The fastest way to stop vomiting is to rest your stomach completely for a few hours, then slowly reintroduce fluids in tiny amounts. Most vomiting from stomach bugs, food reactions, or motion sickness resolves on its own within 24 hours with the right approach. The priority is preventing dehydration while your body clears whatever triggered the episode.
What to Do Right After Vomiting
Resist the urge to drink a full glass of water immediately. Your stomach is irritated, and flooding it with liquid often triggers another round. Give yourself a grace period of one to two hours where you consume nothing at all. Lie still, breathe slowly through your nose, and avoid strong smells.
After that rest period, start with ice chips or very small sips of water, about a tablespoon every 15 minutes. If that stays down for an hour, gradually increase the amount. The goal is to keep your fluid intake slow and steady rather than gulping anything down. Clear broths, diluted apple juice, and flat ginger ale are reasonable next steps once plain water is tolerated.
Preventing Dehydration
Dehydration is the main risk from repeated vomiting, especially in children and older adults. Signs to watch for include a dry mouth, dark yellow urine, dizziness when standing, and sunken-looking eyes. In infants, the soft spot on top of the skull may appear sunken, and the skin may not flatten back right away after being gently pinched. That skin test works for adults too: pinch the back of your hand, and if the skin stays tented for a few seconds instead of snapping flat, you’re likely dehydrated.
If plain water isn’t enough, you can make a simple oral rehydration drink at home: mix 4 cups of water with half a teaspoon of table salt and 2 tablespoons of sugar. This mimics the ratio used in medical rehydration solutions and helps your body absorb the fluid more efficiently than water alone. Sip it slowly over several hours. For young children and infants, store-bought electrolyte solutions designed for kids are a safer bet than homemade versions, since the ratio matters more at small body sizes.
When to Start Eating Again
You’ve probably heard of the BRAT diet (bananas, rice, applesauce, toast), but most experts no longer recommend restricting yourself to those four foods. The current guidance is simpler: once you feel like eating, eat your normal diet. You don’t need to force food before you’re ready, but you also don’t need to limit yourself to bland items for days on end.
That said, easing back in makes practical sense. Start with small portions of foods that are easy on the stomach: plain crackers, broth-based soup, a banana, or some rice. Avoid greasy, spicy, or heavily seasoned foods for the first day. Dairy can be harder to digest when your gut is inflamed, so you may want to hold off on milk and cheese for 24 hours. If a small meal stays down, you can return to your regular eating pattern fairly quickly.
Ginger and Other Natural Approaches
Ginger has the strongest evidence of any home remedy for nausea and vomiting. Clinical trials, primarily in pregnant women, have found that 1,000 to 1,500 mg of ginger per day significantly reduces nausea. A practical dose is about 250 mg of ginger powder four times a day, which is roughly the amount in a standard ginger supplement capsule. Fresh ginger tea works too: steep a thumb-sized piece of peeled, sliced ginger in hot water for 10 minutes. Ginger chews and ginger candies are another option if the tea doesn’t appeal to you.
Peppermint can also help settle nausea. Inhaling peppermint oil or sipping peppermint tea offers mild relief for some people, though the evidence is less robust than for ginger.
Wrist Pressure Point (P6)
A technique worth trying is pressing on the P6 acupressure point on the inside of your wrist. To find it, place three fingers flat across the inside of your wrist just below the crease where your hand meets your arm. The point sits in the groove between the two large tendons, right below where your third finger lands. Press firmly with your thumb for 30 seconds to a minute. It shouldn’t hurt. This is the same principle behind anti-nausea wristbands sold in pharmacies, and it can take the edge off mild to moderate nausea.
What Makes Vomiting Worse
Several common habits can prolong vomiting or make it harder to recover. Lying flat on your back increases the chance of triggering your gag reflex, so prop yourself up or lie on your side. Strong odors from cooking, perfume, or cleaning products can restimulate nausea, so keep your environment as scent-free as possible. Brushing your teeth immediately after vomiting feels instinctive but can irritate your stomach further. Instead, rinse your mouth with water or a baking soda solution (one teaspoon in a cup of water) to neutralize stomach acid on your teeth.
Avoid alcohol, caffeine, and carbonated drinks during the acute phase. All three can irritate your stomach lining and make vomiting more likely to return. Smoking has the same effect.
Over-the-Counter Options
Antihistamine-based motion sickness medications can help if your nausea is related to travel or dizziness. These work best when taken before the nausea starts, so they’re more useful for prevention than for stopping vomiting already in progress. Bismuth subsalicylate (the active ingredient in Pepto-Bismol) can calm an upset stomach for adults, though it’s not appropriate for children. If vomiting is severe enough that you can’t keep anything down, including medications, talk to a pharmacist about options that dissolve on the tongue or are applied as a patch.
Recovery Timeline
Most vomiting from viral stomach bugs follows a predictable pattern. The worst of it typically passes within 6 to 12 hours. You may feel queasy for another day or two, but active vomiting that lasts beyond 48 hours in adults is unusual and worth a medical call. For children under 2, the threshold is 24 hours. For infants, it’s 12 hours.
Your appetite may take several days to fully return, and that’s normal. Eating smaller, more frequent meals during recovery is easier on your digestive system than three large ones. Most people feel back to normal within three to five days of a standard stomach virus.
Warning Signs That Need Medical Attention
Some types of vomiting signal something more serious than a stomach bug. Get to an emergency room if your vomit contains blood, looks like coffee grounds, or has a fecal odor. Chest pain, severe abdominal cramping, confusion, blurred vision, or a combination of high fever and stiff neck alongside vomiting all warrant calling 911.
Seek urgent care if vomiting comes with a severe headache unlike any you’ve had before, or if you’re showing clear signs of dehydration that aren’t improving with small sips of fluid: extreme thirst, very dark urine, weakness, or dizziness every time you stand. Green vomit (which can indicate bile) also deserves prompt evaluation. If you’ve been dealing with recurring nausea and vomiting for more than a month, or you’ve noticed unexplained weight loss alongside it, schedule an appointment with your doctor even if the episodes seem manageable on their own.
