Test results - is my thyroid ok? or what is my problem>

Hi everyone! I am 25, a female. I am very very confused about what doctors say, what I read, my test results and how I have been feeling...

I have been experiencing hypothyroidism symptoms for around 1-2 years, and they are getting worse as the time passes. I have been getting low-normal thyroid hormone results, but my tsh is always normal. Endo's don't prescribe me anything as low normal is normal for them even if I have symptoms. Meanwhile one of the doc's realised that I have insulin resistance (even though I exercise very well regularly) related hypoglycaemia and prescribed me metformin. I have been taking it for last 3 months. It doesn't help for anything, including weight control.

The last 4 months, for the first time in my life, I have experienced irregular and missed periods. I dont have PCOS or other gyneacological problems according to my gyneacologist. But he still wanted to see my hormones. Obviously my thyroid hormones, especially T3 are lower than 2 months ago. I insisted every endo on searching my pituitary functions and possible reasons why my thyroid levels are low, I tell them what I have read on articles - but somehow doctors react agressive to such approach from the patient.

I still believe the complaints I have are because of my low thyroid hormones. It may be euthyroid, less likely secondary hypothyroid, or low T3 syndrome which is not a purely thyroid disfunction problem. I have been reading a lot, believing taking my FT3,FT4,T3 and T4 to above from the mid range (to an optimal level) may help me. But I am so scared of self-medicating as all the endocs (4 famous endos in my country) were very very sure about I don't need a thyroid medication.

Could you please tell me what do you think about my results?

FT3 3.60 (range 3.10-6.80)
FT4 13.90 (range 12.00-22.00)
T3 0.75 (range 0.80-2.00)
T4 6.02 (range 5.10-14.10
TSH 1.30 (range 0.30-4.00)

As I said I have low thyroid function symptoms, and what I know is these hormones are optimal when they are above their midranges.

I also read that if RT3 is higher than 15 (in another source it says 12) it is not a good sign. My result from around 2-3 months ago is


RT3 18 (range 10-24)

Please help me! I am very desperate and tired of searching this, reading articles and visiting doctors. What should I do now?

Dear Astroman, thank you so so much for your reply!

I will consider the medication or natural supports you recommend. I guess I should start with a low dose. Seems like I am hopeless in finding an endocrinologist who can prescribe me something properly and advise me on dose.

I wil definatelly go and find old buddy's post and your reply

Yes right! I don't know how to react those doctors; should I laugh or should I be sad for both them and myself. Really, thank you very much for your support.
