Allergy may be major cause in the development of asthma
Asthma is rampant in global
society and affects people of all ages. It is a persistent inflammatory ailment
of the bronchial tubes that results in swelling and contraction of the nose passage.
Reports of World health organization revealed that millions of people are under
grip from asthma and huge number of fatalities occur. Bourgeoning studies
designate that asthma is developed through allergic reaction in which the
airways of the lungs become oversensitive to some indoor and environmental
pollutants. Biologists have established fast rate of asthma and the decisive
role of allergens in the development of asthma.
It is established that
the gene-environment interactions may be a major cause of asthma. In present scenario, it is heated
theme of discussion and need to generate awareness about allergy induced asthma
to grip the syndrome in social structure. Many medical scholars assert that allergy
induced asthma is prevalent in world population when an individual is hypersensitive
to certain allergen. It is predominant in young children who are more sensitive
to aeroallergens that lead to persistent asthma symptoms at later stage of their
life than children who have good immune system or resistance power.
Role
of allergy in the development of asthma:
Since ancient time, people
has recognized the asthma as a common dilemma which affects the health care
system and it is a prime source of undesirable healthcare outcomes. Asthma is characterized as a chronic
respiratory disease which is caused by reversible airway hindrance and related with
bronchial hyper sensitivity and airway swelling. Inflammation is developed
through numerous indoor and environmental factors, known as an allergen. When
these allergens attack to person, the air passages of the bronchus and lungs engorge
and full of mucus. As a result, muscles within the bronchial tubules contract and
create narrowing of the airways. In this condition, patient unable breathe from
the lungs smoothly, have recurring periods of wheezing, chest tautness, and
coughing. Allergy has major role in developing ailment of asthma. Exposure to the
allergens may result into the pain or swelling in the respiratory system and
leads to breathlessness. Presently, environment is highly polluted, therefore
there are increased cases of allergy induced asthma.
Causes:
Plentiful researches have
demonstrated that paediatric asthma is developed due to exposure of young
children to common allergens such as contaminated foods, pets and environment. Allergic
reaction greatly affects the lungs and airways and causes asthma symptoms. The main
aeroallergens are sensitized are house dust mite (HDM), furred pets basically cat
and dog, cockroach, mold, and rodent allergens. The allergen, contained in
their droppings and transmitted in dust can prompt reaction at concentrations
of only a few μg of allergen per gram of dust, far below normal concentrations
found in homes. House dust mites and other allergens was the main carrier of
allergic reaction that can lead to symptoms of asthma. Usually, mites may get
healthy environment to grow in mattresses, box springs and pillows therefore
these can attack easily on patent’s body.
Another major
allergen that causes asthma is through animals. Cat allergen is considered to
be the most dangerous of the pet allergens that is normally found in dust
samples where a cat resides. Medical scholars investigated this factor and
demonstrated that cat allergen exposure is coupled with the development of
sensitivity and asthma. Mouse allergen
has also vital role in the developing asthma. Other allergens like molds that
can easily be scattered in dust, wood, paper, food and plants can cause asthma.
They multiply at faster rate in humid environment. Allergy disease due to molds
is caused by Alternaria, Aspergillus, Cladosporium and Penicillium spp. The
major risk factor of moulds is the IgE-mediated sensitization.
Medical reports have
confirmed the exposure to tobacco smoke via active smoking may cause lung
disease. Especially children are more prone to environmental tobacco smoke in
both prenatal and postnatal period when mother excessively smoke. This allergen
deteriorates lung function and child show the symptoms of respiratory
irritation, for example, cough, excess phlegm and breathe with difficulty. Genetic
makeup of humans has major role in vulnerability to asthma. Clinical
manifestation of Asthma is mainly dependent on complex interplay between
genetic predisposition and environmental factors.
Treatment
and prevention:
Asthma is preventable
disease if appropriate diagnostic methods are used. It depends on the age of a
person. Young children do not respond in positive way in the diagnosis process therefore
physicians study the patient and family medical history to investigate the
causes of asthma. Adults are diagnosed through a series of breathing capacity
tests to find out the extent of asthma. In normal course, doctors do not use
allergy test to determine the condition of asthma. Medical studies have
represented that eliminating persistent allergens are effectual method to
assuage allergy and asthma, but these cannot avert clinical symptoms of asthma.
There are number of
medicines prescribed by the physician to treat allergy induced asthma which
include steroids and inhalers. Tablets are often given to control allergic
reactions which lessen the chances of developing asthma. It is highly suggested
that treatment must be done under the supervision of certified doctor. Therapeutic
technique such as immunotherapy is used in treating allergy induced asthma
which involves injections of allergen extract into allergic patients. Immunotherapy
is a systematic procedure of immune modulation to control the symptomatic
condition of hypersensitivity reaction developed through IgE antibodies. But immunotherapy
has some adverse impacts on the patient such as gastro intestinal disorder which
limits its application.
The treatment of
asthma is long-term process and some patient have to take medication whole life.
It can be debated that numerous allergens like tobacco smoke and pets, food may
trigger respiratory illnesses. But scientists do not have sufficient evidence
to confirm that allergens and contaminants can decrease respiratory illnesses.
The best possible way is to lessen the damaging effects from allergens,
especially for sensitized individuals.
To bind up important
details, it is well identified among world populace that asthma disease is a
national health concern which spreads due to numerous allergens. Lung disease is
predominant at great pace in developed countries which had major roots in
allergic reaction. It has damaging impacts on the health of the affected
individual, as well as society. There
is a direct link between allergies and asthma but opponents debated that other
condition also leads to asthma and people have wrong conception that allergens
are the causes of developing asthma.
