Any Advice

Okay so been on Levothyroxine for 18 months with result coming down slowly whilst dose being increased. Continued to feel rough, tired, suffering severe depression levels at times, high blood pressure, brain fog.

Read about Hashimoto's Disease and ticked a lot of boxes and discussed this with GP after last TSH levels jumped.

Saw GP who has upped Levotyroxine to 200mg and put me on Folic Acid and doing another blood test next week.

I have quite a clear band around my neck, when I had a scan he said my thyroid was borderline enlarged but on the letter said I was fine. What do you make of my results? Especially the ferritin thats a worry, but strangely I was expecting my TSH to be higher because I fasted.?

Have you had thyroglobulin antibodies tested? TPO antibodies although in range are high.


Ferritin can be raised due to Thyroid, but I would ask GP to investigate further

Presumably you don't supplement iron?


Why no vitamin D test?

If you can't get one from GP
