Are You Going Hot & Cold On Thyroid Cases?

What’s the most common thyroid disease you’re seeing in practice?  Nope, try again. I’m serious.  There would be very few of us who’d get this right without cheating. It’s nodules.  Current figures suggest 1/2 of all us middle-agers have them and by the time we’re 80 that’s risen to 90%!  There’s a school of thought that says these figures have jumped purely because of increased rates of thyroid imaging and we should stop sticking our nose in places it doesn’t belong. Just because they are there doesn’t mean we need to know about them or that they are causing trouble. All this is true and yet there is a percentage of patients for whom these nodules are a whole lot of trouble, in fact, that’s why they’re coming to see you…they (& possibly you!) just don’t know it yet.

Nodules, outside of radiation exposure, have always been primarily viewed as a nutritional deficiency disease: Iodine.  While this was always a bit one-dimensional (poor selenium…when will you ever get your due?) it’s an explanation that no longer fits as well as it once did because even in populations who have addressed iodine deficiency, the incidence of nodules continues to rise. 

So, what now?

New nutritional drivers have been identified but rather than being about our deficiencies they speak to our nutritional excesses.  And while iodine is not totally out of a job here, some people of course are still experiencing long-term suboptimal iodine which can trigger nodule development, we now need to question if there is any therapeutic role for iodine once the nodules are established. Well the answer is both ‘yes, maybe’ and ‘absolutely not’. The determinant being whether we’re dealing with Hot or Cold Unfortunately most patients and therefore their practitioners can’t tell the difference. But it is the presence or absence of a hot nodule that radically changes what complementary medicines you can and can’t use and what an effective treatment plan looks like.  

I’ve seen a lot of thyroid nodule cases pop up in mentoring this year and it’s been a great learning opportunity for everyone to get comfortable with clues in both patients’ presentation & their pathology. While iodine deficiency no longer ‘fits’ like it did, nutritional medicine should arguably remain the primary approach to their management and the new research gives even more credence to this and  identifies a far greater range of dietary and supplemental tools.

Thyroid nodules are going to explain a surprising number of our subclinical (hypo and hyper) thyroid patients and we already have a dispensary full of powerful interventions but we need to start by familiarising ourselves with their story: their why (they happen), their what (this means for patients) and their how (on earth are we going to address these effectively) Knowing your Hot from your Cold…is step one.

 An increasing number of our patients have thyroid concerns but unbeknown to many of us the most likely explanation of all is thyroid nodules, whose incidence is on the rise globally.The development of nodules has always been primarily viewed as a nutritional disease. Traditionally attributed to chronic iodine deficiency but recently novel nutritional causes have emerged . Benign nodules come in 2 flavours: hot and cold and while patients can present with a mixture, it is the presence or absence of a hot nodule that radically changes what complementary medicines you can and can’t use and what an effective treatment plan looks like.  The pointers, as is often the case, are there for us in the patient’s presentation and pathology, so knowing the difference is no longer a guessing game. This UU30 comes with a great visual clinical resource and includes key papers on the nutritional management of nodules.

You Record Something Then This Happens…

I had to say to a mentee just yesterday, “You’re going to see the topic for the Update in Under 30 this month and think it’s inspired by your patient but it was actually about the 3 other cases I’d seen this month, before yours!”  Yep…I’m talking about thyroid nodules, which happen to be hot (pardon the pun) right now.  But they’re not always hot, right? I mean, they are always a good topic for discussion because so many of our clients thyroid issues are due to these but nodules come in 2 flavours: hot and cold.  And knowing the difference is about as important as knowing your left from your right 🤲

“Oh Iodine the panacea of all things thyroid (tongue firmly in cheek) – can you fix nodules as well?” chorus the masses

Honest (salt of the earth!) Iodine Replies, “No & in fact I may make some nodules worse!”

