My recent FT3 test shows my T3 over range. I am seeing my Endo next week, and fully expect him to have a hissy fit when he sees it lol (if I tell him)
After a few years of hypothyroid symptoms despite good T4 levels and low TSH levels (on 225mcgs Levothyroxine/day), I added T3 to my medication myself (25mcgs/day). The results have been amazing, all my Hypothyroid symptoms have fully gone after 8 weeks of T3. Quite shocked at how good I now feel. Below is todays blood results (patient feeling good):
TSH: <0.01 mIU/L - Range (0.27 - 4.2)
Free Thyroxine: 22.3 pmol/L - Range (12 - 22)
Free T3: 7.7 pmol/L - Range (3.1 - 6.8)
Blood results from 8 weeks ago prior to addition of T3 (patient feels terrible):
TSH: <0.01 mIU/L - Range (0.27 - 4.2)
Free Thyroxine: 23.1 pmol/L - Range (12 - 22)
Free T3: 5.5 pmol/L - Range (3.1 - 6.8)
Patient history is 25 years since Hypothyroidism diagnosed and treated. All good until dose reduction in 2014 (T4) which caused hypo symptoms, dose reinstated a year ago but no recovery from hypothyroid symptoms until T3 introduced recently. Vitamin D, B12, Ferritin all at good level.
Question:
I have no symptoms of over medication at all at present (well not yet) and wonder if it is best to reduce T3 and feel unwell, or stay on current dose and risk health issues (if any) and the obvious wrath of my GP/Endo lol

Thanks Greygoose. As others have advised reducing T4 instead of T3 i was planning on dropping T4 in stages to probably about half my current dose hopefully with testing at stages. Guess this will bring T3 down too?
I have a different viewpoint, in that the blood tests were introduced for the use of levo alone. Therefore, if we add into the mix T3 or NDT the results wont correlate.
This doctor was concerned only on his patients' wellbeing.
I think I'd be minded to reduce my levo dose rather than my liothyronine dose. Try reducing the levo dose by 25mcg. That should bring down FT3 and FT4. It's probably the liothyronine that's made you feel so much better.
Yes, if you like the T3, then why not reduce T4? I was on T3 only for nearly fifteen yrs as cannot convert and the only way to keep my tsh within range was to have high T3 levels - always between 7-9 with no adverse symptoms. But my T4 was very low and tsh between 0.7 and 1.5. This never seemed to cause me any issues and was the only way to feel reasonable but I had lot of other problems and systemic inflammation at the time meaning I probably had difficulties utilising the T3 or some form of resistance. Since these other issues have cleared up, I've become extremely hyper and sensitive to high levels of T3 and can no longer cope with them. However, you're tsh is suppressed probably meaning that you shouldn't be on such high levels either
Saw my Endocrinologist today, and he is confident that I have an issue with my thyroid receptors in my body cells: not absorbing T3 well. Plenty of hormones in blood but Hypothyroid symptoms in patient.
He is not sure what caused it over 3 years ago, but it explains all the odd blood results over that period and the remarkable recovery after my addition of T3 to my daily medication recently, which he was happy with and would have suggested same treatment.
After an examination of me: pulse, blood pressure, looking for hand tremors, etc, he agrees with what is discussed here: I am slightly over medicated.
He suggests reducing both T4 by 25mcgs/day and reducing T3 by 12.5mcgs/day, Retest in 8 weeks, and back for consultation. Bone density scan booked for 12 months time too.
As he said, no idea what caused it but easily addressed with self medication of T3.
I may have to research thyroid resistance myself too, as I believe everyone should own their complaint Unless, anyone wants to chip in here with any helpful info.
Thanks again all, dont know how i would have coped over last 3 years without my team: you guys
Well the reductions in either and/or both in various steps ALL led to Hypothyroid symptoms The only way I feel well is with both doses as before and T3 being over range Got a DEXA scan tomorrow, and then will be back to see my Endo to see whats next. Folate, ferritin, B12 and Vitamin D all good as were checked first
I am on no medication for thyroid. Have had hashi type symptoms for years. Have a mirena coil and use estrogen gel topically.
My t3 is 7.5 (range 3.5 - 6.2)
How can I be sure what is measured in the blood is getting to the tissues/organs?
Is it true too much t3 causes weight gain because I have gained a stone since replacement mirena 20/12/2016. (My other levels are in my earlier info)
Doc not bothered about above range, I still have aching, fatigue, anxiety, dry skin and hair, palps, cold/heat intolerance, tinnitus, muscle and joint pain, disorientation,, (eye twitch since anesthetic for hysteroscopy and new mirena).
Can't find an answer on the net for naturally above range T3, only med related. Can anyone help please?
Maybe start a new post for this question so more will see it?
I have no idea myself on naturally raised T3 sadly as mine was down to medication. However, mine was 7.7 and my endocrinologist didn't really panic at it, just suggested we should try to get it within range.

Updated results - not sure what to do next?
Help understanding Thyroid results
Should I worry about T3 being above range?
Advice please, do NHS endocrinologists ever prescribe T3?
DIO2 and when to ask for T3
