WHY Consider Participating? 

Needing steroid burst (like prednisone) is a warning sign
If you’ve needed an oral steroid burst for an asthma flare, it often means asthma control could be improved. After one flare, the chance of more flares can be higher—especially if nothing changes.

Knowing your baseline lung function matters
A breathing test gives you a baseline “lung number,” similar to checking blood pressure, cholesterol, or blood sugar. If you have asthma, lung function is part of long-term health—and it’s helpful to know where you’re starting.

Steroid bursts affect the whole body
Over time, repeated steroid bursts are linked with higher chances of issues like high blood pressure, high blood sugar (diabetes), weight gain, bone thinning (osteoporosis), and infections. That’s why doctors try to keep steroid use as low and as rare as possible.

Steroid bursts add up over the years
Steroids can be lifesaving when needed—but they aren’t like an over-the-counter pain pill that simply “wears off.” Each course can add a bit of wear and tear, and those effects may accumulate.

Asthma attacks can slowly reduce lung function
Lungs naturally change with age, but repeated asthma attacks can speed that process up. Preventing flare-ups is just as important as treating them.

Airway changes can be hard to undo
Years of inflammation can lead to airway changes (a bit like scarring). Treatments can improve symptoms and breathing, but some structural changes aren’t always fully reversible—another reason to step in early.
