I suffer from Hashimotos as recent blood tests show I have high Anti-TPO antibodies at 41,000 (<34) and due to a very high TSH of 22 back in May last year I have been initially put on 25mcg of levothyroxine. However with my TSH crawling back up again the dose has been increased to 150mcg.
My next blood test is coming up - on the 20th January - and I'm sure the results are going to be abnormal again as I've not felt much better since taking the increased dose since October. How long would it take for the T4 to lower the TSH?
My dose has been as follows:
23 May-6 June: 25mcg
7 June-21 June: 50mcg
22 June-22 September: 75mcg
23 September-7 November: 125mcg
8 November onwards: 150mcg
My blood test results for thyroid function tests are as follows:
TSH - 0.69 (0.27-4.2)
Anti-TPO antibodies - 84,000 (<34)
TSH - 22 (0.27-4.2)
FT4 - 10.9 (12-22)
**** I was started on Levothyroxine with the above instructed doses in place up to the 75mcg dose****
TSH - 4 (0.27-4.2)
FT4 - Not done as TSH within range
Ferritin - 15 (30-400)
****Levothyroxine increased to 125mcg and started on iron meds****
TSH - 4.3 (0.27-4.2)
FT4 - 15.3 (12-22)
FT3 (done privately) - 5.5 (3.1-6.8)
****Levothyroxine increased to 150mcg****
TSH - 4.6 (0.27-4.2)
FT4 - 15.6 (12-22)
Ferritin - 21 (30-400)
Vitamin D - 43.6 (>75)
Vitamin B12 - 363 (180-900)
Folate - 4.1 (4.6-18.7)
****Levothyroxine not increased despite high TSH but put on Vitamin D meds - not started on folate/Vitamin B12 either****
I'm also considering adding Brazil nuts to my diet as they contain traces of T3 (sounds far fetched I know but this information is on a few sites that I've visited) - would they affect the overall thyroid function test result within 2 weeks or would this result not be seen as a true reflection of my thyroid function?
Thanks for your help.
