What does asthma look like?
Dr Joel Ten, GP and spokesperson for the National Asthma Council Australia, explains the physical changes in a person's airways when they are having an asthma attack.
Asthma is a chronic lung condition that affects the airways (the breathing tubes that carry air into our lungs). Asthma is caused by inflammation and tightening of the thin muscle around the airways which makes it harder to breathe.
