Asthma has a tendency to recur and get chronic. It is often observed to be a life long disease like diabetes or high blood pressure.

While understanding the causes of chronic asthma, we have to appreciate that asthma is caused by multiple factors.  It is often more than one factor responsible for the maintenance of long term or chronic asthma, such as:

-         Genetic or hereditary cause

-         Environmental factors (pollution, pollen, etc)

-         Systemic diseases

-         Mental stress

-         Allergens

One or more of the above factors lead to altered immunity which eventually leads to chronic asthma. It may be noted that the genetic tendency for asthma forms soil, leading to susceptibility to be affected by other external or internal trigger factors.
