Asthma is a chronic disease of the airways in the lungs. The two main components of asthma are airway constriction and inflammation. Together, constriction and inflammation result in narrowing of the airways in the lungs, which results in symptoms such as wheezing, coughing, chest tightness, and shortness of breath. It's also important to remember that some days, you may not even experience any symptoms at all. But your asthma is still with you. That's why it's essential to continue treating your asthma, with daily preventative medication, even on days you feel well.

One way of helping to manage your asthma is through education. In this section we have provided useful information about your asthma so you'll begin to understand how you can help treat it. Here's what you'll find:
