This forum pops up a lot when googling, so I thought I'd take the liberty of asking my own question, since there seem to be some knowledgeable members here.
Basically, I've been trying to find a reason for my "non-specific" symptoms for years now, which look something like below. I have a history of stress and horror nutrition, which I've addressed successfully over the last 18-months with, incredibly, absolutely zero results. Before that I went the usual routes through the NHS, physiotherapists etc.
- Carpal tunnel syndrome (debilitating)
- Cold hands and cold intolerance
- Fatigue and brain fog/low concentration
- Trouble getting to sleep and getting up
- Irritability
- Underweight (5'10", 60kg) but still have stubborn belly fat
- GERD, bloating and sluggish digestion
- Hair loss inc. thinning eyebrow
- Reduction in libido
- Palpitations/night-time adrenaline rush (recent one)
It occurred to me that a lot of these are consistent with hypothyroidism, so I got a full panel done.
TSH 1.20
FT4 14.3 (10-22)
FT3 3.3 (2.8-6.5)
RT3 0.39 (0.14-0.48)
FT4/FT3 4.3
RT3/FT3 8.5
Antibodies well within range
I'm no expert, but the ratios seem pretty bad, despite everything being "in range". I've researched what I can, and have focused nutrition further e.g. selenium, more protein etc. Stress isn't a problem any more, I don't do cardio, I don't diet or go hungry and keep blood sugar stable, I eat something carby around bedtime... I'm not sure what else I can do to lower RT3.
I began experimenting with sub-physiologic doses of T3 (2mg every 1-2 hours) based mainly on pulse and mental cloudiness. That kind of dosing is too haphazard though, and I ended up taking up to 18mg/day which I think was too much and made my palpitations worse (didn't feel hyper at all though). I did build up from about 1-3mg/day over 2-weeks, and I noticed improvements in energy, cognition, temperature, pulse etc before the palpitations.
I'm certainly not asking for medical advice, but I'd really like to hear people's thoughts on (general) treatments for high RT3/low T3. Maybe there's some conversion factor I'm overlooking, and maybe T3 or even combined meds can be a temporary part of the process. Maybe my labs are actually fine and I'm insane for taking T3? Any help would be much appreciated. Thanks in advance.
