Guest guest Posted March 17, 2006 Report Share Posted March 17, 2006 Regarding rose11141 post: My doctor(Fibromyalgia and Fatique Clinic), just started adding T3 to my resume. HA!. I am taking .125 of levoxyl which worked well the first 3 months but seemed to actually quit helping me at all. I am up to 50 mcg which I can really begin to tell a big difference again. She said as we go up on the T3, we will probably need to cut back the dosage of levoxyl. my labs I went to the walk-in clinic instead of calling for the results of my labs, and the doctor decided he wanted to see me.I asked the receptionist for a copy of my labs and she kinda looked at me funny and told me I would have to ask the doctor for that.(Strange isn't that??I mean they ARE mine)I was on 0.1 mg of eltroxin and he told me that was too much so he lowered it to 0.088 here they are: THYROTROPIN (SENSITIVE TSH) <0.05 REF RANGE 0.35-5.00 FREE THYROXINE (FREE T4) 28 REF RANGE 9-23My question is,if my T4 is too high and my TSH too low its obviously not converting,right?So instead of just lowering my script shouldn't he have given me something that included T3?That would be the reason I'm so tired all the time and I've gained 40LBS in a year??Also,I picked up some brazil nuts because they are an excellent source of selenium and will help with the conversion, and I plan to munch one a day.Also,don't I need to include iodine in my diet as well? I have an appointment with a new doctor on Monday morning so what are the most important things to ask??When I asked the clinic doc for a copy of my labs he looked at me strangely too and said "PARDON?"So...........I asked again in a louder voice.

Guest guest Posted March 17, 2006 Report Share Posted March 17, 2006 To answer your question about conversion, there is no way to know whether you're converting or not, since the Free T3 test was not run at all. This is how you know you are converting. High amts of T4 can suppressed your TSH. Some people's TSH is suppressed by smaller amts of T4. As a matter of fact, the TSH can vary by as much as 4 points in one day, so TSH is rather a moot point for so many of us, except for a healthy thyroid system, with no problems at all. Hypo people are a different matter altogether. You won't know til that FREE T3 test is run, and then you won't know whether your cellular receptors for it are working, except by the way you FEEL, and that is if all problems are thyroid related. my labs > I went to the walk-in clinic instead of calling for the results of > my labs, and the doctor decided he wanted to see me.I asked the > receptionist for a copy of my labs and she kinda looked at me funny > and told me I would have to ask the doctor for that.(Strange isn't > that??I mean they ARE mine)I was on 0.1 mg of eltroxin and he told > me that was too much so he lowered it to 0.088 here > they are: THYROTROPIN (SENSITIVE TSH) <0.05 > REF RANGE 0.35-5.00 > > FREE THYROXINE (FREE T4) 28 > REF RANGE 9-23 > > My question is,if my T4 is too high and my TSH too low its > obviously not converting,right?So instead of just lowering my script > shouldn't he have given me something that included T3?That would be > the reason I'm so tired all the time and I've gained 40LBS in a > year??Also,I picked up some brazil nuts because they are an > excellent source of selenium and will help with the conversion, and > I plan to munch one a day.Also,don't I need to include iodine in my > diet as well? > I have an appointment with a new doctor on Monday morning so what > are the most important things to ask??When I asked the clinic doc > for a copy of my labs he looked at me strangely too and > said " PARDON?

HEHE > According to your labs you are hyper..for someone not on replacement hormones..according to your symptoms you are hypo..so something is obviously not right..with these labs though you would have a hard time convincing a doc to give you more thyroid hormones with out a reason.. You need to have a Free T3 test run.. and a TBG test done..It is a good thing you got copies of your labs but did you ask the doctor why if you were so hyper that you felt so hypo?

Guest guest Posted March 18, 2006 Report Share Posted March 18, 2006 Hi Amber, I am on .100 mcg levoxyl and just started two weeks ago on 10 mcg T3 cytomel — what dose did you start at and how often did you increase? I don’t get labs for 4 more weeks and was wondering if I should call in and ask for dose to be upped or wait the full month more ? I feel the t3 working a bit in that my hands are warm but that’s about it so far... My last labs had my t4 high end range and my t3 just 10 about the 230 to 420 range so I know I need it, just don’t know how much and 10 mcg seems low...

