Webb22 dec. 2024 · Obstructive lung disease is a condition where the airflow into and out of the lungs is impeded.1 This occurs when inflammation causes the airways to swell, making them narrower. Because of that, breathing well becomes harder and air often gets trapped in the lungs. This results in something known as hyperinflation of the lungs.
