Thyroid Hormone Levels: T4, T3, T2, and T1

Your thyroid gland, which is situated in the lower front part of your neck, produces hormones that play a role in a variety of functions throughout the body, and impact many other hormones outside the thyroid. The two main states of dysfunction seen in thyroid conditions are called hyperthyroidism (too much hormone) and hypothyroidism (too little), and can be induced by a number of different individual thyroid disorders. There are many conditions involving this gland, each of which presents a unique pathology and characteristic clinical picture, usually seen when lab values for these hormones fall outside their normal ranges.

What hormones are made by the thyroid gland?

Of the several “thyroid hormones” produced by this gland, there are two that are clinically relevant. One is called thyroxine, also known as T4, while the other is named triiodothyronine, commonly referred to as T3. They are both heavily involved in energy management and a variety of biochemical and metabolic reactions and functions throughout the body. While T4 is more abundant in the bloodstream, it is T3 (which is derived from the conversion of T4 in the kidneys and liver) that possesses the most potency and is thus responsible for most metabolic activity. In the event that a patient requires supplementation because of low hormone levels, both forms are available therapeutically, and an endocrinologist will be able to explain which is needed and why.

What are the optimal levels of the main thyroid hormones?

The normal lab range of total T4 in adults is approximately 5-14 micrograms per deciliter (mcg/dL), while free (not bound to proteins) T4 is considered normal between 0.8–2.0 nanograms per deciliter (ng/dL). Total T3 should be between 80-200 ng/dL, and free T3 should remain within a range of 2.3–4.2 picograms per deciliter (pg/dL). However, optimal levels of any hormone are often debated and may differ from country to country, doctor to doctor, or institutionally.

What is the difference between “free” T3 and T4 and “total” T3 and T4?

Total T4 and T3 indicate the total amounts of these hormones produced by the thyroid gland, whereas free or “unbound” T4 and T3 measure the amounts of hormones that are bioactive, or actually available to your cells and tissues (typically less than 1% compared to the total produced). Looking at the free hormones usually gives a better clinical picture to the doctor, and is generally more helpful for diagnostic and treatment purposes.

What is TSH or thyroid-stimulating hormone?

TSH, also known as thyrotropin, is actually not a thyroid hormone; rather, it’s a pituitary hormone that stimulates the production of thyroid hormones. High levels of TSH may indicate that the body is hypothyroid, though there are other reasons for elevations, such as a primary pituitary tumor. The traditional reference range for TSH has been between 0.5 and 6.0 milli-international units per liter (mIU/L), although many endocrinologists now recommend that it remain between 0.3 and 3.0 mIU/L. However, if the upper portion of the normal range were lowered to just 3.0, approximately 20% of the population would be considered hypothyroid, instead of about 5% now. TSH levels outside the normal range may be associated with a number of disease states.

What are T2, T1 and calcitonin and why doesn’t my doctor measure those?

T2 and T1 are thought to play minor roles in the thyroid and rest of the body, primarily serving as precursors to and byproducts of T4/T3 formation. They may be more involved in thyroid function, but as far as we can tell right now, they have little impact beyond that noted. Calcitonin is a thyroid hormone that, along with parathyroid hormone (PTH), regulates calcium, and it is another measure that can be too low with hypothyroidism.

T2 and T1 aren’t measured because they have no demonstrated clinical value. Calcitonin is sometimes measured as part of an “extended thyroid panel”, when trying to settle on a definitive diagnosis where none is clear, especially in the cases of some suspected endocrine tumors. Values for the latter are considered normal below 10 pg/mL in men and 5 pg/mL in women. Unlike the standard medical treatments for hypothyroidism, desiccated thyroid supplements often contain T1, T2, T3, T4 and calcitonin.

Questions for your doctor:

  • Why do different doctors use different measurements for the “normal” ranges of thyroid hormones?
  • What are the benefits and are there any risks of taking desiccated thyroid products?
  • Is a TSH test diagnostic of hypothyroidism by itself?

    I have been diagnosed with over active thyroid. I was told that my T1 level was high. I generaly feel tired, losing my hair and so on. What is the best action to take? the doctor sugested raioactive iodine and meds for life. I feel lost and like doing nothing about my problem and just letting the thyroid run its course. If I take the doctors advise will I feel better? I don’t my symptoms to go away I want to be cured.

