You have a T4/T3 conversion doctor on the NHS? Amazing they did your FT3!

Your FT3 level is only at 19% so you really need a dose increase of 25mcgs.

RT3 test is not so popular these days as there are many many causes of high RT3.

I would say you are symptomatic because your TSH is too high. It should be 1 or less when being treated. There is room for an increase in Levo. This may also bring up your FT3 which will help with your symptoms.

Some members will come along and give links to guidelines that you can show your GP. You will have to be your own advocate.

No you don't need rT3 done , its very expensive and even if it's high there can be a multitude of reasons for it ... if the cause is 'too high T4' you can see that by looking at fT4 / fT3 tests .

Time of day affects TSH result , early am highest >>> early / mid afternoon lowest .

Those TSH results from Oct / Dec 2021 were done when it was lowest .. if done at 9/10 am they would have been higher.

.....What time of day was this latest TSH result of 2.97 taken ?

Show your GP this list of recommendations advising GP's to keep TSH below about 2/2.5 in patient taking Levo ( some written specifically for GP's by NHS registrars in Cardiology and Endocrinology) healthunlocked.com/thyroidu... my-list-of-references-recommending-gp-s-keep-tsh-lower

and use it to ask for a trial increase in Levo dose to 112.5mcg or 125mcg for 6 months .. to see if it improves your remaining symptoms .

How long have you been on propranolol

On all these tests?

Breathlessness is frequently low iron/ferritin

Get full iron panel test for anaemia including ferritin

Always do iron test early morning, and just water before test and don’t eat iron rich dinner night before test.

Medichecks iron panel test 

medichecks.com/products/iro...

also need to test BOTH TPO and Tg thyroid antibodies privately

is it necessary to have RT3 test done if ratio T4/T3 is low?

No. There are many reasons for raised rT3 and only one of them is connected to the thyroid. Testing can tell you if it's high but can't tell you why so it's a pointless test that's not worth spending money on.

An excess of unconverted T4 can cause high rT3, your FT4 is too low for this to cause high rT3. The other conditions that contribute to increased Reverse T3 levels include:

· Chronic fatigue

· Acute illness and injury

· Chronic disease

· Increased cortisol (stress)

· Low cortisol (adrenal fatigue)

· Low iron

· Lyme disease

· Chronic inflammation

Also selenium deficiency, excess physical, mental and environmental stresses. Also Beta-blocker long-term use such as propranolol, metoprolol, etc. Physical injury is a common cause of increased RT3, also illnesses like the flu. Starvation/severe calorie restriction is known to raise RT3. Diabetes when poorly treated is known to increase RT3. Cirrhosis of the liver. Fatty liver disease. Any other liver stress Renal Failure. A fever of unknown cause. Detoxing of high heavy metals.

Your results clearly show that you are undermedicated to have a TSH level of 2.97, an FT4 that is only 54.55% through range and an FT3 that is 18.92% through range.

The aim of a treated hypo patient on Levo only, generally, is for TSH to be 1 or below with FT4 and FT3 in the upper parts of their reference ranges.

Did you do the test as we advise:

* No later than 9am

* Water only before the test

* Last dose of Levo 24 hours before test

* No biotin, B Complex or any supplement containing biotin for 3-7 days before the test

If so then your results suggest that you need an increase in your Levo, 25mcg now, retest in 6-8 weeks, possibly followed by a further increase until levels are where the need to be for you to feel well.

Are your Vit D, B12, Folate and Ferritin at optimal levels, this is needed for thyroid hormone to work properly and good conversion to take place. If not tested then it would be a good idea to do this now.

Test was 9:30am and I had a coffee, I had stopped Biotin and vits OK, selenium is non existent though as had this condition since birth.

SeasideSusie profile image
SeasideSusieRemembering in reply toStace268

Stace

We always suggest no food or drink except water before thyroid tests so that nothing interferes with the results.

Coffee is said to interfere with blood test results

healthline.com/health/fasti...

Can you drink coffee if you’re fasting before a blood test?

