Bronchiectasis is an irreversible widening of the bronchi, the air-carrying tubes in the lungs, resulting from damage to the muscle and elastic tissues in their walls, typically due to infection or inflammation. While most commonly seen in the left lower lobe, it is also prevalent in the lingula and right lower lobe. This condition leads to a permanent enlargement and thickening of the bronchi, causing significant mucus accumulation and difficulty in clearing mucus. This cycle predisposes to recurrent lung infections. Typical symptoms of the disease include persistent cough, shortness of breath, copious sputum production, fever, and occasional bloody sputum (hemoptysis). Although there is no definitive cure for bronchiectasis, symptoms can be managed with medications such as antibiotics and bronchodilators.
