Bronchiectasis is a condition in which the airways of the lungs become abnormally wide, leading to excess mucus buildup and possibly making the lungs more susceptible to infection. Treatment for bronchiectasis is mainly supportive, decongestant, and anti-infective.

Bronchiectasis is a condition of irreversible dilation of part of the bronchial tree, making it difficult to move phlegm and mucus from the lower respiratory tract to the upper respiratory tract and creating conditions for the growth of bacteria causing inflammation. The diagnosis of bronchiectasis depends largely on diagnostic imaging methods, especially chest CT scans, which help to show the area and severity of bronchiectasis as well as clues about the cause of the disease.
