Question:
Hello, my 39-month-old started vomiting around 6 PM. Earlier, they ate a rice cake and a chocolate bar. Initially, some food came up, but now it's just foam. There is no fever or diarrhea. I'm worried about dehydration, so I've been giving a sports drink, but my child vomits it right back up. Could this just be indigestion? Should I continue giving fluids?
Answer:
Hello, I understand you must be very worried about your 39-month-old's persistent vomiting.
⚠️ The current situation is concerning.
Vomiting for over 4 hours + vomiting foam requires immediate medical attention.
【Check Immediately】
• Is your child lethargic or slow to respond?
• Are their lips or the inside of their mouth dry?
• Are there tears when they cry?
【Right Now】
→ Go to the emergency room or an urgent pediatric clinic.
→ Stop giving sports drinks and do not give anything else by mouth.
→ Record the time and nature of the vomiting to show the doctor.
【Reasons to Go to the ER】
• Vomiting lasting more than 4 hours
• Vomiting foam (a sign that the stomach is empty)
• Inability to keep fluids down
• High risk of dehydration
While it could be indigestion, this level of persistent vomiting likely requires a medical evaluation and possibly IV fluids.
Please seek medical attention immediately. I hope your child feels better soon.
