Re: Re:
.....to the bolded.....the point is what we are talking about is nothing close to normal....we are talking about someone who is claiming to be absolutely the greatest endurance athlete of all time....and he did this with only half the normal complement of kidneys....yeah that makes a lot of sense....
Cheers
djpbaltimore said:Deja vu all over again. The continued attempt to link Greg Lemond's anemia to chronic kidney failure/ disease is very poor science. A person can have a normal healthy lifestyle with just 1 kidney. If Lemond had CKD during his cycling career, he would have had a kidney transplant by now. For perspective on the numbers, people start dialysis when they hit 15% function.
From page 171 of this thread.

One thing that immediately stands out is the strong correlation between (chronic) kidney failure and anemia.
Bottom line: If you suffer from the former, the chances are high you will also suffer from the latter.
Now Lemond's official version is he had chronic kidney infections since the day he was born, and has been riding around with just one functional kidney ever since he was a kid.
So if you go from there... to give any sort of credibility to the story that in 1989, after at least two decades of being a kidney patient, Greg didn't know he had anemia and needed his soigneur to tell him... well, that's one way of completely discrediting all the doctors Greg has ever worked with since a child, including his parents for failing to inform him on some of the very basics of being a kidney patient.
It's ridiculous.
No offense, but I'm not sure your arguments about the biology of this add up. Having a single functional kidney does not equate to Chronic kidney disease. CKD as stated in the NIH website is 'the permanent, partial loss of kidney function'. In this case it would be below 20%. That figure alone suggests why it is doable to cycle professionally with only one kidney. Anemia is more associated with later stage kidney failure and I think we can safely rule that out. IMO, the anemia suffered by LeMond is likely to have another cause and is not some undiagnosed condition relating to his kidney issues as you seem to be alluding to. Of course, maybe he never had anemia. YMMV.
Part of the problem is gleaning medical information filtered through people like professional cyclists who probably only have a rudimentary understanding of it themselves. I would take that kind of information with a large grain of salt.
