Overview
When your child has a tree nut allergy and eats nuts, your child's body reacts as if these nuts are trying to cause harm. It fights back by setting off an allergic reaction. A mild reaction may include a few raised, red, itchy patches of skin (called hives). A severe reaction may cause hives all over, swelling in the throat, trouble breathing, belly pain, nausea or vomiting, diarrhea, or fainting. This is called anaphylaxis (say "ANN-uh-fuh-LAK-suss"). It can be deadly.
A good way to prevent your child's allergic reaction is to avoid the foods that cause it. Tree nuts include almonds, pecans, cashews, walnuts, and other nuts.
Some of the foods that might contain tree nuts include salads, Asian dishes, baking mixes, and sauces. Flours made from tree nuts are often used in vegan and gluten-free dishes. An allergy doctor or a dietitian may be able to help you understand which foods will be okay and what to avoid. Learn what to do if your child has a reaction.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
