<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi my 21 month old toddler has had diarrhea the past 3 - 4 days. He has been refusing to ingest anything besides milk and rice cereal. If I try to get him to eat anything else he gags and on one instance puked. His poops have been graywhitetan in colour as well. He has been generally happy and playful though. Does this just sound like a stomach bug or could it be something more serious?  <response>: Hello, If a similar patient comes to my old as u have mentioned that child is playful Nd happy, Its nothing serious. You can give ORS sachet mixed In 1 liter of boiled water Lukewarm within a day, Sporadic sachet two times a day and zinc 5 ml at night.
