After posting on here that I had been told to stop warfarin five days before a colonoscopy, and getting lots of helpful advice, I rang the hospital department where I was due to have the procedure and said I didn't want to stop warfarin without bridging. The specialist nurse from an associated hospital rang me the day before I was due to stop warfarin and said the doctor said I am low risk - to just start taking warfarin again after the procedure. I told the nurse I was extremely unhappy with that decision having recently come out of a 70-hour AF episode. He spoke to the doctor, called me back and I had to go and pick up a supply of Fragmin with full instructions on bridging. No bleeding problems during the colonoscopy after two polyp biopsies.
Thank you all!
