Chronic Obstructive Pulmonary Disorder can affect non-smokers too; smaller airways may be to blame, finds study
FirstpostA group of scientists concluded that smaller airways relative to lung size is a strong risk factor for COPD as these people would already have low lung function from the beginning. COPD, a deadly lung disease Chronic Obstructive Pulmonary Disorder, commonly called COPD, is a lung disease which worsens the condition of the lungs progressively, making it difficult for one to breathe. The comparison showed that people who never smoked but had COPD had smaller airways relative to lung size, whereas the heavy smokers who did not have COPD had larger than normal airways.
