The fastest way to stop throwing up is to stop fighting your body’s urge, let the episode pass, then focus on what you do in the minutes and hours afterward. Most vomiting from stomach bugs, food reactions, or motion sickness resolves on its own within 12 to 48 hours. What matters most is how you rehydrate, what you eat (and when), and which simple techniques can calm the nausea between episodes.
What to Do Right After Vomiting
Once a vomiting episode passes, resist the urge to drink a full glass of water immediately. Your stomach is irritated, and flooding it with liquid can trigger another round. Instead, wait about 15 to 30 minutes, then start with very small sips of water or an oral rehydration solution. A good starting target is roughly 1 to 2 tablespoons every five minutes. If that stays down for 30 minutes, you can gradually increase the amount.
Oral rehydration solutions (sold as Pedialyte or store-brand equivalents) work better than plain water because vomiting depletes your body of sodium, potassium, and sugar that plain water doesn’t replace. Clinical guidelines recommend 50 to 100 milliliters per kilogram of body weight over four hours for someone who is mildly dehydrated. For a 150-pound adult, that works out to roughly 3 to 7 liters over four hours, but in practice you drink as much as your stomach tolerates in small, steady sips. If you don’t have a rehydration solution on hand, diluted juice or broth with a few crackers can fill the gap temporarily.
Techniques That Calm Nausea
A pressure point on the inner wrist called P6 has decent evidence behind it for mild nausea, including morning sickness and post-surgical nausea. To find it, place three fingers flat across the inside of your wrist, starting just below the crease where your hand meets your arm. The point sits just below where your third finger lands, in the groove between the two large tendons that run down toward your palm. Press firmly with your thumb for one to two minutes. It shouldn’t hurt. This is the same spot targeted by anti-nausea wristbands sold in pharmacies.
A few environmental changes also help. Fresh, cool air across the face reduces the urge to vomit, so open a window or sit near a fan. Strong smells, especially cooking odors, are a common nausea trigger, so avoid the kitchen and keep your space well-ventilated. Lying flat can worsen nausea because stomach acid moves more easily toward the esophagus. Sit upright or recline at a 45-degree angle instead. Slow, deliberate breathing (inhale for four counts, exhale for four counts) activates a calming response that can interrupt the nausea cycle.
Ginger Actually Works
Ginger is one of the few home remedies with real clinical data behind it. Multiple trials across pregnancy-related nausea, chemotherapy side effects, and post-surgical vomiting have tested it, and most find it reduces both the frequency and severity of nausea compared to placebo. The effective dose in most studies is about 1,000 milligrams (1 gram) of ginger root per day, typically split into smaller doses taken throughout the day.
You can get this from ginger capsules sold in supplement aisles, or from real ginger tea made by steeping about a tablespoon of freshly grated ginger root in hot water for 10 minutes. Ginger ale is less reliable because many brands use artificial ginger flavoring and contain large amounts of sugar, which can make nausea worse. If you’re using capsules, look for products standardized to contain gingerols, the active compounds. A 250-milligram capsule taken four times daily is a common dosing pattern used across clinical trials.
What to Eat (and What to Skip)
You may have heard of the BRAT diet: bananas, rice, applesauce, and toast. It used to be the standard recommendation for upset stomachs, but it’s no longer endorsed by the American Academy of Pediatrics or most gastroenterologists. The problem is that it lacks protein, calcium, vitamin B12, and fiber, all things your body needs to actually recover. Following it strictly for more than 24 hours can slow healing, particularly in children.
The better approach is to think of BRAT foods as a starting point, not a complete plan. When you feel ready to eat (don’t force it), begin with small portions of bland, soft foods: plain crackers, broth-based soup, boiled potatoes, plain pasta, or scrambled eggs. As your stomach settles, add more variety. Most people can return to a normal diet within a day or two. Avoid greasy, spicy, or heavily seasoned foods until you’ve kept bland food down comfortably for several hours. Dairy can be harder to digest when your gut is inflamed, so hold off on milk and cheese initially.
Eating small amounts frequently is easier on your stomach than three large meals. Think five or six mini-meals rather than trying to make up for lost calories all at once.
Common Causes and How Long They Last
Stomach viruses (often called “stomach flu,” though they’re unrelated to influenza) are the most common cause of sudden vomiting in otherwise healthy people. They typically run their course in one to three days. Food poisoning follows a similar timeline but often hits faster and harder, usually within 6 to 12 hours of eating contaminated food.
Motion sickness, migraines, medication side effects, and anxiety can all trigger vomiting too. With these causes, treating the underlying trigger is what ultimately stops the vomiting. For motion sickness, focusing on the horizon and sitting in a position with minimal movement (front seat of a car, over the wing on a plane) helps. For medication-related nausea, taking pills with food or at bedtime often reduces the problem.
Signs That Need Medical Attention
Most vomiting is unpleasant but not dangerous. However, certain patterns signal something more serious. According to Mayo Clinic guidelines, you should seek care if:
- Duration: Vomiting 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, dark-colored urine, dry mouth, infrequent urination, dizziness, or lightheadedness when standing.
- Vomit appearance: Vomit that contains blood, looks like coffee grounds (a sign of digested blood), or is bright green (which can indicate bile from an intestinal blockage).
Severe abdominal pain between vomiting episodes, high fever above 103°F, or confusion alongside vomiting also warrant prompt evaluation. Children and older adults dehydrate faster than healthy adults, so the window for “wait and see” is shorter with those groups.
What to Avoid While Nauseous
Some common instincts actually make vomiting worse. Drinking large gulps of water, eating a full meal to “settle your stomach,” and lying completely flat are all counterproductive. Carbonated drinks can increase stomach pressure and trigger another episode. Alcohol is a stomach irritant and a dehydrator, so it compounds the problem in both directions.
Brushing your teeth immediately after vomiting feels logical, but stomach acid softens tooth enamel temporarily. Brushing right away can scrub that softened layer off. Rinse your mouth with water or a baking soda solution (one teaspoon in a cup of water) instead, then wait 30 minutes before brushing.
