When someone is throwing up, your first priorities are preventing choking, keeping them comfortable, and making sure they stay hydrated once the vomiting slows. Most vomiting episodes resolve on their own within 12 to 24 hours, but how you respond in the moment and the hours that follow makes a real difference in recovery.
Keep Their Airway Clear
The biggest immediate risk when someone is vomiting is choking, especially if they’re drowsy, intoxicated, or lying down. If the person is alert and upright, have them lean forward slightly over a bucket or toilet. This lets gravity do the work and keeps vomit from entering the airway.
If the person is lying down or too weak to sit up, roll them onto their side into what’s called the recovery position. Bend the knee of their top leg at a right angle to keep them stable, and tilt their head back slightly with their chin lifted to keep the airway open. This ensures any vomit drains out of the mouth rather than pooling in the throat. If you suspect a spinal injury, don’t move them. Instead, gently lift the jaw with your fingertips from both sides to open the airway without shifting the neck.
Stay with the person while they’re actively vomiting. Between episodes, help them rinse their mouth with water (not swallow it yet) to clear stomach acid that can damage teeth and irritate the throat.
Wait Before Offering Fluids
The instinct to push water right away is understandable, but drinking too much too soon often triggers another round of vomiting. Once the active vomiting has stopped, wait 15 to 30 minutes before offering anything to drink.
When you do start fluids, go small. Begin with about one teaspoon (5 mL) every one to two minutes. A teaspoon, syringe, or even a medicine dropper works well for controlling the amount. If that stays down, gradually increase the volume over the next hour or two. This approach works for both adults and children, and more than 90% of people can be successfully rehydrated this way even after significant vomiting.
The best options are water, an oral rehydration solution (available at any pharmacy), clear broth, or diluted juice. Avoid milk, caffeinated drinks, alcohol, and anything carbonated for the first several hours. Ice chips are another good starting point if even small sips feel like too much.
Watch for Signs of Dehydration
Repeated vomiting pulls fluid and electrolytes out of the body fast. Knowing what dehydration looks like helps you decide whether home care is enough or whether the person needs medical attention.
In adults, watch for excessive thirst, a dry or sticky mouth, dark yellow urine, urinating much less than usual, dizziness when standing, and general weakness. In children, the signs can be more subtle. Sunken eyes, a lack of tears when crying, decreased skin elasticity (if you gently pinch the skin on the back of their hand and it stays “tented” rather than snapping back), and a weak or rapid pulse all suggest meaningful fluid loss. A child who hasn’t had a wet diaper in three hours or an older child who hasn’t urinated in six to eight hours needs prompt attention.
Reintroduce Food Slowly
There’s no rush to eat. Once the vomiting has stopped for several hours and small amounts of fluid are staying down, bland foods are the safest starting point. You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. Those foods are fine for a day or two, but there’s no clinical evidence that they’re better than other gentle options.
Brothy soups, oatmeal, boiled potatoes, crackers, and plain dry cereal are equally easy on the stomach. Once things feel more settled, you can expand to cooked carrots, sweet potatoes without the skin, avocado, skinless chicken or turkey, fish, and eggs. These provide the protein and nutrients the body needs to recover, which a strict BRAT diet lacks. Avoid greasy, spicy, or heavily seasoned foods until the person feels fully back to normal.
Try Ginger for Lingering Nausea
If nausea is hanging around between vomiting episodes, ginger is one of the few home remedies with solid clinical support. It works by speeding up how quickly the stomach empties and by blocking certain chemical signals in the gut that trigger the vomiting reflex. Effective doses in studies range from about 1 to 2 grams per day. That’s roughly a thumb-sized piece of fresh ginger steeped in hot water as tea, or a couple of ginger capsules from the supplement aisle. Ginger ale is popular but most brands contain very little actual ginger, so fresh ginger or ginger supplements are more reliable.
Protect Yourself and Clean Up Safely
Vomiting is often caused by highly contagious viruses like norovirus, which can survive on surfaces for days. If you’re caring for someone who’s throwing up, protecting yourself matters.
Wear disposable gloves when cleaning up. Wipe away visible vomit first with paper towels, then disinfect the area with a bleach solution: 5 to 25 tablespoons of standard household bleach per gallon of water. Let the solution sit on the surface for at least five minutes before wiping it away. Regular household cleaners and antibacterial sprays are not strong enough to kill norovirus. If bleach isn’t available, look for an EPA-registered disinfectant specifically labeled as effective against norovirus.
Wash any contaminated clothing or bedding separately in hot water with detergent, and dry on the highest heat setting. Wash your hands thoroughly with soap and water afterward. Hand sanitizer is less effective against norovirus than actual handwashing.
When Vomiting Needs Emergency Care
Most vomiting is caused by a stomach bug, food poisoning, or something the person ate that didn’t agree with them. But certain warning signs mean the cause could be more serious.
Call 911 if the person has chest pain, severe abdominal pain or cramping, confusion, blurred vision, or a high fever combined with a stiff neck. These combinations can indicate conditions like meningitis, a heart event, or a serious abdominal emergency.
Get to an emergency room or urgent care if the vomit contains blood, looks like dark coffee grounds (a sign of bleeding in the stomach), or is bright green (which can indicate a bowel obstruction). Vomit that smells like feces also warrants immediate attention, as it can signal a blockage deep in the intestines. Persistent vomiting lasting more than 24 hours in adults, or 12 hours in young children, combined with an inability to keep any fluids down is another reason to seek care, since IV fluids may be needed to correct dehydration that oral rehydration can’t fix.
A severe, sudden headache alongside vomiting, particularly one that feels unlike any headache the person has had before, also needs urgent evaluation.
