A Fast Heart Rate Occurs When Hypothyroid or Hyperthyroid

Everyone seems to understand that someone who is hyperthyroid or overmedicated on thyroid hormone will have a fast heart rate. Thyroid hormone speeds up metabolism, so the heart beats faster. What few understand is that a fast heart rate can also result when someone is severely hypothyroid. If neither the doctor nor patient understands this, then a patient presenting with a fast heart rate, high blood pressure, and anxiety may incorrectly receive a hyperthyroid diagnosis, when they are actually severely hypothyroid. They may be prescribed beta blockers for their blood pressure and benzodiazepines for their anxiety, when what they really need is thyroid hormone. The adrenal glands secrete noradrenaline to compensate for the lack of thyroid hormone, and noradrenaline raises the heart rate. Unfortunately, it’s hard to secrete just a little noradrenaline, so the heart rate becomes elevated, blood pressure rises, and the person feels anxious. TSH may be normal, but low Free T3 and Free T4 levels and a low body temperature confirm the hypothyroid state. My heart rate was 100 bpm (beats per minute) and blood pressure 170/100 when I was only taking ½ grain of desiccated thyroid. Raising my dose brought everything back into the normal range.

If a hypothyroid patient with iron deficiency anemia starts thyroid hormone, they may also have palpitations, nervousness, and feelings of restlessness. It’s not that their dose is too high, but that their iron is too low. Adequate iron is required for thyroid metabolism. Patients given supplemental iron for 4-7 weeks have later been able to restart and tolerate thyroid hormone. More information and references are here: http://tiredthyroid.com/feeling-hyper-when-hypo.html

Heart rate is easily measured, and is a good guideline to use when raising someone’s thyroid dose. Normally, as thyroid levels rise, heart rate rises. In fact, a low heart rate, or bradycardia, is a sign of hypothyroidism. It is only at the extremes of hypothyroidism and hyperthyroidism that heart rate becomes elevated. If you are taking over 2+ grains of desiccated thyroid or a significant amount of T3, and your resting heart rate is consistently over 90 bpm, your thyroid dose may need adjusting. Don’t ignore this sign.

  1. My brain is exploding with questions. This site was created for me, or that’s how it feels. After years of what I now believe was too high a dose of NDT, but seemed fine at the time, I suddenly got extremely breathless with little to no exertion, rapid heartbeat as high as 130bpm at one point (120 bpm much of the time) and horrendous reflux. I am still trying to figure out why. Hashi’s flare? Toxicosis? God alone knows but it stopped almost the minute I drastically cut my NDT down. I have some lingering, and very serious, health issues that may or may not be directly linked to this. This site is the first time I have felt I might, with a bit more help, be able to figure out what happened. Thank you.

  2. I’m on synthroid and my tsh is supposedly in the normal range but I have a fast heart rate, palpitations and heart fluttering. When I didn’t take my morning dosage the other day, these symptoms went away. When I resumes it, they came back. The Dr keeps telling me that it maybe sue to something else rather than it being too much synthroid. I’m very confused and frustrated at this point

    • Your Free T3 and Free T4 are better indicators of whether your dose is too high or low, not TSH. Have you looked at your iron and ferritin levels? When those are low, it can cause an intolerance to thyroid hormone supplementation.

    • Yes, I’ve experimented with synthroid and skipping doses and you are very correct. The symptoms go away the day you do not take it. These doctors are totally and completely ignorant.

      • I have been suffering the same for a few years now. However, when I drop a dose of SYNTHROID my symptoms of fast heartbeat (when asleep) inner tremors and burning skin stop within12 hours, I go back to feeling normal. I have been on less of a dose and get exhausted and breathless within a week or so. I was thinking it was the brand SYNTHROID? Wondering if anyone has found a solution to all of this?

