Cycling and warfarin?

[OakLeaf]

I would be more concerned that your DH has been cleared to resume endurance activities, or at least building up to his former level.

I would second that. I think it's much more a concern with running than cycling, but there's plenty of evidence that a lot of capillaries get broken during the repetitive micro-trauma of endurance sports, and that would worry me if I were on a blood thinner.

All I really know about warfarin comes from experience with sedentary people - but I do know that it's extremely important to keep one's diet very consistent. Doctors will tell you to do that by eliminating most green vegetables. That at least rules out the possibility that you might accidentally eat more vitamin K rich foods one day and less the next, if you never eat any at all. But I think it's possible to count vitamin K in the same way that diabetics count carbohydrates. That might be more work than either of you has time for though. It's also super important to keep up with the blood testing, twice a week or whatever the doctor recommends.
