Question

What is the cause of asthma?

Answer 1

Asthma:

1. It is a disease in which breathing is difficult and it also triggers coughing.
2. In this disease, the airways get narrower and they get swelled up which may also lead to extra mucus.
3. Asthma develops when bronchi and bronchioles become inflamed, causing breathing problems and wheezing.
4. It is triggered by irritants or allergens that cause mast cells to produce an allergic reaction.
