Which statement regarding asthma is true?

Asthma is indeed a chronic condition that primarily leads to airway obstruction due to inflammation and hyperresponsiveness of the airways. In individuals with asthma, various triggers—such as allergens, irritants, exercise, and infections—can lead to bronchoconstriction, which narrows the airways and makes it difficult to breathe. This obstruction can be partial or complete and results from both acute and chronic inflammatory processes in the bronchial tubes.

In addition to airway obstruction, asthma can also lead to symptoms such as wheezing, coughing, chest tightness, and shortness of breath, all of which can significantly impact a person's quality of life and require ongoing management. This understanding of asthma as a chronic respiratory condition that causes airway narrowing and obstruction is essential in recognizing the importance of effective long-term treatment strategies.