Even if you drink it black, coffee can interfere with blood test results. That’s because it contains caffeine and soluble plant matter, which might skew your test results.

selenium is non existent though

Have you tested and know that your level is non-existent? Are you supplementing? Selenium is important for thyroid function.

tattybogle profile image
tattybogle in reply toStace268

"selenium is non existent though as had this condition since birth."

"Selenium came up as 0 when I had it tested because I thought I had thyroid eye disease"

What condition have you had since birth ?

have you had low / '0' tests for selenium previously ?

Selenium is a vital part of the process for thyroid hormone production AND for conversion of T4 >> T3. without it the deiodinases (DIO1/ DIO2 ) will probably struggle to convert T4>>T3 properly

(i say probably because . selenium together with iodine play a very complex role in this process and most of it is 'over my head' )

Do you supplement with selenium ?

Yes and had extra selenium and zinc vitamin as well. Had anemia as child and undiagnosed hypothyroidism

Hello Stace :

I'm not aware the NHS test or recognise Reverse T3 - and they are not obliged to accept private blood test results and they refused to accept my complete thyroid blood tests to include a Reverse T3 some 6 years ago.

In order for T4 monotherapy to work effectively we do need to maintain optimal levels of ferritin, folate, B12 and vitamin D :

Once these vitamins and minerals are at good levels and your core strength strong and solid you will be better placed to build up our dose of T4 into the top quadrant of the range as then the conversion to T3 - the active hormone - should improve to around 60/70% through it's range.

The accepted conversion ratio when on T4 monotherapy is said to be : 1 - 3.50-4.50 - T3/ T4 with most people feeling at their best when they come in this ratio at 4 or under.

We generally feel better when the TSH is low in the range and definitely under 2 and more probably under 1 and this will happen with slow steady increase in T4 - Levothyroxine at 25mcg increments and a blood test follow ups every 6- 8 weeks to follow your progress and hopefully to the relief of symptoms.

The conversion ratio doesn't really apply at this point in time as your T4 is not in the top quadrant and when there are insufficient thyroid hormones circulating the body prioritises T3 over T4 so your current conversion ratio 17 divided by 3.80 - is not a true reflection of your ability to convert T4 into T3.

Do you have any recent vitamin and mineral blood test results as forum members can advise of where these need to be as some of the NHS ranges are too wide to be serious.

OK just for reference I know now that I need to maintain my vitamins and minerals at the following levels to feel well and able to convert T4 into T3 :

I need a ferritin at around 100 : folate at around 20: " serum " B12 at 500 ++ and a vitamin D at around 100:

suggest you change vitamin D supplement

Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.

There’s a version made that also contains vitamin K2 Mk7. 

One spray = 1000iu

amazon.co.uk/BetterYou-Dlux...

Increase to 2000iu and retest in 3-4 months

Test twice yearly via NHS private testing service when supplementing 

vitamindtest.org.uk

Aiming for at least over 80nmol and between 100-125nmol may be better

Stace268 in reply toSlowDragon

My doctor prescribes the Vitamin D and I know I have low stomach acid so it's very probable I have absorption issues. Though it was at 25mg at one point and now 69 so it must be working slowly. GP also told me too much calcium is bad for heart, I believe she's trying tell me something.

Oh dear another clueless medic!!

You need to optimise vit D, vit B12, folate and ferritin to support T4 to T3 conversion/ thyroid function....it will take a littlt time to raise levels so be patient

Low essential nutrients impair conversion

Poor conversion can be identified simply .....high FT4 with low FT3

Your levels are going in that direction....but this can be reversed with corect treatment

T3 is the active thyroid hormone and for good health must be available in an adequate and constant supply

Low cellular T3 = poor health

Your FT3 level is abysmal!

FT3 followed by FT3 are the important readings....TSH is not a reliable marker....see link below.

100mcg levo is not providing the hormone level you need and I suspect your nutrient levels are low

Weight gain is a symptom of hypothyroidism/ undermedication

First you need to raise levo to 125mcg along with any deficient nutrients ( above) then after 6/8 weeks on a steady dose test again.

You still have plenty room to raise levo to 150mcg if FT3 is still too low......both FT4 and FT3 should be approaching 75 % through the ref range...we are all different so this will vary.

