What causes COPD ?
COPD is a disease that slowly worsens over time, especially if you continue to smoke. If you have COPD, you are more likely to have lung infections, which can be fatal. If the lungs are severely damaged, the heart may be affected. A person with COPD dies when the lungs and heart are unable to function and get oxygen to the body's organs and tissues, or when a complication, such as a severe infection, occurs. Treatment for COPD may help prevent complications, prolong life, and improve a person's quality of life.
