Why is FEV1 low in asthmatics?
In asthmatics, the airways become narrowed due to inflammation and constriction of the smooth muscles around the airways. This leads to difficulty in exhaling air from the lungs, resulting in a lower FEV1 (forced expiratory volume in 1 second) value. Additionally, increased mucus production in the airways can further contribute to decreased airflow and lower FEV1 measurements in asthmatics.
