Food allergies in children happen when the immune system attacks a food protein by mistake. This causes many antibodies to form, called immunoglobulin E, or IgE. These antibodies release different chemicals that the body reacts to.  

Children’s food allergies show up in different ways. A child can have hives (red, itchy patches on the skin), eczema (dry itchy rash), nausea or diarrhea. The mouth and lips may be itchy and swollen, and some children have trouble swallowing or a dry cough. A severe allergic reaction called anaphylaxis can happen. 

We know how hard food allergies can be on your child and the whole family. Our allergy and immunology specialists will create a care plan that fits your lifestyle. We work to balance your child’s safety with being able to enjoy friends, activities and school.
