Food Allergy And Anaphylaxis
Food Allergy and Anaphylaxis in an Irritating Nutshell
A person will never know if they are allergic to a certain type of food
unless they have eaten the food allergen itself. It takes a certain
amount of food for the reaction to take place and trigger a symptom.
Food allergy and anaphylaxis are closely related, but they have their
own defining differences that will be discussed as you read on.
Plus, a person can also develop allergic reactions to foods that are
closely related to the original food allergy he or she has. Say, an
allergy to oysters can also lead to an allergic reaction when the
person eats shrimp, crabs, or fish.
In food allergy, the individualís immune system reacts in two ways. The
body may respond through the use of mast cells. These mast cells can
come about at just any part of the human body but its favorite spots
make itself known to the world is in the throat, lungs, eyes, skin, and
especially the organs of the gastrointestinal system. The other type of
response is through the bodyís release of immunoglobulin E antibodies
that travel through the blood system. It then eventually causes the
discharge of the body chemical histamine which then causes the
activation of allergic reactions in the common body sites previously
On the other hand, anaphylaxis is derived form the Greek words ana and
phylaxis, which subsequently means back and protection. It is the
abrupt allergic response that is much more intense than the common
allergy which can be lethal to the sufferer. Chief causes of
anaphylaxis include insect stings, skin contact to latex, medications,
and food. Anaphylaxis may also be idiopathically caused or, in lay
manís terms, unknown causes.
Like in food allergy, anaphylaxis involves the reaction of the
different body sites; the only difference is the intensity of the
response and only a small amount of the allergen is needed for the
reaction to take place. The time span before signs and symptoms become
evident ranges from within a few seconds up to a few hours after
Anaphylaxis can come about following the intake of food, skin contact,
or even as simple as inhalation of the food aroma. The life threatening
type of anaphylaxis is called anaphylactic shock. In anaphylactic
shock, only a tiny amount of the food allergen is needed to cause death
to the sufferer within moments of exposure.
Individuals who are in danger of undergoing an anaphylactic reaction
are those who have a history of allergy to food, asthma, and eczema.
They are more likely to experience an anaphylactic response that can be
fatal. Another population group who are also at risk of anaphylaxis,
through the evidences of current studies that have been conducted, is
teenagers who are afflicted with a certain type of food allergy. This
is due to the fact that teenagers have frequent tendencies to eat out,
are daring and experimental in their endeavors, and are more likely to
fail to identify symptoms of anaphylactic reaction. Moreover, teenagers
have tendencies to forget to carry with them essential medications
which can either be caused by self-consciousness common to their age
Symptoms of anaphylaxis may be similar to that of food allergies.
Basically, an incident of anaphylaxis initially starts with an itchy or
irritating sensation, and some individuals experience a metallic
after-taste. Anaphylactic symptoms may also include hot flashes or
sudden warm feeling, inflammation of the throat and oral cavity, hives,
dyspnea or labored breathing, low blood pressure, diarrhea, gastric
irritations, and fainting or loss of consciousness.
Furthermore, there are cases wherein the symptoms fade away for a
moment but then come back within a few hours; this incidence is known
as biphasic reaction.
To prevent food allergy and anaphylactic reactions, careful scrutiny of
food labels, diet modifications, specific instructions in food orders
in restaurants, and certain medications can be of great help in
reducing the incidence of any type of reaction. Moreover, a
consultation to the physician is advisable for an efficient management
plan and if allergies seem to run in families because it can also be
