The Causes of Asthma
Today there is always a question of why do some people have asthma and why is it more common in the western countries.
The cause of asthma are very complicated.
At times during our lives, the things that we are exposed that may develop into allergies and contributing factors in the environment such as pollution that can determine whether these genes and allergies will cause asthma.
Although asthma is not contagious and cannot develop it through contact with another person, you can inherit the asthma tendency from your parents.
If a parent is a smoker, then a child is twice as likely to develop asthma than children of non-smoking parents.
Children whose mothers smoked during pregnancy have high chances of developing the disease because they were born with smaller airways. During an asthma attack, the patient’s airways become irritated, narrowing and constricting by restricting airflow that result to difficult in breathing.
The “westernized” lifestyle and the environment in developed countries has a lot to do with the chances of whether a person will develop asthma or not.
These factors include pollution, allergies to house dust mites, cats, dogs, and molds.
Ironically, it seems that childhood infections and exposure to substances from bacteria in a dirty environment, assuming such an environment doesn’t kill you, seems to build up a protection against allergies and resistance to asthma.
Allergies are the cause of almost all asthma in young people, meaning that the patient has both inherited genes that have a tendency towards asthma and have been exposed to allergy – producing things in their environment. Both the allergies and the genes are the causes for developing asthma, because if either of them were not present then no asthma would develop.
At a Glance … Asthma – Causes
It is important to distinguish between causes and triggers of asthma.
o A cause is something without which the effect of having asthma will not happen. Without a cause a patient would not be asthmatic.
o Common causes of asthma include a family history of asthma, allergies and exposure to certain infections at childhood.