Listen to your body it will tell you when treatment is working....or not

If that does not adequately raise FT3 and improve symptoms then you may need to add a little T3....but you are not at that point yet

Your GP will most likely wrongly focus on TSH and bang on about overmedication because your TSH has fallen....rubbish!

This link will explain and help argue your case if TSH becomes an issue with your medics

thyroidpatients.ca/2021/07/...

As for rT3....it is basically the body's way of getting rid of excess T4....it can rise when FT4 is not being adequately converted but it is transient and is fairly quickly metabolised and excreted. Expect rT3 to be low if FT4 is low. Don't worry about it....correct medication will resolve this. Testing is expensive and not needed!

The NHS report above is wrong to say no further action needed....initially you need more levothyroxine

"Normal" only means in ref range. it does not mean that your results are optimal for you as an individual....it is a pointless term

Just a few thoughts!

Stace268 profile image
Stace268 in reply toDippyDame

I know this but how can you make a doctor retest in 6-8 weeks to get results if they refuse and refuse increase

tattybogle profile image
tattybogle in reply toStace268

"how can you make a doctor retest in 6-8 weeks to get results if they refuse and refuse increase"

re. what to do it they refuse an increase when bloods clearly say there is room to try one safely ?

.. personally i "do it first and ask later" ..

eg i increase dose slightly myself for at least 6 weeks using the tablets i already have ( if i didn't have enough in hand to do 6 weeks i might accidentally 'leave a packet on holiday and request a 'replacement' doing this once will not be a problem . obviously it's not a way to get more long term)

increase by 12.5mcg (or 25mcg but no more) for at least 6 weeks (just before the next GP 'annual' blood test is due if possible, as then you don't even have to explain why you want 'another' blood test .... but if that is too far away just do it for 6 weeks whenever , and then say "i've tried increasing my dose and i feel better, can we check my bloods on it please" .. they will have to agree to do bloods then because they will be worried you are overmedicated )

Then book test and tell phlebotomist you have recently been trying an increase to 'x' so it's officially noted and GP will be informed of what you've done .

Then book appointment to "discuss result with GP" .. assuming the TSH is still in range and the fT4 is not over range .. the GP will have no legitimate grounds to ask you reduce again . and should be willing to increase the prescription officially to 'x'

obviously if the TSH is now below range and /or fT4 is over range , then you will be having a different conversation .. hence why it is better to only increase by 12.5mcg at a time..as it reduces the chances of the GP having a dicky fit

( it's a good idea anyway regardless of the GP's stress levels ... 12.5mcg IS enough to have an impact on symptoms .. and we don't want to be taking more than we need ....12.5mcg 'too much' can make you feel just as rubbish as 12.5mcg 'too little'

20 yrs ago i increased my own dose from 50 to 100 to 150 using this method .. (because i didn't know any better) . My TSH was in range each time and fT4 was not over range , so GP always said "ok ,carry on" ,

I would be more cautious nowadays and would have gone from 100 to 125 to 137.5.. as i've since learned that 12..5 mcg is enough to make a difference to symptoms , and i've also experienced overmedication (which is actually quite hard to spot when it come on gradually over several months) but is very unpleasant.

Stace268 in reply totattybogle

That all makes sense to me, though I was just going to mention the GP handbook on Thyroxine and I felt better when it was 1.44 in 2021 also I'm concerned of damage being under medicated. On a different note I read of someone has conversion issues too high T4 can be damaging as they pituitary can't convert it. Feel lost tbh and over and undermedicated are similar so you're right, though as with you unlikely I'm over.

tattybogle profile image
tattybogle in reply toStace268

pituitary doesn't really do 'converting' T4>>T3 .. (well every cell/ organ that has any thyroid hormone receptors must be capable of converting 'some' ... but conversion of T4 to T3 is a whole body thing involving lots of different organs and cells .. not so much a 'pituitary' thing .. if you see what i mean ) ~ edit * if you can you give a link to what you read i can maybe try and help understand what you read .

