About Allergies

Allergies start with exposure to an allergen that the body flags it as an invader. It could be to an environmental or food substance that has been previously tolerated but, during another particular exposure, the immune system studies the allergen and flags it as a threat. It readies itself for the next exposure by developing antibodies, special cells designed to detect it. You are now "sensitized" to the allergen. With subsequent exposures your body creates an allergic response.

Allergy tends to be hereditary. While specific allergies are not inherited, a tendency toward having allergies is. A family history of atopy (genetic tendency to develop allergic diseases such as allergic rhinitis, asthma and atopic dermatitis (eczema) can make children more susceptible to allergies. It is both possible to outgrow and acquire allergy at various points in one’s lifetime, with allergies most frequently appearing after the age of 5 and rarely after the age of 60.

No age is too young if a child is exhibiting symptoms of allergy. It is not generally practiced however, to test for allergens in which there has been no exposure yet, for the risk of obtaining false positive results to that allergen.
