Chronic bronchitis is one of the main types of chronic obstructive pulmonary disease (COPD), an umbrella term to describe a group of long-term lung diseases that block airflow and make breathing difficult. Your doctor may refer to your disease as either chronic bronchitis or COPD.

What Is Chronic Bronchitis?
Bronchitis is an inflammation of the lining of the bronchi, the large tubes that carry air from your windpipe to your lungs.
Bronchitis can be either acute or chronic.
Patients with chronic bronchitis can have “exacerbations,” often caused by viral acute bronchitis, on top of their chronic condition.