Anyway ... i really don't think you do currently have any issues with 'too high' T4

FT4: 17 pmol/l (Range 11 - 22) 54.55% ( thyroid.dopiaza.org/ % calculator)

if fT4 was 90% or 125% when fT3 was 18% ,that would be different ... but currently your fT4 is not even as high as high as many healthy people with no thyroid issue would have. Your fT3 will likely increase as your fT4 increases on higher dose .. if it doesn't and you have improved vitamins etc to optimal if needed .. then that is the time to start thinking about conversion .. and whether to investigate lower Levo with added T3.

P.s what's the issue with your selenium ? is it really "Zilch " or has it always been just low ? do you know why ?

Do you know selenium is an absolutely VITAL part of the (chemical /cellular /deiodinase ?) process of thyroid hormone production AND conversion ?

It's effects on thyroid hormone production and conversion are complex and mostly 'over my head' ..and Selenium interacts in a very complex way with iodine levels too .. (iodine is a whole other area that needs MUCH CAUTION as it also has a direct effect on thyroid function , and too much can cause just as many problems as too little.)

DippyDame profile image
DippyDame in reply toStace268

OK. Well, knowing is a good start...you have to use that knowledge to your advantage and beat them at their own game....many of us have had to do this....see Tatty's response as an example

Your post didn't say your GP was refusing to budge...you appeared to be asking about rT3 and conversion....hence my response. We need as much relevant info as possible to be able to help

Take control ...raise your levo dose yourself... you have plenty room to do this safely. If you feel better use that to convince the GP you need an increase...if he objects then ask him to explain what else could have caused improvement....bet he struggles!

You will not be overmedicated so long as FT3 is in range

Test privately....basic tests won't break the bank and will point the way forward

See another GP who may be more switched on

Speak to the Practice Manager and say you feel very unwell but your GP isn't listening to you and taking your symptoms into consideration....result you are undermedicated and unwell and your labs prove this

Raise the point about the importance of adequate T3....you say you know all about that so use that knowledge.

The GP is most likely struggling due to lack of knowledge and can only trot out the usual TSH drivel

As an aide memoir before an appointment make a list of all the points you want to raise so that you can have a well informed discussion with the GP.....and hope he is open minded.

Refer to the link I posted and use this Paper too , for ref..

DippyDame in reply toStace268

We try to, but I'm afraid we don't always have time to trawl through old posts so try and add relevant info in any queries you raise, with linksif possible....it helps us to help you.

I suspect you are overthinking some of this....suggest you concentrate on getting your levo levo increased which should help.

It's easy to feel overwhelmed if you try to sort out everything in " a lump". Tackle one thing at a time

I also suspect your Vit D is deficient...

The Vit D Council, recommends a level of 100-150nmol/L (40-60ng/ml),.. is your level within this parameter

Re selenium...Protein foods from animals are generally good sources of selenium. Seafood, organ meats, and Brazil nuts are the foods highest in selenium followed by everyday stap like breads, cereals, poultry, red meat, and eggs.

Selenium deficiency is rare worldwide, and it often takes years to develop. It usually only occurs in regions with severely low selenium content in the soil, Are you sure your result was zero?

Re Dio1 and Dio2 snps....we have already discussed this...see previous posts. You cannot alter your genetic make up but you can deal with the possible consequences of identified polymorphisms eg impaired T4 to T3 conversion by adjusting medication.

First, you need more levothyroxine as we have previously explained.

Stace268 profile image
Stace268 in reply toDippyDame

The picture aforementioned is within this post not an old one.Yes pretty sure it was 0 and like I said it's been present since birth so it's possible though not had it tested recently only few years ago.

I will and do want to concentrate on T4 increase though I think because of already developed heart disease and just GP awkwardness they're being difficult.

Yes vit now 69 (was 23) as shown in this post also.

Many thanks

You need full iron panel test for anaemia including ferritin

Vitamin D better at least over 80nmol and between 100-125nmol may be better

How much vitamin D are you currently taking

Are you supplementing magnesium too (in afternoon or evening at least 4 hours away from levothyroxine)

Stace268 profile image
Stace268 in reply toSlowDragon

800iug vit D3 plus normal amount in a multivitamin which includes magnesium in it. I've read and heard too much magnesium is bad for heart and drinking water has magnesium in, Yes take vitamins 4hrs apart from it. Not concerned about Iron panel, I said it was when I was a kid I had anemia and I never know what to ask for the GP does not really keep eye on anything even if specialist sends a letter I have to chase it up as they don't bother reading it.

