low tsh

[SYLVIE15]

hello i am asking for some of the well informed to help

my last reading of underactive thyroid is

abnormal on tsh = 0.33 mlU/|L range .38-5.50

free t3 =4.7 pmol/L range 3.5 -6.5

t4 = 15.5 pmol/L range 10.0 -18.7

if the tsh is low is it an increase in thyroxin or a decrease

this test was done 10 days ago and the surgery have not contacted me

if my throid is out of sync i develop angioeadeama and had have this for 4 months

my surgery is rubbish and i am left high and dry with no where to go

thankyou Sylvie 15

Hi there Sylvie.

TSH is a bit of a red herring. It's a message from the pituitary to your thyroid gland to tell it to work harder or not as much. I know that GPs are obsessed with it, and use it as their primary diagnostic tool, but once you are on meds it is pretty well irrelevant - because your thyroid isn't actually doing all the heavy lifting at that point - your meds are assisting.

What matters are your actual thyroid hormones - so your free T4 (63% through range) and your free T3 (56.7% through range) - and how you feel.

Your results are in the top half of range, which is good - although lots of us like it higher still (without going over-range). So if you don't feel tip-top, I'd suggest asking the GP for an extra 25 mcg of levo, to bring your free T4 and free T3 up a bit. It's unlikely they will contact you (unless it's to moan abut your TSH - because your frees are ok)

If the jargon is getting you down, have a good rootle around the Thyroid UK site - and helvella 's excellent glossary - which is a "pinned post" - click on "posts" at the top of the page and then "pinned posts" - and read the posts and answers.

Good luck x

Either or neither. Your thyroid hormones are still rather low in range, and your TSH hasn't read the textbook that says that it should reflect that. If you still have symptoms, your thyroid hormones suggest that you might need a 25mcg increase in levo, but many GPs are obsessed with TSH and so won't do it. If you feel good, your dose is fine and shouldn't be messed with.