    • Lila says:

      Over active thyroid would involve more abnormal results than an elevated T1. You need to talk to your doc, or get a second opinion. If you can stand it wait a while, as long as your heart isn’t being affected by hyperthyroidism or graves disease. Sometimes, although it can take years of hell, things can settle down. But in the end, most people never feel well again, no matter which route they choose. All the best to you..!

    • Cherie says:

      Get a second opinion. If you’re losing hair and are fatigued then your thyroid is under-active and not oner-active. T 1 is not usually measured. TSH is commonly tested as a gold standard but it’s not as reliable as a stand alone test. TSH will be elevated if your thyroid is under-active. You need a full panel. I hand an internal medicine doc actually ask me if I was hypo or hyper- thyroid when my TSH came back with a high number. There are a vast nber of doctors who have no understanding about that very important gland in our necks.

      • lizz says:

        I had a major overactive thyroid, gained weight, fatigued, hair loss.. most thing associated with underactive thyroid. The second doctor I went to decided to put me on thyroid hormone since I had gained weight I had to be hypo right? WRONG!! The excess hormones I was given almost killed me on several occasions! Find an endocrinologist and find out your options! High numbers means hypo! Low numbers mean hyper! Good luck

        • JonGrant says:

          High numbers mean hypo only for TSH; for the actual thyroid hormones high numbers could possibly mean hyper. You need to specify which number you are talking about.

    • Emma says:

      I have this problem too..

  2. Sam says:

    I just don’t want my symtoms to go away I want to be cured

    • Katie Cleary says:

      Hi Sam, I’m so sorry you are dealing with hyperthyroid. I know it is so frustrating. If you have Graves’ Disease, the doctor’s recommendations are usually standard treatments from what I know of hyperthyroid. It may also be the case that you will be hyperthyroid for a while and then switch to hypothyroid, which is common with Hashimoto’s (which is the condition I live with). From what I know symptoms can be treated, but thyroid disease cannot be cured as of today. But there is research ongoing, and fingers crossed there will one day be a cure. I know you wrote this a while back, but I just wanted to say that I sympathize with what you are going through and hope things are better today.

      • Sarah says:

        Hi Sam, I am very sorry that you are dealing with hyperthyroid. I am dealing with the same thing, it is very frustrating.
        I don’t know what symptoms you are all having, but I have many, I will pray for you, we have a great and Mighty God, He knows all our sufferings, and He cares, but He wants us to trust Him, that what ever comes our way He will give us the grace we need each day to go on, until He calls us to our eternal home.

      • Dawn says:

        Hi Katie
        I was told about a year ago my thyroid levels were off they waited 3 months tested me again and again off they put me on meds but after a few I quite taking them I work nights and nights I had off I was forgetting them ! Well again they took my levels again it was 11 I really scared of side effects of it ! I think the combo of stress not eating right working night and not getting enough sleep I’m confused if I should take it

        • Carmen says:

          Hi Dawn, hopefully you are doing better, I too have hashimoto thyroid problems, I follow a diet free of gluten, sugar, dairy products, no frying, and plenty of sleep, yoga and many natural supplements, I think you could do it also, I wish you the best.

  3. Tricia says:

    There is no such thing as t1and t2. Your reference page mentions nothing bat these “hormones” please stop filling people heads with false information. If I am wrong and you have medical documents to support it please share.

  4. judi says:

    diagnosed with hypothyroidism. each month t3 t4 increased due to dry skin,
    hair and other symptoms, now t3 40mg & t4 105mg, still feel same, what
    should I ask my doctor? Also elevated homocyteine and leptin and inflam-mation. Any suggestions I would greatly appreciate.