Sorry for the re-enactment of this little local theatre piece in my head…it’s been a big week. Hence the marionette…ah yes it’s all becoming clear now 🙄 But it seems this isn’t common knowledge because a mentee presented a case this week of a 39 year old female who has confirmed multiple thyroid nodules that had prior to seeing her, seen another practitioner who put her on high dose iodine with the reassurance “there’s nothing wrong with your gland that iodine can’t fix”..or something to that effect. Oh boy 🤨

“Tell us! Tell us what happened next!” the chorus chants

Well it looks like as a result of the iodine, her cold nodules just might have switched to hot…that’s bad news all round I am afraid 🙁 But if we all knew our nodule nutrition better, this wouldn’t happen.

Are We Missing A Different Kind of ‘Hyper’ Child?

 

Stop press. No, seriously.  This new research warrants the attention of every practitioner working with children & teenagers. In the largest paediatric study of its kind to date, which included 2,480 children aged 10-18yrs diagnosed with hyperthyroidism (Grave’s or otherwise), Zader & colleagues found

Double the rate of ADHD diagnoses  
5 times the rate of Bipolar diagnoses (almost 7 times in males)
 5 times the rate of suicidality
That’s what I said: in 10-18 year olds 

What is most alarming of course is that these mental health diagnoses were made in half of these children >3 months prior to the diagnosis of hyperthyroidism.  What does this mean?  It means we are missing this critical biological driver in this patient group. We all recognise the potential for some psychological presentations people affected with thyroid conditions, however, perhaps we are more alert to this in adults and letting it slip off our radar in kids? There’s been renewed talk about the over- and mis-diagnosing of ADHD lately and given that research has found up to 80% of hyperthyroid children meet ADHD diagnostic criteria this is one of the 1st place arguably to look! It also means, as these researchers discuss in detail, these kids are being medicated with psychiatric meds that in fact may, at the least mask their abnormal thyroid, lead to the incorrect diagnosis of hypothyroidism (lithium & even stimulants for example) or exacerbate their hyperthyroidism (quetiapine). But wait there’s more and it’s essential to understand.

Zadar & colleagues note that while we can not be 100% clear about the direction of the relationship…e.g. were these children already at risk psychologically and the hyperthyroidism just exacerbated that, they note that correction of the TFTs does not always equate to ‘cure’ of the mental health issues.  This is not entirely surprising of course. What the problem emerges via a combination of biology and psychology & we resolve or remedy the biology…guess what you have left? PLUS the learned behaviours etc from suffering from anxiety, impaired cognition, suicidality they’ve been battling at the hands of excess T3 and a subsequent tsunami of reactive oxygen species.

This is one of those papers we should all have to read top to toe and therefore ideally be able to access for free but alas 🙁  What you can read is the Medscape review of this, which is a reasonable summary but the full paper is worth it if you can. You know the other key take home here…the diagnosis of hyperthyroidism was only made with overt out of range TFTs… which begs the question what about all those subclinical hyperthyroid cases we know exist?  Yes, no wonder this paper has RACHEL’ S FAVOURITE written all over it…paediatric thyroid assessment and missed biological drivers of mental health and the opportunity to get better at both…can my research reading get any better this week?!🤓

 Do you know how paediatric thyroid assessment differs from adults? Thyroid Assessment in Kids & Teenagers – Why, When & How

Currently in Australia there is limited use of age specific reference ranges for thyroid parameters in children & teenagers yet they are essential for correct interpretation and diagnosis. Even doctors & specialists seem to be at a loss with diagnosing thyroid problems in kids unless they are extreme presentations. Subclinical thyroid presentations, however, are increasing in both children and adults. Many practitioners competent in adult thyroid identification & management are less familiar and confident with knowing when why and how to test in this population. Make sure you’re not missing thyroid imbalance in your paediatric patients…early detection makes treatment easy.

