If your child develops a rash, vomiting, swelling, hives, wheezing, or other symptoms shortly after eating certain foods, it may indicate a food allergy. Keeping a food and symptom diary can help identify possible triggers, but a diagnosis should be made by a pediatrician or allergy specialist.

Your doctor may recommend tests such as a skin prick test, specific IgE blood test, or, in some cases, a medically supervised oral food challenge, which is considered the most accurate way to confirm a food allergy. Seek emergency medical care immediately if your child has difficulty breathing, swelling of the face or throat, repeated vomiting, or becomes unusually sleepy after eating, as these may be signs of a severe allergic reaction.
