Sorry Daffodil, but your consultant is talking rubbish! Bronchiectasis, cannot "disappear", because it causes irreparable damage to the lungs. I can only imagine that if you had this at all, it was so minor that it has not made that much difference to your daily functions. However, unless you have that small part of the infected lung removed, it will always be there - but manageable. It can get worse and infect larger areas of your lungs if you abuse it e.g. smoking etc. When I was a child I had pneumonia several times and this is what caused the damage initially, and consequently, bronchiectasis to my right lung. As a teenager not wanting to be the odd one out, I smoked. The impact of my actions did not show for many years - apart from the "smoker's cough" But believe me, the disease was always there and without my knowledge continued to spread to a larger area of my lung - and later still, both lungs. I stopped smoking many years ago, but the damage was already done and starting to show results. You cannot replace damaged lung area - it's not like the liver which can regenerate itself to a degree. If you've been diagnosed with COPD (chronic obstructive pulmonary disease) this includes bronchiectasis not "plus" it. I can only think that your consultant saw something else as well- maybe mild emphysema or asthma? Get a second opinion if you're concerned. We have the benefit in this country of free treatment and you are entitled to it. Don't know if this helps, but "trust me, I'm a Doctor!"
