After you throw up, the most important things are to rest your stomach, protect your teeth, and start replacing lost fluids slowly. Jumping straight into drinking water or eating can trigger another round of vomiting, so timing matters. Here’s what to do in the minutes, hours, and days after vomiting to recover as quickly as possible.
Wait Before Drinking Anything
Your stomach needs a short break after vomiting. Wait at least 15 to 20 minutes before taking your first sip of anything. When you do start, go small: a tablespoon or two of water or an oral rehydration solution every 10 minutes. If that stays down, you can gradually increase the amount over the next hour or two.
If you drink too much too fast and vomit again, wait another 10 minutes and start over with even smaller sips. The goal is to keep tiny amounts down consistently rather than gulping a full glass and losing it all. Ice chips are a good option if even small sips feel like too much.
Rinse Your Mouth, but Don’t Brush Yet
Stomach acid coats your teeth when you vomit, and your first instinct is usually to grab a toothbrush. Resist that for at least 30 minutes. Brushing while acid is still on your enamel grinds it in and wears down the tooth surface. Instead, rinse your mouth with plain water right away, or swish with a mix of water and a teaspoon of baking soda to neutralize the acid. After 30 minutes, you can brush normally.
Rehydrate With the Right Fluids
Vomiting pulls water, sodium, and potassium out of your body quickly. Plain water replaces the fluid but not the electrolytes, so pairing it with an oral rehydration drink, diluted sports drinks, or clear broth makes a real difference in how fast you feel better. Pedialyte or similar electrolyte solutions work well for both adults and children.
Avoid anything carbonated, caffeinated, or high in sugar for the first several hours. Sodas and juice can irritate a sensitive stomach and actually pull more water into your gut, making things worse. Stick with room-temperature or slightly cool liquids, which tend to be easier to keep down than ice-cold drinks.
If Nausea Lingers, Try Ginger
Ginger is one of the most studied natural remedies for nausea, and it genuinely works for many people. Dividing about 1,000 to 1,500 milligrams of ginger into several smaller doses throughout the day is the range most research supports. In practical terms, that’s roughly a teaspoon of freshly grated ginger, a couple of small pieces of crystallized ginger, or up to four cups of ginger tea spread across the day.
Even just inhaling the scent of ginger (from fresh root or essential oil) has been shown to reduce nausea after surgery. If ginger isn’t your thing, peppermint tea is another gentle option. For over-the-counter relief, bismuth subsalicylate (the active ingredient in Pepto-Bismol) can help calm stomach flu-related nausea by protecting the stomach lining. Don’t give it to children under 12, and avoid it if you take blood thinners or are allergic to aspirin, since it’s in the same drug family.
Ease Back Into Eating
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s fine for a day or two, but there’s no clinical evidence that it works better than any other bland diet, and it’s nutritionally limited. A broader range of easy-to-digest foods will help you recover faster.
Once you’re keeping fluids down for a few hours, start with small portions of simple foods: plain crackers, oatmeal, boiled potatoes, or brothy soups. Pay attention to how your stomach responds. If those sit well, you can move on to more nutritious options like cooked carrots, sweet potatoes without skin, avocado, scrambled eggs, or plain chicken or fish. These provide the protein and nutrients your body needs to bounce back without being hard on your digestive system.
For the first day, avoid greasy, spicy, or heavily seasoned foods. Dairy can also be harder to tolerate right after vomiting. Eat slowly, chew thoroughly, and stop if nausea returns. Small meals every few hours are easier on your stomach than three large ones.
Rest and Monitor Your Body
Vomiting is physically exhausting. It strains your abdominal muscles, spikes your heart rate, and depletes your energy. Lying down on your side (not flat on your back, which can be a choking risk if you vomit again) and resting for at least a few hours gives your body time to settle. Prop your head up slightly if lying flat makes the nausea worse.
Avoid strong smells, bright screens, and unnecessary movement in the first hour or two. Motion and sensory stimulation can retrigger the vomiting reflex when your stomach is still irritable.
Signs That Need Medical Attention
A single episode of vomiting from a stomach bug, food that didn’t agree with you, or a hangover is usually something your body handles on its own within a day. But certain patterns signal something more serious:
- Duration: Vomiting that lasts more than two days in adults, more than 24 hours in children under 2, or more than 12 hours in infants.
- Dehydration signs: Excessive thirst, dry mouth, dark urine, urinating much less than usual, dizziness or lightheadedness when you stand up, or noticeable weakness.
- What’s in the vomit: Bright red blood, material that looks like coffee grounds (which indicates older blood), or green-colored vomit, which can suggest bile and a possible intestinal blockage.
- Recurring pattern: Bouts of nausea and vomiting that come and go for longer than a month point to a chronic issue worth investigating.
Dehydration is the most common complication of vomiting, especially in young children and older adults. If you can’t keep any fluids down for more than a few hours and you’re noticing the signs listed above, you may need IV fluids to catch up on what you’ve lost.
