I have had an under active thyroid for 23 years (it was over active for a few weeks at first before it went low). It has been fairly stable on 100mcg Levothyroxine and I have managed quite well (apart from early nights and the need for 9 hours sleep). Results from my GP from July 2017 were as follows:
TSH 0.38 (0.3 - 5)
Free T4 13.4 (7.9 - 16)
Recently I felt very anxious and started to lose weight (although this has stopped) so I asked Blue Horizon to test my thyroid.
Results are surprising: 24.3.18
Total T4 118 (59 - 154 nmol/L)
TSH 0.22 (0.27 - 4.2 m/u/L)
Free thyroxine 22.8 (12 - 22pmol/L)
Free T3 4.3 (3.1 - 6.8 pool/L)
Thyroglobulin antibody 18.3 (0 - 115)
Thyroid peroxidase antibodies 93 (0 - 34iu/ml)
I have injections for B12 deficiency and am no longer symptomatic.
I take the required vitamins and eat a healthy diet for thyroid and b12 def.
Grey Goose has suggested that I might not be converting T4 to T3 and may benefit from trying some.
Could anyone tell me where to get it and how much to take please as currently I'm so tired I'm not able to do much at the moment at all?
