Gastrectomy, on coumadin, very high INR levels what correlation, if any, is there between gastrectomy history, some dumping syndrome...on Coumadin for Afib and inexplicable INR of 4.7 from 2.6 the day before and 1 or 2mg coumadin administration the day before? I ended up giving 5 mg vit K oral, it brought it down ot 1.8 next day.
I know that gastrectomy will have impaired fat-soluble vitamin metabolism, so is that what I am looking at?
thanks