Lots to be Said for Boring Basics

Horses not Zebras.  You’ve no doubt heard me repeat that quote which is famous in medical schools, something to the effect of, “When you hear a heard of animals outside your door, think horses not zebras”…unless of course you are practising in Africa might I suggest 😉 This of course reminds us all in short to think of the most likely explanations not the most exotic first. Likewise with our case taking. The number of times I ask practitioners for the ‘boring basics’ and am met with an embarrassed silence.  Think:

Body Mass Index

There I said it…and yet these are like dirty words in integrative health.  Why? Because we’re starting to ignore the ‘boring basics’ in favour of getting ‘fancy first up’, as I like to call it.   Look I love a good bit of bioelectrical impedence assessment as much as the next clinician and I am not about to use this crude measure as replacement for that but I absolutely need to have these key landmark pieces of information to understand a very long list of things such as contribution to future health risks,  current burdens from literally the weight on those joints leading to knee pain, to the weight/mass not pulling on their bones and therefore contributing to lower BMD their whole life. Even their likelihood of a leaky gut today, right, Brad Leech, our colleague and impressive IP researcher?  BMI drives also the appropriateness and their capacity for any exercise interventions I might recommend, not to mention the frequently mentioned, accurate interpretation of their labs. 

For many many labs that we routinely see for our clients…the reference range should actually be a sliding scale that moves with BMI…what do we really ‘expect’ and what is actually ‘healthy’ is different at different weights. 

Like TFTs – this may be a big newsflash for most but I never want to see a patient with a BMI > 30 have a TSH anywhere < 2, unless they’re on replacement.

 Say wha? You heard me. I promise I’ll tell you more about that soon.

But again…let’s not get fancy first up especially not in any of our paediatric patients and in spite of what their words or ‘tude may be telling you, that includes all the way up to 18 in our books! Brace yourself, I’m going to speak that dirty word again…BMI..boring basics before all else. We need to review their height, weight and BMI against paediatric growth charts.  These oldies are goldies and can reveal so much about growth trajectories, puberty milestones when any other discussion is off the table,  type 2 nutritional imbalances (protein, zinc, potassium, magnesium, sulfur) and flag all other sorts of concerns or reassurance…and you haven’t had to steal a drop of blood or any much hard earned money off mum and dad to work a lot out. Anyway,  that’s my ‘boring basic beef’ for now…there’s a lot to be said for ensuring such ‘dirty words’ come before everything else.

Need help with wrestling all the most important patient information into a clear management plan?

As integrative health practitioners, we pride ourselves on taking in the ‘whole health story’ as a means to accurately identifying all the contributors & connections to each patient’s presenting unwellness.  In the process, we gather a wealth of information from each client  – pathology, medical history, screening tests, diet diaries etc. that borders on information overload and often creates so much ‘noise’, we struggle to ‘hear’ what’s most important. The management of complex patient information and the application of a truly integrative approach, requires due diligence and the right tools. Mindmapping and Timelines are two key tools to help you go from vast quantities of information to a true integrated understanding of what is going on in the case and the more time we spend learning and applying these tools, the more they will write the prescription for you. Not just for today but for the next 6-12mo for that patient.

 

Double Trouble for Hypothyroid?

So we already know that thyroid problems can start in utero, right…but a recent Medscape review (the fountain of thyroid information that I frequently drinketh from 😉 ) on Hypothyroidism in childhood taught me a couple of big things I hadn’t known before! 

The diagnostic criteria for subclinical hypothyroidism are raised TSH levels in combination with a normal concentration of free serum thyroxine (FT4) but because there are some differences between accepted ranges in TSH assays, high-risk groups should be screened, especially babies with malformations, whose mum received steroid treatment during pregnancy or in the neonatal period, or who had existing thyroid dysfunction, TFTs (or at the least TSH as part of what’s called the Neonatal Screening test) should be repeated 2 weeks later. But now comes the couple of big light-bulb moments: the incidence of eutopic thyroid in twin births is nearly double compared with singletons! As you know, I’m a mother of twins and I’m guessing at 18yrs old now (and multiple peachy TFTs 😉 ) the horse has well and truly bolted for my two but geez…I had no idea of the dramatic increase in risk. And it keeps going…monozygotic twins very commonly show a delayed TSH rise and those numbers are even more prominent in multiple births. The other not-so-fun-fact is the discovery that subclinical hypothyroidism in IVF babies is approx. 10% which is noteworthy considering none were observed in the control group.

