TSH increased but no medication change

[Emj001]

Hi,

My recent blood tests showed my TSH has increased from 1.12 to 2.4 and I haven’t changed anything. Is there a reason this would happen or does it just fluctuate? I have been eating a lot of cruciferous everyday. Would that have an impact? My FT4 has remained pretty constant.

Please add Ft4 and Ft3 results

Plus vitamin D, folate, B12 and ferritin results

How much levothyroxine are you taking

Do you always get same brand levothyroxine

Were all tests done early morning, only water between waking and test and last dose levothyroxine 24 hours before test

Yes, TSH fluctuates, by the hour, illness, all sorts. This is why it tested more than once before a diagnosis is confirmed. Medically speaking, they call it ‘transient’. It’s a shame medical professionals are not adequately trained because if they did they check FT4 and FT3 to give you a true status of your thyroid.

Many do, but as I gather so many simply don’t.

No. As you're on thyroid hormone replacement, it wouldn't have any effect at all on your results.

Sorry off topic but I see in your bio that you have pigmentation changes did this occur after your thyroid surgery?

I also see you had thyroid cancer when is the last time you did Thyroglobulin test?
