What causes Allergies?

Causes: Allergies: There are many causes of respiratory allergies and allergens can come from many sources. Common respiratory allergies are due to the inhaling of allergens such as dust, pollen, mold spores, animal dander, or cockroach or dust mite droppings.

Inhaled allergens cause a respiratory reaction, such as sneezing and runny nose. Other types of allergies, such as food, drug, and insect sting allergies can also produce respiratory allergic symptoms. These can be severe and include shortness of breath and swelling of the throat.
Article excerpts about the causes of Allergies:
Normally, the immune system functions as the body's defense against invading agents such as bacteria and viruses. In most allergic reactions, however, the immune system is responding to a false alarm. When an allergic person first comes into contact with an allergen, the immune system treats the allergen as an invader and mobilizes to attack. The immune system does this by generating large amounts of a type of antibody (a disease-fighting protein) called immunoglobin E, or IgE. Each IgE antibody is specific for one particular allergenic (allergy-producing) substance. In the case of pollen allergy, the antibody is specific for each type of pollen: one type of antibody may be produced to react against oak pollen and another against ragweed pollen, for example.
