November is COPD Awareness Month. Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of death in the U.S. behind cancer and heart disease. According to the American Lung Association (www.lung.org), the medical cost of COPD is $24.0 billion each year among adults 45 years of age and older.
COPD manifests slowly over a period of years. Initially the symptoms are often undiscernible. Eventually symptoms develop and can include wheezing, shortness of breath, a chronic cough that produces phlegm, and a slow progressive shortness of breath. Often this increase of breathlessness is blamed on aging – this is a mistake. Symptoms begin to show in the late stages of the disease, so as soon as you notice any of these symptoms you should call your doctor.
COPD includes chronic bronchitis and emphysema.
Chronic Bronchitis
Bronchitis is inflammation of large and medium-sized airways in the lungs. It can cause a cough that often brings up mucus, wheezing, shortness of breath, chest discomfort and a low fever. It becomes chronic when a cough lasts for three months or more per year. Chronic bronchitis is a long-term condition that keeps coming back or never completely goes away.
Nearly 10 million people in the United States have a diagnosis of chronic bronchitis. The majority of these people are between 44 and 65 years of age. According to the American Lung Association, women are more than twice as likely as men to be diagnosed with chronic bronchitis.
Emphysema
In emphysema it is the tiny air sacs at the end of the airways in the lungs that are damaged. When these sacs are damaged they become larger and are not able to move as much oxygen into the blood. After these air sacs are destroyed, they cannot be replaced.
More than 4 million Americans have emphysema, which is most common among adults age 65 and older. Emphysema claims more than 9,000 lives each year.
Causes
The most significant predictor of getting COPD is a history of smoking. Other factors may include a genetic disposition. In about 1% of COPD cases, the cause is a genetic disorder that causes low levels of a protein called alpha-1 antitrypsin. This protein is made in the liver and secreted into the bloodstream to help protect the lungs. Another cause includes long-term exposure to dusts and chemicals in the workplace and other environments.
What can be done to alleviate symptoms?
Once you have COPD it is not reversible – but there are lifestyle changes that can help to better manage the disease.
The first and most important thing you can do to alleviate symptoms of COPD is–if you smoke–to stop smoking. The second goal on the list is to increase your exercise and movement. These two tasks are not easy to accomplish, but they are both critical to improving your life with COPD.
A comprehensive pulmonary rehabilitation program for people with moderate to severe COPD often meets three times a week for eight weeks. Typically the program focus on endurance exercises to build leg strength, such as walking or stationary cycling. There are often programs available through a hospital on an outpatient basis. Several studies show that participants in pulmonary rehabilitation programs improved significantly compared with those who received no intervention.
Healthier choices are challenging to sustain long enough to make them a habit, but if you set goals, and keep working toward them, you can live a healthier and more comfortable life with COPD.
