Hey, I recently posted about fluctuating t3 but actually it’s been pretty consistently high whenever I’m on 90 mg or Armour, plus 75 synthroid. (That decision was made a few years ago when just t4 didn’t work, but just NDT didn’t work either. ). The past couple of blood tests have shown a t3 of 5.3-5.6 but ref range ends at 4.4. I used to feel good on this but the past couple of weeks I experience breathlessness especially in the morning, lightheadedness, feeling week. Not right away when I get up, but later in the morning. So prob when t3 would be at peak value. T4 is consistently normal and tsh very very low.
Anyone else had these symptoms with over treatment? I do not have a thyroid anymore. Had a huge goiter.
How soon can I expect symptoms to become less after adjusting meds? And it seems like my body doesn’t like the short half life of T3 anymore, go back to synthroid? Insurance covers brand name.
Ive read that the half life of T3 is about a day, but peak concentration usually occurs between 4-6 hrs. Which would coincide that I feel worst second half of the morning, then afternoon is fine and evenings Im tired.
But would you know if my T3 levels would be sufficiently high to cause trouble? Ihave been checked for other conditions like heart disease, electrolyte imbalance etc.
Well, they're not that high. I don't think they'd cause me any problems. But, we're all different, so difficult to say what would cause a problem for someone else.
The half-life of T3 in the blood is 24 hours. But, in the blood it doesn't do anything, it has to get into the cells to have an effect. And, the T3 in the cells stays there for about 3 days. Also, peak concentration depends on when you take your exogenous hormone. T3 produced by the thyroid is highest early morning.
Have you had your nutrients tested? Vit D, vit B12, folate, ferritin? Low nutrients can cause breathlessness and light-headedness.
Once your cellular level of T3 is optimised then I doubt the half life of T3 will be a problem because the optimal dose should provide the adequate and constant supply that the body needs
Recovery is a long slow process I'm afraid, unlike taking a tablet for a headache.
