Low T3 and T4

I've been to my doctors to discuss my lastest blood results for my under active thyroid. And I've been told they are normal. After receiving some great advice on my earlier post I mentioned my concerns to the doctor but this fell on deaf ears. I told the doctor I was concerned about low levels of free T3 and t4 but this fell on deaf ears. I've asked for a private referral to see an endocrinologist.

  • Tldg45,

    If you are taking Levothyroxine you are under medicated. If you do not yet have a diagnosis NHS won't diagnose until TSH is over range or FT4 below range.

    Email louise.roberts@thyroiduk.org.uk for a list of member recommended endocrinologists.

  • The doc has increased my thyroxine to 125mcg, my serum free t4 is 12 (9-23) and serum free t3 is 3.7 (3.5-6.5). My doctor didn't seem concerned about these levels yet I'm still feeling exhausted Thanks I'll email Louise.

  • Tldg45,

    How long ago was dose increased to 125mcg?

  • 7 weeks ago, it hasn't been above 15 in years

  • Tldg45,

    If the results you posted were 7 weeks after dose was increased to 125mcg you are still under medicated and dose should be increased again to 150mcg.

  • Your doctor isn't concerned because both FT4 and FT3 are 'in range' which isn't sufficient for us, both should be towards the top, not bottom. Many doctors think once we reach anywhere 'in range' we're on sufficient hormones, that's why we have this forum because then we'd all be very well indeed and not searching for answers and we educate ourselves as many doctors aren't.

  • Tldg45 In your first post a few days ago you gave your results as

    TSH - 3.2 (0.55 - 4.8)

    FT4 - 12 (9 -23)

    FT3 - 3.7 (3.5 - 6.5)

    and you were advised your TSH is too high for a treated hypo patient, as well as your free Ts too low.

    Did you email Louise for the Dr Toft article to show your GP as suggested by Clutter?

    If you are going to pay to see an endo privately then you don't want to waste your money. Most of them are NHS endos who also do private consultations but stick to NHS guidelines. Email louise.roberts@thyroiduk.org.uk for a list of thyroid friendly endos, see who is in your area and ask for feedback from members before making an appointment.

  • Hi, I've emailed a Louise but she hasn't got back to me. I am asking to see an endo to see if my metabolic rate was low as to rule out having a gastric band. This was going to be my last resort as I'm at my wits end. If my metabolic rate was normal I'd know that a gastric band could help with my weightloss. Does this make sense

  • Doc increased my meds by another 25mcg today

  • Email Louise again, maybe it got overlooked.

  • Your FT3 is much too low for you to lose weight. You'd probably need it right up the top of the range. But, doctors have no idea about that sort of thing. If I were you, I'd buy my own T3, and self-treat - well, that's what I did, and the weight came off easily.

  • Where would I buy FT3. I have thought about it but need genuine drug

  • It's not a drug, it's a hormone.

    Put up a new post asking exactly that, and people will PM you their trusted sources. Sorry, I can't help with that. :)

  • Thank you

  • You're welcome. :)

  • Have done, thank you

  • CAN anyone message me about where to get t3 too...I am on nature throid and my test results were almost exactly as hers.....but my tsh was .04 at the bottom of normal on range....but dr said it had to be other hormones since I was low in estrogen and low in progesterone too so she increased those.....DOES that sound familiar to any of you?.......I am on 1.5 grains of nature throid. and she told me if she increased the dosage of nature throid that it would send my adrenals in over drive and I would burn them out. My dr is a holist dr and MD doctor....... She said either my other hormones are keeping ft3 ft4 low or something else....I had tested high cortisol in the last test...3 mths ago.... ANY THOUGHTS?
