What condition does bronchiectasis describe?

Bronchiectasis is characterized by the abnormal dilation of the bronchi, which are the large air passages that lead from the trachea (windpipe) to the lungs. This dilation occurs as a result of chronic inflammation or infection, leading to damage that affects the structural integrity of the bronchial walls. As a result, the airways lose their elasticity and become widened. This condition often results in a buildup of mucus, which can become a breeding ground for bacteria and lead to frequent respiratory infections.

Understanding the nature of bronchiectasis is important for recognizing its symptoms and underlying causes. Symptoms typically include chronic cough, production of large amounts of sputum, and recurrent respiratory infections. By identifying bronchiectasis as an abnormal dilation of the bronchi, it emphasizes the need for appropriate management and treatment to prevent complications and improve lung function.
