RAI - Hashimotos?

I was diagnosed with overactive thyroid in 1990, after a hectic time had Radio-active Iodine in 1993 and 2 months later I was underactive.

I know there is nothing special about this, but over the years my Levo was increased as expected until 9 years ago and then my GP started to reduce, TSH was increasing, but then I started to get gut problems, I started getting skins conditions, I got treated for Eczema in my ears and told I had Celiac, then in 2013 had gallbladder removed.

Now here is my question...

Could I have Hashimotos?

I seem to be in a cycle of immune issues, I got told by my Endo that I could have HAD Hashi's or Graves before RAI, but as I no longer have a thyroid I would not. To me that does not equate, as regardless of radio-active treatment, auto-immune would not just stop, Surely it would be in my interest to check?

Please advise me, I am battling with this and sometimes I loose all my oomph, and then depressed, to start the cycle again.

Can you post your recent thyroid results with the lab ref ranges (the figures in brackets after your results). I'm concerned that your GP was reducing your dose although your TSH was rising. TSH rises when the body is short of T3. Levothyroxine should be increased when TSH rises.

My understanding is that without a thyroid to attack Hashi becomes dormant unlike Graves which can attack other organs when thyroid is ablated.

Having one autoimmune disease does predispose one to others and there is a school of thought which thinks that all autoimmune disease starts in the gut which is why dietary changes can improve and reduce flare ups in autoimmune diseases.

You can order private antibody tests if you want to check your status

These are what I have for the last year, but nearly all of these TSH are low, and the ones for the previous year were also. I don't seem to be able to find any previous.


Addi, Your TSH set point can remain low for years after being hyperthyroid and sometimes never recovers. Your FT4 is currently low because your FT3 is high so there is no requirement to store T4 for conversion to T3. I would hazard that you are slightly overreplaced with your FT3 above range. If you have any hyper symptoms you might be more comfortable if you reduce your dose very slightly. Are you taking T4+T3 or NDT?

Were you prescribed D3 for your vitD deficiency?


I only started taking T3 with my Levo in May 2014, my T4 has been upper range for what seems forever, I have been requesting Free T3 bloods every time, but only had done a couple of times and on the last one it was high - due I am sure to my taking T3. I had asked to do Totals to see how the ratio was for my Triodothyronine, but found out GP could not, but she has been so helpful, she went ahead in getting me set up to see an Endocrinologist with the intentions of the tests she could not put through being done, unfortunately he is not to my liking, (have only seen him once at the beginning of July, and go to see him again in September as he wanted to see how I go on the T3), as he put down a lot of things I was asking about, he even managed to use the term "hippy dippy" when I brought in my DAT's as I have been really fatigued for the past 8 months, I have pulled away from social interaction as I get so angry/irritable, I have become more aware, (squinting in discomfort) of light, along with a multitude of other things going on, and my GP agreed that it could be adrenal, but again was unable to do 24hr saliva test.

Yes I was told to get D3, as well as folate and B12, the GP only prescribed Ferrous Fumarate...

These are ALL of what I have added into my supplement regime:

Thyroxine REDUCED 150mcg -- 28th June 2013

Holy Basil Leaf 400mg (2 x 2pd) -- 9th July 2014

Mega Benfotiamine (B1) 250mg -- 9th July 2014

I do not know if they all help, I know my folate, iron, B12 are slowly rising, so at least they are being beneficial, but I still worry about absorption, and I cannot stop and wonder about whether my T3 is where it is meant to be and not just running around unbound like me in

(poor attempt at humour, feeling anxious!)

Also, still concerned about my adrenals, namely cortisol levels, I look at my WBC and they seem to get lower each time, I know it is not indicative all by itself, but with other symptoms, my DAT's, and this as the only thing to look at, it seems I may have a cortisol issue, the endo said that the saliva test was too expensive, (I know it is not and will be getting private kit), he also said in his opinion urine test was better suited and more reliable. I am not a doctor, but I can research and do, and everything says that the saliva test is the best option.

I am sorry to rant on, I am glad I am typing this as I am crying and would probably have shut up if in person, so many times I just feel it is pointless to even ask.


Addi, your symptoms of tiredness, anxiety, irritability and tearfulness may be due to overmedication. Was your T4 reduced before you added in T3? You are taking the equivalent of 225mcg T4. FT3 is good in the top 75% of range but not over range. I think you need to decrease your T4 to 125mcg and halve your T3 to 12.5mcg for a few days to let your FT3 drop into range.

I assume DAT is temperature readings? Modern doctors probably aren't taught about basal temperature and metabolism so don't be upset by his ignorance and attitude.

Take 500mg-1,000mg of vit D with each dose of ferrous fumarate to aid absorption.

I don't understand cortisol and adrenals so can't advise.



Thank you so much for you advice, I do not understand where you got " You are taking the equivalent of 225mcg T4." ??

As I am on 150 mcg thyroxine, should I reduce to 75mcg? and then T3 to 12.5 mcg?

I take 2 x 2000mg Vit D seperate to my iron, and 400mg Vit C with each dose of Ferrous fumerate, so should I change this?

And yes, DAT is Daily Average Temperature, of which mine is all over the place, I understand this is one of the things only recently being monitored, I hope I am not jumping the gun, I just want to try and get to a "normal" state of mind, loose some weight and generally feel more like the person I was 30 years ago, I know I cannot be that person anymore, but I think I should be able to improve if I do all I can and get GP/Endo that helps... Oh and of course, valuable help from kind people such as yourself.



Addi, T3 is 3 x stronger than T4 so 25mcg T3 is equivalent to 75mcg T4 plus 150mcg T4 = 225mcg equivalence.

You should reduce T4 to 125mcg and temporarily reduce your T3 to 12.5mcg for a few days to allow your FT3 to drop and then increase your T3 to 25mcg if you need it. FT3 wants to be towards the top of the range but not over.

Your supplement regime is fine and doesn't need changing.



OK, thank you for clearing that up, I knew the strength of T3 but did not realise I should be adding it in T4 relation. I will drop dosage tomorrow and keep at that level and hopefully get a sense of improvemnet.

I will post on here next week and let you know how it goes,thank you so much for your help.



You're welcome, Addi.


Well hello Clutter,

It is now nearly 3 weeks since we spoke, I did as you suggested and have to say felt an improvement, but due to some extreme stress in the family at the moment, things seem to be falling apart.

I seem to tolerate 125mcg T4, and 25mcg T3 quite well, but as I have just had the worst 2 weeks of my life, cannot honestly say whether my bodily reactions are due to meds or the stress? I go for a full blood panel next week and am doing the 24 hr urine collection for next week as well, so hopefully can get a clearer idea when the results are in.

Just another quick question, how much can extreme stress skew results? I know it is relevant to say each person reacts differently under stress and it would be an individuals level of more or less to get to a reference point, but let me just reiterate, I have been in total despair, not an exaggeration, my 2 eldest daughters both stopped eating and drinking, one is now home and the other has gone on to a eating disorder unit, but by no means resolved and now a long road of recovery for both of them. So, I cannot help but wonder if my weight loss, anxiety, tiredness is symptomatic predominantly to that?


Addi, I'm glad the slight reduction helped. I don't know whether or not stress affects thyroid bloods but don't forget you shouldn't take your thyroid meds until after your blood draw.

I'm sorry to hear how stressed you are coping with your daughters' eating disorders. Perhaps you can you have family counselling to help you care for them and manage your stress at the same time.
