Allergies and How They Affect The Body

If you’ve ever tried inhaling some pollen from plants,
or eating something and finding out afterwards that
you’re covered in red blotchy spots or some other
nasty effect after you eat, then you’ve experienced
firsthand the effects of Allergies.

In common usage, an allergy is an adverse reaction
toward what is called an allergen, or specifically,
the material that causes the allergic reaction.

What Happens When You Come In Contact With An
Allergen?

When you ingest something that causes an allergic
reaction in your body, the immune system is said to be
hyperactive to this material, and with that, the
immune system activates to quash what it sees as a
threat. But it’s actually not, and is quite harmless
and garners no excess bodily reaction in other people.

Once the body’s immune system releases antibodies as a
response to the allergen, it causes the release of
histamine into the bloodstream, which is what causes
you to get teary-eyed and have a runny nose or
whatnot.
