IF YOU HAVE ASTHMA,
YOU ARE NOT ALONE—
ABOUT 25 MILLION AMERICANS
SUFFER FROM THIS DISEASE.

Normally, the airways of your lungs are open, allowing the air you breathe to move in and out easily. When you have asthma, exposure to inhaled irritants, or triggers, can cause the walls of your airways to become inflamed and the muscles around the airways to tighten up. This makes your airways narrower, leaving less room for air to flow.
