You're very welcome. Yes, I have a conversion defect too, which is a pain to put it mildly
. I could never get on with NDT & my current Endocrinologist doesn't support its use, but he's collaborative & not dictatorial which is essential for me as I very much need to be involved in decisions about my care.
I think you're wise to reduce your T3 dose a bit to see how you feel & also because if we're on too much long term it's not good for the body (bones, cardiovascular system, kidneys etc). You should get an idea quite quickly whether less suits you better because as you'll know T3 doesn't hang around in the system for long, though I think it could take a while for your body to recover fully if you've possibly been on too high a dose for some time.
Although as you say hair loss can be related to sex hormone insufficiency or imbalance, we can also lose hair on the wrong thyroid dose over time. The skin can suffer too.
It's possible that HRT will have some effect on your thyroid requirement too, so a good idea to do a TFT 6-8 weeks after starting, again after any HRT dose change & of course, any time you suspect things are not right. As I'm still trying to balance the two, I'm currently having both sex hormone & thyroid levels tested quite frequently, but it does get expensive when the NHS doesn't like to test T3 for hypothyroid patients & we're not what you might call comfortably off
, so I sympathise with what you say about the cost of NDT being a consideration.
Whatever steps you take I do hope you'll feel better soon & that HRT will help.
