How is asthma characterized?

• A. Chronic respiratory infection
• B. Chronic inflammatory disorder of the airways
• C. Acute bronchospasm
• D. Common cold symptoms

Answer: (B)

Asthma is characterized primarily as a chronic inflammatory disorder of the airways. This means that the airways within the lungs are persistently inflamed, which leads to various respiratory symptoms. In asthma, this inflammation results in heightened sensitivity to various triggers, including allergens, smoke, exercise, and respiratory infections. The inflammation causes the airways to narrow and become obstructed, leading to symptoms such as wheezing, shortness of breath, chest tightness, and coughing.

This chronic condition is distinct from an acute bronchospasm, which refers to a sudden constriction of the airway muscles that can occur in the context of asthma but does not encompass the ongoing nature of the disease itself. Additionally, while asthma may follow after a respiratory infection, it is not characterized as a chronic respiratory infection like chronic bronchitis, nor does it present typical symptoms of the common cold, such as sneezing or a runny nose without underlying airway inflammation. Understanding asthma as a chronic inflammatory disorder is key to recognizing its long-term management and treatment strategies.
