If your child has trouble breathing or diarrhea after eating, you may suspect a food allergy, but sometimes it is hard to tell if that is really the cause. You may find it difficult to accurately assess the situation after asking your child to describe his or her symptoms because your child may not know how to explain what he or she is feeling and may be too fussy to respond at all. Even if you can pin down what is bothering your child, food allergy symptoms are similar to those caused by asthma, environmental allergies, and food intolerances (think lactose intolerance). Luckily, there are a few telltale signs that it might be a food allergy.
