So I have hasimotos, that I didn't realise I had. I'm sure I asked the endo and he said no point now you're being treated. Weirdly I have found a tpo test in my records with no range of 150, don't know how I've overlooked it, except for brain fog.

I took my night dose of 6.25mcg T3 thinking it would be OK 12 hours later. But Obviously not.

So the GP keeps dropping levo on instructions of endo and I feel worse but again they can't get past the low tsh, it's all the endo has been interested in for 2 years.

Now I have a nurse practitioner to deal with. Who is trying. After sending me for ACHT test (that was a waste of half a day) she has now written this to endocrinologist

"Patient reluctant to reduce dose of thyroxine as he becomes symptomatic. I would be grateful for your expert opinion and a management plan going forward. Thank you."

His response:

"he is at risk of cardiac complication and osteoporosis the dose of thyroxine should be reduced. His symptoms are not thyroid related as he is over replaced TSH has been supressed for a couple of years and it had proved hard to convince him to reduce the dose of thyroxine"

I think that's usual scare tactics from reading past posts.

So after phone consultation with her, it's a 25mcg drop in levo and the pharmacy only has teva in 25mcg when I'm used to record, hoping I get on with that on top of the drop.

So prior to that, I have been reducing the T3, because in the back of my mind I never took the levo past 150mcg and didn't get the vitamin D optimal.

I had worked up to 150mcg levo and 12.5mcg T3 at night and 25mcg T3 on waking, but was crashing energy wise at 5pm, so split the 25mcg to waking and mid afternoon which helped a bit.

So I can't recall ever having any noticeable issues with taking T3. I was running and triathlon training in 2016. But it wasn't easy at all. Didn't really loose that much weight and body temp was in the 34's.

On the 150mcg levo and 37.5mcg T3 my results were both in the top end of the range and while I wouldn't say I felt normal, I felt better than I had in quite a few years. It was only when they insisted on lowering the t4 I felt bad. Now the T4 isn't returning to the same level. Which is making me wonder if it was the hashimotos adding to that?

I would say my main symptoms are fatigue, constipation, brain fog, tinnitus, weight gain, low mood and low temp. All worsen when I lower T4.

I've been trying to improve gut function with homemade kefir and apple cider vinegar with meals, I now use HCL. As I did the burp test and nothing happened. Couldn't get vitD above 57 on the 1600iu the endo prescribed. So I have been taking 5000iu sublingual vit d. Doctor wouldn't retest, but has agreed too on next test along with vitamins.

So there's a lot going on. I'm not sure if I should continue with the T3 reduction as well as the levo. I think ultimately it needs to lower as I am very gradually losing weight when I think I should be stable.

I'm going to write to the doctor and ask to reduce the T3 and reinstate the T4. I'm not sure why the endo thinks the T4 reduction will increase my TSH (because it hasn't done previously). Unless that's all he knows and doesn't usually treat his patients with T3, or by reducing T3 would it look like he was over medicating me? Who knows.

I feel like his comments were more a poke at me for not accepting his treatment recommendations. Is the ongoing treatment plan to just continue lowering levo?

Sorry if all of that's a bit scatty my head is a mess with it.

I think I'd like to refute the cardio and osteo claims with some research papers.

Anyone come back off combo therapy and got T4 to work, I really wanted to try NDT but it sounds like that is a nightmare for people at the moment and there's no way I could afford to do it privately.

Will my TSH rise again after being suppressed for so long?

Does conversion go on regardless of TSH, its just that your Thyroid won't release T4 with it suppressed?

So I theory if you put enough T4 in and have optimal conditions you'll get conversion to T3 and the TSH not recovering won't be an issue?