This obviously left me thinking “W.H.Y?” And of course…the first place my head goes with the latter…is iodine.

Could this phenomenon in IVF babies be due ultimately to undiagnosed or poorly managed SCH in mum or even simpler still, just basic iodine deficiency, presenting as infertility?!

The reasons behind our increasing rates of thyroid dysfunction across the life-stages are multifactorial (and don’t get me started on the very real contribution of EDCs!) and how, in spite of iodine adequacy being the first thing on the checklist for thyroid health, so many health professionals ignore this, at their patients’ peril… But now at least we know that patients with IVF babies, twins, and preterm bub, who are currently not included in the prioritised screening groups should be…and of course we should keep asking the questions, “what are the mechanisms behind this, why is it so?”

So if this has made you even more curious about the incredible butterflied-shaped gland and you’d like to go for a stroll on the vast plains of “thyroidisms” you can click on this link Thyroid Assessment in Kids and Teenagers and get completely “thyroided” up. There is always more research to come our way so keep your eyes and ears peeled.

Thyroxine Replaced Patients Left To ‘Set & Forget’?

One tree in field

Too many times we see thyroxine treated patients on the ‘set and forget’ setting. Often, they’re taking the same dose they started on a decade or so ago, in spite of weight changes, ageing of course and new comorbidities. They’ve undergone limited monitoring, with just an annual in-range TSH viewed as confirmation of efficacy.  But is it? Many patients’ re-emerging hypothyroid signs and symptoms would suggest not.

A recent Medscape review article of a large study by Gullo et al 2017, identifies another shortcoming in the rudimentary way we ‘replace thyroid hormone’, in all patients but especially in those who’ve had their thyroid removed. (more…)

Iodine Deficiency May Impair Ability to Conceive…Who’d Have Thought!

“Researchers followed more than 500 women trying to conceive over about five years and found that, overall, those with moderate to severe iodine deficiency had 46% lower odds, per cycle, of becoming pregnant.”

All researchers dream of generating the kind of results that are ground-breaking but sometimes you read about the latest study’s findings and you  think, ‘Really, you spent all your time & cleverness for years on this and that’s all you have to show for it!’ Like the study that finally confirmed dog’s can feel empathy (at last thank goodness …phew…cos I had my doubts until they crunched the numbers!)

So too a study published this month on the possibility that iodine deficiency is common in women trying to conceive in developed countries and may be connected to increasing fertility issues.

Stop press!  I know…that made you spill your coffee! (more…)

No Holiday For The Thyroid

Just because most of us have been on holidays doesn’t mean the thyroid knowledge wagon has stopped or even slowed!  Always amazed at what we continue to discover about the complex working of this amazing gland and how its health impacts so much of the rest of the body and of course our babies’ bodies! So I thought I’d give you a quick recap of an important study published while you were at the beach/in the bush/in bed ;)…

  • A Finnish prospective cohort study of over 3000 pregnancies by Heikkinnen et al has revealed that at 16yo, offspring from these pregnancies, had a 1.56 increased rate of unhealthy weight and a 2.5 greater likelihood of meeting criteria for metabolic syndrome, if their mothers were thyroperoxidase antibody (TPO) positive during their first trimester
  • TPO antibodies affect up to 20% of pregnancies but in this study they defined ‘TPO positive’ as those women with levels ≥ 167.7 IU/mL (the 95th centile in this sample)
  • What adds to the noteworthiness of this news is that:
    • More than half (55%) of the TPO positive mothers were classified as euthyroid during their pregnancy, suggesting that the effect was not driven by maternal  hormone concentrations
    • The offspring of mothers with actual thyroid dysfunction did not show any statistically significantly greater risk of cardiometabolic issues
    • The offspring of hyperthyroid mothers in fact demonstrated significantly better insulin sensitivity at 16yo than children of euthyroid mothers
    • Thyroglobulin Abs over the 95th centile (≥ 47.7 IU/mL) did not correlate with any increase in cardiometabolic risks for their children

