Increased Hemoglobin Level. Going For Knee Replacement Surgery. On Warfrin. Should I Be Concerned?

Are patients on blood thinners more susceptible to low or drops in hemoglobin levels? What causes that drop? My Dad is currently going through a blood transfusion, in another country, where I can't just call the doctor and ask what is going on. I'm trying to research answers to keep my brain busy. He went in for knee replacement surgery. He has a metal heart valve, so is on Warfarin, and has been stable on that for years. But apparently his hemoglobin dropped to 77 (from 150, three days ago pre-knee surgery). I'm trying to understand a little more so I know what risks for him might be.

HI
Thank for asking to HCM
No blood thinner can not drop the level of hemoglobin, certain pathological conditions and loss of blood is responsible for this, if your father has history of valvular heart disease then great care has to be taken while going for or thinking for major surgery, in old age knee pain is so common but it does not need a surgery in all such cases, please take care your father, good day.
