What causes vomiting in a child after feeding particular food?
Patient: I have an 18 month old and in the past have fed her fish on 3 separate occasions and she got violently ill. Vomiting everywhere for a couple hours. I wasn t sure if it was the fish that did it till this 4th time I tried and the same thing occurred only this time it made her lifeless after. Scared me!! I will stop feeding it to her now that I know its the fish. What I m wondering is, does this sound like this is an allergy and if it happens again that she eats it by accident could her reaction be worse. Doctor: Hello. I just read through your question. This can most definitely be a good allergy to fish. I recommend discussing this with your pediatrician.  Until then,  avoid fish.
