Foods and stinging insects are well known causes of Anaphlaxis but the most common is drugs. Latex rubber has been recognised as a cause of serious allergic reactions, including death. Any food especially egg, fish and milk in children may result in a severe allergic reaction, most of which are quickly outgrown but, for reasons not understood, a nut allergy, if severe, remains lifelong.
Peanuts cause more allergic problems than any other nuts.
Some people may have multiple nut allergic problems, but not be peanut allergic. Other food allergies are often present simultaneously with nut allergies. Clinically the initial signs at the beginning of an anaphylactic reaction include a feeling of warmth, itchy mouth and throat, and skin. In children under the age of 5, vomiting often occurs. There is a feeling of doom and faintness, generally gross local swelling of lips and face and generalised itchy urticarial rash.
