When you have a tree nut allergy and you eat tree nuts, your 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, nausea or vomiting, or fainting. This is called anaphylaxis (say "ANN-uh-fuh-LAK-suss"). It can be deadly.
A good way to prevent an allergic reaction is to avoid the foods that cause it. Tree nuts include almonds, pecans, cashews, and walnuts. 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 might be okay and what to avoid. Learn what to do if you have a reaction.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
