Bronchiectasis

Bronchiectasis refers to the irreversible and abnormal dilation of the bronchi due to damage to the bronchial walls caused by various factors. This condition is common in individuals over 40 years old, patients with chronic obstructive pulmonary disease (COPD), those with recurrent lung infections during childhood, and individuals with genetic mutations. Key symptoms include chronic cough, production of large amounts of purulent sputum, and recurrent hemoptysis.
