CAUSES :-

The two most important key factor which causes chronic bronchitis are the cigarette smoking and atmospheric pollution. Other factors which causes chronic bronchitis are occupation, infection, familial and genetic factors.

A.] SMOKING : Heavy cigarette smokers have 4 to 10 times higher proneness to develop chronic bronchitis. Prolonged cigarette smoking appears to act on the lungs in a number of ways like – it impairs the ciliary movements, it inhibits the function of alveolar macrophages etc.

B.] ATMOSPHERIC POLLUTION : The risk of having chronic bronchitis is higher in the industrial urban areas where air is polluted. Some atmospheric pollutants like sulfur dioxide, nitrogen oxide, particulate dust and toxic fumes increases the rate of having chronic bronchitis.

C.] OCCUPATION : Workers working in cotton mills, plastic factories etc. have a greater risk of having chronic bronchitis.

D.] INFECTION : Cigarette smoke, however predisposes to infection responsible for acute exacerbation in chronic bronchitis.

E.] FAMILIAL AND GENETIC FACTOR : There appears to be a poorly defined familial tendency and genetic predisposition to develop disabling chronic bronchitis.
