I'm a 40yo male, 6', 144 lb
I've always been thin/underweight but also always had hypo thyroid symptoms: cold hands/feet/nose, fatigue, anxiety. When I found Ray Peat's ideas about 2 years ago I implemented diet changes but only found minor change in these symptoms.
My pulse and temps were lowish at this time: 97.2 F and 60-64 bpm. I decide to give thyroid medication a shot and in July 2021 I started taking Cynoplus... 1/8 tablet, then slowly working up to 3/4 tablet over three months. I now realize that was a lot and probably went too high.
The Cynoplus improved my pulse, probably too much, to 90-95 bpm upon waking. (My pounding heart was making me uncomfortable) Curiously my temps did not rise that much, only to 97.6ish.
I tapered off Cynoplus completely in November due to feeling uncomfortable with headaches and pounding heart. So it's been about 4-6 weeks since stopping and my pulse is still high (for me) 90-95 bpm.
Just got a thyroid panel and everything is outside normal ranges:
TSH: <0.01
(LOW - range 0.40-4.50)
T3 uptake: 40
(HIGH - range 22-35%)
T4, Total: 19.3
(HIGH - range 4.9-10.5 mcg/dl)
Free T4 Index (T7): 7.7
(HIGH - range 1.4-3.8)
Can anyone help me interpret what it means? I understand it mean HYPERthyroidism but what does it mean in my context of a history of hypo symptoms and taking Cynoplus for 4.5 months. Is my body not able to use the T4?
The T4 values are alarming because they are so high (double the high reference range) and I'm worried about occasionally chest pain I'm having. I just read that high Free T4 puts you at higher risk for heart attack.
