ALLERGY

What is an Allergy?
The topic of allergies has become routine in our lives, and certainly most everyone has an idea of what an allergy is. Allergies are so common a subject in fact, it seems acceptable to discuss your allergies at a cocktail party with strangers.
How do Allergies Start?
The allergic person can make allergic antibodies, or IgE, against a variety of allergens, including pollens, molds, animal danders, dust mites, foods, venoms and medications. This occurs through a process called sensitization, where a person’s immune system is exposed to enough of the allergen to make the body produce allergic antibodies to that substance.
When and Why do People Develop Allergies?
It is unknown why some people develop allergies and some don’t. Allergies seem to run in families, and in some cases family members can share allergies to specific foods or medications. It appears that the allergic response was once meant to protect the body against parasitic infections, although now seems to be an abnormal response to non-infectious triggers.
