Some conditions may share risk factors with asthma. Other conditions may contribute to the development of asthma. Still others may make asthma harder to diagnose or treat. It’s important to understand conditions related to asthma to get proper treatment and better manage your overall health. When someone has more than one health condition at the same time, the conditions are known as comorbidities.
