Step 1: Rest Your Stomach Before Starting Rehydration
Immediately after vomiting, your stomach needs time to settle. Attempting to drink or eat too soon can trigger another episode, undoing your rehydration efforts.
Best practices during this period:
- Wait 30 to 60 minutes after the last episode of vomiting before attempting any fluids.
- If you feel thirsty during this time, you can rinse your mouth with water without swallowing or suck on a small piece of ice or a popsicle.
- Rest quietly during this time, as excessive movement can also trigger a sensitive stomach.
Step 2: Begin with Small, Frequent Sips of Clear Fluids
Once your stomach has settled, the rehydration process can begin. The key is to start with clear liquids and introduce them slowly to avoid overwhelming your system.
Recommended clear fluids:
- Oral Rehydration Solutions (ORS): These are specifically formulated to replace water, salts, and sugars lost during vomiting. Brands like Pedialyte or DripDrop are widely available and highly effective.
- Clear Broth: Chicken or vegetable broth provides essential sodium and other electrolytes in a savory, soothing form.
- Diluted Juices: Watered-down apple juice is a good option, especially for children who may not like the taste of ORS. Avoid full-strength juices, as the high sugar content can worsen diarrhea.
- Weak Herbal Tea: Ginger or chamomile tea can be soothing for the stomach. Ensure it's weak and decaffeinated.
- Ice Chips/Popsicles: If you're struggling to keep any liquid down, sucking on ice chips or ORS-based popsicles can provide hydration in a manageable dose.
How to sip fluids:
- Start with just a teaspoon (5 mL) or a small sip every 10 to 15 minutes.
- Gradually increase the amount if you tolerate it without any returning nausea.
- Avoid gulping down a full glass of water, as this can easily cause another round of vomiting.
Step 3: Transition to Bland Foods (BRAT Diet)
After you've successfully kept down clear liquids for several hours (typically 6-8 hours for adults), you can slowly introduce bland, easy-to-digest foods. The BRAT diet is a time-tested approach for this transition.
- Bananas: Rich in potassium to help replace lost electrolytes.
- Rice: Plain, white rice is easy on the digestive system.
- Applesauce: A simple source of calories and nutrients.
- Toast: Plain, dry toast is a simple carbohydrate that won't irritate the stomach.
Gradually reintroduce these foods in small, frequent portions. If your nausea returns, pause eating and go back to clear liquids for a while.
Step 4: Avoid Irritating Foods and Drinks
Certain foods and beverages can exacerbate stomach upset and should be avoided during recovery.
- High-Sugar Beverages: Sweetened juices, sodas, and sports drinks often contain too much sugar, which can pull fluid into the digestive tract and worsen symptoms.
- Dairy Products: Many people have difficulty digesting milk and other dairy products after a stomach bug, so it's best to avoid them for a few days.
- Fatty and Spicy Foods: These require more effort for your digestive system to process and can trigger nausea.
- Caffeine and Alcohol: Both are diuretics and can worsen dehydration.
Comparison of Rehydration Fluids
To help you choose the right fluids, here is a comparison of common rehydration options:
| Fluid Type | Best For | Pros | Cons |
|---|---|---|---|
| Oral Rehydration Solution (ORS) | Mild to moderate dehydration, adults and children | Balanced mix of electrolytes and glucose for optimal absorption. | Can have an unpleasant taste. |
| Water | Mild dehydration | Universally available, simple, and effective. | Lacks electrolytes needed for more significant fluid loss. |
| Clear Broth | Mild dehydration, appetite loss | Soothing and provides sodium and other minerals. | Limited nutritional value and may not provide enough electrolytes. |
| Diluted Fruit Juice | Mild dehydration (especially in children who refuse ORS) | Tastes better than ORS and provides some glucose. | High sugar content if not diluted; can worsen diarrhea. |
| Sports Drink | Post-exercise rehydration, mild dehydration | Replenishes electrolytes and provides energy. | High in sugar; can worsen dehydration if not diluted. |
Conclusion
Knowing how to rehydrate after vomiting is a critical skill for managing illness at home and preventing more severe complications like dehydration. The process involves a structured, gradual approach: first, resting the stomach; second, sipping clear, balanced fluids like Oral Rehydration Solutions; and third, carefully reintroducing bland foods. By following this process and avoiding potentially irritating foods and drinks, you can help your body recover smoothly and restore its fluid and electrolyte balance effectively. Always pay close attention to your body's signals and do not hesitate to seek professional medical advice if symptoms persist or worsen.
When to Seek Medical Attention
While most cases of vomiting can be managed at home, it's important to know when to see a doctor. Seek medical advice if:
- Vomiting continues for more than 24-48 hours.
- You are unable to keep any fluids down.
- You experience severe abdominal pain.
- There are signs of severe dehydration, such as dizziness, confusion, or little to no urination.
- You have blood in your vomit or black, tarry stools.
- A fever of 101°F (38.3°C) or higher persists for more than three days.

What to Do for a Dehydrated Child
Young children are more susceptible to dehydration. If a child is vomiting, encourage them to rest and offer small, frequent sips of an Oral Rehydration Solution (ORS). For infants, continue breastfeeding or offer formula, but do not give plain water. For older children, a diluted sports drink can be used, but ORS is generally preferred. Consult a pediatrician if you have concerns, as severe dehydration in a child is a medical emergency.