    • Katie Cleary says:

      Hi Judi, I’m the founder of this site and I too have hypothyroidism (Hashimoto’s). One of the reasons we wrote this post is that natural thyroid medication, such as Armour and NatureThroid, includes all four thyroid hormones – T4, T3, T2, T1. If our body made enough thyroid hormone, it would be making all four, yet the synthetic hormones only replace T4 and T3. I’m not a doctor so please don’t take this as medical advice, but there are many advocates out there that believe natural hormone replacement will relieve symptoms better than synthetic. I think it varies person to person, but I have had much better luck on Armour than I did on Synthroid (see Stop The Thyroid Madness website for more info on this). I’m not sure about the other part of your question, but I would be happy to post it to the Facebook AutoimmuneMom page if you want and can report back – let me know! Thanks and take good care, Katie

      • Alan Inselberg, C.C.N. says:

        Hi Katie, I am a Certified Clinical Nutritionist who was mentored in the use of Iodine by Dr. David Brownstein, M.D. I specialize in the restoration of the Thyroid and the use of Iodine, which along with the Amino Acid Tyrosine is essential in producing Thyroid Hormone. I have reversed Hashimoto’s Disease in 4 patients. As time permits I offer my professional advice for free to help Mankind and keep them from the clutches of Big Pharma. I teach individuals how to heal themselves so they don’t become anyone’s patient for the rest of their life. I do this solely with a change in a person’s Nutrition profile that includes a lifestyle change in their food choices. I happened across your site quite by accident while researching where to purchase a bio-identical T2 Thyroid Hormone, which is the primary Thyroid Hormone to assist in weight loss. For your reference, a normally functioning Thyroid will produce 80% of T4, which is a storage hormone; 16% of T3, which is the energy Hormone; and 4% of T2 & T1, and less than 1/2% of Calcitonin, the Hormone used to help regulate Calcium. May I suggest that you become greater informed about the significance of Iodine and why you can not live without it from a video lecture by Dr. David Brownstein at this link “!” It was a lecture done at the American Nutrition Association in 2011. I would also suggest Dr. Jorge Flechas, M.D. videos “Iodine & Cancer” and “Iodine, Whole Body Sufficiency” Dr. Jorge Flechas, MD and Dr. Guy Abraham, MD were Dr. Brownstein’s mentors in the use of Iodine. Once you have seen these videos and desire more information I will be delighted to advise you how to get rid of your Hashimoto’s Disease and all of your Hypothroid symptoms for good. And then you can, from your own personal experience, help many hundreds if not thousands of others with the same or similar problems. Your site can grow like my friend Lynne Farrow who found Dr. Brownstein’s information and cured her Stage 3 Breast Cancer using Iodine, and created a site to empower other Women that they too have another choice. Her site is entitled “” Ms. Farrow also wrote a book called “The Iodine Crises” The forward of the book was written by Dr. Brownstein. As a general rule you should never need to supplement any Thyroid Hormone if you still have a Thyroid. Whether you have a Thyroid or not you still need to ingest Iodine because other tissue, such as the Ovarian Follicle also make Thyroid Hormone just like the Thyroid itself.

        • Shawn Cohen says:

          Thank you Alan Inselberg! I can not believe no one has replied to you! I for one will most certainly take up your beautiful and generous offer! I totally agree that Hashimoto’s can be reversed, and “cured” and there are many Functional Medical Practitioners who agree with you. To say a disease can NOT be cured is arrogant and downright wrong! If you clean out the mess which supports the disease, the body knows how to heal itself! Mercury fillings and heavy metal overload in the system which can also create systemic candida (which is protecting the body from the toxins but is also cancer causing!) So in the end, you can see there are many factors. If people do a blog, they should really look into the latest discoveries and insights for the dis-ease they are writing about! Otherwise Big Pharma gets their dues by us all being on their toxic medicine the rest of our lives…or what is left of it and what do you call a “life”!? Thanks, I will be emailing you asap!

I have been on Armour for about a year and see much improvement from the years of synthetic medicine. Thank you for your informative comment. I woould like to get in contact with you for nutritional information that will further help me cure my disease.

          I am very intrigued by this timely find. I have been looking and looking for information on Hashimoto’s and calcitonin. I am a nutritional therapist and I too see there is a better way of healing people and it isn’t just with drugs. Now in saying that, I must declare that I am on t3 only as a medication and feel as if the bag has been pulled off my head. 15 yrs of being treated with Synthroid! I have tried to take iodine, but without knowing the proper way to get it into my body and the dosage I have steered clear, only taking in dulse and nori. If it’s ok, I will email your above address, I would love to hear more about the ovaries producing thyroid hormone!

