An Allergy is a hypersensitivity to foreign substances which are normally harmless but which produce a violent reaction in the allergy sufferer. Allergies are generally the body’s effort to eliminate something it considers unsuitable. Typical allergic reactions are hay fever, migraine, asthma, allergic rhinitis, digestive disturbances, coeliac disease, conjunctivitis, urticaria, eczema, drowsiness, CFS, hyperactivity in children, tinnitus,
recurrent sinusitis and ear infections. In a few people, the histamine (anaphylactic) reaction can cause muscle cramps, disorientation, unconsciousness, and death from shock or suffocation.
Types
There are different types of Allergies, the most common being type1. When an allergen encounters cells capable of antibody formation, they then form IgE antibodies, which bind to the surface of other cells, called mast cells and basophils. In response to the attachment those cells release chemicals, called mediators of anaphylaxis, among them histamine. Those chemicals cause allergic reactions such as swelling or the secretion
of mucus.
