👉 Bronchiectasis, also known as bronchial asthma or asthmatic bronchiolitis, is a chronic obstructive pulmonary disease (COPD) that typically affects the airways of the lungs. It is characterized by persistent coughing, wheezing, and difficulty breathing in response to small irritants such as dust, smoke, or pollen. The term "bronchiectatic" refers to the presence of tiny airway tubes called bronchioles (tiny air passages)