  5. Marcia Parr says:

    I was diagnosed with polymyalgia in 2000. I was on prednisone for 4 1/2 years. My hair started falling out slowly. now I have lost over half of my hair. It falls out on floor and I can feel it falling on my shoulders. I have been on T3 for over a year. Not any better. I have had blood work a couple of weeks ago , Came back normal. I have requested a printout of results. Do I need to have T1 T2 checked? I am at a loss. Thank you,

    • Katie Cleary says:

      Hi Marcia, thanks so much for your comment – I am sort of at a loss as to how to answer you though. As far as I know, doctors do not track T2 and T1 and as you can read above, part of the reason for the post was to point out that our bodies make all four hormones but we thyroid patients who take synthetic hormone are only getting T3 and T4 (where as natural hormone replacement, such as Armour and NatureThroid, will have all four). When you say your blood work came back normal, were they checking Free T4 and Free T3, or just your TSH? It should have been all three, with an emphasis on FT4 and FT3. I’m sorry you’re going through this and am hoping things get better — and if your doctor is not listening, it might be time to find a new one if you’re losing hair and the doctor is not helping you deal with symptoms. Fingers crossed for you!!

      • Lila says:

        Actually, the majority of Hyp-O patients are only receiving T4 supplements…as in Synthroid or Levothyroxine. The body converts T4 to T3……IF it is able to convert properly. But a doc can give the patient an RX for T3, most don’t though. Holistic docs are better for it.

  6. John Tod says:

    I read what you wrote about T1 and T2, and I want to let you know that what you said is WRONG!
    How dare you tell people that T1 and T2 don’t do anything to speak of.

    T1 and T2 when they are low in patients, causes sever depression.
    Hypothyroid patients that are on T4 therapy, and find themselves depressed, need to change to Armor thyroid, or equivalent, meaning thyroid medication that has T1,2,3,4, and Calcitonin.
    Once a patient that changes to this kind of treatment, their depression magically goes away after some time, it takes a couple of months, because the levels of the T1,2 are so low.

    • Natalie says:

      I don’t think that’s what the site is saying. They are saying that the medical industry does not regard T1 and T2 as important. That’s why our doctors only prescribe T4 and T3. From reading Katie’s comments, I believe the site is advocating natural hormone replacement drugs, like Armour, because they do find T1,T2, and Calcitonin to be important. If they are produced naturally, then they are important to our health and well-being and should not be ignored.

    • Lila says:

      How dare you make such claims as T1 and T2 doing nothing…! Without providing links to credible scientific studies. For one thing there aren’t any studies proving it. Secondly, the body wouldn’t be making these hormones just because it has nothing better to do. So, to make the uneducated, undocumented claim that they have no function and jump on someone the way you did is incredulous. It wasn’t that long ago they didn’t even know T3 and 4 existed and how to measure and still they don’t really know all the details of how they work. Smart doctors are the first to admit it. An old saying…..”Absence of proof is not proof of absence”. Show the study buddy….that’s all I have to say in the end.

  7. Natalie says:

    Hello, Katie. I wanted to know how to go about finding a good open-minded, knowledgeable, progressive endocrinologist that would prescribe natural hormones to me. I have seen 5 doctors in the last 2 years and they’re all uncomfortable prescribing Armour or Naturethroid. I live in California (Los Angeles) so you think it would be easy, but it hasn’t been. Every doctor wants to give me synthetic Synthroid only. I’m finally on a combo t4/t3, but I really want to try Naturethroid. I have no thyroid and a horrible weight problem. My email: [email protected] if you want to respond this way. I am open to suggestions and will not jump on you for having opinions. I know you are not a doctor and I realize that I am responsible for my own health. I hope to hear from you soon.

  8. Katie Cleary says:

    Hi Natalie, thanks for the kind words and I am so sorry for all you are going through. I have a friend on NatureThroid who swears by it. I was never able to get a traditional endocrinologist to prescribe Armour for me, so I had to go to an integrative medicine practice. I believe naturopaths and functional MDs will also prescribe NatureThroid or Armour. Not living in LA area, I don’t know who to send you to, but there is this website that I found that lists holistic doctors:

    I can also post this question on the AutoimmuneMom facebook wall if you would like to see if others in the LA area could recommend someone. If you want to reply here or go to the facebook page and message me, I would be glad to post there for you. Take care and don’t give up until you get the right doctor – it is worth it to go on natural thyroid hormone replacement in my opinion – so glad you are pursuing this treatment path!