  3. This was my problem. I have heart stents in. So about 2 weeks ago my Dr. Called and said my thyroid level was low and he was going to adjust my medicine . Well being I get my meds from a mail order pharmacy . I asked the nurse to call in a script at my local drug store so I could get started on them. She didn’t think that was necessary. My thyroid level was 0.28. So it has been two weeks and no pills from the mail order pharmacy. I was told the reason was because they had to make sure I wasn’t going to take both prescriptions. REALLY. So the other day I woke up pulse that usually runs 60 because I work out all of the time was 120. My blood pressure was 140/80. And my normal range is always 90/60. Any very irritable . Because I was thinking it was a stint blocked I went to E.R. I have had the trouble previously with my stints . I told them during my admission that I had a very low thyroid issue that was unresolved. Well they did the heart catherization , and sure enough it was fine. I’m thinking now after reading your article the thyroid was the link in all my problems. Today a few minutes ago my heart went from 60 to 115. And I feel like my skin is crawling. So tomorrow I’ll be presenting this article to my Dr. I will update you on the results

  4. I see the cardiologist tomorrow for a recent fast pulse of 150 over several hours.
    BP has also been spiking so PCP put me on an additional med which is long lasting but it is not long lasting and I will show cardio my own charting tomorrow.
    With my latest research, I feel this is not a heart issue but thyroid related while I have switched to Nature-Throid and dosing up. Perhaps I got too low??? Perhaps I am reacting with my cells waking up???? Still keeping the cardio appt. to rule out any heart prob and to plead with him to refer me to a better endo. (in my HMO…if that is possible)….than the one I have seen 3 X since last Oct. We are now battling over my TSH results. Newest were low and she immediately said she had to lower my meds. I gently told her she did not have a clue as to what she was talking about and had tild me she would prescribe NDT on this visit. Well, I walked out of there with a scrip of 97.5mg. Nature-Throid with 5 refills!!! But I have to cut them into the smaller doses because she told me to take the whole danged pill. Did that and got very sick. BTW, my history with Grave’s Disease goes way back and I bet longer than anyone else on this site! Any comments and help greatly appreciated!!! We are in this battle together and I am glad to have run into this site today while researching.

  5. I also had Graves disease and had RAI in ’06 Im too low now and having fast heart rate and occasional palps…..on synthroid only I gained 30 lbs and had to have naps most days….found a Wellness clinic where they have tried to regulate me…been up and down….Now I have been dx with sleep apnea (awoke last night for first time gasping for air and heart racing and am actually underweight!….. and on the verge of making a cardio appt due to fast heart rate…my PCP gave me prescription for low dose beta blocker :(……..I now take T4 50mcg (beginning slowly on 16.25 mcg of ND and 5mcg of Cytomel T3) waiting on blood work for iron and cortisol because every time they raise it gives me racing heart and intolerable anxiety…..Hard to explain to someone that you know you’re hypo when your heart is racing! Seems like my problem is very common? Thanks Barb for this site!!!

  6. I have hypothyroidism and right now my heart rate is at 96bpm I have been taking a betta blocker for a little over a month now as well as Xanax for anxiety and they started me on ibuprofen(400mg)about two days ago(12-15)is this normal?

  7. Hi, I’d like to get your opinion. After a long, long time of trying to increase my Armour to the correct dose I’m finally in the ballpark. When I was very hypo my heart started to race a few times a day – my adrenals releasing noradrenaline to help me out. I started taking beta blockers and Lorazapam to slow down my heart and help with the anxiety. I could only raise my Armour dose a few mgs. at a time because the Armour aggravated my racing heart and anxiety and I felt even worse. (iron and ferritin levels are good)

    My TSH, T3 and T4 just recently got in range but my heart still races (maybe a bit less than it used to) and I’m still anxious. Please, has anyone been in a similar situation? How long did it take for your heart to calm down and get back to normal? I’ve waited so long to get to this point and nothing seems to be improving.

    (Barb, I clicked on the tabs at the top of the page and got “Internal Server Error” on each page.)

    • I personally can’t take 100% NDT, because it has too much T3 for me. I take a combo of NDT and levothyroxine to replicate a normal thyroid gland. You don’t mention your dose, but is it possible you’re just taking too much T3 at once or in a day? On average, a normal thyroid gland only secretes about 10 mcg T3 daily. Once you pass 1 grain, you’re starting to rise above that amount. Your T4 could also be low on 100% NDT, and that could also contribute to heart issues; it does for me, anyway.

      Thanks for letting me know about the “internal server error.” I tried the links and they worked for me, though I know there are always occasional glitches.

