Asthma

Asthma is a chronic inflammatory disorder of the airways characterized by recurrent episodes of wheezing, coughing, chest tightness, and shortness of breath, caused by bronchial hyperresponsiveness and variable airflow obstruction. It commonly affects children and young adults, with over 25 million cases in the United States, and results from complex interactions between genetic predisposition and environmental triggers such as allergens and pollutants. Symptoms are often reversible with treatment, and effective management involves identifying warning signs, avoiding triggers, and adhering to medical recommendations.