SlowDragon profile image
SlowDragonAdministrator in reply toStace268

Never take iron supplements without getting full iron panel test

Multivitamins never recommended on here. Most contain cheap poorly absorbed ingredients and also anyone on levothyroxine doesn’t want extra iodine. Levothyroxine contains all the iodine you need

Suggest get a separate selenium supplement

And retest selenium levels in 6 months

Guidelines on dose levothyroxine by weight is that most people eventually need approx 1.6mcg Levo per kilo of their weight

15st = 95kg

95kg x 1.6mcg = 152mcg as the likely daily dose levothyroxine you might require

We ONLY increase dose by 25mcg a day

Get dose increase to 125mcg

Make sure both tablets are always same make

Which brand are you currently taking

Always Take levothyroxine on empty stomach and then nothing apart from water for at least an hour after

Stace268 in reply toSlowDragon

I forgot to say I take a separate methylated vitamin B complex and what does everyone else take in regards multivitamin do they use methylated? It's so expensive!

I do space everything out as im on propranolol and spironolactone but trying stop the propranolol completely as hinders conversion apparently.

Yes only take with water and leave for an hour.

I am take Mercury Pharma brand.

B complex Methylated
SlowDragon profile image
SlowDragonAdministrator in reply toStace268

Test folate, B12 and ferritin at least once a year

Test vitamin D (ideally) twice year

Supplement only what tests show you need

Typically that’s daily vitamin D, daily vitamin B complex (one with methyl folate) and daily magnesium

Magnesium best taken afternoon or evening, but must be four hours away from levothyroxine

Vitamin D…..dose required varies a lot between individual people

Likely to need higher dose if gluten free or malabsorption

Aiming for at least over 80nmol and between 100-125nmol might be better

Daily vitamin B complex should keep all B vitamins in balance and folate and B12 optimal

If vegetarian/vegan or malabsorption issues might need separate B12 supplement a few days a week

Similarly ferritin needs testing annually. If under 50 need full iron panel to see if iron also low. Aiming for ferritin at least over 70, nearer 100 better. If iron is good, can’t take iron supplements. Would need to improve ferritin just by increasing iron rich foods in diet

Stace268 profile image
Stace268 in reply toSlowDragon

I thought if Folate high enough Ferritin should be OK?

Also what's active B12, most GP only test normal B12.

Also worried about taking magnesium too regularly if affects heart, I do get sharp pain in my left foot feels like nerve pain every so often.

SlowDragon profile image
SlowDragonAdministrator in reply toStace268

Ferritin is storage form of iron

Nothing to do with B vitamins

Medichecks tests Active B12

NHS and Blue Horizon test serum B12

Magnesium is good for your heart

Modern soils are low in magnesium

So vegetables and diet is frequently low in magnesium

Magnesium best taken in the afternoon or evening, but must be four hours away from levothyroxine

My MCH has quite often been over range so now I wonder if my hypothyroidism is primary or secondary.

SlowDragon profile image
SlowDragonAdministrator in reply toStace268

That’s different K vitamin with warfarin (k1)

K2 mk7 helps direct calcium to bones to restore strength

High MCH

Low vitamins are extremely common when hypothyroid as we frequently develop low stomach acid, leads to poor nutrient absorption and low vitamin levels as direct result

healthline.com/health/mch#t...

Treatment for anemias caused by B-12 or folate deficiencies are commonly treated by lifestyle changes, such as adding foods rich in vitamin B-12 and folate to your diet. Your doctor may also recommend taking supplements of these vitamins to further boost your B-12 and folate levels

NHS only tests and treats vitamin deficiencies

Not obligated to maintain optimal vitamin levels

That’s down to us to do

NHS is not interested in managing hypothyroid patients correctly

They don’t understand the interconnected between low vitamin levels and poor conversion

Your obviously on too low a dose levothyroxine for your weight

And propranolol is badly affecting conversion and uptake of Ft4 to Ft3

Why was propranolol prescribed originally

Anxiety and I told her that I'm getting a lot of pains in my chest. Funnily low T3 can cause that.