  9. Raima says:

    Hi Katie,
    Thanks for your responses, I appreciate them, I find them very helpful and informative. My endocrinologist told me to repeat my blood test in 3 months and then she decides if selenium that she had prescribed would be enough or I should start thyroid hormone replacement. I will be following your new posts. Best regards

    • LAHs says:

      Hi Raima,
      Selenium is essential for the conversion of T4 to T3, it is a catalyst. However there are other catalysts, Ferritin (from iron), zinc and magnesium. You might want to get those measured as well as your T3 and Selenium. Yours is the problem I have at the moment. I have solved most of my symptoms by switching to Armour thyroid but the T3 in it reaches it’s half life 4 hours after you take it (I take mine about 7am). My goal is to convert the residual T4 to T3 in the afternoon. I have been eating Brazil nuts (crazy high in Se) in the afternoon and it has helped a bit – but I suspect I need the other three catalysts. Like you, I have a blood test coming up when I hope to find out.

  10. pamela says:

    hi my dr just told me that my t3 level is good but my t4 level is elevated so she wants to lower my syntyhroid . This upset me me & I am questioning her knowledge on throid because I am having serious issues of hypothyroidism yet she wants to lower my medication . It doesn’t make sense to me please help me out here

    • Katie Cleary says:

      Hi Pamela, I am not a doctor so please take this reply with that in mind. I also have Hashimoto’s hypothyroidism and agree that T3 is very important and so I would also question the dosage change. How you feel should also be taken into account – if you are still tired and having other hypo symptoms, I would not think a dosage change would be good for you. My best advice is to look for a second opinion, and I have has the best luck with integrative or functional medicine providers. You should be able to search for one on google, only problem is that some of them do not take insurance so make sure you know their insurance policy going in. Good luck and trust your instincts! Take care, Katie

    • LAHs says:

      Hi Katie,
      I have just gone through exactly the same problem. I struggled for 2 1/2 years with hypo symptoms with reasonable T4 and a bit low range (but called normal) T3. My doctor said she wanted to reduce my dosage. I was terrified. I decided to try the new lower dose myself before receiving a three month prescription – I don’t want to scare you but it almost killed me. I e-mailed her regarding my hypo symptoms and she replied telling me I was hyper not hypo! probably because my TSH has never tested anything but zero – which is probably a problem with my pituitary. Anyway, I exploded and ran to the insurance office of my HMO and demanded a sensible, educated doctor – and got one! I am now on Armour with 95% of my symptoms gone – and btw, my symptoms disappeared within half an hour of taking my first pill. Think about that, my 2 1/2 years of sheer misery, fixed within half an hour by an enlightened doctor.
      It sounds like you are going down the same road. Change your doc, sounds like s/he is just like mine. – Oh, and don’t mess around, get on Armour.

  11. Carol says:

    Dear All
    I have just been diagnosed with an underactive thyroid after being ill for 16 years and putting on over 4 stone in weight, despite telling Doctors over 12 years ago that I thought there was something wrong with my thyroid. I have been put on 5 mg a day of thyroxine. It has made me feel better and I have started to lose weight but I have also been very sick at times. I have very little understaning of the disease & my Doctor doesn’t seem to say much about it other than it is to do with the ‘brain function’, I note that the next blood test I have is to measure my ‘T2’ levels but there does not appear to be much info on these levels – most websites appear to mention T3 & T4. Also, my Doctor has not given a partcular name to the thyroid problem that I have – it appears to me that they are advised not to give out too much info!. Does anyone have any idea from the scant info I have given as to what my problem is in particular and is there anyone else out there with the same problem?. I had a throbbing in the back of my head everytime I laid down at night for years & it is such a relief that that feeling had now gone since taking the thyroxine,

    • Katie Cleary says:

      Hi Carol, thanks for your note – did you end up getting tested for T2? That is very uncommon and you are the first I have heard who is to be tested for that hormone. Usually doctors are testing Free T3 and Free T4, sometimes Reverse T3.

