Understanding childhood asthma
Asthma is the most common chronic illness in children. One out of every 10 children has asthma and this number continues to rise. Asthma is one of the main reasons for school absences and the most frequent cause for hospitalization. However, good understanding of the causes and treatment of asthma can help to reduce the effect of asthma on children and their families.
What causes asthma in children?
Asthma is a chronic condition. The symptoms of asthma are caused by inflammation (swelling and irritation) and airway constriction (tightening of the muscles around the airways) in the lungs. Children with asthma may have some or all of the following symptoms: cough, wheezing, shortness of breath, rapid breathing, and chest tightness.
These symptoms may occur daily, several times a week, or only during certain times of the year. Potential triggers include illness, dust, mold, animals, pollens, cigarette smoke or cold air. Every child is different.
How can you tell if your child has asthma?
There is no simple test to diagnose asthma. However, there are some signs that may help your child's physician in deciding if your child has asthma:
- Wheezing (a high-pitched whistling sound) when your child breathes in and out.
- Frequent cough that may be worse while asleep, with exercise, or exposure to cold air.
- Difficulty keeping up with other children during play or self-limiting exercise activity.
- Respiratory illnesses (cough and colds) that last a long time ( more than 2 weeks).