Echo scan shows borderline Right sided hypertrophy.

My dad has heart failure.

My grandad had a stent put in after strokes.

My son has autism and multiple learning difficulties.

Hoping no connection to my health.

Anxiety is extremely common hypothyroid symptom

Also gluten intolerance extremely common with autoimmune thyroid disease (hashimoto’s)

Gluten intolerance can cause anxiety

Presumably you have Hashimoto’s

I was stuck on propranolol almost 20 years (anxiety)

Going gluten free was astonishing. Finally got off propranolol. More on my profile

If you have high thyroid antibodies (hashimoto’s) GP should test for coeliac BEFORE considering trial on strictly gluten free diet

Approx 86% of Hashimoto’s patients who try strictly gluten free diet see noticeable or significant improvement or find it’s absolutely essential

Of that 86% only 5% test positive for coeliac disease

Get your son FULL thyroid and vitamin testing via his GP, including thyroid antibodies

Make sure test is early morning around 9am

I'm not coeliac and not hashimotos as TP0 negative Again GP not interested apparently they don't treat hypothyroidism in children, sons TSH is borderline like mine.

I am trying cut out high carbs, sugar and wheat just for weight loss more than anything else. Bit like Keto diet

TPO negative
SlowDragon profile image
SlowDragonAdministrator in reply toStace268

just testing TPO antibodies is inadequate

There’s 2 antibodies implicated in Hashimoto’s

TPO and Thyroglobulin antibodies

NHS refuses to test TG antibodies if TPO antibodies are negative

Significant minority of Hashimoto’s patients only have high TG antibodies

If you test via Medichecks and both antibodies are negative

20% of Hashimoto's patients never have raised antibodies

I've been diagnosed with hypothyroidism is TG antibodies important?I had Dio2 test said I have wild type TT genotype.

I think I carry MTHR gene but scared to test it.

You won’t make progress on thyroid levels until completely off propranolol

Are you slowly reducing dose

How much are you currently taking per day

Then once all vitamins are optimal you might get T3 prescribed

I am heterozygous Dio2 (inherited from one parent)

It probably helped get T3 prescribed on NHS

But couldn’t tolerate T3 or improve vitamin levels until off propranolol and on strictly gluten free diet

I'm only on 10mg(sorry got it wrong) today was alternative day but I didn't take it.I've read beta blockers are listed as life saving drug but it I can do without it and no chest pains I'd be better off.

SlowDragon profile image
SlowDragonAdministrator in reply toStace268

so you should be able to cut quite quickly

Reduce to 5mg initially

Wait 4-6 weeks

Then reduce to 2.5mg

Then cut completely once week first week

Twice week second week

Then stop

Stace268 profile image
Stace268 in reply toSlowDragon

I may just stop as been doing alternative days a long time now

Gluten is in wheat, barley and rye

Gluten free has to be strictly gluten free to be effective

Read all labels carefully

Don’t cut all carbs ….as this reduces conversion rate of Ft4 to Ft3

Just cut beige carbs ….cakes, potatoes, rice, pasta etc

Carbs in veg and fruit are good

I was going to do Keto diet but since reading about it and Almond and Coconut flour have high omega 6 to omega 3 ratio can cause inflammation I've changed my mind.

try a normal diet, but cut gluten out completely if possible

And limit beige carbs

How high is your sons TSH

Essential to get his vitamins tested

Ask for referral to endocrinologist for him

Borderline like mine so 4.7 for instance but he symptomatic.

SlowDragonAdministrator in reply toStace268

That’s not borderline, that’s hypothyroid

Graph showing median TSH in healthy population is 1-1.5

web.archive.org/web/2004060...

If he has low vitamin levels, this tends to lower TSH

Essential to get vitamins tested and optimal by supplementing if necessary

Autistic children often picky eaters and therefore frequently have low vitamin levels

It was just above range I used mine as comparison. He had two seizures as a baby so worried about side effects of any medication.