      • Just a clarification for Barb who posted 2/23/17 – Though the thyroid gland itself secrets about 10 mcg. of T3 per day, the tissues of the body produce another 20 mcg. on average. The latter is done by the conversion of T4 to T3 in the tissues. Approximately 30 mcg. is the average amount a healthy person would produce. For those who are hypothyroid and low in T3, that 30 mcg. is not enough to satisfy daily requirements and also to restore T3 into their cells. Thyroxine/T4 is the precursor to T3, an inactive storage hormone. It does nothing without being first converted into T3. It is T3 that regulates the heart, the metabolism, body temperature, etc. If your heart palpitates or beats irregularly, either you need more or less thyroid hormone — and if the latter is not easily corrected, chances are you are taking a medication that is interfering with the absorption of thyroid hormone (beta-blocker or statin which removes cholesterol and cholesterol is needed for the production of thyroid hormones {and other hormones}). Hope this is of some help to you and others.

        • Hi Charmaine, Thanks so much for the very helpful information. I have some new labs now after taking 1/2 of 0.025 Synthroid in the evening as well as 2 x 30 mg dessicated thyroid on rising and 1 x 30mg dessicated in late afternoon. I suspect that the tiny bit of Synthroid is helping my temperature…I was really feeling the cold.

          Thyroid Stimulating Hormone [TSH] 0.95 (0.32-4.00)
          Thyroxine Free [Free T4] 10 (9-19) pmol/L
          Triiodothyronine Free [Free T3] 4.8 (3.1-6.2) pmol/L
          Testing done 4 hours after taking morning 60 mg ERFA

          TSH up slightly 0.90 – 0.95 and Free T3 up .3 but FreeT4 unchanged.

          I am surprised that adding the synthroid did not make a bigger difference. My doc suggests I add 1/2 x 30 with the afternoon dose. Will try it and see.

          Doc also told me to move Synthroid from evening to morning. I hate waiting for a half hour for my coffee but have found the evening time difficult. I also just realized that one should take Synthroid 4 hours away from minerals like magnesium which I take at bedtime to help with sleep.

          Do I really have to wait for a 1/2 hr for my coffee?

          Thanks, Oci

        • Hey Oci,

          Forgot about the Synthroid question –

          Take the magnesium during the day and then four hours before bedtime. Some need more magnesium than others. You will find the amount that works for you. It was experimentation with magnesium that I found taking two doses per day works best for me. I no longer take it at bedtime and am finally getting some restful sleep.

          Then you can take the Synthroid when you go to bed and have your coffee as soon as you get up!

          Remember, the T4 (Thyroxine) in Synthroid is no different than the T4 (Thyroxine) in the Erfa you take. Treat them both the same — away from caffeine and minerals.

          Healing Hugs!


        • Charmaine, I love you answers but have difficulty finding my way around the posts!

          Just to clarify. You said…
          “FYI: The Erfa you take is measured by “grain.” One 60 mg. tablet equates to one grain. One grain is 38 mcg. T4 and 9 mcg. T3. Since you take three grains of Erfa per day, you’re getting a total of 114 mcg. T4 along with 27 mcg. T3. That’s plenty enough T3 to shut
          down the signal for TSH. A healthy body produces on average about 30 mcg. T3 per day. You’re getting that. But it is quite possible you will need more to make up for the lack of T3 in your cells”

          I am taking 2 x 30 mg Erfa in the morning and then 1 Erfa in afternoon which I believe makes a total of 1 1/2 grains per day, not the 3 grains you were calculating.

          Drats! I don’t like to wait for my coffee. Since I do I might as well take both Erfa and Synthroid first thing in the morning. Magnesium and other supps @noon and magnesium again at bedtime. Yes, it does help with sleep.

        • I disagree with some of your statements. T4 is not merely a storage hormone, but has properties of its own, as T4. There are T4 receptors in the body: http://www.tiredthyroid.com/blog/2015/03/11/who-said-t4-isnt-important/

          Thyroid hormones are not made from cholesterol at all. They are made from iodine and tyrosine. Cholesterol is, however, necessary for the production of other important hormones likes cortisol, aldosterone, testosterone, estradiol, and others.

        • Thanks for your reply, Barb.

          Sometimes I don’t proof my work. Sorry about that. It should have read simply “hormones,” and not “thyroid hormones.” Thank you for catching that. Cholesterol is necessary for hormone production but not thyroid hormone production.

