So if you have a child who is throwing up because they have a food allergy or they have a food intolerance, to the child it does not really matter why they are throwing up. It is the same symptom. Really the difference is between a food allergy and a food intolerance is the mechanism by which it occurs. Food allergies are caused by your immune system for some reason thinking that the food is harmful to your body and in a way trying to reject it. Food intolerances, there are multiple, multiple mechanisms why someone would have a food intolerance. It could be genetic. They may have certain enzymes they are missing such as lactose deficiency. And so, the types of symptoms that you are getting are very similar. It is just a mechanism that is different between the two.
