<human>: Hi, my 4 year old son has been vomitting and had diarrhea for well over a month. He has no fever with it at all. He is ok for a couple of days and then starts it all over for 2 to 5 days. He has seen the doctor and they can t figure anything out. He has lost 10 lbs in like 3 weeks. He is already so little for his age. Please help me, I am running outta options.
<bot>: Hello, You tell me your toddler is having intermittent vomiting and diarrhea.  The intermittent aspect of his illness suggests that he might have cyclic vomiting syn Chat Doctor.  About one-third of the child who have vomiting also have diarrhea. He is the right age. Usually, the diagnosis is more likely if there has been a longer history of illness.  However, he has had a significant weight loss, and it would not be in his best interest to wait any longer.  I want you to take him for evaluation to a pediatric gastroenterologist AS SOON AS YOU CAN. Hope I have answered your query. Let me know if I can assist you further. Take care
