The Importance of Rehydration After Vomiting
Vomiting causes a rapid loss of fluids and essential minerals, known as electrolytes, like sodium and potassium. This can quickly lead to dehydration, especially in children and the elderly. Restoring these lost fluids and electrolytes is the first and most critical step in recovery. However, reintroducing fluids too quickly or choosing the wrong type can trigger more vomiting, starting a difficult cycle. The key is to wait for your stomach to settle and then introduce liquids slowly and gently.
The Best Drinks for Settling an Upset Stomach
Clear Liquids: The Gentle Start
After a bout of vomiting, clear liquids are the safest way to begin rehydrating. They are less likely to irritate the stomach and are easily absorbed.
- Water: Plain water is the most fundamental choice for hydration. Sucking on ice chips can also work well, providing slow and steady hydration without overwhelming the stomach.
- Clear Broth: Clear vegetable or chicken broth provides fluids and some sodium, an electrolyte lost through vomiting. It is also comforting and easy to tolerate.
- Diluted Juice: Fruit juices can be high in sugar, which may worsen an upset stomach. Diluting a non-citrus juice like apple or grape juice with water can make it more palatable and gentler on the digestive system.
- Weak Tea: Herbal teas, such as ginger or peppermint tea, are known for their stomach-soothing properties. Decaffeinated teas are recommended to avoid further irritation.
- Gelatin and Popsicles: For those who find it difficult to sip, popsicles and gelatin made from clear liquids can be an excellent alternative.
Electrolyte-Replacing Solutions
For more significant fluid loss, or if vomiting has been persistent, replacing electrolytes is crucial.
- Oral Rehydration Solutions (ORS): Products like Pedialyte are specifically formulated with the optimal balance of sugar and electrolytes to promote fluid absorption. They are highly recommended for children and adults with moderate dehydration.
- Diluted Sports Drinks: While sports drinks like Gatorade contain electrolytes, they are often high in sugar and should be diluted with water (e.g., half water, half sports drink) to prevent worsening diarrhea.
- Coconut Water: A natural source of electrolytes, coconut water is sometimes suggested, but it may not contain enough sodium for severe fluid loss.
Comparison of Common Post-Vomiting Drinks
| Drink Type | Benefits | Potential Downsides | Best For |
|---|---|---|---|
| Plain Water | Easiest to tolerate; essential for hydration. | Contains no electrolytes; may not be sufficient for severe dehydration. | Mild nausea and initial rehydration after the stomach has settled. |
| Clear Broth | Replenishes sodium; soothing to the stomach; contains some nutrients. | Doesn't replace a full range of electrolytes. | Initial phase of rehydration and soothing the digestive tract. |
| Oral Rehydration Solution (ORS) | Optimal balance of electrolytes and sugar; highly effective for rehydration. | Can be expensive; some may dislike the taste. | Moderate to severe dehydration, especially in children and the elderly. |
| Ginger Tea (Decaffeinated) | Proven anti-nausea properties from compounds like gingerols. | Can cause heartburn in some individuals. | Easing persistent nausea alongside rehydration. |
| Diluted Sports Drink | Replaces electrolytes and provides some energy. | High sugar content can worsen diarrhea or irritate the stomach if not diluted. | When minor electrolyte replenishment is needed and tolerability is good. |
How to Reintroduce Fluids Slowly and Safely
Starting with the right fluid is only half the battle; the method of consumption is equally important. Consuming liquids too quickly can overload a sensitive stomach and induce another episode of vomiting.
- Wait and Rest: After vomiting, it's best to wait for about 30 to 60 minutes to let your stomach calm down. Rest is vital to help your body recover.
- Sip Slowly: When you are ready, take very small sips—a few teaspoons at a time. Wait a few minutes to see how your stomach reacts before taking another small sip. Ice chips are an excellent way to force yourself to go slowly.
- Start with Bland: Stick to the clear liquids first before moving on to electrolyte-rich options. If you feel comfortable, you can gradually increase the quantity over the next few hours.
- Watch for Signals: Pay attention to how your body feels. If nausea returns, stop drinking for a while and restart with even smaller amounts. If you can keep fluids down for several hours, you can gradually progress to eating bland, easily digestible foods like the BRAT diet (bananas, rice, applesauce, toast).
- Stay Cautious with Sugary or Caffeinated Drinks: Avoid drinks high in sugar, such as undiluted fruit juice or soda, which can make things worse. Also, stay away from caffeine and alcohol, as they can lead to further dehydration and irritation.
Conclusion
To answer what drink settles the stomach after vomiting, the primary goal is gentle, slow rehydration. Start with small sips of clear liquids like water, ice chips, or clear broth. As your stomach settles, you can transition to oral rehydration solutions or diluted sports drinks to replace lost electrolytes. Always listen to your body and reintroduce liquids gradually to ensure a smooth and steady recovery. If symptoms persist or dehydration becomes severe, seek medical attention.
How to create your own rehydration solution
If commercial electrolyte solutions are unavailable, you can create a simple oral rehydration solution at home. Mix the following ingredients with caution and precision, as incorrect proportions can be ineffective or even harmful:
- Ingredients: 1 liter (about 4 cups) of water, 6 level teaspoons of sugar, and 1/2 level teaspoon of salt.
- Directions: Boil the water and let it cool. Stir in the salt and sugar until dissolved. Sip this solution slowly, just as you would with any other rehydrating fluid.
When to Seek Medical Attention
While most cases of post-vomiting nausea can be managed at home, it is important to know when to see a doctor. If you experience any of the following, get professional medical advice:
- Vomiting that lasts for more than 24-48 hours.
- Signs of severe dehydration, such as dizziness, confusion, or dark, infrequent urination.
- Blood in your vomit.
- High fever.
- Severe abdominal pain.
Taking the right steps early on can help you recover quickly and comfortably. Find more health information at the CDC.

FAQs
What can I drink immediately after vomiting?
After a vomiting episode, wait 30-60 minutes for your stomach to settle. Then, start with very small sips of clear, non-irritating liquids like water or sucking on ice chips to avoid triggering more vomiting.
Are sports drinks like Gatorade good after vomiting?
Sports drinks can help replace electrolytes but are often high in sugar, which can worsen diarrhea and stomach upset. Diluting a sports drink with water is a better option, but oral rehydration solutions (ORS) like Pedialyte are more balanced for medical rehydration.
Can I drink ginger ale to settle my stomach?
Yes, a clear, non-caffeinated soda like ginger ale is a traditional remedy that can be sipped slowly. However, many commercial ginger ales contain little actual ginger, so ginger tea may be more effective for its anti-nausea properties.
Should I drink hot or cold fluids after vomiting?
Neither very hot nor very cold fluids are recommended, as extreme temperatures can irritate the stomach. Room-temperature or slightly cooled clear liquids are often best tolerated.
How can I tell if I'm dehydrated?
Common signs of dehydration include thirst, a dry mouth, fatigue, dizziness, and dark, infrequent urine. If you experience these symptoms, it's important to increase your fluid intake carefully.
Is it safe to make my own electrolyte solution at home?
You can create a basic oral rehydration solution by mixing 1 liter of water with 6 teaspoons of sugar and 1/2 teaspoon of salt. However, it is crucial to use exact measurements. For reliable balance, commercial oral rehydration solutions are recommended.
When can I start eating solid foods again?
Once you can keep fluids down for several hours without vomiting, you can slowly introduce bland foods like crackers, rice, bananas, and toast (the BRAT diet). Gradually reintroduce your regular diet as you feel better.
