How does one get any kind of Vitamin K those days 3 days before the Colonoscopy?
the human body is based on an age old design where food wasn't always a conveyor belt on the hour. You'll be fine.
sadly we've probably all done it ...
The bigger issue is managing your INR down during the procedure, as bleeding risks are higher during a colonoscopy. Discuss with your provider, but mine was happy to have me down to INR=1.4
PS: I just read you don't have a home monitor, so that makes things less than ideal (like driving a car with no speedo). I would suggest that you consider what I did and you can probably assume it will follow a similar pattern (what is your daily dose?)
Eventually one finds that some sort of small surgery is needed, for those of us on warfarin (perhaps after a large surgery such as a heart v...

I would suggest that you make a few changes though:
- simply cease warfarin not "lead in" with a half dose that I did (I can offer no logical reason why I did that)
- you can see I went 4 days without warfarin and that it was slower to return after I essentially "ran out of it" in my body. So I would suggest that if you cease 2 or 3 days before that you'll be something like 1.5 at procedure
- I would resume your dose with at least 2 doses of 50% more than you normally take
- if you are concerned about your thrombosis risk then consider heparin 24 hours after your procedure. If you are otherwise healthy, under 60 and have as your only issue the mechanical aortic valve then your thrombosis risk is low
Run that plan past your medical professionals.
