After throwing up, your first priority is replacing lost fluids, not food. Wait until the vomiting has stopped for at least a few hours before taking small sips of water or an oral rehydration solution. Eating too soon or drinking too much at once can trigger another round of nausea, so recovery works best in stages: clear liquids first, then bland foods, then a gradual return to your normal diet.
Start With Small Sips, Not Full Glasses
Your stomach is irritated and possibly still contracting after vomiting, so flooding it with liquid will often backfire. Begin with a few small sips of water every 10 to 15 minutes. If that stays down for 30 minutes to an hour, you can gradually increase the amount. Ice chips or frozen popsicles made from clear liquids work well if even sips feel like too much.
Plain water replaces volume, but vomiting also strips your body of sodium, potassium, and other electrolytes. An oral rehydration solution is the most effective way to replace what you’ve lost. These products contain a balanced ratio of sodium and a small amount of sugar that helps your intestines absorb fluid faster. Sports drinks are a common substitute, but they typically contain too much sugar and too little sodium for proper rehydration, which can actually worsen diarrhea if you have a stomach bug. Diluting a sports drink with equal parts water is a reasonable compromise if you don’t have a rehydration solution on hand.
Avoid caffeinated drinks, alcohol, acidic juices like orange juice, and anything carbonated during the first several hours. These can all irritate your stomach lining or pull water out of your system through increased urination.
When to Start Eating Again
A good rule of thumb is to wait about eight hours after your last episode of vomiting before introducing solid food. Some people feel ready sooner, and that’s fine as long as liquids are staying down comfortably. The key signal is that you can drink without nausea returning. If sipping water still makes you queasy, your stomach isn’t ready for food yet.
When you do start eating, keep portions small. A few bites of a cracker or half a banana is a better first meal than a full plate. Your stomach has been through a lot of muscular contractions, and its lining may still be inflamed. Small amounts let you test the waters without overwhelming your digestive system.
Best Foods for a Recovering Stomach
Bland foods that require minimal digestion are your best options in the first day or two. They put less demand on your stomach lining and intestines. The classic BRAT diet (bananas, rice, applesauce, toast) is a fine starting point, but you don’t need to limit yourself to just those four items. According to Harvard Health, brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereals are equally easy to digest and offer more variety.
Once your stomach has settled, typically after a day or two of bland eating, you can start adding more nutritious foods back in. Good next steps include:
- Cooked squash like butternut or pumpkin
- Cooked carrots
- Sweet potatoes without the skin
- Avocado
- Skinless chicken or turkey
- Fish
- Eggs
These are all still mild on the stomach but provide the protein and nutrients your body needs to recover. Staying on the BRAT diet for more than a couple of days can actually slow recovery because it’s low in protein, fat, and several vitamins.
Foods and Drinks to Avoid
Certain categories of food are significantly harder for an irritated stomach to process. Steer clear of these until you’re fully back to normal:
- Dairy products: Milk, cheese, and ice cream can be difficult to digest when your gut is compromised, especially if a stomach virus has temporarily reduced your ability to break down lactose.
- Fried or greasy foods: Fat slows stomach emptying, which can extend nausea and bloating.
- Spicy foods: These directly irritate an already inflamed stomach lining.
- Acidic foods: Citrus fruits, tomatoes, and vinegar-based sauces can sting damaged tissue in your esophagus and stomach.
- Sugary foods and drinks: High sugar concentrations can draw water into the intestines, potentially causing diarrhea and worsening dehydration.
- Alcohol and caffeine: Both increase fluid loss and irritate the stomach.
Ginger for Lingering Nausea
If nausea hangs around even after the vomiting stops, ginger is one of the most studied natural remedies. Clinical trials have used dosages ranging from 250 mg to 1 g per day, typically split into several smaller doses. You don’t need to measure that precisely at home. A cup of ginger tea made from fresh sliced ginger, or a few ginger chews, falls within that range and can meaningfully reduce nausea. Even smelling ginger essential oil has shown benefits. A large trial of over 1,100 patients found that inhaling ginger aromatherapy significantly reduced nausea and the need for anti-nausea medication.
One caveat: large amounts of ginger can cause heartburn or mild stomach irritation on their own. Start with a small cup of tea and see how it sits before having more.
Rehydrating Children After Vomiting
Children, especially infants and toddlers, dehydrate faster than adults and need closer attention. For kids under 22 pounds (10 kg), offer 2 to 4 ounces of an oral rehydration solution after each vomiting episode. For larger children, 4 to 8 ounces per episode is appropriate. Give it in small, frequent sips rather than all at once.
The same food timeline applies: no solids for about eight hours after vomiting starts, then bland foods in small amounts. Avoid giving children fruit juice, soda, or other sugary clear liquids as a rehydration strategy. These drinks contain excess sugar and inadequate sodium, which can cause further diarrhea and electrolyte imbalances.
Watch for signs that dehydration is getting ahead of you. Dry mouth, no tears when crying, dark urine, fewer wet diapers than usual, and unusual sleepiness or irritability all suggest a child needs medical evaluation. Vomiting that lasts more than 24 hours in children under two, or more than 12 hours in infants, also warrants a call to your pediatrician.
Warning Signs That Need Medical Attention
Most vomiting resolves on its own within a day or two. But certain symptoms alongside vomiting point to something more serious. Get to urgent care or an emergency room if your vomit contains blood, looks like coffee grounds, or is green. These can signal internal bleeding or a bowel obstruction.
Other red flags include severe abdominal pain or cramping, chest pain, confusion, blurred vision, high fever with a stiff neck, or signs of significant dehydration like dizziness when standing, dark urine, and excessive thirst. For adults, vomiting that continues beyond two days is the general threshold for scheduling a medical appointment even without other alarming symptoms.
