Question:
My child was recovering from the stomach flu, but while eating dinner, they suddenly threw up a large amount, including what they had eaten for lunch. Is this because their digestive system hasn't fully recovered yet? Do I need to go back to feeding them a bland diet like rice porridge for a few more days?
Answer:
You must have been very surprised that your child vomited again during their recovery.
[Current Situation Summary]
If your child suddenly vomited during the recovery phase of gastroenteritis (stomach flu) and even threw up their lunch, it is likely that their digestive function has not fully returned, or the amount and type of food were increased too quickly.
[What to Do Now]
• Fast for 1-2 hours → Let the stomach rest.
• After that, start giving 1-2 teaspoons of water every 5-10 minutes → If they hold it down for 30 minutes, gradually increase the amount.
• If they do not vomit → Retry feeding a very small amount (2-3 spoons) of white rice porridge or thin gruel.
• Avoid greasy food, milk, fruit, and meat for another 1-2 days.
[Warning Signs — See a doctor today if you notice any of these]
• Repeated vomiting (2-3 times or more)
• No urination for more than 8 hours
• Dry lips, sunken eyes, or extreme lethargy
• Abdominal pain that becomes increasingly severe, or bloody stools
• Accompanied by a fever (38°C / 100.4°F or higher)
[Pacing the Recovery Diet]
• Today: Small amounts of white rice porridge or thin gruel.
• Days 1-2: Add bananas, boiled potatoes, and plain toast.
• Days 3-4: Soft rice with a small amount of chicken breast.
• Once they tolerate this progression well, you can return to their normal diet.
Right now, the key is to feed them slowly and frequently rather than focusing on the portion size. If your child does not vomit again by tomorrow morning and urinates normally → you can continue to observe them at home.
