DescriptionAn abnormal condition of the lungs in which there is over inflation of the air sacs of the lungs, leading to a breakdown of their wall, a decrease in respiratory function, and, in severe cases, increasing breathlessness. It appears to be associated with chronic bronchitis, smoking and advancing age; one form that occurs early in life is related to a hereditary lack of an enzyme.
