Allergens are generally harmless substances that can cause irritation to oversensitive immune systems to certain people thus an allergic reaction happens. There are numerous types of allergies that people have but there are really common types of allergies that affect almost more than half of the population in the US alone. There are allergens that are said to be the main reason for nearly all of the symptoms of an allergy.
Common Allergies
Pollen
Pollens are powdery
substances that are produced by grasses, trees, weeds and other types of plant
that play a big role in their reproduction. They also happen to be the most
common types of allergen. People who are allergic to pollen often show symptoms
such as frequent sneezing, runny nose, itchiness in the eyes and nose and
frequently coughing because of itchiness in the throat. Because these pollens
are so small and light, people allergic to it often experience attacks on windy
days and usually in the morning. Treatments for this are allergy shots,
medication and recommendation of staying indoors as much as possible during
times of peak pollen seasons.
More Common Allergies
Food
According to health
experts there is a rise in people affected with food allergy around the world,
in the US alone there is an estimated 4% of the population who suffer from this
type of allergy. The ones who are highly at risk are children particularly
those who aged 3 years and below. Foods that commonly cause allergies are peanuts,
sea foods such as fish and shellfish, nuts such as cashews, walnuts and almonds
and peanuts and milk and eggs. Nausea and vomiting are the most common symptoms
of mild food allergy attacks but for those who are highly sensitive to these
foods can undergo anaphylactic shock this is why people who have severe food
allergies have with them epinephrine injections all the time so that in case of
attacks they can be treated immediately.
Dust Mites
These microscopic
creatures seem to not exist at all because we can’t see them with the naked eye
but they are everywhere—homes, schools, office, etc. They eat fungi, bacteria
and dead skin cells. People are not really allergic to dust mites but to the
proteins that are found in their waste products. Dust mites do not live in
high-altitude places and they are commonly found in bed sheets, pillows and
carpets which are the reasons why if you are allergic to dust, it is important
to regularly clean your place.
Animal Dander
As much as we love our
pets and animals, they too can actually cause allergies to many people. People
who are allergic to animal dander are so common that one out of allergic people
is affected with it. Most people think that the reason why we are allergic to
animals are because of their hair but even hairless pets can cause allergies
because it is not what’s in their hair rather it is what’s in their dander that
contains proteins causing the allergies. These microscopic substances are
carried in the air and are inhaled by humans.
Although there are available allergy shots and medications to fight off these allergic reactions, it would be best to avoid the things that you know are allergic to. For those who are not sure if they are or are not, consult an allergist to find out to which substances you are allergic to.