When we consider the substantial evidence of poorer maternal cardiometabolic outcomes for women who are hypothyroid during pregnancy – it would seem that the abnormal thyroid hormones are most impacting for mum but in fact the TPO Abs the most detrimental for bub! (more…)

Hypothyroid Without a Trace?

 

Another young female presents in my clinic with a newly diagnosed thyroid cancer and has been recommended urgent thyroidectomy.  Her story is increasingly common. If you’re not seeing it in your clinic, you will, because thyroid cancer, and almost exclusively papillary thyroid carcinoma (the form my patient and most young patients have), is dramatically increasing.  Since the 1970s there has been a 67% increase in the incidence in women and a 48% increase in men documented in 5 continents (Peterson et al 2012).  Australia, though less up to date with its data collection, found a similar increase between 1982-1997 (Burgess 2002). The question begging to be answered is why.

Increased screening and more effective detection of smaller tumours was the going theory for years.  New research rejects this absolutely and concludes instead this is a ‘true increase in occurrence’.  Increased radiation exposure?  Mutation studies say no.  Many researchers are pointing to is a ‘new environmental chemical and/or dietary factor’ and EDCs (Endocrine Disrupting Chemicals) that target the thyroid such as perchlorates, phthalates, parabens and phenols are the likely suspects. And, more than likely, with iodine deficiency to explain the increased susceptibility to these EDCs.

But wait there’s more. These ‘new goitrogens’ aren’t only implicated in thyroid cancer, a large number of human studies confirm the higher your urinary metabolites of these, the lower your thyroid function. More worryingly is that they might be doing this ‘without a trace’. With myriad impacts at the receptor level, altered hormone excretion rates, impaired peripheral conversion etc. the data to date suggest these patients TFT results might only look ‘slightly low’ or even ‘normal’ but the reality is they are suffering hypothyroidism. Sound familiar?

There is a HUGE body of scientific evidence we can pull from to understand the role of EDCs in thyroid problems in our patients, how to maximise prevention and minimise impact – even when your patient, like mine, is perhaps already in the full grip of the consequences.  I’ve read all the papers and summarised them in this 30min recording:  Hypothyroid without a trace – the role of EDCs.

Have you got patients with hypothyroid symptoms but normal results?  Or results that suggest the HPT axis just seems to be broken? Could it be the result of a combination of Endocrine Disrupting Chemicals (EDCs)? How do you assess  for these ‘new goitrogens’, which act more potently and more insidiously, inducing hypothyroidism ‘without a trace’. How do you maximise prevention for all of your clients and the most at risk sub-populations or minimise impact for those already in the full grip of their consequences.
 
This latest Update in Under 30 audio comes with 3 key related scientific articles and a bonus larger powerpoint presentation that Rachel presented at the ASLM 2017 conference.

Let’s Stop Normalising Abnormal Breasts

Breast boxer

Let’s play a little word association game:

I say ‘Fibroids’ – you say, ‘Oestrogen’.  

I say ‘Cyclic Breast Pain’ and you say, ‘Ouch!’ [because it just slipped out] but then you say, ‘Prolactin’, right?  Me too. 

Prolactin driven breast pain’s most characteristic form is the premenstrual ‘oh my goodness get these off me!!’ kind, with patients experiencing anything from burning, aching, bruised feelings and acute hypersensitivity to touch, which builds in intensity for days leading up to their bleed. Of course cyclic mastalgia can progress to being full-time mastalgia in women whose breasts start to exhibit structural tissue change in the form of cysts, fibrosis and ultimately fibrocystic breast disease.  If you’ve ever experienced even a day of mastalgia it is truly hard to conceive there are so many women (about 50% of premenopausal women!!) living with it daily.

