I had Graves 13 years ago so have annual TSH/FT4 blood tests.
Over the last few years my TSH has been creeping up and my FT4 has been sitting low in the range.
In view of my history of Graves, the fact I have other autoimmune issues (pernicious anaemia and vitiligo) and because TSH was 4.3 six months ago I asked my GP to test my thyroid antibodies.
I’ve just had my results (which show that TSH is better than recent years) and these are
Thyroid peroxidase: TPO result is positive
263.8 (range 0-5.6)
TSH 3.05 (0.35-5.00)
Free T4 11.2 (9-22)
I do feel more tired than friends of a similar age but usually assume it’s a B12 issue (which I’m happy is being adequately treated). Otherwise apart from hair loss over the last 6-9 months I feel generally well and my weight is fine. (The test 6 months ago did show that Free T3 was near the top of the range despite T4 being near the bottom).
My GP has suggested that subject to the latest test results that it may be an idea to start me on 50mcg thyroxine and I’m seeing him soon to follow this up.
Do you think that starting on thyroxine is a good idea even though my TSH & T4 are in range?
Are there any questions I should ask my GP?
Incidentally I did have a test for coeliac a while back and this came back negative.
