What Causes Asthma?

What Causes Asthma?
Most cases of asthma are caused by a combination of genetic and environmental
factors. Studies have revealed that asthma does run in families, making
children of asthmatic parents especially vulnerable to the condition. In addition,
children with an early history of infections and continuous exposure to secondhand
smoke are far more likely to develop the condition than other children.