      I hope you are not still sick as that is not a typical reaction to going on thyroid medication from my understanding. Perhaps that was just odd timing. It does take a few weeks for your body to adjust to the thyroid hormone coming into your body, so don’t worry if you feel sort of “weird” for a bit – that is normal. Fingers crossed you have gotten some answers since you posted. Take care, Katie

      • Carol says:

        Hi Katie

        Thank you for your reply . Yes, it appears that T2 must be unusual as it is rarely mentioned on these sites – I also believe that it the reason why it took so long to be diagnosed. My sickness has subsided a bit now and I am feeling much better.

        Kind Regards

    • Bek says:

      Hi Carol, I read your post. I have been on 2 blood tests as the 1st one came out as being very high for T1 and T2. Had went to test for the others but I don’t have T3 or T4. I also have a throbbing especially on the back of my head… for years its just gotten so bad now being very tired and stressed to the max. I don’t know what to do. Doctor couldn’t quite explain why or what I have to do or what it actually means. Im wanting to book in a CT scan to have a look if there is something in my brain. Does anyone know what I have to do, do I also need to be on thyroxine? Thank you.

    • Kim Diedrich says:

      Dear Carol, There are books that can help you such as Stop the Thyroid Madness by Janie Bowen and books by Dr. Brownstein, online doctors such as Dr Eric Berg who is just excellent. He has some supplements he sells but is not one to have the infomercial type of program selling like some of the other online doctors. If you go to Amazon or EBay you can find these books very inexpensively. There is alot to know about thyroid. I think the doctors might not say much for this reason. One thing that I didn’t know for long time is that you might be producing the thyroid but for some reason it is being blocked and pooling in your blood. This can happen with other nutrients as well. Hope this helps.

  12. Mohab says:

    My Wife is hyperthyroid, she’s pregnant(First week of the 2nd Trimester) and taking Carbimazole (Like Methimazole) 15 mg/day (three doses), She’s measured the TH Levels, and the Total T4 was in normal range about 10 mcg/dl (normal 6-12), but the Total T3 was high 325ng/dl(normal 80-233), Should she increases the Carbimazole doze or not, and why the T4 level is within normal while the T3 is high????

    • Katie Cleary says:

      Hi Mohab,
      I did a quick google search and it could be that the T3 is high because she is pregnant – see this article: Hope that helps and hope she is feeling all right – know pregnancy throws off thyroid conditions and so it’s good you are keeping a close eye on things. All the best for both of you! Sending good thoughts.


  13. kanakapushanam says:

    what is the optimum level of t4..Why do different doctors use different measurements for the “normal” ranges of thyroid hormones?

    • Katie Cleary says:

      I too am unsure why there are so many different measures. Part of it has to do with the lab which is reporting the blood work and the ranges they use as in-range and out-of-range.

      Another complication is whether the doctor ordered Total T4 or Free T4.

      On my most recent blood work, the ‘normal’ range for Free T4 was .8-1.8 ng/dL.

      Stop the Thyroid Madness and Mary Shoman also have good info on thyroid lab tests.

    Thanks for your info on this issue


  16. Jane says:

    Good morning,

    I was seen by an endocronologist for my lack of energy, weight gain and missed periods. My lab values are as follows: TSH 1.33 T4 1.1

    I have tried everything, exercise, changing my diet seeing other dr’s. I just need some answers. I feel like over the past year my health has been deteriorating.

    I have been hospitalized for pyelonephritis and a lower GI bleed. Dr’s say nothing is definitive enough for a diagnosis.

    I also have low blood pressures and require taking salt tablets three times a day with 2-3L of water intake.

    Does anybody have any experience with these symptoms?

    Any help or guidance would be great!

