I was diagnosed with an underactive thyroid in 2008 and been on levothyroxine ever since (200mg x 2 days a week, 100 the rest). I had some thyroidy-symptoms (inc hair loss, aching joints and fatigue) so saw an endo privately who prescribed Ertha, which i started two days ago. In the meantime, before starting on new regime got bloods done with medichecks and they were:
THYROID STIMULATING HORMONE 0.576 mIU/L 0.27 - 4.20
FREE THYROXINE 18.58 pmol/L 12.00 - 22.00
TOTAL THYROXINE(T4) 90.9 nmol/L 59.00 - 154.00
FREE T3 4.02 pmol/L 3.10 - 6.80
THYROGLOBULIN ANTIBODY *216.400 IU/mL 0.00 - 115.00
THYROID PEROXIDASE ANTIBODIES 23.22 IU/mL 0.00 - 34.00
VITAMIN B12 385 pmol/L 140.00 - 724.00
FOLATE (SERUM) 14.92 ug/L 3.89 - 26.80
25 OH VITAMIN D *19.39 nmol/L 50.00 - 200.00
Inflammation marker: CRP high sensitivity, 0.9 mg/l (0.00-5.00)
ferritin - 190.1 ug/l (13-150)
I've been on ferrous sulphate for a year as my ferritin has been low - when last tested in Nov, was still only 57 and with thinning hair, told to keep on it. Should I stop now as seem to be over-medicated?
Also, am literally two days into stopping levothyroxine and starting Erfa - but if my T3 is okay on levothyroixine and its more mineral deficiencies to blame for symptoms, am I dabbling where I needn't? (and having to pay for private prescription). Any advice would be amazing - I'm trying to work through the process as read about on here, but impatient to be feeling better after years (in retrospect) of feeling mildly rubbish. I have a toddler about to turn 2 and it was after his birth, that things started to feel more awry (also have older two boys, originally diagnosed after birth of second).
Thank you so much for all your help to date!