Guest guest Posted March 19, 2006 Report Share Posted March 19, 2006 Here is some info from the Merck manual.. About 20% of the circulating T3 is produced by the thyroid. The remaining 80% is produced by monodeiodination of the outer ring of T4 (5´D-I), mainly in the liver. Monodeiodination of the inner ring of T4 (5-deiodinase [5D-III]) also occurs in hepatic and extrahepatic sites to yield 3,3´,5´-T3 (reverse T3 or rT3). This iodothyronine has minimal metabolic activity but is present in normal human serum and in insignificant amounts in thyroglobulin. About 99% of the circulating rT3 is generated by inner ring deiodination of T4 in peripheral tissues. rT3 levels increase in many instances in which serum T3 levels fall because of decreased activity of outer ring 5´D-I (eg, chronic liver and renal disease, acute and chronic illness, starvation, and carbohydrate-deficient diets). This increase in rT3 occurs primarily because of decreased outer ring (5´D-I) activity, which markedly decreases the clearance of rT3. These states of chronic illness, therefore, result in decreased production of the active hormone, T3, and in increased serum rT3 levels due to decreased rT3 clearance. The decreased production of T3 might be an adaptive response to illness. This is also from the Merck Manual and explains why your Free T4 may not be a true free and the roll of TBG.. Indirect estimation of free T4: These measurements are readily available, are simpler, and compare extremely well with the methods for measuring direct free T4 mentioned above. Index methods require two independent tests, one measuring total serum T4 and the other measuring thyroid hormone-binding ratio or T3 resin uptake. The free T4 index is then calculated using the total T4 and the TBG level, the thyroid hormone-binding ratio, or T3 resin uptake. The index is directly proportional to the free T4 level. Immunoassay methods are standardized against a direct measurement of free T4 by equilibrium dialysis, thus results are reported in absolute units (ng/dL or pmol/L). The two most commonly used methods are a two-step and a one- step immunoassay method using a T4 analog. These assays are not completely free of the influence of binding proteins or substances in serum that may result in false increases or decreases in the free T4 levels. Measurement of total serum T3 and free T3: Since T3 is tightly bound to TBG (although 10 times less than T4) but not to transthyretin, total serum T3 levels measured by the same methods described above for total T4 will be influenced by alterations in the serum TBG level and by drugs that affect binding to TBG. Free T3 levels in the serum are measured by the same direct and indirect methods described above for T4. Diagnosis It is important to differentiate secondary from primary hypothyroidism; while secondary hypothyroidism is uncommon, it often involves other endocrine organs affected by the hypothalamic- pituitary axis. In a woman with known hypothyroidism, the clues to secondary hypothyroidism are a history of amenorrhea rather than menorrhagia and some suggestive differences on physical examination. In secondary hypothyroidism, the skin and hair are dry but not as coarse; skin depigmentation is often noted; macroglossia is not as prominent; breasts are atrophic; the heart is small without accumulation of the serous effusions in the pericardial sac; BP is low; and hypoglycemia is often found because of concomitant adrenal insufficiency or growth hormone deficiency. Laboratory evaluation demonstrates a low level of circulating TSH in secondary hypothyroidism (although serum TSH may be normal by immunoassay but with decreased bioactivity), whereas in primary hypothyroidism there is no feedback inhibition of the intact pituitary, and serum TSH levels are elevated. The serum TSH is the simplest and most sensitive test for the diagnosis of primary hypothyroidism. Serum cholesterol is usually high in primary hypothyroidism but less so in secondary hypothyroidism. Other pituitary hormones and their corresponding target tissue hormones may be low in secondary hypothyroidism. The TRH test (see Laboratory Testing of Thyroid Function, above) may be useful in distinguishing between hypothyroidism secondary to pituitary failure and hypothyroidism caused by hypothalamic failure. In the latter, TSH is released in response to TRH. The determination of total serum T3 levels in hypothyroidism deserves mention. In addition to primary and secondary hypothyroidism, other conditions are characterized by decreased circulating levels of total T3; these include decreased serum TBG, the effects of some drugs (see above), and the euthyroid sick syndrome due to acute and chronic illness, starvation, and low carbohydrate diets (see above for discussion of euthryroid sick syndrome). The diagnostic dilemma is whether the patient has hypothyroidism or the euthyroid sick syndrome. The most sensitive indication of hypothyroidism due to primary thyroid gland failure is a marked elevation of serum TSH. In contrast, patients with the euthyroid sick syndrome have suppressed, normal, or slightly elevated levels of serum TSH depending on the course of the illness. Coexistent hypothyroidism in the patient with an acute or chronic systemic illness is also suggested by a low or low-normal serum reverse T3 level. A more difficult differential diagnosis is central hypothyroidism. Serum cortisol levels may aid diagnosis because they will be elevated in patients with euthyroid sick syndrome and low or low-normal in patients with pituitary-hypothalamic disease. A lot of medical mubble jubble, I know..everything I copied and pasted is from the Merck Manual for physicians.. if your doctor questions any of this tell him to go to section 2, chapter 8 of the merck manual.. What you want.. A free T3 A reverse T3 A TBG A serum cortisol .. and if these blood tests do not show the doctor what is going on then you need to ask the doctor more questions. T3 is responsible for so much, Effects of Thyroid Hormones Thyroid hormones have two major physiologic effects: (1) They increase protein synthesis in virtually every body tissue. (T3 and T4 enter cells, where T3, which is derived from the circulation and from conversion of T4 to T3 within the cell, binds to discrete nuclear receptors and influences the formation of mRNA.) (2) T3 increases O2 consumption by increasing the activity of the Na+, K+- ATPase (Na pump), primarily in tissues responsible for basal O2 consumption (ie, liver, kidney, heart, and skeletal muscle). The increased activity of Na+, K+-ATPase is secondary to increased synthesis of this enzyme; therefore, the increased O2 consumption is also probably related to the nuclear binding of thyroid hormones. However, a direct effect of T3 on the mitochondrion has not been ruled out. T3 is believed to be the active thyroid hormone, although T4 itself may be biologically active.
