Allergies (Type I Hypersensitivity) are essentially a malfunction of our immune system that triggers our body to become hypersensitized and react immunologically to usually non-immunogenic substances. The substances that cause our bodies to become this way are called allergens. In 1906, Viennese pediatrician, Clemens von Pirquet, first coined the term allergies? After he observed that certain evidence of his patients might have been a reaction to outside allergens, like dust, pollen, or certain foods.

Our immune system is a well-trained and trained bio-weapon that protects our bodies from harmful substances. Its mechanics is so wonderful that it can identify and destroy many foreign attackers. However, as dazzling as our immune system is, it makes mess ups infrequently. And so we have allergies, which, as we discussed, results from a hypersensitive immune system.The hypersensitized immunity mechanism misidentifies an otherwise harmless substance as harmful, and then attacks the substance with a degree of viciousness that is greater than required. As a result, we experience problems that can range between mildly inconvenient to uncomfortable to total failure of important organs of the body.How will the immune mechanism go into a hypersensitized state? There are really many concepts on this. Some schools premise that allergies are virtually always caused by protein. Certain folks have faulty genetic codes so that their lymphocytes or the white blood cells ( the stuff that your immune mechanism is made of) are unable to property tell the difference between the threatening and the non-threatening proteins. So, as an example, when you ingest protein from shellfish, your lymphocytes think the substance is making an attempt to invade the body. As a consequence, they produce large amounts of antibodies which attach themselves to mast cells and basophils across the body. This is thought of as the sensitizing exposure and this is the very reason why you suddenly develop allergies.
