What is the medical term meaning dilation of a bronchiole?

The correct medical term for the dilation of a bronchiole is bronchiectasis. This condition is characterized by the widening and deformation of the bronchioles, which are the small airways that branch off from the bronchi in the lungs. Bronchiectasis can cause a variety of respiratory symptoms, including chronic cough, shortness of breath, wheezing, and recurrent chest infections. In severe cases, bronchiectasis can lead to lung damage and respiratory failure.
