Those who suffer from the disease of the airways are called asthmatic. This is usually a long-lasting ailment in most of the cases, though in some patients it manifests intermittently. Whatever the case may be, what is crucial to note down is that the passages that are meant to carry the air from and to the lungs are not healthy. The inner lining of these airways gets inflamed or swollen due to various reasons, obstructing the smooth functioning of the respiratory system. With the narrowing down of the air-passages the amount of air required for breathing reduces, causing extreme discomfort.


Causes Of Asthma

Allergy is the most common cause of asthma. It has been seen that almost all of the patients suffer from some or the other allergy. The common allergens are fungi, dust mites, pollens and animal proteins. Allergic reactions also develop due to the antibodies present in the blood.

Smoke of tobacco proves to be allergic to a few, while some others may suffer due to household fumes or paints. Some people suffer from hay-fever; this hay fever too can lead to development of asthma. Environmental factors are known to be responsible for increase in the number of asthma patients. Air pollution due to vehicular traffic, release of polluted air from the chemical factories are also the chief causes.

Children are the most vulnerable to asthma. The young ones or the newborn babies can get caught in the grips of this disease if they have been born with low birth weight. Passive smoking is another factor that causes asthma among the young ones.
