How to Classify Asthma

Asthma is a chronic obtrusive inflammatory disease of the airways. Though clinically it is classified on the basis of frequency of symptoms and severity of the attack, the subtypes of this classification is still not known yet. Today this is the major factor of the research in the field of asthma. Even though the symptoms might be same, the treatment differs and with the determination of this sub groups it will greatly help in its cure.

It is also classify on the basis of forced expiratory value in 1 second (FEV1) and peak expiratory flow rate. Similarly it can be classified into extrinsic and intrinsic which is based on whether the symptoms are a result of allergens or not. Extrinsic or atopic asthma is an attack triggered by allergens whereas if the attack is not triggered by allergens then it is defined as intrinsic or non atopic asthma.
Talking about classification of asthma, we might need to know what brittle asthma is.
Brittle asthma includes two types of asthma both severe and recurring.
*Type 1 refers to the kind of asthma with wide peak flow variability inspite of intense and high medications.
*Type 2 refers to the background well-controlled asthma with sudden and severe exacerbations.
Another type is Status asthmaticus which refers to an acute exacerbation of asthma that does not respond to standard treatment. One of the causes of asthma that resulted in fatal condition in this type is the use of beta blocker medications.
Asthma as a result of workplace exposures, excessive work strain and acute pressure is defined as Occupational asthma. However, at present most of the cases of occupational asthma are not reported and in some cases are not even recognized..
Though these common and major types of asthma are very active in research field, many more kinds might be detected in future with the expertise.
