When you’re throwing up, your first priority isn’t food. It’s fluid. Vomiting drains water and electrolytes fast, and replacing them matters more than eating anything solid. Once the vomiting slows down, you can start with small sips of clear liquids and gradually work your way back to gentle, bland foods over the next day or two.
Start With Small Sips, Not Meals
After your last vomiting episode, give your stomach a short rest. You don’t need to wait a set number of hours, but jumping straight into a full glass of water often triggers another round of nausea. Instead, take tiny sips of clear fluids every few minutes. If those stay down for 15 to 20 minutes, gradually increase the amount.
Good options for this first phase include plain water (flat or lightly carbonated), clear broth or bouillon, an oral rehydration solution like Pedialyte, diluted apple juice, sports drinks, popsicles, and weak tea. These provide electrolytes like sodium and potassium without irritating your stomach. Avoid anything with milk, cream, or pulp during this stage.
If even small sips come back up repeatedly, try sucking on ice chips instead. The slower absorption can help your stomach tolerate the fluid.
Why Rehydration Matters So Much
Every time you vomit, you lose water, sodium, and potassium. Oral rehydration solutions work because your gut absorbs water most efficiently when sodium and glucose arrive together in roughly equal amounts. That’s the science behind products like Pedialyte and the WHO’s rehydration formula, which uses a 1:1 sodium-to-glucose ratio. Commercial rehydration drinks use closer to a 1:3 ratio, which still works well.
You can spot dehydration by watching for dark yellow urine, a dry mouth, urinating much less than usual, a rapid heartbeat, or skin that doesn’t snap back quickly when you pinch the back of your hand. If you notice several of these signs, especially if you can’t keep any fluids down for more than a few hours, you likely need medical attention for IV fluids.
When to Try Solid Food
There’s no magic waiting period. The National Institute of Diabetes and Digestive and Kidney Diseases recommends returning to your normal diet as soon as your appetite comes back, even if you still have some diarrhea. For most people, that means a few hours after the vomiting stops, sometimes longer. Let your body guide you. If the thought of food still makes you queasy, stick with liquids a while longer.
Best Foods to Eat First
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. These are fine for a day or two, but there’s no clinical evidence that restricting yourself to only those four foods helps you recover faster. A broader selection of bland, easy-to-digest foods gives your body more of the protein and nutrients it needs to bounce back.
Good choices include:
- Starches: white rice, plain crackers, boiled potatoes (no skin), refined pasta, cream of wheat
- Proteins: scrambled eggs, plain baked chicken, white fish (steamed or baked), tofu, creamy peanut butter in small amounts
- Fruits: bananas, applesauce, canned fruit without skins, melon
- Other: broth-based soup, plain gelatin, graham crackers, vanilla wafers, pudding made with low-fat milk
Start with small portions. A few bites of toast or half a banana is plenty for your first attempt. If that stays down comfortably, eat a little more at your next meal. Most people can return to their full normal diet within one to three days.
Foods and Drinks to Avoid
Certain foods are harder for a recovering stomach to process. Fat is the biggest culprit: it naturally slows stomach emptying, which can make nausea worse. Skip fried foods, greasy meats like bacon and sausage, full-fat dairy, and rich sauces until you feel solidly better.
High-fiber foods are also tough right now. Raw vegetables, whole grains, beans, dried fruit, and anything with tough skins or seeds sit in your stomach longer and can aggravate nausea. Broccoli, cabbage, Brussels sprouts, and onions are particularly common offenders. Spicy food and highly acidic foods like citrus and tomato can irritate an already sensitive stomach lining.
For drinks, skip coffee (which can increase stomach acid), alcohol, and sugary sodas. The high sugar concentration in regular soda can actually pull water into your intestines and make dehydration worse.
Ginger Can Help With Nausea
Ginger is one of the few natural remedies with solid evidence behind it. Studies in pregnant women (who experience some of the most persistent nausea) found that about 1,000 mg of ginger per day, typically split into four doses, reduced vomiting episodes by roughly 50% compared to a placebo. In one trial, vomiting resolved completely in 67% of people taking ginger by day six.
You can get ginger through capsules, ginger tea, or even flat ginger ale made with real ginger (check the ingredients; many commercial ginger ales use artificial flavoring). Ginger chews and candies are another option when you can’t stomach much else.
Rehydrating Kids After Vomiting
Children dehydrate faster than adults because of their smaller body size, so the sipping strategy matters even more. Nationwide Children’s Hospital recommends a phased approach: start by offering a very small amount of fluid every five minutes, repeating four times. If the child keeps it down, double the amount and repeat.
The specific volumes depend on age. For babies 6 to 12 months, start with just 5 mL (about one teaspoon) every five minutes. For toddlers 1 to 3 years, start with 10 mL (two teaspoons). Kids older than 3 can handle 15 mL (one tablespoon) to start. Once they tolerate the smaller amount four times in a row, you can double it.
An oral rehydration solution is the best fluid choice for young children. Avoid giving kids fruit juice at full strength or sports drinks designed for adults, as the sugar content is too high for small bodies. Once they’re keeping fluids down, offer whatever foods they normally eat as soon as they show interest. There’s no benefit to withholding food from a hungry child who has stopped vomiting.
Signs Your Vomiting Needs Medical Attention
Most vomiting from stomach bugs or food poisoning resolves on its own within 24 to 48 hours. But some patterns signal something more serious. Watch for vomiting that contains blood or looks like coffee grounds, an inability to keep any fluids down for more than 12 hours (or 6 to 8 hours for young children), severe abdominal pain that isn’t just cramping, a fever above 104°F, or signs of significant dehydration like no urination for 8 or more hours, sunken eyes, or a rapid heartbeat at rest. In infants, no wet diapers for three hours and no tears when crying are reliable warning signs that dehydration has become serious.
