What is the primary problem in obstructive lung disease?

Question

Quizplus · Accepted Answer

The primary problem in obstructive lung disease is increased airway resistance, which can be caused by inflammation, bronchospasm, and/or narrowing of the airways. This leads to difficulty exhaling and trapping of air in the lungs, resulting in symptoms such as shortness of breath, wheezing, and coughing. Low lung volumes (B) may be a secondary consequence of increased airway resistance, but it is not the primary problem. Increased pulmonary capillary pressure (C) is a characteristic of pulmonary hypertension, which is not necessarily associated with obstructive lung disease. Reduced lung diffusion (D) is a consequence of damage to the alveoli, but it is not specific to obstructive lung disease.
