esophagus, especially after eating. If you need to rest, prop yourself up at a slight angle or lie on your left side, which positions your stomach below your esophagus and can reduce reflux. Loose clothing also helps. Tight waistbands put pressure on your abdomen and can worsen bloating and nausea.
Gentle movement, like a slow walk around the block, can stimulate digestion and relieve gas. This is especially useful for bloating after a big meal. Avoid intense exercise, though, since it diverts blood flow away from your digestive system and can make nausea worse.
Heat can relax tense abdominal muscles and ease cramping. A warm (not hot) heating pad or hot water bottle placed on your stomach for 15 to 20 minutes often provides noticeable relief, particularly for menstrual-related stomach discomfort or stress-induced cramps.
When Stomach Trouble Needs Medical Attention
Most stomach upset resolves within a day or two. But certain symptoms signal something more serious. Seek immediate care if you notice blood in your vomit or stool (including black, tarry stools), if you can’t keep any liquids down, or if you feel lightheaded or dizzy. These can indicate internal bleeding or dangerous dehydration.
Pain that starts near your belly button and moves to your lower right side, especially if it worsens when you move, cough, or take deep breaths, may point to appendicitis. Upper abdominal pain that gets worse after eating and comes with fever or a rapid pulse could indicate pancreatitis. Both require prompt evaluation.
If you’ve had prior abdominal surgery and develop severe pain with constipation or inability to pass gas, a bowel obstruction may be the cause. And if your stomach symptoms persist for a week or longer without improvement, or if they seem connected to a medication you’re taking (particularly aspirin or other pain relievers), that’s worth a conversation with your doctor rather than continued self-treatment.
