Overview

Asthma is a breathing disorder that affects the airways. People with this condition experience recurrent swelling and narrowing of the airways of the lungs which is associated with wheezing, shortness of breath, chest tightness, and coughing. Most affected people have episodes of symptoms ("asthma attacks") followed by symptom-free periods; however, some may experience persistent shortness of breath in between attacks.[1][2] Asthma is considered a complex or multifactorial condition that is likely due to a combination of multiple genetic, environmental, and lifestyle factors. Many people with asthma have a personal or family history of allergies, such as hay fever or eczema. Having a family member with asthma is associated with an increased risk of developing the condition.[3] Treatment generally includes various medications, both to prevent asthma attacks and to provide quick relief during an attack.[1][2]
