The most important thing you can do after vomiting is give your stomach a short break, then slowly reintroduce fluids. Wait 30 to 60 minutes after your last episode before taking small sips of water. Rushing food or drink too soon often triggers another round. Beyond that initial rest period, a few simple strategies can ease nausea, prevent dehydration, and help you recover faster.
Give Your Stomach Time to Rest
After throwing up, your stomach muscles and digestive system are irritated. Putting anything in right away, even water, can set off another episode. Wait at least 30 to 60 minutes before trying clear fluids. If you vomit again, reset the clock and wait another 30 to 60 minutes before trying again.
During this rest period, focus on staying as still and comfortable as possible. Sit upright or recline at a slight angle. Lying flat on your back is risky because vomit can block your airway. If you need to lie down, turn onto your side with your top knee bent and touching the ground, your head angled slightly downward so any fluid drains out of your mouth rather than back toward your throat. Pregnant people should always lie on their left side to avoid pressure on a major vein.
Reintroduce Fluids Slowly
Once you’ve kept that initial waiting period, start with ice chips or very small sips of water, roughly every 15 minutes. The goal isn’t to quench your thirst all at once. It’s to test whether your stomach can hold anything down. If water stays down for an hour or so, you can expand to other clear fluids: clear broth, diluted electrolyte drinks, ice pops, or gelatin.
Replacing electrolytes matters more than most people realize. Vomiting drains your body of chloride and potassium in particular. In one emergency department study, nearly half of patients who came in with vomiting alone had low chloride levels, and over a third had low potassium. These losses can cause muscle weakness, dizziness, and fatigue that linger even after the nausea passes. An oral rehydration solution or diluted sports drink helps replace what plain water can’t.
What to Eat After Vomiting
Once you’ve tolerated clear liquids for a few hours, your appetite may start to creep back. Start small with bland, easy-to-digest foods: plain toast, crackers, bananas, applesauce, or plain oatmeal. These are gentle on an irritated stomach and unlikely to trigger more nausea.
Avoid greasy, spicy, or dairy-heavy foods for at least 24 hours. Rich foods require more digestive effort, and your stomach isn’t ready for that yet. Eat small portions rather than full meals, and stop if nausea returns. Most people can get back to a normal diet within a day or two as symptoms fade.
Try Ginger for Nausea Relief
Ginger is one of the best-studied natural remedies for nausea and vomiting. The active compounds in ginger work by blocking serotonin receptors involved in the vomiting reflex, essentially interrupting the signal between your gut and brain that triggers the urge to throw up. Ginger also helps your stomach empty more efficiently, which reduces that heavy, nauseated feeling.
A systematic review of clinical trials found that ginger supplements at doses up to 1 gram per day, taken for more than four days, reduced the odds of vomiting by 70% compared to a placebo. You don’t need a supplement to get the benefit. Ginger tea, ginger chews, or even flat ginger ale (with real ginger) can help, though a concentrated form like ginger capsules delivers a more consistent dose.
Use the Pressure Point on Your Wrist
There’s a spot on the inside of your wrist called PC6, located about two to three finger-widths below where your palm meets your wrist, right between the two tendons. Pressing firmly on this point has been shown to reduce nausea and vomiting with surprisingly strong evidence behind it. A Cochrane review of 45 trials found that stimulating this point reduced vomiting by about 40% compared to a sham treatment, and performed just as well as anti-nausea medications in head-to-head comparisons.
You can press the point with your thumb for a few minutes at a time, or use a commercially available acupressure wristband that applies steady pressure. Side effects are minimal, mostly limited to occasional skin irritation from the bands. It’s a useful tool when you don’t have medication on hand or want to avoid adding anything to an already upset stomach.
Over-the-Counter Medications
Bismuth subsalicylate (the active ingredient in Pepto-Bismol and Kaopectate) can help with nausea and vomiting caused by stomach bugs or general stomach upset. It works by coating the stomach lining and reducing inflammation. One important restriction: don’t give it to children under 12, or to any child or teenager who might have the flu or chickenpox, because it carries a risk of a rare but serious condition called Reye syndrome. Anyone with an aspirin allergy should also avoid it, since bismuth subsalicylate is a salicylate compound.
Antihistamine-based anti-nausea products, often sold for motion sickness, can also help with general nausea. These tend to cause drowsiness, which can actually be useful if vomiting is keeping you from resting.
Watch for Dehydration
Dehydration is the main complication of repeated vomiting, especially in children and older adults. The signs to watch for are straightforward: dark-colored urine or urinating much less than usual, a dry mouth, and skin that stays “tented” when you pinch it rather than flattening back immediately. In infants, no wet diapers for three hours is a key warning sign. Dizziness or lightheadedness when you stand up also signals that fluid levels have dropped significantly.
Warning Signs That Need Emergency Care
Most vomiting resolves on its own within 12 to 24 hours, but certain symptoms alongside vomiting point to something more serious. Get emergency help if vomiting comes with chest pain, severe abdominal cramping, confusion, blurred vision, or a high fever with a stiff neck. Vomit that contains blood, looks like dark coffee grounds, is bright green, or has a fecal smell or appearance all require immediate evaluation.
A severe headache alongside vomiting, particularly one that feels different from any headache you’ve had before, also warrants urgent care. The same goes for signs of significant dehydration that aren’t improving with small sips of fluid: persistent dizziness, extreme thirst, weakness, and very dark or absent urine despite trying to drink.
