After vomiting, the priority is replacing lost fluids and electrolytes before worrying about food. Wait at least 30 to 60 minutes after your last episode of vomiting before sipping anything, then start with very small amounts of clear liquids. Trying to drink or eat too quickly is the most common mistake, and it usually triggers more vomiting.
Start With Small Sips, Not Full Glasses
Your stomach needs time to settle. Once you’ve gone 30 to 60 minutes without vomiting, begin with just 1 to 2 tablespoons of clear liquid every 20 minutes. That feels painfully slow when you’re thirsty, but flooding an irritated stomach with a full glass of water almost guarantees it comes back up. If you keep those small sips down for a couple of hours, gradually increase the amount.
The best first options are water, ice chips, clear broth, diluted apple juice, or an oral rehydration solution. Oral rehydration solutions are specifically designed for this situation. They contain about three times more sodium than sports drinks (roughly 60 millimoles per liter versus 18), which makes a real difference in how well your intestines absorb the fluid. Sports drinks like Gatorade are better than plain water but not as effective as a proper rehydration solution, and their higher sugar content can sometimes worsen nausea. If you don’t have a rehydration solution on hand and can’t get to a store, alternate between water and broth to get both fluid and some sodium.
Which Electrolytes You’re Losing
Vomiting drains more than just water. Gastric fluid is rich in chloride, potassium, and sodium, and losing enough of it throws off your body’s electrolyte balance. Low potassium is especially common after repeated vomiting, which is why bananas, diluted fruit juice, and broth are frequently recommended during recovery. They’re not just gentle on the stomach; they’re actively replacing what you lost. Coconut water is another reasonable source of potassium if you tolerate it.
Ginger Can Help You Keep Things Down
If nausea keeps coming in waves and makes it hard to sip fluids, ginger is one of the most studied natural remedies for settling the stomach. Clinical trials consistently show that roughly 1,000 milligrams of ginger per day reduces nausea, with doses between 500 mg and 1,000 mg showing the strongest effect. That translates to about a half-inch piece of fresh ginger steeped in hot water, or a couple of ginger chews or capsules from a pharmacy. Flat ginger ale, despite its reputation, contains very little actual ginger and a lot of sugar, so it’s not a great substitute.
What to Eat First
Don’t rush into food. Most people do best waiting until they can keep fluids down consistently for several hours before trying anything solid. When you’re ready, start with small portions of bland, low-fat foods that are easy to digest.
Good first foods include:
- Plain white rice or white toast (refined carbohydrates are gentle on the stomach)
- Bananas (soft, easy to digest, and a good source of potassium)
- Applesauce (low fiber, unlikely to irritate)
- Plain crackers or graham crackers
- Broth-based soup (delivers fluid, sodium, and a small amount of calories)
- Boiled or baked potatoes (no butter or cream)
- Eggs (scrambled or soft-boiled, without added fat)
- Gelatin or popsicles (also count toward fluid intake)
You may have heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a fine starting point for the first day or two, but there’s no research showing it’s better than other bland foods. Harvard Health notes that restricting yourself to only those four items isn’t necessary. Once your stomach tolerates them, expand to other easy-to-digest options like cooked carrots, skinless chicken, whitefish, sweet potatoes without the skin, or avocado.
Foods and Drinks to Avoid
Certain foods are likely to trigger more nausea or slow your recovery. Your digestive system is temporarily more sensitive than usual, and some of these effects can linger for weeks.
Skip these until you feel fully recovered:
- High-fat or fried foods (fat slows stomach emptying, which prolongs nausea)
- Dairy products (many people temporarily lose the ability to digest lactose after a stomach illness, sometimes for a month or more)
- Caffeine (coffee, tea, and colas can irritate the stomach lining and act as mild diuretics, worsening dehydration)
- Sugary drinks and fruit juices at full strength (high concentrations of simple sugar can pull water into the intestines and make diarrhea worse)
- Spicy foods
- Alcohol (a diuretic that will dehydrate you further)
- Raw vegetables and high-fiber foods (harder to break down when your gut is inflamed)
The dairy point surprises a lot of people. Even if you’re normally fine with milk and cheese, a bout of gastroenteritis can temporarily damage the cells in your intestines that produce the enzyme needed to break down lactose. If dairy seems to cause bloating or diarrhea in the days after your illness, that’s why.
A Realistic Recovery Timeline
For most people, the first 6 to 12 hours are fluids only. By 12 to 24 hours, if vomiting has stopped, you can introduce bland solids in small portions. Over the next two to three days, gradually return to your normal diet, adding back foods one at a time so you can identify anything that doesn’t sit well. Eating five or six small meals rather than three large ones puts less strain on your stomach during this period.
Your appetite will likely be poor for a few days, and that’s normal. Focus on staying hydrated rather than forcing yourself to eat full meals. Even small amounts of food are fine as long as you’re replacing fluids.
Signs You Need More Than Food and Fluids
Oral rehydration works for mild to moderate dehydration, but severe dehydration requires medical treatment. Watch for these warning signs: dark-colored urine or urinating much less than usual, dizziness or confusion, extreme thirst that doesn’t improve with sipping fluids, sunken eyes, or skin that stays tented when you pinch it instead of flattening back immediately. If you can’t keep any fluids down at all for more than 24 hours, or if you develop a fever above 102°F, those are reasons to seek medical care. Children and older adults dehydrate faster and should be monitored more closely. For infants, no wet diapers for three hours or a rapid heart rate are especially concerning signs.