          As far as T4 being the precursor to T3, that is true and said in context with the importance of T3 being replaced in the cells and having to be converted from T4 as its storage hormone. It was not meant as a general statement about what all T4 does in the body.

          Very nice to hear from you. I’ll try to be clearer in the future.

          Thanks much!


  8. I feel like my doc wants to off me, or at least I saved him from a big fat malpractice suit.
    I was at my PCP for another, pretty scary issue, he ran the CBC, and I received (via e-mail. Thanks, that literally kept me up all night, freaked out and almost wishing I …. didn’t need to live anymore. Not suicidal, just beyond tired of having every illness on the planet and here comes another)
    Any way, my heart for the past maybe four years has been scary fast. Short version, my doc’s email said “Your TSH is high, please pick up synthyroid stat, you will take that for the rest of your life”.
    Crap. So I read about it, how it raises heart rate, my father even accidentally researched HYPERthyroidism because it seemed more logical to him with my scary pulse (His sweet wonderful father died in the middle of the road while on a walk with my Gran, heart aneurysm. Then six years ago, my Dad had a massive heart attack.

    I don’t know what to do. I don’t even think hypothyroidism was a proper DX for me, I just don’t have the symptoms (well, very slowed down metabolism, but I have been sad and haven’t been exercising, did eat my feelings for a good while)

    What would any of you do? My PCP scared and intimidates me and the lady who drew my blood was completely distracted, she was EATING when she took my blood and said something hateful which was so shocking. So this all feels surreal, I feel lost, and my parents can’t shoulder this burden with or for me. I already have Fibromyalgia and migraine disorder, I have to eat the second after I wake so I can take meds for migraine and allergies, some of my meds are contraindicated with synthyroid… (Why is that the only med on the market, btw? )

    I’m so sorry to go on and on, I’m just spun. My beautiful mom is suffering with dementia symptoms, and she counts on my excellent memory. Which is supposed to suck with hypothyroidism, right? And still panicked about my heart just….
    I’m sorry. Just so scared.

  9. Hi Barb,

    Wondering from your experience or knowledge what this can mean. Almost 3 years out and still dealing with this hell. Was recently on 163 levo and two labs in just over a week had conflicting reviews: one TSH was hyper, the other hypo and the FT4 was low-ish while the other mid-range. I’ve wondered if I’ve been overmedicated as my brain just feel “heavy” and even though a new doc wanted me to raise, I asked about dropping to 137. New in and I’m getting now where it feels like my body is absorbing this medicine faster and when I am sleeping, it’s like clockwork where I am jolted awake early in the morning with a racing heart and what feels like anxiety in my chest and sweating. This stops bout an hour after taking my medicine now. But the heart is racing! I’ve had a migraine almost daily since the reduction and even though I feel better mentally, not sure about physically. Any thoughts?

    • 163 levo is a pretty high dose of T4. At that point, you should also be supplementing some T3 for balance. I know when my dose is too low I tend to wake in the middle of the night with similar symptoms. Have you ever tested your FT3? That can help you decide, in conjunction with FT4, whether to add or reduce T4 or T3.

  10. Hello everyone…my name is Sheena! Just coming to this page for a little support. So I had a doctor’s apt a week or so ago and of course had lab work done. My doctor calls a few days ago and tells me that my TSH level was high but my T3 and T4 was normal and that means that I have hypothyroidism and that she is calling me in a script for 150mcg of levothyroxine. I’m really terrified to take it because I read that it can cause fast heart rate because I already suffer from tachycardia and have to take beta blockers…i also have high blood pressure and type 2 diabetes. I can’t stand the thought of something else making my heart race. Can anyone help..im scared!

  11. Hi Barb, I was delighted to find your website and your book. I read the intro and find it very helpful. Will work on rest!

    I’m also encouraged to find that you take a combo of Levothyroxine and NDT. My doctor would like to bump up my thyroid function by adding 1/2 of a 0.025 of Synthroid. I have been hesitant to do so as my heart rate of late is very high for me – often high 90s or above. Also BP has been running high. Normally both are much lower.

    Last lab results were done in January! I have Req for new labs as soon as I’ve added Synthroid for 6 weeks.

