The chronic obstructive pulmonary disease is a progressive lung disease where a person typically suffers from emphysema and chronic bronchitis.
Emphysema is a lung condition where the alveoli, which are the tiny sacs in the lungs that allow the passage of oxygen between the lungs and the bloodstream are destroyed. Chronic bronchitis is a lung condition in which the lining of the bronchial tubes start narrowing and suffer from inflammation.
The symptoms of COPD start on a mild side and if left untreated they become severe with the passage of time.
