Chronic Bronchitis is a common type of COPD, or Chronic Obstructive Pulmonary Disease. In the lungs of a patient with chronic bronchitis, airflow may be limited by narrowed airways that get tight, swollen, and filled with mucus. These changes limit airflow into and out of the lungs. The most common cause is cigarette smoking.
United States – Approximately 16.4 million people suffer from this disease. According to the American Lung Association, approximately 14 million people suffer from chronic bronchitis, the seventh leading chronic condition in the United States.
