چکیده
Non-IgE mediated food allergies are caused by a reaction involving other components of the immune system apart from IgE antibodies. The reactions do not appear immediately after the ingestion of the food and usually relate to reactions in the gastrointestinal tract such as vomiting, bloating and diarrhoea. IgE-mediated means that IgE allergy antibodies are a cause of the allergic reaction to a food. By contrast the signs and symptoms of IgE mediated food allergy usually occur within minutes of ingestion and include hives, redness of the skin, vomiting and in more severe reactions, anaphylaxis. The mechanism of non-IgE-mediated food allergy is not well understood. Although the immune system is presumed to be involved, IgE antibodies are not associated with this condition, hence the term “non-IgE-mediated” food allergy. This term is an umbrella term for a range of gastrointestinal food allergies that affect the full length of the gut.
