Are Allergies Passed From Generation to
Almost everyone will suffer from allergy at
some point in their lives. Allergies are known for their irritating symptoms
and their life-threatening complications that affect breathing. For years,
numerous medical studies have been conducted to find out the cause of
allergies. Some researchers have suggested that environmental factors can
cause allergies. Others have associated early exposure to specific allergens
as the cause of allergies showing up later in life. While there are
researchers who say that genetics can play a big role in the development of
allergies. The question often asked is " Are my allergies Inherited"
In a study conducted by the Mt. Sinai School of Medicine, researchers tested
58 pairs of twins for peanut allergies, which is one of the most common
types of allergies affecting children and adults around the globe. In almost
every pair of twins, one had a convincing history of peanut allergy. The
participants were also observed for any sign and symptom of allergic
reaction 60 minutes after they’ve eaten peanuts. The results of this
experiment showed that almost 70 percent of the participants shared the
allergy. Another interesting thing they found out was that the allergic
symptoms varied from one twin to the other.
Because of the results of this study, Mt. Sinai School of Medicine claims
that genetics accounts for 80 percent of the risk for peanut allergy. A
group of British researchers has done a similar study on the most common
types of food allergies and they say that, considering genetic and
environmental factors, allergies are inherited 80 to 85 percent of the time.
They also say that there is an almost 20 percent difference when genetic
factors are disregarded.
But food allergy is not the only type of allergy that affects people.
Asthma, for example, is a common type of allergy that is often severe and
causes problems in airway and breathing. Asthma attacks can be triggered by
numerous factors like animal hair, mold, dust, pollen, cigarette smoke,
temperature and weather changes, air pollution and physical fatigue.
Researchers used to think that environmental factors solely caused asthma
attacks, but they are now considering the role genetics may play in this
A study that took place in Arizona tested 344 families to determine if there
is a link between genetics and asthma. The results of the study confirmed
the researchers’ hypothesis that asthma can be passed from generation to
generation. From families where neither parents had a history of asthma,
only five percent of children suffered from asthma. In families where either
the mother or the father suffered from asthma, 20 percent of children
suffered from the same condition too. And in families where both of the
parents had a history of asthma, nearly 70 percent of the children had
asthma as well. The results show that there is a strong link between allergy
But as reported by researchers at the Vrije Universiteit in Amsterdam,
genetics is not the only factor that determines whether a person will
develop allergies or not. Allergies typically appear due to a combination of
two or more causative agents. There are certain cases wherein environmental
causes contribute more heavily to the development of an allergy, and there
are other cases wherein genetics is a bigger determinant compared to other
Personally what we see in our customers is
that both genetics and environmental issues play a role in their allergies.
For the time being we will concentrate on helping them clean up
