Hi all....im new on this forum. I have joined because I literally have no clue about my thyroid disease. I was diagnosed as underactive in Sept 2003. I only found out as I was having trouble conceiving my 2nd child...had blood test done and the day I found out I was underactive is same day I found out I was pregnant. Over the years my meds have increased and up till December 2017 I was taking 175mcg levothyroxine. A recent blood test showed I was on verge of going overactive, so my GP TOLD me to alternate 175 one day and 150 the next and to do this for 8 weeks. I work in a hospital and got my most recent bloods while in work.
My results are :
Free thyroxine 16.5 (12 - 22)
TSH 0.66 (0.27 - 4.2)
Antithyroid Peroxidase ab 52 (<34)
Do i actually have autoimmune thyroid??
