These are my labs pre T4:
TSH: 3.14 (0.40-4.50 mIU/L)
T4, Free: 0.9 (0.8-1.8 ng/dL)
T3, Free: 2.3 (2.3-4.2 pg/dL)
That is while on 150mcg T4.
TSH: 0.03 (0.40-4.50 mIU/L)
T4 (Thyroxine), Total: 4.8 (4.5-12.0 mcg/dL)
T3, Total: 50 (76-181 ng/dL)
I know I should have had free levels and RT3 checked. My doc wants me to lower my T4 dosage due to the TSH levels which seems counter intuitive given my T4 and T3 levels but reading the following…
Most people are able to convert T4–>T3 in peripheral tissues. But some cannot. When those few are on T4 meds, they can have hypo symptoms, some times severe. And when thyroid meds are used and TSH is pushed low or to zero, T4–>T3 inside the thyroid is reduced or stopped.
As you can see from the above, how people react to thyroid meds can be highly variable. There is no single cookie cutter med or protocol. Many doctors are not mentally equipped to deal with this. And the drug reps push their T4 products and tell docs that that is all that is needed because the patients will convert T4–>T3 on their own. While that seems to be true in many cases, this creates hell for some patients.
Drug reps selling T4 are in competition with things like Armour Thyroid and have a dialog telling doctors that Armour simply has no reason to exist now that synthetic T4 is available. Some docs have learned otherwise.
Then with combined adrenal fatigue and hypo symptoms, docs will treat the hypothyroidism with T4 and that will increase T4–>rT3. Then rT3 blocks more fT3 and hypo symptoms can get worse. Again, this is a degree of complexity that many doctors are not able to grasp.
If someone has the combination of issues in the above paragraph but also lacks the ability to properly T4–>T3 in peripheral tissues, then when put on T4, T3 production will be low and increasing rT3 will make that much more severe by blocking the action of what fT3 they have.
All of these things can be at play at times in a doctors case load and this can create very confusing situations where it is difficult to know what is going on. And the doctor might assume that the symptoms must be from some other pathology and not be thyroid related, because the patient has been properly medicated for that.
I find that I am not equipped to deal with these issues in a forum.[/quote][/i]
Do you think this is the issue with the following blood work?
The thing is, I am now taking T3 directly and my levels are well above the normal range but I am still often tired (I am dieting so maybe that’s why) and my morning temp is ~97.0. But my morning heart rate is close to 100! It is usually 55-60.
