Original Question

Overview of Asthma Diagnosis Asthma is a chronic inflammatory disorder of the airways characterized by variable and reversible airflow obstruction. It is a prevalent condition, particularly among adolescents, and can be triggered by various environmental and genetic factors. Risk factors for asthma include a family history of asthma or allergies, exposure to tobacco smoke both prenatal and postnatal, respiratory infections during early childhood, and exposure to allergens such as pollen, dust mites, and pet dander. These factors contribute to the pathogenesis of asthma by promoting airway hyperreactivity and inflammation, leading to the typical symptoms of wheezing, coughing, and shortness of breath. Pathophysiology of Asthma The pathophysiology of asthma involves a complex interplay of genetic predisposition and environmental triggers. Over time, repeated exposure to these triggers leads to persistent airway inflammation, characterized by the infiltration of inflammatory cells such as eosinophils, mast cells, and T-lymphocytes (Wenzel, 2017). This inflammation causes structural changes in the airways, often referred to as airway remodeling, which includes thickening of the airway wall, increased mucus production, and hyperplasia of smooth muscle cells. Clinical signs and symptoms of asthma include: Wheezing: A high-pitched whistling sound during expiration due to narrowed airways. Coughing: Often worse at night or early in the morning.
