Does anyone have any thoughts on why my FT4 is so low?
I take 50mg levothyroxine and 20mg liothyronine.
Recent blood test:
FT4 - 8 (12-22)
FT3 - 4.4 (3.1-6.8)
TSH - 0.7 (0.27-4.2)
I believe that when taking liothyronine FT4 can be low however I have had symptoms creep up on me again - feeling tired and cramping/aching legs.
GP says he is concerned that my FT4 is so low and has told me to see Endo again - I have an appointment on Monday and would appreciate any thoughts on the above recent results.
Prior to starting liothyronine I was on 100mg levothyroxine (TSH 0.173, FT4 19.69, FT3 4.6) however still had really bad cramping/aching legs.
Vitamin D levels are kept topped up with 4000 IU a day after finding I was significantly deficient in Jan.
Thank you in advance for your thoughts
