After throwing up, wait at least 1 to 2 hours before trying anything at all, and start with small sips of water rather than food. Solid food should wait until you’ve kept liquids down for a few hours, which means most people are looking at roughly 4 to 6 hours before eating their first bite of something bland. Rushing food too soon often triggers another round of vomiting because your stomach is still irritated and contracting.
Why Your Stomach Needs a Break
Vomiting is a violent process. Your abdominal muscles contract forcefully, stomach acid surges upward, and the lining of your stomach and esophagus takes a beating. After all that, your digestive system needs time to calm down before it can process anything new. The muscles that normally push food downward through your gut are still unsettled, and introducing food too quickly can restart the cycle.
There’s also a practical reason to wait: if you’re still nauseated, anything you eat is likely to come right back up, which means you lose both the food and whatever fluid came with it. That makes dehydration worse, not better.
Start With Fluids, Not Food
Your first priority after vomiting is replacing lost fluid. Begin with ice chips or very small sips of water, about every 15 minutes. If even that feels like too much, try sucking on a single ice chip at a time. The goal during the first hour or two is simply to prove your stomach can hold something down.
If you’re still vomiting, even smaller volumes can work. Research on rehydration shows that taking just one teaspoon (5 mL) of fluid every 5 minutes, then gradually increasing the amount, is enough for most people to rehydrate successfully, even if they’re still experiencing some nausea.
Once plain water is staying down reliably, you can move to other clear liquids:
- Clear broth
- Diluted electrolyte drinks
- Ice pops
- Gelatin
Stick with these for a few hours before attempting solid food.
When to Try Solid Food
Once you’ve kept liquids down for a few hours and your appetite starts returning on its own, that’s your signal to try eating. Don’t force it. If the thought of food still makes you queasy, your body is telling you it’s not ready.
Start small and bland. Good first foods include applesauce, bananas, plain crackers, dry toast, and plain oatmeal. These are easy to digest and unlikely to irritate your stomach further. You don’t need to limit yourself strictly to those options, though. Brothy soups, boiled potatoes, and unsweetened dry cereal are equally gentle choices.
The old advice to follow the BRAT diet (bananas, rice, applesauce, toast) is fine for a day or two, but nutrition experts now recommend broadening your choices sooner. Those four foods don’t provide much protein or many vitamins, and your body needs nutrients to recover. Once your stomach has settled, adding cooked carrots, sweet potatoes, skinless chicken, fish, eggs, or avocado gives you the protein and energy you need without being hard to digest.
Foods and Drinks to Avoid
Certain foods are more likely to trigger nausea or slow your recovery. For at least 24 to 48 hours after vomiting, steer clear of:
- Caffeine: coffee, tea, and caffeinated soft drinks can irritate your stomach lining and increase acid production.
- High-fat foods: fried foods, pizza, and fast food take longer to digest and can worsen nausea.
- Sugary drinks: sweetened beverages and fruit juices with high sugar content can pull water into your intestines and make diarrhea worse.
- Dairy: milk, cheese, and ice cream contain lactose, which many people have trouble digesting for up to a month after a stomach illness.
- Alcohol: it’s dehydrating and irritating to an already inflamed stomach.
Spicy and heavily seasoned foods are also best saved for when you’re feeling fully recovered.
Timeline for Children
Kids follow the same general pattern, but the stakes are higher because they dehydrate faster. For a child who has been vomiting, offer small amounts of an oral rehydration solution by spoon or syringe every minute or two. Don’t wait for them to ask for a drink, especially with younger children who may not recognize or communicate thirst.
Once a child is rehydrated and keeping fluids down, you can reintroduce their normal diet within 4 to 6 hours. There’s no need to restrict them to clear liquids for a full day. In fact, getting back to age-appropriate food relatively quickly helps with recovery.
Watch for signs of dehydration in kids more carefully than you would in adults. A dry tongue and lips, no tears when crying, sunken eyes, or going 8 hours without urinating (in toddlers) or having fewer than 6 wet diapers in a day (in infants) all signal that fluid loss is outpacing what you’re replacing.
Signs That Vomiting Needs Medical Attention
Most vomiting from a stomach bug or food poisoning resolves on its own within 12 to 24 hours. But some situations call for more than home care. Seek medical attention if you can’t keep any fluids down for more than 12 hours, if your urine is very dark or you haven’t urinated in 8 or more hours, or if you notice dry, wrinkled skin that doesn’t bounce back when pinched. Vomit that contains blood or looks like coffee grounds, severe abdominal pain, or a high fever alongside vomiting are also reasons to get help promptly.
