Understanding COPD(chronic obstructive pulmonary disease)
COPD is a disease that affects the lungs, causing reduced airflow, which makes it hard to breathe. It is also progressive, which means it worsens over time. COPD can include emphysema, chronic bronchitis, or both. Roughly 15 million adults in the U.S. have been diagnosed with COPD, while millions more who have it may not even know it.
Cigarette smoking is the most common cause of COPD, but there are also other potential causes, including long-term exposure to:
- Secondhand cigarette smoke
- Air pollutants / chemical fumes in the home and workplace
How does COPD affect the lungs?
First, it is important to understand how the lungs work. When we breathe, air travels down the windpipe into the lungs and then into smaller airways or bronchial tubes. At the ends of these tubes, there are bunches of tiny elastic air sacs called alveoli, which expand when we breathe air in and deflate when we breathe out. This is how the body transfers oxygen into the bloodstream and then discharges carbon dioxide waste.
COPD disrupts the airflow in and out of your lungs and reduces your lung function due to one or more of the following:
- Airways and air sacs lose elasticity.
- The walls separating the air sacs become permanently damaged.
- The walls of the airways become thick and inflamed.
- The airways make more mucus than usual, which can clog them.
Once-daily ANORO helps keep airways open to prevent COPD symptoms and helps you breathe better for a full 24 hours. Your results may vary.
Symptoms include wheezing, cough, chest tightness, and shortness of breath.
If you have COPD, ask your doctor if ANORO could be right for you.
