Signs Of Food Allergy
Food allergy can be complicated to detect as it can easily be mistaken for food poisoning. However, there are lots of fundamental differences between food poisoning and food allergy – food poisoning is a one off occurrence that can happen from any type of food that is externally contaminated while food allergy is a persistent reaction to a particular food that results in a reaction with the immune system. But it is important to know what the signs of food allergies can be.
One can be allergic to any kind of food that their immune system fails to detect as a food and ends up classifying it under a threat. This results in the activation of the immune system to fight the entry of the food into the body. There are some foods that generally causes allergic reactions like cow's milk, eggs, fish, peanuts, tree nuts, shellfish, soy and wheat. A person can be allergic to just one or multiple foods. In many cases, some of the symptoms of food allergy can be fatal, which compel people to take extreme precautions to avoid them.
DO YOU SUFFER FROM DUST ALLERGY?
General symptoms or signs of food allergy can be itching or swelling of the mouth, tongue or lips. In some cases food allergy leads to skin reactions like eczema, hives, swelling and redness. One may look for signs like gastrointestinal symptoms such as abdominal pain, nausea, vomiting, diarrhoea. Some foods lead to allergic reactions that affect respiratory symptoms leading to runny or stuffy nose, coughing, sneezing, wheezing, difficulty in breathing etc. Some men can experience cardiovascular symptoms due to food allergy where they experience a drop in blood pressure, light-headedness, and fainting. In many cases it is important to seek immediate medical attention no matter how cautious you have been.

1.Lactose
intolerance
Lactose
intolerance,
which
is
the
most
common
allergy
also
referred
sometimes
as
dairy
intolerance,
occurs
when
your
body
fails
to
digest
lactose.
Lactose
is
present
in
milk
and
dairy
products
such
as
yoghurt
and
soft
cheese.
The
main
symptoms
of
this
food
allergy
are
diarrhoea
and
stomach
pain.
In
most
cases,
your
doctor
can
diagnose
lactose
intolerance
by
looking
at
your
symptoms
and
medical
history.
2.Gas,
cramps,
or
bloating
Once
the
food
you
are
allergic
to
reaches
your
digestive
system,
you
would
start
to
experience
signs
such
as
gas,
cramps
or
bloating.
Gas
formation
in
your
stomach
can
be
as
a
result
of
reaction
to
foods
such
as
peanuts.
Even
though
gas
formation
is
a
normal
occurrence,
you
can
differentiate
the
signs
by
noticing
sudden
formation
of
gas
and
excess
release
of
gas
due
to
bloating.
3.Nausea,
vomiting,
diarrhoea
Sometimes
the
allergic
reaction
to
food
in
your
stomach
can
cause
more
severe
symptoms
such
as
nausea,
vomiting,
diarrhoea
etc.,
which
causes
mild
to
extreme
loss
of
energy
and
body
fluids.
It
could
be
due
to
indigestion
or
non-capability
of
your
digestive
system
to
process
complex
protein
you
would
have
consumed.
4.Skin
allergy
All
of
the
symptoms
of
food
allergy
occur
within
a
few
minutes
to
an
hour
of
eating.
Hence,
you
must
be
able
to
notice
and
differentiate
skin
related
reactions
due
to
food
by
its
timing.
When
the
allergic
food
fails
to
stop
in
your
digestive
system,
allergens
are
absorbed
and
enter
the
bloodstream.
When
they
reach
the
skin,
allergens
can
induce
hives
or
eczema
causing
rashes
and
itching
on
your
skin.
5.Blood
contamination
Once
the
allergens
are
absorbed
and
enter
the
bloodstream,
it
is
difficult
to
know
how
they
react
and
affect
you.
As
the
allergens
travel
through
the
blood
vessels,
they
can
cause
light-headedness,
weakness,
rapid
heart
rate
and
anaphylaxis.
Anaphylaxis
is
a
sudden
drop
in
blood
pressure.
Anaphylactic
reactions
are
severe
even
when
they
start
off
with
mild
symptoms,
such
as
a
tingling
in
the
mouth
and
throat
or
discomfort
in
the
abdomen.