Adding to our concerns about this so-called ‘benign breast disease’ (BBD) is that researchers are now certain it’s a significant risk factor for breast cancer, with women with any form of BBD experiencing at least a doubling of risk of a subsequent breast cancer diagnosis, while those women with proliferative BBD exhibiting a risk of 3.5X that of women without BBD.  Castells et al 2015  (more…)

Pig Thyroid For Who?

pigGot any patients on Natural Thyroid Extracts (NTE)?  Me too…and I am finding it’s on the increase.  What’s the deal?  What do we need to understand about this form of thyroid replacement therapy to best monitor and manage those patients already on it or contemplating taking it? Does it really offer advantages to all hypothyroid patients or just to a subset of those and how would we recognise these people who might benefit the most?

NTE are marketed as being superior to synthetic thyroxine primarily based on the fact that they provide the patient with some T3 as well as T4 and in addition to that, being extracts of pig thyroid glands, there are other thyroid and iodine based actives e.g. mono and diiodotyrosine, present in the extracts.  So in essence this is giving us more iodine and more of the other ingredients we need to make our own thyroid hormones.  Based on this, many proponents of NTE say this is a major advantage over synthetic thyroxine replacement because it is more ‘holistic’ and it supports the patient’s gland in its own hormonogenesis.   (more…)

Digging Deeper Into Thyroid

digging deeper

Have you still got some thyroid patients that don’t fit any sort of traditional thyroid disease model and are difficult to get results with? Oh yes me too… and watch out…I’ve been spending the last few weeks with my nose firmly embedded in hundreds of articles digging around for more answers. As I am presenting on thyroid conditions for ACNEM in Adelaide March 18-19th, I couldn’t resist going back to the literature to see if by delving a little deeper again I could come up with some more answers to these weird, wacky and hard to treat thyroid presentations that we’re increasingly seeing and guess what…I think I’ve found a few gems.

When I Would Give Withania A Miss

stop-1077973_960_720

We kicked off mentoring this year with some great cases last week.  One was a pregnant hyperthyroid client.   During the session the wonderful practitioner mentions that the client is using Withania somnifera as required for anxiety.

Insert sound of brakes screeching to a dangerous squealing crash!  Here’s a situation where I would give Withania a miss.  (more…)

Avoiding Overwhelm In Clinic

So…a 40 something female walks into your clinic with depression & anxiety…sounds common enough right?  But here’s the twist: she’s already seen another practitioner who ran a range of investigations revealing she has pyrroles, high copper levels & is homozygous for the C677T MTHFR mutation. Her medical history includes significant use of Ecstasy and a partial thyroidectomy due to nodules & she has persistently high TSH.  But wait there’s more!…The first practitioner upon discovering all of this put the patient on 12 different products which included zinc, B6, evening primrose oil, vitamin D, thyroid support etc etc.  And guess what…the patient feels worse!

Frequently our patients are just as complex as this case & sometimes our attempts to narrow the treatment focus through thorough investigation instead leaves us feeling we now have even more things we need to deal with than before! Feeling overwhelmed?? Often! At risk of completely overwhelming the client as well?  Definitely!  And a reflex to throw your whole dispensary at a client never ends well. (more…)

Iodine Excess in Action

 

I’m only human & there are some questions that do make me silently groan & invisibly (I hope!) roll my eyes.  One is the old chestnut:  “but the Japanese consume on average 7mg of iodine a day!” which is typically offered up as a rationale for the need for mega dosing of iodine in everyone.  This is of course only a partial truth & the missing bits make all the difference!  The Japanese have some of the highest rates of thyroid disease in the world & this is in part, attributed to their high iodine exposure.  Secondly, it’s simplistic & flawed to isolate one characteristic of a whole diet & not appreciate that its effect or impact is mitigated by the context of the entire diet & lifestyle of that population.  In the case of the Japanese, for example, this includes relatively intake of isoflavones, key goitrogens which will reduce the bioavailability of the iodine both within the gut & at the thyroid. Harrumph!  I love iodine & am frequently suspicious of a deficiency in my clients, however, like many nutrients feel that our ultimate objective is for optimal nutrition…not excessive.

