Quizplus · Accepted Answer

Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) that is commonly caused by prolonged exposure to cigarette smoke. While chronic asthma can also cause bronchitis-like symptoms, it is less likely to be the cause in a 25-year-old male who is only experiencing symptoms for 5 months. Air pollution and recurrent pneumonias can also be risk factors for COPD, but they are less commonly associated with chronic bronchitis specifically compared to cigarette smoke.
