Detailed explanation-1: -Asthma is a chronic, inflammatory disease in which the airways become sensitive to allergens (any substance that triggers an allergic reaction). Several things happen to the airways when a child is exposed to certain triggers: the lining of the airways become swollen and inflamed.

Detailed explanation-2: -Asthma is an inflammatory disorder of profound heterogeneity with strong genetic and environmental components. Local airway susceptibility factors together with allergen-specific immune polarisation interact both in the induction and subsequent expression of the disease phenotype.

Detailed explanation-3: -Sinus infections, allergies, pollen, breathing in some chemicals, and acid reflux can also trigger attacks. Physical exercise; some medicines; bad weather, such as thunderstorms or high humidity; breathing in cold, dry air; and some foods, food additives, and fragrances can also trigger an asthma attack.
