Hi all, had my liver function tests done a couple of weeks ago because of my very high ferritin level. Ferritin is 322.2mcg/L (20-150) done by BH and LFTs done by my own doctor are ALT 212 IU/L (0-60), ALP 143 IU/L (46-116), GGT 55 IU/L (0-40). 1 am taking 75mcg levothyroxine and 17.5mcg liothyronine each day. I have read that Levo taken alone can cause high serum liver test levels and that to reduce them you come off T4 for a month or so then start taking T3 only and the levels can stay down. Does this suggest that I should be on T3 only? I wondered if I just came off T4 and increased T3 to compensate then my serum liver enzyme levels might reduce. I would not want to stop taking hormone for any length of time. Anyone got any thoughts on this?