    Thanks 🙂

      Weight gain, missed periods,high salt needs and water replacement – does your potassium run low? Could be a variant of congenital adrenal hyperplasia- thyroid is a red herring or part of a multiple endocrine syndrome- see a real endocrinologist- also you give no hx in re: heart dz,meds diabetes etc

    My Thyroid blood test in July 2014 & Jan 2015 :

    THYROID Profile :
    Test Jul 16 ‘14 Jan19 ‘15 Normal Range
    Serum T3 2.89 nmol/L – 0.64 nmol/L 1.23 – 3.0
    Serum T4 16.7 ug/dl – 1.30 ug/dl 4.60 – 10.5
    Serum TSH 0.007 ulU/ml – >165.000 ulU/ml 0.50 – 8.90
    Serum Thyroglobulin 69.2 ng/mL – <55 ng/mL

    Symptoms experienced before test & medication : loose stools;
    loss of weight 5kg in a month or so
    swelling and pain in region of thyroid gland,
    high pulse rate.
    Nuclear Thyroid Scan :
    Procedure : Tc-99m pertechnetate thyroid scan done 21-07-2014 [ radio-active Iodine uptake ].
    Description : The anterior spot view of the neck demonstrates markedly diminished radiotracer concentration in the standard anatomical location of thyroid. Background activity is raised.
    Opinion : Low uptake scan [ Drug effect / thyroiditis ? ]

    Diagnosis : Thyroiditis / Hyperthyroidsim
    Medication : Neomercazole [Carbimazole] tablets 10mg x 2 per day

    After taking these for 6 months weight gain is about 6kg & pulse rate has normalised…….still feel tired and lethargic.
    However seeing that the latest readings correspond to a reversal into an Hypo thyroid condition, I've stopped taking the medication to avoid further exacerbate the condition.

    I'm now at a total loss as to how to rectify the present condition possibly produced by the over usage of Carbimazole. I have just come to know that hyperthyroidism has two further sub-types :

    1. DE QUERVAIN'S thyroiditis (also called sub-cute or granulomatous thyroiditis) was first described in 1904 and is much less common than Hashimoto's thyroiditis. The thyroid gland generally swells rapidly and is very painful and tender.
    The gland discharges thyroid hormone into the blood and the patients become hyperthyroid; however, the gland quits taking up iodine (radioactive iodine uptake is very low), and the hyperthyroidism generally resolves over the next several weeks.
    A few patients will become hypothyroid once the inflammation settles down and therefore will need to stay on thyroid hormone replacement indefinitely. Recurrences are uncommon.

    2. SILENT thyroiditis is the third and least common type of thyroiditis. It was not recognized until the 1970s, although it probably existed and was treated as Graves' disease before that.

    This type of thyroiditis resembles in part Hashimoto's thyroiditis and in part De Quervain's thyroiditis. The blood thyroid test is high and the radioactive iodine uptake is low (like De Quervain's thyroiditis), but there is no pain and needle biopsy resembles Hashimoto's thyroiditis. The majority of patients have been young women following pregnancy. [ I'm male ! ].

    The disease usually needs no treatment, and 80% of patients show complete recovery and return of the thyroid gland to normal after 3 months. Symptoms are similar to Graves' disease except milder. The thyroid gland is only slightly enlarged and exophthalmos (development of "bug eyes") does not occur.
    Treatment is usually bed rest with beta blockers to control palpitations (drugs to prevent rapid heart rates). Radioactive iodine, surgery, or antithyroid medication is never needed. A few patients have become permanently hypothyroid and needed to be placed on thyroid hormone.

    Very likely I was actually suffering from one of these. Instead of referring the matter to an Endocrinologist I relied on my GP.
    I would be grateful if anyone can guide as to the best course of action for me………..thanks in advance.

    Just wanted to add to discussion that I recently read that T2 is known to act only on two types of tissues. Hepatic and brown adipose fat tissue. For some reason the medical community thinks due to lower potency of T2, and this limited effectiveness – apparently doesn’t “dock” at other receptors other than these two types of tissues that it is less important. Hmmm….I am a layperson, but maybe this is why there are lots of reports of people on synthroid who gain weight or fail to loose weight. We also know that our fat tissue sends out chemical signals (read, Why We Get Fat, obtainable Amazon) which influence metabolism. So if T2 “talks to” or exerts influence on our fat metabolism (no our fat is not just idle) perhaps it ought not be overlooked. Also, hepatic tissue, our liver excretes glucose. Another possible link to metabolism, blood sugar levels and insulin….

