After my initial post in the thyroid forum I've been recommended to post here for some more advice. I have had RAI in 2012 after being diagnosed with Graves disease, and because I was beginning to feel rubbish again I had a private blood test in December 2016:
TSH = 0.711 (0.27-4.2)
Free thyroxine = 17.07 (12-22)
Total thyroxine T4 = 132 (59-154)
Free T3 = 4.13 (3.1-6.8)
Thyroglobulin antibody = 25.71 (0-115)
Thyroid peroxidase antibodies = 9.39 (0-34)
Vitamin B12 = 120 (191-663)
Serum folate = 1.54 (3.89-26.8)
Ferritin = 7.18 (13-150)
I was advised to consult my GP, who requested further blood tests in February 2017:
Serum B12 = 195 (150-99999)
Serum folate = 2.4 (4.2-19.8)
White blood count = 8 (4-13)
Haemoglobin concentration = 111 (115-165)
Haematocrit = 0.369 (0.35-0.47)
RBC count = 4.57 (3.9-5.6)
MCV = 80.7 (73-100)
Mean cell haemoglobin level = 24.3 (26-32)
Mean cell haemoglobin concentration = 301 (300-350)
RBC distribution width = 16.1 (11.8-14.8)
Serum ferritin = 6 (15-150)
Serum TSH = 2.11 (0.25-4)
Free T4 = 16 (12-22)
I am feeling awful. I am exhausted. My eyes are painfully dry and I've had a couple of episodes where there has been a small area of vision that has suddenly gone blurry which after 10 mins has passed. My skin is so dry. I drop things and my balance is sometimes off. My memory is rubbish - I forget things I've just read. I can't even remember if I listed all my symptoms to my GP.
I've not changed my diet at all and I am not vegan or vegetarian, although I don't eat much red meat. Until this year I was donating blood so I know my iron was acceptable (this year they tested and refused me as expected).
I finally had an follow-up appointment with my GP last week and she has given me iron and 5mg folic acid tablets. However she said my B12 is in range so that's nothing to worry about. Whilst it being in range is true is it near the bottom at 195 (150-99999) so should I still be concerned? Should I go back and push this? Any advice gratefully received.
Thank you all very much.
