Overview

Natural History

Depending on the severity of airflow obstruction which could be measured by FEV1, FVC and FEV1/FVC and at the time of diagnosis the prognosis may vary. It has a very wide range of severity from well controlled chronic bronchitis to severe obstructed airways with multiple exacerbations that needs hospitalization and even may develop to lung cancer[1].COPD usually gradually gets worse over time and can lead to death if left untreated.

Complications

Common complications of chronic bronchitis include:

  • Recurrent pneumonia: Chronic inflammation and airways damage predispose chronic bronchitis patients to recurrent pneumonia either viral or bacterial infections. Additionally, chronic use of inhaled corticosteroids may cause recurrent infections[2].
  • Depression: If it happens needs psychiatry consultation[3].
  • Cor pulmonale:chronic hypoxia and subsequent vasoconstriction in pulmonary vasculature results in pulmonary hypertension and right sided heart failure which is named as cor pulmonale[4].
