Common Allergens In People

Probably the most common source of allergic reactions
in most people is in their food. Whether its
shellfish, or mushrooms, or even something mundane
like a vegetable, allergic reactions from food are
quite common.

And if you’ve been stung by an insect and notice
excessive swelling from the locality of the bite, then
you’ve got an allergic reaction from that bite.

There are even cases of extreme allergic reactions to
bee stings, resulting in anaphylactic reactions.
Chemicals and medicine also fall into the category of
being a common source of allergic reactions.

If you’ve got to have antibiotics as prescribed by the
doctor, make sure that your body doesn’t have an
allergy to materials in your medicine.

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.