Two separate tests with TSH over 5 and symptoms and should be started on levothyroxine

Obviously range on TSH might be different for child

yes propranolol significantly affects conversion and uptake of Ft4 (levothyroxine) to Ft3

Propranolol and thyroid hormone

pubmed.ncbi.nlm.nih.gov/168...

rejuvagencenter.com/hypothy...

labtestsonline.org.uk/tests...

Drugs that may decrease PTH include cimetidine and propranolol.

particularly important to take magnesium supplement if stuck on propranolol

It’s important to only reduce dose propranolol VERY SLOWLY

How much are you currently taking

I was stuck on propranolol almost 20 years. More on my profile

Slowdragon . i found this on "Spironolactone" ....don't know what to make of it ,or even if it matters so i'll just stick it here anyway incase it's useful anyone :

"Pituitary-thyroid function in spironolactone treated hypertensive women"

pubmed.ncbi.nlm.nih.gov/107...

"Abstract

Four weeks high dose spironolactone treatment (Aldactone Searle, 100 mg q. i. d.) significantly enhanced the TSH and T3 responses to an intravenous TRH/LH-RH bolus injection in 6 eumenorrhoeic euthyroid hypertensive women, without affecting basal serum TSH, T3 or T4 levels or the basal and stimulated LH, FSH and prolactin values .... Spironolactone, possibly by virtue of its antiandrogenic action, may exert its enhancing effect on pituitary-thyroid function by modulating the levels of receptors for TRH in the thyrotrophs or by altering the T3 receptor in the pituitary permitting a greater response to TRH."

Since being on it my sex HormoneBinding Globulin has gone under range not sure if its due to this or my age/Health. I know Spironolactone can affect potassium and kidneys as had that happen twice so I have to get adequate water intake.

I'm only on 10mg alternative days though if I feel my heart rate go up or have pain in chest I take it. Its written on script as 2 -3 times a day as required, I know it has ketamine in so can't be good unless really need it.

That’s Igennus vitamin B complex

Probably only need one per day. After breakfast

I find this is best vitamin B complex for me

I like these ones too, usually only take 1 unless really tired.

I take them 4 hrs after propranolol and Spironolactone.

How much propranolol are you currently taking

Clear guidelines on dose levothyroxine by weight

pathlabs.rlbuht.nhs.uk/tft_...

Guiding Treatment with Thyroxine: 

In the majority of patients 50-100 μg thyroxine can be used as the starting dose. Alterations in dose are achieved by using 25-50 μg increments and adequacy of the new dose can be confirmed by repeat measurement of TSH after 2-3 months. 

The majority of patients will be clinically euthyroid with a ‘normal’ TSH and having thyroxine replacement in the range 75-150 μg/day (1.6ug/Kg on average).

The recommended approach is to titrate thyroxine therapy against the TSH concentration whilst assessing clinical well-being. The target is a serum TSH within the reference range. 

……The primary target of thyroxine replacement therapy is to make the patient feel well and to achieve a serum TSH that is within the reference range. The corresponding FT4 will be within or slightly above its reference range.

The minimum period to achieve stable concentrations after a change in dose of thyroxine is two months and thyroid function tests should not normally be requested before this period has elapsed.

I have high cholesterol and spontaneous high Cortisol they suspect Cushings but I do not believe that.

SlowDragon profile image
SlowDragonAdministrator in reply toStace268

High cholesterol directly linked to still being under medicated for thyroid

Your weight suggests you need at least 125mcg - 150mcg levothyroxine per day

nhs.uk/conditions/statins/c...

If you have an underactive thyroid (hypothyroidism), treatment may be delayed until this problem is treated. This is because having an underactive thyroid can lead to an increased cholesterol level, and treating hypothyroidism may cause your cholesterol level to decrease, without the need for statins. Statins are also more likely to cause muscle damage in people with an underactive thyroid.

similarly high cortisol is extremely common when under medicated/poor conversion as adrenals try to compensate for lack of thyroid hormone

As Ft3 levels increase, cortisol levels will reduce
