Bronchiectasis is a chronic lung condition characterized by the abnormal widening and damage of the airways, known as bronchi. This damage often results from repeated infections or inflammation, leading to the accumulation of mucus. The trapped mucus can create an environment for bacteria to thrive, increasing the risk of respiratory infections. Symptoms of bronchiectasis may include a persistent cough, production of large amounts of mucus, shortness of breath, and frequent lung infections. Diagnosis typically involves imaging tests like a CT scan and may require lung function tests to assess the severity of the condition. Treatment focuses on managing symptoms and preventing infections.
