Sorry to hear you have bronchiectasis hun but glad you have joined us here. diagnosed just 3 days you must be quite overwhelmed so I will try to keep to keep info short and sweet!
I have had non cf bronchiectasis for 65 years at the age of 5 months old folllowing double pneumonia and whooping cough, so I have always lived with it and didn't get that shock diagnosis you have just experienced.
Check out online at your local hospital or Dr. Foster your respiratory consultant has a special interest in cystic fibrosis/bronchiectasis - believe me it can make a difference.
Your consultant should refer you to a respiratory physiotherapist who should teach you lung clearance techniques and gadgets such as the acapella or the flutter (you can now get the flutter on prescription) until you find a method which works best for you. Mucus clearance is the most important thing we can do for ourselves.
You will get to know what is normal for you eg sputum colour, when to recognise you have an infection coming on. You will need to have a supply of antibiotics at home for when you become ill over the holiday and weekend.
It is quite useful to get sputum samples cultured. 1. If the bugs are not sensitive to the ab you are taking, as soon as your results come back they can give you the right one. 2. It gives your docs and you a pattern of bugs you tend to grow.
Stick to the reputable sites only, the new one mentioned above, BLF and Bronchiectasis R Us.
Enough to be going on with I think, except write down any questions in bullet form for your consultant as you don't get long and don't want to forget anything. If there is anything you don't understand ask them to explain.
Any specific questions you have please feel free to ask.
Good luck hun
