I Have Been Told That My Liver Is Not Function

I have been told that my liver is not function properly? Also that I have anaemia and my iron is low.
I am on Thyroxine because I had a Total thyroid removal, Amiarodorone and Aldactone for AF, Nexium for Reflux, Frusimide for Fluid retention, Xarelto for blood thinning. I also take Lyrica because I have Peripheral Neuropathy. I am about to have another TKR this time on my right knee so have been having blood tests. I do also take Panadol Osteo for pain. Bio Magnesium and Ostelin I take every day but assume they are okay. I guess I am concerned with all these tablets. My name is anne and the email is YYYY@YYYY