    Thyroid Stimulating Hormone [TSH] 0.9 (0.32-4.00)
    Thyroxine Free [Free T4] 10 (9-19) pmol/L
    Triiodothyronine Free [Free T3] 4.5 (3.1-6.2) pmol/L
    Testing done 4 hours after taking morning 60 mg ERFA

    I’ve been taking 60 mg of ERFA in the morning and 45 mg ERFA late afternoon. I don’t pay much attention to having an empty stomach!

    I’m really thinking I need to lower the ERFA before adding the Synthroid. I guess I am hesitant as I’m afraid I’ll gain weight with a lower dose!

  12. Hi i have mu heart racing every day. My tsh levels are normal but my t3 levels are high. My doc says it is because i take birthcontrol. Is this true? Can a high t3 lead to heart palps?

  13. HI I have Hashimotos and awful racing heart beat and palpitations at night. But apart from that I have a small lesion on my pituitary gland and was wondering if that has an effect on my thyroid?

    • yes, the lesion on your pituitary will affect the function of your endocrine system. It can over or under stimulate response from the adrenals causing an excess or lack of chemicals that contribute racing heart, palps, sweating, etc.

      this disease and side effects really stink. hang in there, read up on triggers for the Hashi’s. in some cases tsh suppression works best.

  14. I am taking T4 only and my t3 is in mid range T4 is over range. I am having severe daily anxiety attacks. My doc told me to stay on this dose 175 Synthroid and put me in anxiety medication. I am dying here. I cannot function. A walking zombie now since beginning this medication for anxiety. My child is worried about me and shouldn’t be. I have no money for independent labs. I don’t think I’ll be here much longer. I’ve been to ER so many times for this anxiety. They run my labs and tell me my levels are good with slight over range T4. I just cannot deal with this anymore pulse is over 100 daily. This is a nightmare. Im always normal. Are these docs trying to kill me?

    • If your T4 is over range, then it would make sense to trial you on a lower dose to see if it helps your anxiety before giving you anxiety medication. Please let your doctors know that your pulse is over 100 daily. That is a sign of overmedication and is another sign your dose is too high.

  15. Graves Disease in 1989 RAI…on Synthroid since then. Synthroid has had some major changes in their formula since that time. Initially it was OK..then as the years ensued, it became intolerable for me. Rapid heart rate, hi BP, and diahrea almost every day. Had adjusted dose up and down no go, I am beside myself. I have started dropping a dose once a week to relieve the symptoms which they do. But then I become hypo. My bloods are in the high ranges right now, but I present hyper thyroid. All test have shown I have no thyroid tissue function now. My normal TSH is usally 5 point something, or at least that is when I feel somewhat normal. So much to say, and it is such a long story. Synthoid overdoses through the years (especially when they changed the formula) put me into A Fib. Something to keep in mind, it is directly responsible by the physicians they say. As of this last year, when I cut the dose for two days (no medicine) tremors stop and the A Fib slows down, and sinus tach stops (early AM sleep) and within a week I can hardly function at all. Beside myself. Are there any other formulas or brands that do not have these side effects? Love this site, it is current and the knowledge is invaluable. Thank you for helping. Very depressed as i have tried everything. So am i reading here that you can be hypo and have hyper symptoms as well? What is the answer then? I cannot go off as I will not live without thyroid. Is there a brand that is more stable. I get the feeling with Synthroid (analogy) that one pill could be stronger than the next and it is not the dose they say? Help!!!

    • Zoe, please find an integrative doctor to help you. When someone can’t tolerate Synthroid, they may have other deficiencies that need correcting. Have you measured your FT3, iron/ferritin, and cortisol? Patients with low cortisol report vibrating or internal tremors; unfortunately, someone with low cortisol simply cannot tolerate any type of thyroid hormone. You may need to add some T3 to your dose in the form of desiccated thyroid or synthetic T3, but chances are, you won’t tolerate it with very low cortisol. Again, you need a better doctor who will measure and address these issues. Best of luck on your health journey.

      • Hi Barb, thank you so much for your suggestions. I am beside myself for a long time, been to multiple endos and they don’t have a clue. I have no strength, now inner tremors, diahhrea, exhaustion, wake up every three hours with tach and it takes me awhile in the middle of the night to get back to sleep. I actually shake. My thyroid numbers reflect normal, but my clinical symptoms are what I wrote above. I have an appointment tomorrow with a Doctor I believe to be alternative, I hope so. My cortisol I tested myself last month with Saliva and ZRT Labs, it came back very low they said. I hope they can help me to take thyroid again as I can hardly function anymore. I am a designer with the studios and had to retire early as I could not make it anymore. Life is not good and I try or keep trying to get regulated in some way, it has gotten worse through the years. RAI is bad for anyone, I wish they had given me alternative options, however at the time they said NOW or you will go into thyroid storm. To bad…
        Again, thanks again….

