I was diagnosed with an underactive thyorid in 2008. After being on levothyroxine for years, I paid to see a private endocrinologist and switched to Erfa (NDT) in Feb 2016. Had last load of blood tests in May and was feeling pretty good, taking 120 mg of Erfa a day. Now am due for a six-month check-up and starting to feel rubbish again (tired, cold, achey, really noticed it over last two months). See results below:
TSH: 0.8 (0.27-4.20)
Free Thyroxine: 8.94* (12-22)
Total Thyroxine: 49* (59-154)
Free T3: 5.11 (3.1-6.8)
Thyroid Antibodies: 188* (0-115)
B12 - 212* (25-165)
Folate: 7.44 (2.91-50)
Vit D: 54 (50 - 200)
Ferritin: 50 (13-150)
These were my results in May 2017 (when I was feeling pretty fabulous)
TSH - 0.189 (0.27 - 4.20)
Free Thyroxine: 11.1 (12.00 - 22)
Total Thyroxine (T4): 61.5 (59-154)
Free T3: 4.55 (3.10 - 6.80)
Thyorid Antibodies: 196 (0-115)
Vit B12 - 1083 (140-724)
Folate: 16.53
Vit D: 84.63 (50-200)
Ferritin: 208 (13-150)
After the May results, I stopped taking the ferrous sulphate supplements (because I'd been on them for 18 months) and my ferritin levels seem to have now plummeted (from 23 in August 15 to 42 in Feb 2016, 57 in Oct 2016, 112 in April 17 and then 208 (i'd doubled dose!) and now 50. Main reason for going down endo route was thinning hair and it had definitely got thicker. Now worried it's going to start shedding again. I do take Vit D and b12 (a bit sporadically); had figured that I was out in sunshine a lot over the summer. My diet is good and I'm very active (three small children and a job), but at the moment at the end of the day, as soon as I sit down, it literally feels like I've been drugged/am almost slurring with tiredness. Please help! I really want to go armed with a plan on Thursday.
Really, if it isn't the erfa that makes the difference should I switch back to the Levothyroxine - it's free and easily available. Is it that my body is just rubbish at absorbing vits and minerals? I've got a full house at Christmas and a busy time ahead and the thought of doing it all while feeling like I'm knee-deep in custard is really stressful.
Do let me know if you need to know anything else.
