The best thing to drink after throwing up is small sips of water or an oral rehydration solution, but not right away. Your stomach needs a short rest period of one to two hours before you introduce any fluids. Drinking too soon can irritate the stomach lining and trigger another round of vomiting, undoing any progress toward rehydration.
Wait Before You Drink Anything
The instinct after vomiting is to reach for a glass of water immediately. Fight that urge. Even if you feel better, your stomach is still in a reactive state, and putting anything into it too quickly can set off the whole cycle again. Give yourself a grace period of at least one to two hours with nothing by mouth. During this time, rest in a comfortable position, ideally sitting slightly upright or propped on pillows, since lying flat can keep nausea going.
Once that window has passed and you’re not actively feeling nauseated, start with very small amounts of fluid. The guideline used in clinical rehydration is about 5 milliliters (roughly one teaspoon) every one to two minutes. That pace feels almost pointlessly slow, but it works. Your stomach tolerates these tiny volumes without rebelling, and they add up over time. After 15 to 30 minutes of successful sipping, you can gradually increase to larger sips.
Best Drinks for Recovery
Plain water is always a safe starting point, but it doesn’t replace the sodium, potassium, and sugar your body lost during vomiting. For more effective rehydration, reach for one of these options:
- Oral rehydration solutions are the gold standard. Products like Pedialyte or store-brand equivalents contain a balanced ratio of glucose and sodium designed to maximize water absorption in your intestines. They work significantly better than water alone at restoring what you’ve lost.
- Clear broth (chicken, vegetable, or beef) provides sodium and a small amount of energy. Fat-free versions are easier on a sensitive stomach. Sip it warm, not hot.
- Sports drinks like Gatorade or Powerade offer electrolytes and are widely available. They contain more sugar than oral rehydration solutions, so diluting them with equal parts water can help if your stomach is still sensitive.
- Apple juice or white grape juice (no pulp) provides calories and fluid. These are best diluted with water, since full-strength fruit juice is high in sugar, which can pull water into your intestines and actually worsen diarrhea if that’s also a symptom.
- Flat ginger ale or ginger tea serves double duty. The active compounds in ginger (called gingerols) block receptors in the gut that trigger nausea signals to the brain. Freshly brewed ginger tea made from sliced ginger root is more effective than commercial ginger ale, which often contains very little real ginger. If you’re using ginger ale, let it go flat first, since carbonation can bloat an already irritated stomach.
- Peppermint tea is another option that can help settle nausea, served lukewarm and sipped slowly.
Plain tea and black coffee are technically on the clear liquid list, but caffeine can irritate the stomach lining and increase urine output, which works against rehydration. Save those for after you’ve fully recovered.
What Not to Drink
Full-sugar sodas are one of the worst choices, despite the old advice about flat cola settling your stomach. The high sugar concentration creates an osmotic effect in your intestines, meaning unabsorbed sugar draws water out of your body and into your bowel. This can cause watery diarrhea on top of vomiting, accelerating dehydration rather than reversing it.
Milk and dairy-based drinks are hard to digest when your stomach is already compromised. Alcohol is an obvious no, since it’s both a stomach irritant and a diuretic. Acidic drinks like orange juice and tomato juice can burn an already raw esophagus and trigger more nausea. Energy drinks combine high sugar, caffeine, and carbonation into a triple threat your stomach doesn’t need.
How to Tell If You’re Getting Dehydrated
Vomiting once or twice from a stomach bug or food poisoning is unpleasant but usually manageable at home. The real danger is dehydration, which develops when you can’t keep enough fluids down to replace what you’ve lost. Early signs include increased thirst, a dry or sticky mouth, darker urine, and noticeably less urine than normal. A body weight drop of 2% or more (about 3 pounds for a 150-pound person) indicates dehydration is setting in.
If dehydration progresses, you may notice dizziness when standing up, muscle weakness, a rapid heartbeat, or confusion. These are signs that your body’s fluid volume is dropping to a level where your circulation is affected. At this point, oral rehydration at home may not be enough, and intravenous fluids become necessary to restore balance quickly. Seek medical attention if you can’t keep any fluids down for more than 12 hours, if you notice the more severe symptoms listed above, or if vomiting is accompanied by high fever, severe abdominal pain, or blood.
Rehydrating Children After Vomiting
Kids dehydrate faster than adults because of their smaller body size, so the stakes are higher. The same teaspoon-every-one-to-two-minutes approach works well, though it requires patience and a dedicated caregiver sitting bedside. A pediatric oral rehydration solution like Pedialyte is the best choice for children. It’s specifically formulated for smaller bodies and comes in freezer pops and flavored versions that kids are more willing to take.
For breastfed infants, continue nursing in short, frequent sessions once the vomiting has paused. Breast milk is well-tolerated and provides both fluid and electrolytes. Formula-fed babies can return to their usual formula in small volumes. Avoid giving young children fruit juice, sports drinks, or soda as their primary rehydration fluid, since the sugar content is too high relative to their body weight and can worsen symptoms.
When You’re Ready to Eat Again
Once you’ve kept fluids down for several hours, your body will start signaling hunger. Start with bland, easy-to-digest foods: plain crackers, dry toast, white rice, or a small portion of banana. These foods provide calories and are gentle on a recovering stomach. Eat small amounts and wait 30 minutes to see how your stomach responds before eating more.
Avoid fatty, spicy, or heavily seasoned foods for at least 24 hours after your last episode of vomiting. Greasy foods slow stomach emptying, which can bring nausea right back. Dairy products are best reintroduced last, since the enzymes needed to digest lactose are temporarily reduced after a bout of gastrointestinal illness. Most people can return to their normal diet within 24 to 48 hours.
