Asthma - pediatric

This article discusses asthma in children. For a more general discussion about the disease, please see asthma.

Asthma is commonly seen in children. It is a leading cause of hospital stays and school absences. Children with asthma may be able to breathe normally most of the time. When they encounter a substance that can cause problems (a "trigger"), an asthma attack (exacerbation) can occur. Common asthma triggers include:

• Tobacco smoke
• Dust
• Pollen
• Exercise
• Viral infections, such as the common cold
• Animals (hair or dander)
• Chemicals in the air or in food
• Mold
• Changes in weather (most often cold weather)
• Strong emotions
• Aspirin and other medications

In recent years, there has been a worldwide increase in the number of children with asthma. This trend has been linked to environmental factors, including air pollution. However, it is important to understand that indoor triggers can play just as much of a role as outdoor triggers in bringing on an asthma attack.

Children's airways are narrower than those of adults. This means that triggers that may cause only a slight problem in an adult can create more serious problems in children. In children, an asthma attack can appear suddenly with severe symptoms. For this reason, it is important that asthma be diagnosed and treated correctly. Some children may need to take medicine every day, even when they do not have symptoms.
