I've been on thyroxin for about 28 years on 250 mg about two years ago after blood tests doctor reduced to 200 each test since has been reduced I'm now on 100 mg over the 2 years I've pun on 2 stone in weight tired cold and have muscle weakness.
Recently have had my medical records and on the blood tests is says I'm NOT on thyroxine would it make a difference to the results
philvaughan, can you post the numbers from your most recent thyroid test? That will help us to answer your question more appropriately😊.
free t4 30.9 tsh 0.02
FT4 30.9 is extremely high!
This is whilst taking 100mcg levothyroxine a day? If yes, how long before the blood draw did you take your last thyroxine dose? And what time of day was the blood draw?
no 150 mg blood taken am about 12 hours i think
it says on report only relevant if NOT on thyroxine
So, if you took 150mcg levo around twelve hours before the test, and the test shows FT4 30.9, then your levothyroxine dose is far too high.
If you were not on thyroxine, those test results would imply you are hypERthyroid.
But you are on levothyroxine, which means you are taking too much.
This certainly could explain your symptoms. Yes, you can put on weight, feel cold, tired and weak when over medicated with levothyroxine.
thank you
Having had dose levothyroxine reduced over recent years……it’s likely you may have low vitamin levels
On Levo it’s ESSENTIAL to test and maintain GOOD vitamin levels
What vitamin supplements are you taking
When were vitamin D, folate, ferritin and B12 last tested
Please add most recent results
Testing thyroid levels it’s ESSENTIAL to test TSH, Ft4 and Ft3 together
Approx how much do you weigh in kilo
Guidelines suggest approximately 1.6mcg Levo per kilo of your weight per day
Do you always get same brand levothyroxine at each prescription
Do you always take Levo on empty stomach then nothing but water for at least hour after …..no other medication or supplements within 2 hours.
Is your hypothyroidism autoimmune?
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
