Blood results, free T3 , help please....

[cal1971]

I had a whole raft of blood tests at the endo and after having looked through, these are probably the most important. The endo says everything is fine, gave me a spiel about taking too much levo and being suppressed ( TSH of 0.59) I might get osteoporosis.

I have to go back to my Doctors so wondered what my next move should be.

Thanks in advance.

THY PYROX AB 91 / IU/mL / Range 0-60

lgA tTG ab <1.9 / CU / Range 0-19.9

FREE THYROXINE 12.8 /pmol/L Range 9.0-19.0

FREE T3 3.7 pmol/L / Range 2.6-5.7

I forgot to mention that I am on 125mcg Levo with 150mcg twice a week ( don't ask!!)

Cal1971, Not sure why you should be lectured about suppressed TSH. TSH 0.59 is within range. TSH <0.1 is suppressed. Free thyroxine (FT4) 12.8 is very low in range, ideally it will be in the upper range to enable good conversion to T3. FT3 3.7 is low in range. Read Treatment options in thyroiduk.org.uk/tuk/about_... Email [e-mail] for a copy of the Pulse article if you would like to show it to your GP or endo if you are symptomatic and want a dose increase.

Recent research published finds no association with low TSH and development of atrial fibrillation or osteoporosis.

I know, I did try and look concerned when he told me about osteoporosis knowing it was rubbish, I think he just wanted to cover his own back!!!

I am also being a bit dim as my TSH actually HAS been suppressed for a long time and now it seems to have gone up again.....!! Sorry about that. T3 and T4 being low I might go for an increase in levo although my Dr seems receptive to the possibility of adding T3 so i will see how it goes. Thanks!

Cal1971, instead he looks like he doesn't keep up with research or is an alarmist fool!

[patdo in reply to Clutter]

Is it possible to know where I can find the research you mention re low TSH and atrial fibrillation and osteoporosis please?

Patdo,

The conclusion of the first states:

"There is an increased risk of AF with higher FT4 levels within the normal range, especially in younger subjects. Adding FT4 to the simple model slightly improved discrimination of risk prediction."

Not sure we can use this in our arguments!

[Treepie in reply to hose1975]

True but they go by TSH and it does say TSH levels were not associated withAF

[hose1975 in reply to Treepie]

Happy days!

[Clutter in reply to hose1975]

Hose1975, The point is the study finds no association between TSH and AF. If you read on it suggests that AF/higher FT4 was found in unmedicated subjects as there is a suggestion that there should be a further study to see whether the same is found in patients on replacement therapy.

[cal1971]

What about the THY PYROX AB 91 / IU/mL / Range 0-60, is that not a concern unless it is way off?

[Clutter in reply to cal1971]

Cal1971, it means you are positive for autoimmune thyroid disease (Hashimoto's) which has caused your hypothyroidism. 100% gluten-free diet may reduce Hashi flares, symptoms and antibodies but you may have to stick with it 6-12 months before you see much benefit.
