"...results challenge the dogma that treatment with LT4 for hypothyroidism restores TH homeostasis in all patients."
Participants continuously treated with LT4 exhibited a stable elevation in serum FT4 and, a reduction in serum FT3 and
TSH
levels.

Speaking to GP tomorrow - which symptoms should I emphasise
I think I am undermedicated with results: Serum
TSH
level 2.41 mIU/L [0.27 - 4.2] Serum free T4 level 16.7 pmol/L [12.0 - 22.0] Especially as I forgot and took my 50 levothyroxine an hour before the test (numpty) They are against me being on levothyroxine as I can't have any symptoms at that

Help, need your help
My
TSH
is .37 so I am low. Do I need to take a higher dose of Synthroid or a lower dose of Synthroid. I can’t remember how that works. My T3 and T4 are within normal ranges.

Almost 9 months post Radioactive therapy and still not feeling good
I am currently taking 50 levothyroxyn daily and per my endocrinologist my
TSH
should drop further in the next 3 weeks until he sees me again - Goal is to drop it to 1.50 where I feel the best.

Normal thyroid function and carbimazole
But my previous GP told me since my
TSH
free T3 and T4 are good I should just check regularly on my TRAb and that my thyroid function levels stay good and I shouldn’t have treatment unless they start going too high and low.

puffy eyes levothyroxine
I was taking 100mcg levothyroxine my blood test result was
TSH
4.36. Doctor advised to increase to 125mcg 4 days of week and 3 days 100mcg. I did that for first week to adjust as I could feel the difference in taking higher dose.

When to take Lio before blood test?
But now
TSH
is below range and my endo wants to reduce Lio, which will bring back symptoms. I currently take 15 mcg Lio + 75 mcg Levo, split into 5 mcg Lio at 11pm and 10 Lio + 75 Levo at 7am (1.5h before breakfast).

Sore, swollen lips; lethargy and weakness
When I was first diagnosed with low thyroid, I had low
TSH
, low T4 and low T3. Endo suspected pituatory tumor, but CT Scan showed all clear. My GP friend mentioned parathyroid issues.... anyone got any insight on testing etc for that condition?
