Asthma is a chronic respiratory condition characterized by airway inflammation, increased airway responsiveness, and reversible airflow obstruction. Affecting millions worldwide, asthma can significantly impact daily life, resulting in reduced quality of life and increased healthcare costs. This article aims to provide a comprehensive overview of asthma, including its pathophysiology, clinical manifestations, triggers, diagnosis, and management strategies. The airways in asthma patients exhibit chronic inflammation due to various immune responses, leading to the infiltration of eosinophils, mast cells, and T lymphocytes. This inflammation results in the release of inflammatory mediators such as histamines, leukotrienes, and cytokines, contributing to airway hyperresponsiveness. Asthmatic individuals have an exaggerated bronchoconstrictive response to a variety of stimuli, including allergens, cold air, exercise, and irritants. This hyperresponsiveness leads to increased smooth muscle contraction around the airways, resulting in wheezing and breathlessness. In asthma, airflow obstruction can be due to a combination of bronchoconstriction, mucus hypersecretion, and airway remodeling. The remodeling process involves structural changes in the airway wall, including smooth muscle hypertrophy, subepithelial fibrosis, and glandular hyperplasia, contributing to persistent airflow limitation. Asthma symptoms can vary in severity and frequency among individuals. Asthma symptoms can be categorized as intermittent or persistent based on their frequency and severity. Intermittent asthma is characterized by symptoms occurring less than twice a week, while persistent asthma requires daily management and often has more frequent and severe symptoms. Asthma triggers can be categorized into 2 main types: Allergic and non-allergic. Pollen, dust mites, mold spores, pet dander, and cockroach droppings can provoke allergic responses, leading to asthma exacerbations. Tobacco smoke, air pollution, strong odors, chemical fumes, and cold air can irritate the airways and exacerbate symptoms. Viral infections, such as the common cold or influenza, are common triggers for asthma exacerbations, especially in children. Physical activity, particularly in cold, dry air, can induce bronchoconstriction, leading to exercise-induced asthma. Stress and strong emotions can exacerbate asthma symptoms through physiological pathways that increase airway reactivity. Understanding individual triggers is crucial for effective asthma management, as it allows for the development of personalized avoidance strategies. Diagnosing asthma involves a combination of patient history, physical examination, and lung function tests. A thorough assessment of the patient’s symptoms, family history of asthma or allergies, and potential environmental exposures is essential. Observing for signs of respiratory distress, wheezing, and use of accessory muscles during breathing can provide valuable insights. This lung function test measures the volume and speed of air that can be forcibly exhaled after taking a deep breath. A reduced forced expiratory volume in one second and an improvement in FEV1 after bronchodilator administration indicate reversible airway obstruction, consistent with asthma. Patients may be advised to use a peak flow meter at home to track their lung function regularly. This can help identify worsening symptoms or an impending asthma attack. Skin or blood tests can identify specific allergens that may trigger asthma symptoms, allowing for targeted management strategies. Managing asthma effectively involves a comprehensive approach that includes pharmacological interventions, non-pharmacological strategies, and regular monitoring. Pharmacological treatment for asthma can be categorized into 2 main classes: controllers and relievers.
