I'm hoping someone can shed light on whether my NDT is working as my GP is concerned about my low TSH and has referred my to an endo with a view to taking Levothyroxine.
Results 6 months ago (pre -NDT):-
Serum free T3 4.4pmol/L (3.5-6.5)----normal
Serum free T4 10pmol/L (9-23)-----normal
Serum TSH level 4.8 mu/L (0.55-4.8)--normal
Results on 4th November after getting my NDT intake up to 4 grains per day (from mid-October, up from 2 grains):-
Serum free T3 6.4 pmol/L (3.5-6.5)----normal
Serum free T4 10 pmol/L (9-23)-----normal (although verbally GP says she's seen recent result of 8 pmol/L)
Serum TSH level 0.04 mu/L (0.55-4.8)--abnormal
Folate - >24
Vit D - 106
Ferritin - 13 (I'm aware this is low and am taking Spatone now)
Vit B12 - 616
Calcium - 2.28
Adj calcium conc - 2.29
Serum albumin - 41
From what I've read on this site my low TSH shouldn't be a concern but am I right in thinking I need to get my T4 up? If so should I increase my NDT dose?
I've been told I have Hashimoto's. I also have Rheumatoid arthritis and have been taking Methotrexate for the last 10 weeks and I'm not sure whether this will affect my thyroid condition.
Although my GP seems concerned about my results I actually have more energy than I've had in a long while. My main symptom is a 'stuffy' head and a blocked ear but I think this is my recurring otitis externa (although I did note on a recent post that one symptom of a dysfunctional thyroid is blocked ears!).
Any help would be appreciated.
