After throwing up, the most important thing you can do is pause, rest, and start replacing fluids slowly. Vomiting is usually your body’s way of clearing something harmful, and in most cases it resolves on its own within a day or two. What you do in the hours afterward determines how quickly you bounce back.
What to Do Right After Throwing Up
Resist the urge to drink a glass of water immediately. Your stomach is irritated, and gulping fluids too fast will likely trigger another round of vomiting. Start with ice chips or very small sips of water every 15 minutes. If that stays down, you can gradually increase the amount.
Rinse your mouth with water to clear the stomach acid, which can damage tooth enamel over time. Avoid brushing your teeth for at least 30 minutes, since scrubbing acid-softened enamel does more harm than good. Spit out the rinse water rather than swallowing it. If you’re still feeling waves of nausea, sit upright or lie on your side rather than flat on your back.
How to Rehydrate Without Getting Sick Again
Dehydration is the biggest practical risk from vomiting, especially if it continues for several hours. The key is starting small: about 5 milliliters (one teaspoon) every five minutes, then gradually increasing as your stomach tolerates it. This approach works even if you’re still vomiting occasionally, because your body absorbs some fluid between episodes.
Plain water works for mild cases, but if you’ve been throwing up repeatedly, you’re losing electrolytes (sodium, potassium, chloride) along with fluid. Oral rehydration solutions, diluted sports drinks, or clear broths help replace what’s lost. Avoid sugary sodas and fruit juices, which can pull more water into your intestines and make things worse.
Signs you’re becoming dehydrated include a dry mouth, dark yellow urine, and dry skin. In young children and infants, look for a dry tongue, sunken-looking eyes, and fewer wet diapers than usual. If you notice these signs and can’t keep any fluids down, that’s when the situation becomes more serious.
When and What to Eat
You may have heard of the BRAT diet (bananas, rice, applesauce, toast) as the go-to recovery plan. It’s no longer recommended as a strict protocol. The American Academy of Pediatrics considers it too restrictive, lacking the nutrients your gut needs to actually recover. Following it for more than 24 hours can slow healing rather than help it.
That said, the general principle behind it still makes sense: start with bland, easy-to-digest foods. Crackers, plain rice, broth-based soups, and bananas are all reasonable first choices. But as soon as you feel up to it, move back toward a normal diet. Your body needs protein, healthy fats, and a range of nutrients to rebuild. Avoid greasy, spicy, or heavily seasoned foods for the first day or so, along with caffeine and alcohol, which can irritate your stomach lining.
What Helps With Lingering Nausea
Ginger has genuine anti-nausea properties backed by clinical evidence. Studies on nausea during pregnancy found that 250 mg of powdered ginger taken four times a day (about 1,000 mg total) significantly reduced symptoms. You don’t need capsules to get the benefit. Ginger tea, ginger chews, or flat ginger ale with real ginger can all help settle your stomach.
Over-the-counter medications containing bismuth subsalicylate (the active ingredient in Pepto-Bismol) can calm an irritated stomach, though they work more on diarrhea and general stomach upset than on the vomiting reflex itself. For nausea that won’t quit, pharmacy antiemetics designed for motion sickness can sometimes help, but they tend to cause drowsiness.
Cool, fresh air and slow, deep breathing also reduce nausea. If you’re indoors, open a window or step outside briefly. Avoid strong smells, including cooking odors, perfume, and cleaning products, which can retrigger the vomiting reflex when your stomach is already on edge.
How Long Vomiting Typically Lasts
The timeline depends on the cause. Food poisoning tends to be intense but brief, often clearing within 12 to 24 hours as your body expels the offending bacteria or toxin. Viral gastroenteritis (the “stomach flu”) typically lasts about two days, though it can sometimes stretch longer. The virus usually has a 24 to 48 hour incubation period before symptoms even start, which is why you often can’t pinpoint exactly what made you sick.
If you’re still vomiting after 48 hours with no improvement, or if symptoms seem to be getting worse rather than better, that’s a signal to contact your doctor. For children under two, the threshold is shorter: 24 hours. For infants, it’s 12 hours.
Warning Signs That Need Immediate Attention
Most vomiting episodes are unpleasant but harmless. A few specific signs mean you should get to urgent care or an emergency room:
- Blood in your vomit, whether bright red or dark and resembling coffee grounds, which can indicate bleeding in your stomach or esophagus
- Green vomit, which may suggest a bowel obstruction
- Vomit that smells like fecal matter, another sign of possible obstruction
- High fever combined with a stiff neck, which can point to meningitis
- Signs of severe dehydration, particularly if you can’t keep any fluids down for several hours, feel dizzy when standing, or have not urinated in eight or more hours
Vomiting after a head injury also warrants immediate medical evaluation, as it can indicate a concussion or increased pressure inside the skull. The same goes for sudden, severe vomiting with intense abdominal pain, which could signal appendicitis, gallstones, or pancreatitis.
Preventing the Spread If It’s Contagious
Stomach viruses are extremely contagious, spreading through contaminated surfaces, shared utensils, and close contact. If you suspect a stomach bug, wash your hands thoroughly and often, especially after vomiting or using the bathroom. Norovirus, the most common culprit, can survive on surfaces for days and isn’t reliably killed by alcohol-based hand sanitizers. Soap and water is more effective.
Clean any surfaces that may have been contaminated with a bleach-based cleaner. You remain contagious for at least 48 hours after symptoms stop, so avoid preparing food for others or sharing towels during that window. If someone in your household is sick, give them their own drinking glass and keep shared spaces disinfected.
