What Part of the Body Controls Your Allergies?

Exposure to new allergens can also bring on allergic symptoms. It's very common for me to hear people say, "I didn't have any allergies at all until I moved here." They may be referring to a move from another area of the country where there are different pollens present, or just a move across town, perhaps to a home with different environmental allergens present. Either way, these people probably already had a genetic tendency toward allergies, often called "atopy" or being "atopic" by those in the medical field. Sometimes atopy is associated with an "allergic triad", which is:

Asthma
Dermatitis (Allergic Skin Conditions)
Rhinitis (Hay Fever)
