Some facts about Allergy
Allergies
cause a wide range of symptoms, from the common problems that everyone
has heard of such as a runny nose, nasal congestion, sneezing; watery,
itchy, red eyes; and itchy ears, to less obvious problems like a tickle
in the throat, cough, asthma, wheezing, shortness of breath, hives, eczema,
bee sting reactions, and so forth.
Allergy symptoms are caused by too much immunity. Everyone's system produces
antibodies to fight infection. An allergic person's system produces an
allergy antibody (IgE) in response to allergens. Allergens include substances
in our environment such as pollen proteins. For an allergic individual,
an allergy antibody is a fuse that ignites an allergy bomb-allergy cells
that release histamine and other natural chemicals that cause allergic
symptoms. Histamine can be released anywhere in the allergy-prone victim's
body. Histamine released in the nose causes sneezing and a runny nose;
in the lungs causes bronchial spasms or wheezing-asthma; in the skin causes
itching or hives; in the stomach causes nausea. If histamine is released
through the body, a life-threatening allergic reaction-anaphylaxis--can
be produced causing death without immediate treatment.
Some common allergies include:

and asthma symptoms activated by microscopic bugs that live in carpets,
upholstered furniture, bed linens, mattresses and box springs, animal
dander and house dust.
