While these are some symptoms of asthma in children, your child's doctor should evaluate any illness that complicates your child's breathing. Many pediatricians use terms like "reactive airways disease" or bronchiolitis when describing episodes of wheezing with shortness of breath or cough in infants and toddlers (even though these illnesses usually respond to asthma medications). Tests to confirm asthma may not be accurate until after age
Asthma is the leading cause of chronic illness in children. It affects about 7 million children in the United States and, for unknown reasons, is steadily increasing. Asthma can begin at any age (even in the very elderly), but most children have their first symptoms by age 5.
No one really knows the exact reasons why more and more children are developing asthma. Some experts suggest that children spend too much time indoors and are exposed to more and more dust, air pollution, and secondhand smoke. Some suspect that children are not exposed to enough childhood illnesses to direct the attention of their immune system to bacteria and viruses.
