It does make me wonder if the clotting complications develop as a consequence of oxygen shortage -- i.e., the body cranks up its own production of EPO, and that in turn causes clotting? (This is merely speculative on my part.)

It might suggest suppressing natural over-expression of EPO could help prevent some of these complications.
Good point about clotting. But, there may be target ranges of HCT that would improve oxygenation at minimal risk.

I had an acquaintance a few years ago with the polycythemia. he had regular blood-letting. But, he also chain smoked, and perhaps it was in part related to carbon monoxide.
