Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs are damaged. Over time, the inner walls of the air sacs weaken and rupture creating larger air spaces instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches the bloodstream.
Upon exhaling, the damaged alveoli don’t work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter.
The main cause of emphysema is long-term exposure to airborne irritants, including:
Rarely, emphysema is caused by an inherited deficiency of a protein that protects the elastic structures in the lungs. It’s called alpha-1-antitrypsin deficiency emphysema.
Most people with emphysema also have chronic bronchitis. Emphysema and chronic bronchitis are two conditions that make up chronic obstructive pulmonary disease (COPD).
The main symptom of emphysema is shortness of breath, which usually begins gradually and advances until it occurs even at rest.
Patients with unexplained shortness of breath for several months should see a doctor, especially if it’s getting worse or it’s interfering with daily activities.
A Deborah physician will take a full medical history and do a physical exam. Additional tests may be ordered.
By participating in this quiz, or screening or health assessment, I recognize and accept all risks associated with it. I understand that the program will only screen for certain risk factors and does not constitute a complete physical exam. For the diagnosis of a medical problem, I must see a physician for a complete medical exam. I release Deborah Heart and Lung Center and any other organization(s) involved in this screening, and their employees and agents, from all liabilities, medical claims or expenses which may arise from my participation. Thank you for investing in your health by participating today.
