After vomiting, wait at least two hours before putting anything in your stomach, then start with small sips of clear liquids. Jumping straight to solid food too soon can trigger another round of nausea. The goal in those first hours is replacing lost fluid and electrolytes, then gradually reintroducing easy-to-digest foods over the next 12 to 24 hours.
The First Two Hours: Nothing but Rest
Your stomach needs a break. For two hours after your last episode of vomiting, avoid eating or drinking anything. This gives your stomach lining time to settle and reduces the chance that putting something in will send it right back up. If you feel thirsty, resist the urge to gulp water. Just wait it out.
Hours Two Through Six: Clear Liquids Only
Once two hours have passed, start with small sips of clear liquid, not full glasses. A few sips every five to ten minutes is the right pace. If that stays down for 30 minutes, you can gradually increase the amount. Good options at this stage include water, weak tea, clear broth, diluted apple juice, or popsicles.
Vomiting drains your body of sodium, potassium, and water. Plain water alone doesn’t replace those lost electrolytes, so a simple rehydration drink helps. You can make one at home with ingredients you probably already have: mix four cups of water with half a teaspoon of salt and two tablespoons of sugar. That’s based on the World Health Organization’s formula. If you have sports drinks on hand, dilute them (about one and a half cups of Gatorade mixed with two and a half cups of water plus half a teaspoon of salt). Broth-based options work well too: dissolve a bouillon cube in four cups of water with a quarter teaspoon of salt and two tablespoons of sugar.
Avoid anything carbonated, caffeinated, or acidic at this stage. Coffee, soda, and citrus juices can all increase stomach acid production or irritate an already raw stomach lining.
Your First Solid Food
Once you can keep clear liquids down comfortably for a few hours, you can try a small amount of soft, bland food. “Small” is the key word here. Eat a few bites, then stop and wait. If your stomach tolerates it after 15 to 20 minutes, have a few more. Eating small amounts frequently throughout the day is far easier on your stomach than sitting down to a full meal.
The best first foods share three qualities: they’re low in fat, low in fiber, and gentle in flavor. Fat slows stomach emptying, which keeps food sitting in your stomach longer and increases the chance of nausea returning. Fiber does the same thing. Stick with foods that move through your system easily.
Good choices for your first solid meal include:
- Plain white rice or white toast: Simple starches that digest quickly
- Bananas: Soft, mild, and a natural source of potassium you’ve lost
- Applesauce: Easy to get down even when your appetite is low
- Plain crackers: Saltines or graham crackers provide salt and simple carbs
- Boiled or mashed potatoes: Without butter or cream, these are gentle and filling
- Cream of wheat or plain oatmeal: Warm, soft, and easy on the stomach
- Broth-based soup: Combines hydration with a small amount of nutrition
- Gelatin or pudding: If you need something that goes down easily
You may have heard of the BRAT diet (bananas, rice, applesauce, toast). It’s fine for the first day or two, but there’s no research showing it works better than a broader bland diet. Harvard Health Publishing notes that restricting yourself to only those four foods isn’t necessary. Brothy soups, potatoes, crackers, and unsweetened cereal are equally easy to digest and give you more variety.
Adding More Nutritious Foods
Once plain starches are sitting well, typically within 12 to 24 hours, start adding foods with more nutritional value. Your body needs protein and vitamins to recover, and bland starches alone won’t provide them. Cooked carrots, butternut squash, sweet potatoes without the skin, avocado, scrambled eggs, skinless chicken or turkey, and mild white fish are all good next steps. These foods are still easy to digest but give your body building blocks it needs.
Continue eating smaller portions more frequently rather than three big meals. Chew slowly and thoroughly. Your stomach is still recovering, and overwhelming it with volume can bring nausea back.
What to Avoid for 24 to 48 Hours
Some foods and drinks are significantly harder on a recovering stomach. Skip these until you’re feeling fully back to normal:
- Fried or greasy foods: High in saturated fat, they take much longer to break down and sit heavy in your stomach
- Spicy foods: Can irritate the stomach lining and trigger nausea or diarrhea
- Dairy (especially full-fat): Many people have temporary difficulty digesting lactose after a stomach illness, even if they normally tolerate it fine
- Alcohol: Directly irritates the gut lining and can cause more nausea and vomiting
- Coffee and caffeinated drinks: Stimulate acid production in the stomach
- Carbonated beverages: The fizz can worsen acid reflux symptoms
- High-fiber foods: Raw vegetables, whole grains, beans, and nuts slow stomach emptying and can form hard-to-digest masses
- Citrus and tomato-based foods: Their acidity can aggravate an already sensitive stomach
Also be cautious with common pain relievers like ibuprofen and aspirin, which can increase nausea. If you need pain relief, acetaminophen is generally easier on the stomach.
Signs You’re Getting Dehydrated
The biggest risk after vomiting isn’t hunger. It’s dehydration. Watch for dark yellow urine, infrequent urination, dry mouth, dizziness when standing, or a headache that won’t quit. In adults, these are signals to be more aggressive with fluid replacement using an electrolyte solution rather than plain water.
If you can’t keep even small sips of liquid down for more than several hours, or if you notice extreme fatigue, confusion, or unresponsiveness, that’s a sign of serious dehydration that needs medical attention. Children and older adults reach this point faster than healthy younger adults.
