Does bronchiectasis significantly cut a persons life span? secondly can it be cause of chronic fatigue? thanks

It depends: on the severity. It can range from being so minimal and localized that it is not clinically significant, to being so severe that lung transplant might be indicated. It can be idiopathic(no discernible cause) or acquired secondary to a number of causes(e.g. pneumonia, TB, cystic fibrosis). It is a form of COPD, and if severe enough can impact morbidity/mortality, and cause chronic fatigue.
