Hi I read the replies to 'Anybody at their best Ft4 16-17?' yesterday and am now confused about my own results which is a problem as I have GP appt tomorrow.
Clutter was the only person to reply when I put these results on my last post 'Exercise and TSH - new blood results !' and we seemed to agree that though my T4 is high and TSH low, as long as my FT3 was in range and no hyper symptoms then fighting to stay on 125mcg was reasonable.
I feel 'normal' the best I have since diagnosis, bar some tiredness which I think is explained by my vitamin results, definately NO hyper symptoms. My dry patches/splits are finally healing and I appear to be producing oil in my scalp and skin again which bodes well for my hair loss issues. My brain fog is greatly improved and again probably vitamins
I felt awful on 100mcg and really do not want to mess things up when I feel so well, but then I read replies on the mentioned post like - TSH stimulating conversion - stimulting deiodinase activity - keeping TSHhungry........ and my brain hurt.
Research found this paper which suggests my TSH is low but not quite suppressed so no identified risk of heart/bone issues
I was beginning to suspect a conversion issue as both my TSH and FT4 were rising together, albeit T4 slowly (see bio) and symptoms not improving - no FT3 done by lab of course. Now Ive had this huge jump on a little increase. I am assuming no issues with pituitary itself??
So...... in light of below results I would appreciate advice. Please dumb down anything too technical, Ive been on nights !!!!!!
NHS ranges - TSH -0.3-4.2. FT4 -12-22 noFT3
23/01/17 - 5.1 - 16.7 - raised to 125mcg from 100mcg
22/03/17 - 0.05 - 23.3
MEDICHECKS ranges - TSH -0.3-4.2 FT4 -12-22 FT3-3.10 - 6.8
22/03/17 - 0.051 - 21.81 - 4.78
B12 164 pmol (140-724) -sub optimal
folate 6.54 ug (3.89-26.80) - sub optimal
25 OH D 15.24 nmol (50-200) - dire
ferritin 141.2 ug (13-150) - slightly above optimal?
(No exercise for 2 days due to heavy cold)
(fasting early morning tests before levo)
Should I ask to keep 125mcg until we sort out vitamins, which may be interfering with conversion of T4 hence the need for so much of it to get decent T3 level where I feel normal?.
