Does anyone have any knowledge of this? Secondary most likely.
My question is, if patient was a smoker and then stopped, and assuming smoking was the likely cause of the secondary polycythemia, how quickly would you expect to see if difference in the haemoglobin concentration?
I have another millionth blood test scheduled for next Thursday. I stopped all smoking this Monday evening. So will be 9 days ...
Too soon?
I don't want to get too hopeful as if it doesn't at least start to return to normal levels then I'll be convinced I have something more sinister causing it 
Also, I've quit the fags
we all know it's bloody bad for your health but I REALLY need to see the results and therefore will never smoke again!
On a positive note, I definitely feel so much better today (and rather suddenly) than I have in months and some of my more persistent symptoms have subsided. Hopefully not just a random one off.
