Is bronchiectasis like copd?

A little different: COPD is due either to obstruction and excessive secretions from the smaller bronchioles. Whereas bronchiectasis is due to weakness of terminal bronchioles causing secretions to stagnate and get infected. It produces copious amounts of purulent secretions. Treatment may be similar in both conditions.

Different cause: Some symptoms like shortness of breath and sputum production are the same, but the disease is different. A history of pertussis or other serious deep lung infection is frequently the cause of bronchiectasis where the bronchial tubes are chronically infected and inflamed with breakdown of the wall of the bronchial tube. The diameter of the bronchi is enlarged and abnormal.
