Bronchiectasis is a chronic lung disease marked by permanent airway dilation, mucus accumulation, recurrent infections, and persistent inflammation. Affecting approximately 1 million individuals worldwide, the disease is associated with COPD, cystic fibrosis, severe respiratory infections, or congenital disorders. Patients experience chronic cough, sputum production, fatigue, and progressive lung function decline, impacting overall quality of life. Rising awareness and improved diagnostics have increased the demand for targeted therapies in bronchiectasis management.
