While I was trying to find some information about rhinitis and hypothyroisim (having suffered lot myself ever since my TT) I came across this extract from a Turkish study:
The following conclusion was drawn:
Besides other examinations, thyroid functions should also be assessed in patients presenting with rhinitis symptoms.
I was struggling to find anything specific on TUK . There is information on 'Breathing problems' in general, primarily decreased Lung Function, but not about the constant nasal obstruction of Perennial Rhinitis.
I have suffered from this for years, so I found this very interesting. I have had to have two operations to remove polyps from my nose, which the surgeon assured me were the result of the constant nasal obstruction.
