Hi Sue
This is from AI
Yes, bronchiectasis can cause mucus plugs, as it is characterized by impaired mucus clearance and an accumulation of mucus. The chronic inflammation and structural changes in the airways of those with bronchiectasis lead to mucus that is thicker and more prone to forming plugs, particularly in the distal airways.

Also
This is from my bronchoscopy report:

Mucus, plugging the
airway, was found throughout the tracheobronchial
tree. The mucus was copious, white and thick. The
underlying mucosa is erythematous. Virtually all
segmental airways were plugged with long tenacious
plugs. The scope was removed x 4 with long plugs in
tow, that would not pass thru the scope with maximal
suction. The plugs were up to 15 cm in length forming

Shoot I wish I could cough out this stuff!

@sueinmn I've been busy going between Texas and Oklahoma seeing doctors, so sorry to just be answering your question to me about the mucus plugs. I am going to paste and copy what I said to scoop due to what has been said and not said by us or the pulmonologists.
Scoop - I had my visits with the two pulmonologists and showed them and told them what I was bringing up...the soft yellow/green tint pieces. Both said to me....yes they are mucus plugs.
Also....AI info said....for what it is worth: "Yes, mucus can change from soft and pliable to hardened and even solidify over time in the lungs. This hardening can occur due to a variety of factors that cause mucus to become thick, stagnant, and dehydrated, such as infections, certain medical conditions like cystic fibrosis, and dehydration. In severe cases, this can lead to the formation of hardened "casts" that block airways."
Sue my 'mucus plugs' are soft light yellow and sometimes the yellow with a light green tinge. They can be spec size, short elongated, small globs with or without edges to it, and never hard. They are soft and pliable. They are no larger than, and are smaller than, an eraser on the end of a pencil, basically tiny.
I bring the mucus plugs up most every day and with some days more than others. My mucus that is not in the form of a mucus plug is clear.
Hope this helps explain what it is for me and what the pulmonologist confirmed as mucus plugs. I clear all that I huff cough up into a clear solo cup and all that comes up shows clearly. I took pictures of the cups from different angles, etc. and showed the doctors.
