Asthma
Asthma attacks all age groups but often starts in childhood. It is a disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. In an individual, they may occur from hour to hour and day to day.
This condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack, the lining of the passages swell causing the airways to narrow and reducing the flow of air in and out of the lungs.
Causes of childhood asthma:
Researchers continue to learn what causes asthma. It is not entirely understood. The following things play a part:

Allergies: Some allergies are more common in people with asthma. And, allergies also tend to run in families.
Respiratory infections: Infants and young children who have some respiratory infections are more likely to have long-term lung problems.
