Hi migizii, do you see a pulmonologist who is experienced in treating bronchiectasis? What is the colonizing bacteria, and what can you learn about it? If you are coughing up sputum after respiratory therapy, is it clear or yellow/green? Have you had a CT scan to show if there is evidence of infectious damage to your lungs? I would be hesitant to "wait and see" without complete testing and evaluation by a specialist. The waiting advised by my family practitioner left me very ill, weak and fatigued before treatment commenced. My pulmonologist explained that damage from bronchiectasis leaves one susceptible to infection by bugs that normal lungs would be able to overcome, thus he may treat me now, but would not do so for a patient with normal lungs/lung function.
