Asthma is a respiratory disease characterized by the narrowing of lung airways due to triggers that cause swelling, inflammation, and excess mucus. It manifests when airways become obstructed, leading to symptoms such as coughing, wheezing, chest pain, excess phlegm, and shortness of breath. The causes of asthma are multifaceted, with exposure to airborne irritants, genetic predispositions, infections, and obesity playing significant roles. Managing asthma involves a comprehensive approach, including environmental interventions and consulting with healthcare providers.
