The matter of whether or not to treatis actually a two part question.
Having Bronchiectasis means most people need airway clearance to keep mucus from building up and allowing infections like MAC to take hold. This can be as simple as a vibratory device like Aerobika followed by huff coughing to bring it up, to nebbing saline alone or in combination with other drugs, to use of a percussion vest.
If infection takes hold – often indicated by fatigue, fever, weight loss and chronic cough – more drastic action may be required. First it is very important to have a sputum sample tested, using a culture that takes up to 6 or 7 weeks, to identify the specific bacteria and what drug(s) it responds to.
These are the things your pulmonologist will discuss with you. CT scan results need knowledgeable interpretation and explanation. The raw reports still scare the heck out of me.
Good luck and let us know what you learn at your appointment.
