What is asthma?

Asthma is a long-term condition affecting your airways — the small tubes that carry air in and out of your lungs, making them more sensitive and inflamed.1,2

Everyone’s airways are ringed with a type of muscle, and like any other muscle it can tighten.1

This tightening is what happens during an asthma attack (also called an exacerbation), narrowing the space for air to get through and making it hard to breathe.1

The lining of your airways can also become inflamed and produce mucus, narrowing the space even more.1
