I was diagnosed with hypo following a partial thyroidectomy approximately 3 years ago I am on 125mg of levothyroxine and find that I have a problem with fading out of conversations for seconds where my brain seems to shut down or go to sleep. Very awkward as my job is customer facing. I'm pretty sure that my doctor will just test me for diabetes yet again as they take one look at my weight and assume that is the problem. I'm pretty sure that my thyroid problems started long before the op but was never diagnosed as I never used to go to the doctors. What should I ask him o test me for to get this problem resolved

  • Hi

    Sorry you have had no replies - you may find you get a better response if you post things like this as a Q...

    In the meantime - VERY helpful info here:




  • Thanks am new to site so will remember this for my next question

  • Not sure I can give you an awful lot of advice about this problem, but since my sub-total thyroidectomy in 1981 I have had this problem. Was not treated at all for 16 years and this problem was terrible. It has improved slightly since being treated in 1997, but I think there is room for improvement in my treatment, which is 75 mcg Levothyroxine only. Janet.

  • A problem shared they say, it i a relief to know that others are aware of this.I was imagining all sorts and I have vivid imagination so thank you for sharing this with me I shall tackle my doctor more readily now

  • Blood test results when you get them, with any past history would help with comments.

    The brain is first in line for thyroid hormones takeup so maybe you're ingoring the physical fatigue too much and pushing yourself?

    As you say it may be something else [even age ] - but many do report blank spells with UAT.

  • It is reassuring to know I am not alone, My husband thinks that I do too much so it i one thing to consider. I am so glad that my friend recommended this site as I have been plodding on thinking there wasn't much I could do. My doc. Thanks for the repliestor will be besieged with questions from now on

  • Thyroxine (T4) is the inactive hormone and liothyronine (T3) is the active one. T4 should convert to enough T3 but sometimes i doesn't.

    Every cell in our body (billions) need T3 for us to function and the brain contains the most.

    Ask your GP for a T3 blood test (some labs wont do it if TSH is in range) but you can get a private T3 blood test from one of the labs here:-


    Blue Horizon do homebloodtests.
