Causes of asthma
Asthma is a condition that can be inherited, because there are certain genes that are responsible for its occurrence. Furthermore, it can be triggered by certain environmental and chemical factors. The most common causes for the occurrence of asthma are common cold, flu, pollens, allergies to food or to certain medicines, and dust mites. Asthma may also be triggered by dust and cigarette smokes, as well as by the exercises practiced in dry and cold air. In case when a person is exposed to some of the above-mentioned causes, the body’s immune system secretes the antibodies and histamines, which can lead to the inflammation of the airways.
Asthma attack is also known as asthma exacerbation. It is induced by the inflammation of the bronchial tubes, which become narrow. The bronchial tubes may also become clogged when the inflamed tissue produces thick and sticky mucus. When this mucus builds up in the lungs, the person has problems with breathing. Furthermore, the airways become constricted because of the tightened muscles around them.
