Another reason to shun T4 meds—your liver

liver6

I’ve been noticing several articles coming out the past week about a strong association between hypothyroidism and a twice the risk of liver disease and liver cancer, especially in females. And then it dawned on me: another strong reason to consider playing basketball with your trashcan using your lousy Synthroid, Levoxyl, Levothroxine or Eltroxin bottles while being replaced with desiccated thyroid at the same time.

In other words, continued hypothyroidism (which being on T4-only meds has seemed to do to patients who report continued symptoms) and undiagnosed hypothyroidism (because of the inadequacy of the TSH lab test) can ‘potentially’ promote the development of nonalcoholic steatohepatitis, a more severe Fatty Liver disease, if these articles are right. The next progression is liver cancer, aka hepatocellular carcinoma (HCC).

Even worse, the study revealed that women who had been hypothyroid for more than 10 years had a threefold higher risk of liver cancer compared to women without a history of thyroid disorders. This will make you pause when you consider how many reports there are of patients having hypothyroid symptoms for YEARS with a normal TSH…and a clueless, TSH-worshipping doctor.

And if reading this bores you, understand that your liver is a HIGHLY important gland that you can’t live without. It plays a key role in detoxifying the toxins you ingest and breath in daily (including smoking), besides being a major fat burner.  Make the liver diseased, and you become a breeding ground for toxins, the rise of other diseases…then death.

The solution? Consider running from TSH and T4-only doctors, find one to put you on desiccated thyroid like Naturethroid et. al (which patients report seems to do a better job getting rid of their hypothyroid symptoms), and avoid the most common mistakes of dosing while ceasing to smoke, curtailing the alcohol, and eating healthy (except for the daily dose of chocolate I gotta have. haha).

P.S. The original report came out in the May journal issue of Hepatology (published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases).  Similar results were also reported in the Journal of Gastroenterology and Hepatology 2005.

    Were the people with Liver Cancer in the study on T4 only medication or did they have high TSH levels?

    Unless you can say that for sure, don’t assume that the addition of natural thyroid medication would reduce the elevated risk of liver cancer within this cohort.

    I am on your side, I just prefer that you not make unnecessary assumptions or imply a correlation where one doesn’t exist.

    Was I the one that you think disagress with you? I don’t disagree with you that dessicated thyroid is better. It is, by far. But this point on Liver Cancer would be stronger if we knew for sure that people in this study were on T4 medicaton. I don’t have access to the journal and can’t say for sure.

    I have always been on Armour and suggest it for any hypo patient, but when there is a chance to be specific on studies such as these, I prefer clarity if possible.

    Hi Mary. The article really has nothing to do with being on T4. It has to do with being “hypothyroid”.

    And I feel pretty safe saying that being on T4 leaves most with continuing hypothyroidism, and I also feel safe saying that being on desiccated thyroid (and in the presence of strong or well-treated adrenals) results in the removal of hypothyroidism symptoms.

    And as a result of the above paragraph, I can make a good “assumption” that the study mentioned only underscores how important it may be to our livers not to stay hypothyroid as being on T4 does, just as it has already shown to be important to our hearts, another major organ. 🙂

    Hope that helps.

    I suppose taking the time to put 2 and 2 together and checking out helpful information would be very beneficial for many hypothyroid sufferers.

    There is proven information and fact that being left hypothyroid can cause liver issues. Weak livers can become damaged / inflammed and sick. If T4 thyroid meds keeps a patient under preforming optimally in thyroid health – the liver can be comsumed into poor quality and function.

    Throw in a shooty conversion table on T4 meds depending soley on using liver function to convert into T3 – and there it is.. a pooped out poisoned liver overloaded to no end….

    Can you please tell me the exact title of the journal article in Hepatology? I’m looking at their website (May issue) and cannot find what you’re talking about. Thanks for all of your help, Janie. I really don’t know what I would have done without you and your website for guidance. I am currently treating myself (don’t ask!) with Armour/Isocort and have never felt better. I understand your parting of the ways with Armour, but please keep closely in touch with us on your blog about how you’re doing on your new meds. Love ya.
    Laura (from Janie: I’ll look and if I can find it, I’ll post it here. And yes, I’ll let you know how I’m doing on Naturethroid. Update: strangely, when I use the search engine, it won’t work)

    I am so grateful for this site. Being born without a thyroid and trying to find a doc that will get me off Synthroid has been a struggle. I have been on it for 30 years. I was just diagnoses with a fatty liver on Monday and I am scared. I also have Celiac. 🙁

    (From Janie: it’ll all work out. Celiac is well treated by going gluten-free, and there is a LOT out there now without gluten. 🙂 Fatty liver will also improve once you are on desiccated thyroid and raising high enough to remove symptoms.

    Well, since finding your website and reading your book, I searched for and found a doctor who prescribed natural thyroid extract. But within days of starting it, my liver started to ache. I thought perhaps it was because it was getting used to this new drug. As my grains went up, my liver pain did as well. I know its the natural thyroid extract, because I recently went on a two week holiday and unfortunately forgot my medication. Had no choice but to go without. And guess what? My liver pain stopped. So I have no doubt its from the extract. Will have to go back to my doctor when I can to find out why this is happening.

    (From Janie: natural thyroid does not directly cause the liver aches. Having other problems, that the natural thyroid reveals, could. Read http://www.stopthethyroidmadness.com/adrenal-info and http://www.stopthethyroidmadness.com/ferritin Become informed so you can teach your doctor!)

    Is there a big difference between armour and naturethroid? I’m switching my 10 year old daughter off of synthroid and I’m on armour.