      Thank you Maddy – I just sent in comments before reading your post. I have gained so much weight in the past year, even though I am on Synthyroid and Cytomel. I am very frustrated at age 58 I am very careful with my eating and daily exercise. Like I posted, I had a hysterectomy in 2001 and take bio identical hormone replacement. I have never felt so sluggish and tired as I do now. I am definitely going to inquire further about the T2, very little is written about it and I’m trying to figure out if it’s only a supplement or is it available as a prescription.

    This is an excellent article. I wanted to share a bit about me. I am now 56, and started getting ill in my early 40’s. I was not diagnosed with Hashimoto’s until I was 54. I now take both T4 and T3, feel great most days and am in remission. No symptoms and thyroid antibodies in the single digits. The biggest things that have helped me, besides my doctor and meds, is my own investment in self education and daily vigilance of my health and diet. The thyroid will not operate properly if vitamin and mineral deficiencies are present. I was low in d, iron, zinc and too high in selenium. I corrected those, supplement and monitor my vitamin and mineral levels to keep them in check. Recovery and stability is a lot of work. It can be done.

  21. Hey plz adwise my t3 harmones is higher then normel ….it is 6.51 ng/ml …but normal is 0.8 to 2 …plz advise wat should i do……i have suferring from hypatitus c ….

    Hi Gary – I had a thyroidectomy in 1982, seven months after giving birth. I have been on Synthyroid and Cytomel for several years and have been pleased for the most part; however I have put on weight in the last year (over 20 pounds), and even though I get 8 hours of sleep each night I wake up exhausted. I had my labs done two months ago and my doctor says all of my levels look great. I also had a complete hysterectomy in 2001 and am on bio identical hormone replacement. I work out 3 days a week and watch what I eat. I’m beginning to hear about T2 supplements and wonder why I haven’t heard anything before now.
    Also, will adding a T2 supplement help me to lose weight and have more energy?
    Thank you for your time and consideration in answering my questions.

  24. Chris says:

    Hi, my doctor claims that my recent low energy levels were due to imbalanced T3 levels from stress and skipping meals. I came across this article – on – is there any validity to it? I’m trying to cut down on my hours and improve my diet before medicating.

    Many comments say to change your Dr. Where do you find these Drs? I am near Augusta, Ga. This is the most frustrating part of hypothyroidism. Have been dealing with it for over 40 yrs. Now, for the first time my hair is falling out! Any help out there?

I know there is something wrong with my thyroid my last reading when I had dropped a little weight was THS 3.2 and blood glucose today was 10.0 on waking my symptoms match thyroid and diabetes more than FMS I am putting this weight on for a reason something g has changed I hardly eat granted eat at the wrong times but still you would assumed I ate crisps chocolate and takeaways all day every day. My T4-14.2 and I have pcos also I cannot conceive alone and have no chance now with this weight I will literally have to go on hunger strike for 3 months and I will be a size 10 again I don’t know how to handle this if your border line it’s normal but I feel they are looking at pigger picture me all the time THE said I was wrong you know your own body and I fit in with hypothyroidism I am not just fatigued I can sleep 12-12 constipation, excessive. Thirst that diabetes test was done on diluted 12 litres of water I had lazer corrective surgery for my eyes and my memory is so poor it’s not even funny I can’t function I mess up tablets forget everything what do you think of the scores and history is this in my head like my arthritis was are there room for error in my readings are there things that can alter them….is it worth with buying a private blood test?? I just don’t trust doctors anymore and my weight is unexplainable and I am the only one like this in my immediate family of siblings I can’t take anymore f such a young ages at least in supported the DAUK have sent me a risk assessment for doctor andHT has anyone else seen this someone to trains weigtj so easily and have to go to excessive dangerous lengths to loosenit?


      Please if anyone can help

      My waking blood shar was 10.0 and my thyroid seem borderline.

        Hi Debbie, sorry for your troubles, I have hashimoto’s also, have you ask your doctor to prescribe desiccated thyroid? It was better for me and many others.

  29. Where can you obtain T2 testing?
    I BELIEVE T2 is body metabolism at cellular level.
    I have overactive thyroid although I have no thyroid
    There is no testing of T1and T2 in Australia.
    Can I get this testing in America? Where?

    T1 IS BODY METABLISM AT Cellular level and T1 is growth hormone at cellular level . Both T1 and T2 should be testef
