Low FT3/FT4 (hypothyroidism) low TSH on LT4 dosage

[sharkoon008]

Good morning everbody,

Im 27 y. old, 80kg, 12% bf.
I´m hypothyroid and and have hypogonadism. I´m on a HCG-Monotherapy.
I think that my thyroid gland is not yet functioning properly and therefore my testosterone synthesis is also limited.
When my metabolism is better again, the HCG therapy will also work better.
Especially the Ft3 values make me think.

Starting FT3 was: 1,3 pg/ml (2-4,4) and also lowish FT4. TSH was around between 2-4.



I started the treatment with L-Thyroxine 25mmc then 50mmc then 100mmc...

TSH was everytime around ~1 and I was getting better piece by piece.
Then I increased the LT from 100 to 112.5 and see the result.

Is a low TSH under substitution a problem at all?
I would like to know if you would increase L-thyroxine, since both free levels are still low.

Ultrasound of thyroid gland was done, volume was much too small.
(thyroid gland with echoric, homogeneous parenchyma and
inconspicuous vascularization. Volume right 3.6 ml; volume left 3.5 ml).

Antibodies have also been measured, also again before starting with L-thyroxine.
All minerals were tested, selenium, iron, B12, vitamin D, iodine -> no deficit

From my understanding, T4-only treatment is often questionable at best. Others here are better versed in thyroid and hopefully will chime in.

can cytomel by itself be used to treat hypothyroidism

I'm just wondering if anyone uses just Cytomel (Liothyronine) to treat their hypothyroidism?

I don't think you can use just T3 (Cytomel only) to treat hypothyroidism as 95% is totally absorbed in 4 hours. You would have to continually take it every 4 hours. Some will use an NDT product + a T3 product (Cyromel/etc.)

It takes two things to convert T4 to T3. Good cortisol levels and good iron levels. You need to get a 24 hour saliva cortisol test and have all 4 iron labs (TIBS/%saturation/ferritin/serum). You need to have "optimal" levels not just "average" and/or "in-range". I would also get on a NDT instead of the synthetic T4. With that being said once you get your cortisol/iron levels up and you start converting to T3 you "may" do OK. Some do some don't. If your doc is only going by TSH levels you need to find another one or start doing some research on your own. Watch your RT3 levels as if you don't convert they will climb. A very good research is STTM (Stop the Thyroid Madness). They even have a Yahoo discussion board. Very knowledgeable people. Jamie Bawthorpe has also written two books.

Yep that’s what the thread is about. You can’t use cytomel only To treat hypothyroidism.
