I still feel lousy and hypo. I’ve been on 87.5 mcg Levo since December 2022. I weigh 9 stone (57 kg), usually cold - basal temperature 36.2, or sweating, basically poor temperature control, fatigue, digestive problems, constipation, exercise intolerance. My LDL cholesterol is high at 3.4 nmol/L (1.0-3.0). Having said that, I have more energy and sleep is better than on my previous dose of 75 mcg. I’m on Levo monotherapy and a steroid, Fludrocortisone, for low BP. Am post-menopausal.
I have an annual appointment with an NHS endo, and I asked him for a trial of T3, which I know in theory I am entitled to ask for if I’m not well on just Levothyroxine. The blood tests he did (9am fasting before meds) were as follows:
TSH: 0.07 mU/L L (0.35-5.00)
FT4: 15.5 pmol/L (9.0-22.0) ( 50% through ref range)
FT3: 3.4 pmol/L (2.4-6.0) (27% through ref range)
25 OH vitamin D: 101 nmol/L (50-200)
Vitamin B12: 554 ng/L (200-910)
No folate or ferritin tests, but folate usually high in range and ferritin usually too high.
My test results when on 75 mcg Levo December 2022 (Medichecks) were:
TSH: 1.69 mU/L (0.27-4.2)
FT4: 15.4 pmol/L (12-22) (32% through range)
FT3: 4.29 pmol/L (3.1-6.8) (34% through range)
So it looks to me like on the higher dose of Levo my FT4 has gone up but my FT3 has gone down and is too low for me to feel well, and conversion has got worse, and TSH is suppressed, to my mind a good case for a trial of T3, but the endo ‘s letter states:
“The FT4 was 15.5 ie well within our normal range. The FT3 was 3.4 which is nicely in range (2.4-6.0). The TSH was suppressed at 0.07. These results do not indicate thyroid hormone under-replacement, if anything they suggest that there is somewhat over replacement. Given that FT3 is in range, there is no suggestion of poor T4 to T3 conversion issues. There is no indication therefore to change to a T4/T3 combination.”
All I can say is that I’m not functioning well on this “nicely in range” FT3.
I’d be extremely grateful for any advice or comments before I write a reply to him.