  16. Hi my daughter has just been put on meds for hyperthyroidism I didn’t even think about it as my thyroid test was done but I’m currently under cardio for a fast heart rate one of her obvious trates do I need to tell them this? I didn’t think about it earlier as was only told today but is it relevant considering my thyroid test came back ok, I just don’t want her on beta blockers if unnecessary

  17. This is exactly what seems to have happened to me. I was taking NTD for 6 years without a lot of thought over time and felt great. Never better. Then a few things in the family happened and an endo told me to stop it. I was fine for a few weeks but I became increasingly tired and anxious. I was losing a lot of hair and I felt nauseous all the time. Food was going straight through me and I had to force myself to keep eating to keep my weight up. My heart would beat loud and fast often mid-90s. I would wake up at 2 or 3am because of my heart racing. My basal temp would be 37C. So I thought I couldn’t be hypo. I was taking plenty of adrenal support but I still felt weak and shaky. But then I started taking my mid afternoon temp and it was 36.1 straight after a hot lunch and rugged up in coats. So I went to the doc to get my thyroid tested. However she gave me a request for fasting bloods and I could never feel well enough to go that long without eating to get to the path lab for the tests. So desperate and just wanting my life back I started back on NTD building it up slowly. With each of the tiny early doses I could feel it calming me inside. As I raised I was conscious of adrenal stress but kept creeping it up. A few days after my last dose raise my pulse dropped down to more like 80 even when active and 60-70 resting and I’m sleeping peacefully through the night. My daytime energy has returned and I’m feeling like my old self (touch wood). Now I just gave this pickle of no labs and will have to deal with this somehow…

  18. I’ve been on Armour Thyroid 120mg once a day for almost 1 year. I have
    lost all of my hair due to auto immune disorder. I also have Hasimoto disease.
    I recently was hospitalized with chest pain. All tests; chest x-ray, echo, and
    Nuclear stress test came back normal. Now I’m experiencing a rapid heat beat.
    Could this be all related to my thyroid disorder?

    • It could. Hair loss can be from over or undermedication. A rapid heart rate can also be from over or undermedication, but given that you’re taking 2 grains, I’d lean towards overmedication. You should check your FT3 and FT4 about 8-12 hours after your last dose.

  19. I am on 50 mgs of Synthyroid and 5 of Cytomel….Usually my heart rate is in high 50s and Bp around 116/70s…sometimes they just jump up high like 132 heat rate and 150/100 BP all of a sudden…I take 25 mgs of a Xanax immediately and they come back down….heart pounds all the time…not sure what to do….my Mom had thyroid issues and died from her heart going out of rhythm…kinda scares me..my endo only wants to c me once a year….good endos are few and far between where I live

    • The thyroid is the regulator of the heart. If your thyroid is dysfunctional (hypothyroidism), it stands to reason the heart rate will be irregular in many ways. It will palpitate, beat with thuds, or switch to rapid heart beats that can take one’s breath away. It is no leap to realize any of these occurrences can have an effect on blood pressure. It is well known for those who understand what hypothyroidism does. It slows the body down. As the body slows, the blood pressure can be either low or high.

      Stabilized, healthy normal blood pressure, doesn’t occur in the hypo individual until hypothyroidism is quelled (usually with thyroid hormone replacement and the optimization of nutritional levels). Then all symptoms stop. Blood pressure is great, cholesterol levels are stellar, the gallbladder works fine, breathing is wonderful, hair, nails, and skin fantastic (no eczema or psoriasis), etc. etc. Because nutrients lend themselves to thyroid function. This is why so many think all their issues are simply thyroid related and not nutrient related. The truth is that they go together as hand and glove. You cannot attain good thyroid health without having adequate nutrient levels. Yet conventional doctors ignore this time and again, to the demise of the health of their patients.

