People with severe COPD see their doctor monthly or every two weeks. Those with less severe symptoms may see their doctor every few months.
Also known as chronic obstructive pulmonary disease; chronic bronchitis; or emphysema. COPD, or chronic obstructive pulmonary disease, is a progressive disease that makes it hard to breathe.
Progressive means the disease gets worse over time.
Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. However, up to 25 percent of people with COPD never smoked.
Long-term exposure to other lung irritants—such as air pollution, chemical fumes, or dusts—also may contribute to COPD.
A rare genetic condition called alpha-1 antitrypsin AAT deficiency can also cause the disease. Within the lungs, your bronchial tubes branch many times into thousands of smaller, thinner tubes called bronchioles. These tubes end in bunches of tiny round air sacs called alveoli. Small blood vessels called capillaries run along the walls of the air sacs.
When air reaches the air sacs, oxygen passes through the air sac walls into the blood in the capillaries. At the same time, a waste product, called carbon dioxide CO2 gas, moves from the capillaries into the air sacs.
This process, called gas exchange, brings in oxygen for the body to use for vital functions and removes the CO2. The airways and air sacs are elastic or stretchy. When you breathe in, each air sac fills up with air, like a small balloon.
When you breathe out, the air sacs deflate and the air goes out. In COPD, less air flows in and out of the airways because of one or more of the following: The airways and air sacs lose their elastic quality.
The walls between many of the air sacs are destroyed. The walls of the airways become thick and inflamed. The airways make more mucus than usual and can become clogged. The inset image shows a detailed cross-section of the bronchioles and alveoli.
The inset image shows a detailed cross-section of the damaged bronchioles and alveolar walls. In emphysema, the walls between many of the air sacs are damaged. As a result, the air sacs lose their shape and become floppy.
This damage also can destroy the walls of the air sacs, leading to fewer and larger air sacs instead of many tiny ones. If this happens, the amount of gas exchange in the lungs is reduced.
In chronic bronchitis, the lining of the airways stays constantly irritated and inflamed, and this causes the lining to swell.
Lots of thick mucus forms in the airways, making it hard to breathe. Most people who have COPD have both emphysema and chronic bronchitis, but the severity of each condition varies from person to person.
Thus, the general term COPD is more accurate. Currently, 16 million people are diagnosed with COPD. Many more people may have the disease and not even know it.
Symptoms often worsen over time and can limit your ability to do routine activities. Severe COPD may prevent you from doing even basic activities like walking, cooking, or taking care of yourself. Most of the time, COPD is diagnosed in middle-aged or older adults. The disease is not contagious, meaning it cannot be passed from person to person.
COPD has no cure yet, and doctors do not know how to reverse the damage to the lungs.Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a long-term lung disease that makes it hard to breathe.