    I wanted to share a situation. My mom is now 70 and was diagnosed with fatty liver disease in 2002 and now cirrosis (sp)? She was on synthroid for many of those years in misery until switching to Armour last August. Her ammonia level is sky high as well and the doctors are totally baffled because they have no explanation for the liver issues. Could she be one of the stats referenced?

    I have been on thyroid medication since I was 18 years old ranging from .25 to.200 mcg daily of synthroid or levythyroxine. I turn 46 in October and was just diagnosed with liver cancer last week. I don’t drink or smoke and do not have hepatitis.. I’m seriously freaked out and pissed off that this “medicine” every Dr demanded I continue taking has potentially poisoned me!
    Where do I even go from here?

      Jackie, I don’t blame you for being pissed. I just know if it was me, I’d get off Synthroid and move over to Natural Desiccated Thyroid. But you’ll want to make sure you have good cortisol and iron. The liver needs T3. I’d also look into each and every thing I could find to treat liver cancer along with the allopathic methods. For example, this doctor states that low iodine levels could contribute to liver cancer: http://drsircus.com/medicine/iodine/iodine-rescue There’s a lot to read out there.

      you need to report this to the FDA . Make some noise! there are others with liver problems listed in pubmed who can’t take synthroid due to elevated liver enzymes. feel badley for you so sorry

    just found out i have elevated ALT levels so now scared that i may have liver issues now as well as thyroid and adrenal. if i do have it i hope that something can be done about it. i take levo/t3/hc cream/loads of vitamins, i literally dont know what im doing wrong. they have detected low phosphate too.

    I have had thyroid cancer and thyroid removed and have been told I have to take high doses of synthroid to keep cancer suppressed. They said other meds. Would not be effective

    My ND wants me to be tested for heavy metals. He believes this could be a culprit in my thyroid issues and why my body doesn’t convert t4 to t3. The method of removing the toxic metals is done through chelation through an iv. I also heard this can be hard on the liver, although the ND says he doesn’t know anything about that but it can be hard on the liver to have high levels of toxic metals. Does anyone know anything about this? I think I should have a liver function test.

    I was diagnosed hypothyroid at age 13, with anaemia, coeliac and diabetes. For 5 years I took Armour meds from Dr Walzack near LA. Then an endocrinologist in Boston put me on levothryroxine. I have taken 300mcgrams for 41 years, and I’m now 54. I have just had my first liver function test which showed dysfunction of some sort. Your website has me thinking I will ask to switch back to Armour meds.

    I was wondering that I have fatty liver after being on Synthroid only for 23 years . By adding T3 and not going on NDT help as well ?

  17. Hadassah

    Janie , is that with T3 adding to T4 (Synthroid)?

    Reply
    • Janie Bowthorpe

      If that’s what you need to do, yes. NDT seems to be even better, but adding T3 to T4 is a good second choice. Anything over being on T4 alone.

    Janie , I am so very tempted to try NDT . Only because the way I feel . I was wondering three things . Being that I have sensitive stomach the preferred NDT would be Naturethroid or NP Thyroid ? With the least fillers . Also do you still need to add T3 (CYTOMEL) to the NDT ? And do you get the same benefits with swallowing as with sublingually ?

    Reply
    • Janie Bowthorpe

      There’s really no preferred NDT. Some like Naturethroid; some like NP Thyroid; some like WP Thyroid. The latter two have the least fillers, too. A sensitive stomach can actually be the result of having low stomach acid, and NDT improves that. No, people do not add T3 to NDT. NDT is 20% T3 anyway. The only reason people add T3 to NDT is if they have either low cortisol and/or low iron. Yes about swallowing, though some report good results with sublingual.

    Janie , I’m on 88mcg of Synthroid and 24mcg T3 (Cytomel) so I’m wondering is that about right ratio ? And is it better to dose throw-out the day the T3 breaking it up three x a day or more ? And I do it sublingually . Thanks to you Janie .

    Reply
    • Janie Bowthorpe

      Most patients on T3 multi-dose it since it has a short half life. We don’t look at ratios. We look at whether it’s putting our free T3 towards the top part of the range.

    Hi. I have been on levothyroxine .075 mg for many years. I was diagnosed with high liver enzymes. I have been asking my doctor to switch my med to a natural med but they will not. I know that the med is hurting my liver but they deny it. Please, does anyone know of a great doctor in the Saginaw, Michigan area that will change my med before it is too late? Thanks for your help.

    The article you quote establishes a link between hypothyroidism and liver disorders. Your claim that this is caused by levothyroxine is *consistent* with the article, but so is the claim that the hypothyroidism itself leads to liver issues.

    I should also note that not only has a link between levothyroxine and liver disorders *not* been established in the article, but your claim that there is a *causal* link is a very strong claim to make. Causal links are notoriously difficult to establish in science. I would be very careful about making such claims, especially when it may cause people to neglect their medical treatment.

      Hi Greg. The reason this old blog post mentions a link between the two is based on the reports of many hypothyroid patients over years who found themselves with fatty liver disease while on T4-only, yet saw it go away once they got on an optimal dose of NDT.

      So when studies come up (May journal issue of Hepatology, published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases, and similar results reported in the Journal of Gastroenterology and Hepatology 2005), and when we see reports of liver issues in a lot of patients on T4-only which seem to go away while on optimal amounts of NDT, we think this is important to mention for anyone to consider.

      And Greg, “science” has failed thyroid patients repeatedly in certain areas. There is plenty of “science” which implies that T4-only is a satisfactory treatment, yet when we hear from patients all over the world who for years and years report problems on those same meds, we lose respect for much of so-called “science” in this area.

      Finally, no one is recommending people to neglect their medical treatment. Instead, the information in this article points to considering a different thyroid treatment with NDT (or even adding T3 to one’s T4) based on what having direct T3 in one’s treatment has done for people in such a positive way.