      For thyroid hormone to ever get to the cellular level, Thyroxine (T4) {either via Levothyroxine or in Natural Desiccated Thyroid (NDT)} has to be converted into Triiodothyronine (T3). This conversion is dependent upon specific nutrients being in place to facilitate it. Without adequate levels of T3 in the cells, the body begins to dysfunction in many different ways.

      For most with hypothyroidism, there is an issue of low nutrient levels and they have no idea as the doctor continues to raise their thyroid hormone to no avail. Conventional medicine doesn’t recognize the need for nutrients to be optimized. And when they do check nutrient levels, their protocol use of “within range” nutrient levels is wholly inadequate for attaining optimal thyroid health. This is why so many hypothyroid sufferers are on unnecessary pharmaceuticals when adequate nutrient supplementation and thyroid hormones are needed instead.

      Functional medicine’s charts will help you in the quest to learn optimal nutrient levels to ensure good thyroid function via peripheral conversions.

      Low Ferritin levels can wreak havoc on the body as full thyroid function is not optimal without adequate ferritin levels and iron. Low ferritin goes hand in hand with low Vitamin D. Low selenium also keeps thyroid hormone T4 (Thyroxine) from converting into the active thyroid hormone T3 (Triiodothyronine). It is T3 that is needed in ample quantities in the cells of the body to keep us functioning in a healthful state.

      There are many nutritional issues that most who are hypothyroid have, due to the lessening of stomach acid as the body slows down. Stomach acid is essential to absorption of nutrients. Supplementation is often necessary in the way of HCL with Pepsin (also known as Betaine). HCL allowed me to reverse the horrors of a lifetime of Inflammatory Bowel Disease (IBD) and Crohn’s. I no longer have issues with them. It’s unreal. Restoring nutrient levels to optimal and ample thyroid hormone (NDT and T3) were my ticket out of that mess. It allowed me to gain T3 while restoring nutrient levels to later facilitate conversion of T4 to T3.

      If you are simply taking T4 as your thyroid hormone, it is highly possible you’re either not taking enough, or even more likely, that you are not converting the T4 in an optimal fashion so as to provide your body with enough T3 at the cellular level. Blood tests indicate your TSH is low due to the intake of thyroid hormone, doctors mistake that for optimal thyroid hormone or too much. TSH is useless as a measure for dosing needs after it has lowered to 1.5 or below. The Free T3 and Free T4 tests will tell the tale.

      Understanding the nutrient deficiency connection with hypothyroidism has brought me back to health. It was something no doctor ever talked about or even recognized. In fact, I asked for nutrient levels to be tested, and both my GP and Endo refused to do so. I decided to put my life into my own hands and get educated on the matter. With no thyroid, I certainly couldn’t put my life in their hands any longer. They both were more than inept. They follow standard protocol for all. Thus, individuals who don’t fit into that protocol fall through the cracks.

      It took much research and discovery for me to learn how to heal myself when conventional doctors were too inept to do so. Their protocol does not understand the nutrient connection and how it not only can cause hypothyroidism to be acquired, but also how ignoring it keeps hypothyroidism from being corrected.

      Learn all you can about hypothyroidism and the truth will come to you. It does because it will make total sense when all the pieces are put together. It’s the greatest puzzle you’ll ever put together, as your life will flourish because of what you learn. You can then be totally proactive in your healthcare and demand the treatment your body requires. Sometimes, all a conventional doctor needs is a little push in the right direction. If not, challenge him or her on the issue. They will be eager to prove you wrong. But not only will you be right… you’ll be healthier!

      Or you can see a doctor of functional medicine who already gets it.

      Hope this helps!

      Healing Hugs!

  20. I was in a nuclear accident. Tumors on Thyroid from radiation. Thyroidectomy 2 years ago. 90mg Armour. My heart races and I’m cold and very sad. I live in the Midwest.

    • If you have no thyroid gland, 90 mg of Armour would not be considered full physiological replacement. A normal gland secretes, on AVERAGE, 100 mcg T4 and 10 mcg T3 daily. Your dose only has 57 mcg T4, though you have 13.5 mcg T3. Please check your FT3 and FT4 and read my book for more detailed information.

  21. I’m hypothyroid and every morning when I wake up my heart rate is 110 BPM. I’m not on any medication yet so is there anything I can do

  22. I am suffering hyperthyroidism for 19 yrs as soon as I come of my meducation I get very sick.
