Asthma is a breathing disorder that affects the airways. Airways are the tubes that carry air in and out of the lungs. The airways are surrounded by smooth muscle that tightens up and relaxes as you breathe.

Asthma causes the inside walls of the airways to get swollen (inflamed). Swollen airways tend to be very sensitive, and they may react strongly to allergens and irritants (like dust and cigarette smoke). When the airways react, the muscles tighten up (bronchospasm). The combination of inflammation and bronchospasm causes airways to get narrower and less air flows in and out of the lungs. Cells in the airway may also make more mucus than usual. This extra mucus narrows the airway, which makes it harder to breathe.