Am I just a conservative scaredy cat perpetuating fear around this topic in the industry?  Well…..no.  There is accumulating international evidence of big spikes in autoimmune thyroid disease diagnoses following the introduction of iodine fortification programs in previously iodine deficient countries such as Greece, Turkey & Brazil.  There is of course evidence as well that iodine supplementation in Grave’s & Hashimoto’s disease can lead to delayed recovery or worsening of the condition. (more…)

Optimal Thyroid Function In Pregnancy?

Thyroid function is critical to successful conception, healthy pregnancies, babies and mum’s post-partum wellbeing, so we need to take the time to ensure we’re monitoring it properly.

First of all you need the right tool for the right job & that means we need trimester specific reference ranges – which unfortunately many pathology companies don’t use in Australia.  Due to the thyrotropic action of HCG (acting a bit like TSH), TSH should actually decrease in the 1st trimester and while TSH is less affected in 2nd and 3rd trimesters it should still actually sit lower than in non-pregnant females.

An Iodine Revolution?

Also presenting at the Science of Nutrition in Medicine Conference this year was Professor Eastman who is a world-renowned Australian endocrinologist with a primary interest in global iodine deficiency. He is also Deputy Chairman elect of the International Council for the Control of Iodine Deficiency Disorders (ICCIDD) and is frequently consulted by Australian health authorities and medical groups on the issue of iodine deficiency in Australia.  Boy did he have some things to say…and it kind of went like this:

  • Substantial epidemiological research has shown that 95% of euthyroid patients have a TSH between  0.04-2.5 mIU/L  (note the current reference range suggests results < 4 mIU/L are okay, Eastman strongly refutes this)
  • The mean TSH in a disease free population is actually 1.5 mIU/L
  • In fact Professor Eastman was emphatic that the mean TSH in iodine replete individuals is actually 1 mIU/L
  • While acknowledging the limitations of spot urinary iodine testing for the assessment of individual iodine status, he genuinely seemed at a loss to understand GPs reluctance to refer for this test when patients exhibit risk factors for hypothyroidism and in his article (Screening for thyroid disease and iodine deficiency. Eastman CJ. Pathology. 2012 Feb;44(2):153-9.) he argues strongly for screening of all mature age women, pregnant women (1st trimester) and school children, using the urinary iodine and TSH together
  • And while we’re stirring the pot how about this: Professor Eastman says that hyperthyroid individuals who have a low urinary iodine result should still be given judicious iodine! Such sacrilege!!
  • But wait…before you get too excited and join the ‘too much iodine is never enough… just look how much the Japanese eat’ camp…I was very relieved to hear Professor Eastman remind the audience that while the Japanese diet does provide substantially more iodine than the Western one, it is not without problems, with very high rates of thyroid disease especially thyroid cancer and in fact, Japanese health authorities are concerned about excessive intake and are currently investigating ways to cut back.  And lastly, if you’re not convinced by this, he says perhaps you should talk to one of the many litigants in the current class action against Bonsoy, who developed severe thyroid diseases thanks to excessive iodine exposure from the milk (7.5mg/cup)!

So keep arguing for urinary iodine assessment and for addressing individuals with ‘within range reference results’ for TSH that are clearly not healthy ones.  Check out Professor Eastman’s article, there’s a goldmine of information in there and while we’re talking about incredible resources in nutritional medicine – take a moment out to thank Dr. Tini Gruner (previously from Southern Cross University) for her significant contribution to naturopathic nutrition education in Australia.  She was a mentor and inspiration to me and many others. She sadly passed away this week and we will miss her dearly.
