Asthma is common in kids and teens, and tends to run in families. It can be mild or so severe that it gets in the way of daily activities.
With medicine and the right care plan, asthma symptoms can be managed so that kids and teens can do just about anything they want to do.
What Causes Asthma?
No one knows exactly why some people develop asthma. Experts think it might be a combination of environmental factors and genes.
People with asthma may have a parent or other close relative with asthma. Those who are overweight may be more likely to have it.
