Asthma is now considered a heterogeneous disease, meaning every asthmatic is different and cannot be treated the same. Because of this, researchers found it useful to break asthma into subgroups (also called subtypes or endotypes).
Subgroups are nice because they allow researchers to create guidelines tailored to each specific asthmatic. This makes it easier for physicians to help their asthmatic patients gain better control of their disease.
Here are some examples of subgroups:
1. Allergic Asthma. These patients develop adverse reactions to common allergens, such as dust mites, cockroach urine, pollen, mold, fungus, and animal dander. Treatment must focus on preventing and controlling both the asthma and allergy component, which can make it complicated to obtain optimal asthma control.
2. Exercise Induced Bronchospasm. Their air passages spasm and narrow after exercising, resulting in shortness of breath and coughing. Many respond well to a pre-treatment of albuterol prior to exercising. Others respond well to daily inhaled corticosteroid th
