Asthma is one of the world’s most common chronic conditions, impacting an estimated 339 million people worldwide. But, as prevalent as asthma is, it is also a complex disease comprising a spectrum of different phenotypes. While the challenge of asthma in all its forms remains significant, severe asthma continues to be largely misunderstood and is a space where vast potential to improve treatment and outcomes remains. Severe asthma can be debilitating to those struggling with it, leaving them frustrated with their limited treatment options while attempting to regain control of their lives. Severe asthma is not “just asthma,” it can be a truly devastating and life-threatening condition.
