What are the signs and symptoms of a tree nut allergy?

Signs and symptoms of a tree nut allergy are those of a typical food allergy. Signs and symptoms include diarrhoea, vomiting, swelling around the mouth, face, lips, tongue, and throat, or hives or a rash on the skin. In adults, the hives or skin rash might be more apparent that in younger people. You might also have a wheeze or cough, or difficulty breathing.

The most severe consequence of eating tree nuts if you have a tree nut allergy is anaphylaxis. The signs and symptoms of anaphylaxis include a fast heart rate, low blood pressure, stress and anxiety, loss of consciousness, sweating, flushing, abdominal pain or diarrhoea, or difficulty in breathing. Anaphylaxis is life threatening if untreated and requires urgent treatment with adrenaline, usually given by an intramuscular injection (an injection into the muscle) by an EpiPen. If you have a severe allergy that is likely to trigger anaphylaxis, it is a good idea to see your doctor and get an EpiPen, and then train yourself and your friends and family in using it. You should always carry your EpiPen with you.

The signs and symptoms of a tree nut allergy can appear very quickly, often within minutes of eating the nuts.
