My 3.5 year old son had a stomach flu about a week ago with the standard low-grade fever and throwing up for about 24 hours. His appetite hasn t returned, and for the last 3 days he s been complaining that his belly hurts. Tonight he started crying and went to go throw up, which he did, and it smelled strongly of yeast. His throw up from a week ago did not smell that way. What could that be?
Hi...your son seems to be going through a viral diarrhea. It is quite common in diarrhea to lose some appetite for 1-2 weeks. Occasional throwing up with yeast smell is usual. Will tell you when you need to worry. Unless the kids having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome.
