Food Allergy And Anaphylaxis
|
|
Untill they have eaten the
food allergen itself, anybody can know if they are sensitive to a certain
type of food. A certain amount has to be ingested for the alacrity to
take place and trigger a symptom.
Food allergy and anaphylaxis are closely related, but each has particular
specificities.
Moreover a patient can also develop reactions to foods that are closely
related to the original food allergy he or she has.
For example, an allergy to oysters can lead to an allergic reaction when
the person eats other seafoods.

In food allergy, the
individual’s 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 forge 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 body’s release of immunoglobulin E antibodies that drive
through the blood system. It then eventually causes the action of the body
chemical histamine, which hence causes the activation of allergic reactions
in the common body sites previously mentioned.
On the other hand,
anaphylaxis is derived from the Greek inflection ana and phylaxis, which
mean back and protection. Main causes of anaphylaxis include insect stings,
long contact to latex, medications, and food. Anaphylaxis may also have
unknown causes.
Anaphylaxis is very similar
to food allergy; the only difference is the small amount of the allergens
required for the reaction to take place. The time from early signs to
symptoms can be a few seconds up to a few hours for allergen exposure.
Basically, an attack of anaphylaxis initially starts with an itchy or
irritating sensation, and some individuals have a metallic after-taste. Then
come other symptoms like hot flashes or sweating, inflammation of the
throat, low blood pressure, diarrhea, gastric irritations, fainting or loss
of consciousness.
There are cases where the
symptoms appear first but then come back within a few hours; this is known
as biphasic reaction.
Anaphylaxis can come after intake of food, skin contact, or acts as smooth
as inhalation of food aroma. Anaphylactic shock can be life threatening and
anaphylactic shake only needs a tiny amount of food allergens is to cause
death to the sufferer within moments of exposure.
Countries in danger are the
ones where most of the population has allergies to food, asthma, and eczema.
An anaphylactic functioning can be fatal there.
Studies show that an increasing population group has anaphylaxis with
unknown cause and also that teenagers are more and more afflicted with a
certain type of food allergy.
The teenager’s habits like eating out, daring and experimenting, are more
likely to get symptoms of anaphylactic reaction.
To prevent from food allergy
and anaphylactic reactions, it is important to carefully study food labels,
modify diet, five specific instructions when ordering in restaurants.
Certain medications can be a good help in reducing the symptoms during a
reaction. The family physician might give good advises even more valuable if
there is hereditary causes.
