Underactive Thyroid?

Hi all,

I've posted previously about my symptoms and suspicions of having an underactive thyroid.

Just for a quick recap the below was my recent NHS blood results;

May 2020 T4 = 11.9 (range 12-20)

May 2020 TSH = 1.89 (range 0.27-4.20)

November 2020 T4 = 12.3 (range 12-20)

November 2020 TSH = 1.89 (range 0.27-4.20)

November 2020 Thyroid Peroxidase Antibodies = 274 (range 0-34)

December 2020 B12 = 163 (range 197 - 771)

I am going in today for another blood test to rule out rheumatoid arthritis as I already have an autoimmune condition (type 1).

My symptoms are getting worse by the day, to the point that I've gone from being very active to needing assistance doing something as simple as changing my bed sheets.

I've also developed left sided neck pain recently, but I don't think that has any link with the thyroid because of where the pain is located.

I have been prescribed vitamin D and B12 for the deficiencies and my GP wants my vitamin levels up before we take it any further. I have also gone completely gluten free starting last week.

He doesn't seem concerned about the high antibodies as my TSH is within normal range.

I understand I have autoimmune thyroid disease due to these antibodies, but is there no treatment unless my TSH rises?.

Thank you

Clearly you need treatment, as Ft4 is below range

But this is beyond GP

Have you had prolactin tested?

You need thyroid specialist endocrinologist

How low was vitamin D

How much vitamin D are you currently taking

How low B12

Did you get tested for Pernicious Anaemia

Are you taking B12 supplements or getting B12 injections

You need folate and ferritin levels tested too

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially as you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Is this how you do your tests?

Private tests are available as NHS currently rarely tests Ft3 or thyroid antibodies or all relevant vitamins

If you can get GP to test vitamins and antibodies then cheapest option for just TSH, FT4 and FT3

£29 (via NHS private service ) and 10% off down to £26.10 if go on thyroid uk for code

If TPO or TG thyroid antibodies are high this is usually due to Hashimoto’s (commonly known in UK as autoimmune thyroid disease).

About 90% of all primary hypothyroidism in Uk is due to Hashimoto’s. Low vitamin levels are particularly common with Hashimoto’s. Gluten intolerance is often a hidden issue to.

Vitamin D was - 25.5 (Range 50-175) and I was prescribed Colecalciferol 800U and Cyanocobalamin for the B12.

Folate and ferritin levels were within normal range as I was told over the phone but I didn't get the numbers.

See/contact GP

Vitamin D is deficient

Guidelines are quite clear you should be prescribed 300,000iu over 6-8 weeks

That’s 5000iu per day over 8 weeks or 7000iu over 6 weeks

800iu isn’t enough for a well mouse

NHS Guidelines on dose vitamin D required

ouh.nhs.uk/osteoporosis/use...

Vitamin D

GP will often only prescribe to bring levels to 50nmol.

Some areas will prescribe to bring levels to 75nmol or even 80nmol

leedsformulary.nhs.uk/docs/...

GP should advise on self supplementing once levels over 50nmol, but under 75nmol (but they rarely do)

mm.wirral.nhs.uk/document_u...

But with Hashimoto’s, improving to around 80nmol or 100nmol by self supplementing may be better

ncbi.nlm.nih.gov/pubmed/218...

vitamindsociety.org/pdf/Vit...

Once you Improve level, you will need on going maintenance dose to keep it there.

Test twice yearly via vitamindtest.org.uk

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

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

It’s trial and error what dose we need, with hashimoto’s we frequently need higher dose than average

Calculator for working out dose you may need to bring level to 40ng/ml = 100nmol

Government recommends everyone supplement October to April

Taking too much vitamin D is not a good idea

chriskresser.com/vitamin-d-...

Web links about taking important cofactors - magnesium and Vit K2-MK7

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

Vitamin K2 mk7

betterbones.com/bone-nutrit...

healthline.com/nutrition/vi...

pubmed.ncbi.nlm.nih.gov/286...

Vitamin D deficiency is frequent in Hashimoto's thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

pubmed.ncbi.nlm.nih.gov/300...

The thyroid hormone status would play a role in the maintenance of vitamin D sufficiency, and its immunomodulatory role would influence the presence of autoimmune thyroid disease. The positive correlation between free T4 and vitamin D concentrations suggests that adequate levothyroxine replacement in HT would be an essential factor in maintaining vitamin D at sufficient levels.

You are legally entitled to printed copies of your blood test results and ranges.

The best way to get access to current and historic blood test results is to register for online access to your medical record and blood test results

UK GP practices are supposed to offer everyone online access for blood test results. Ring and ask if this is available and apply to do so if possible, if it is you may need "enhanced access" to see blood results.

Link re access

healthunlocked.com/thyroidu...

In reality many GP surgeries do not have blood test results online yet

Alternatively ring receptionist and request printed copies of results. Allow couple of days and then go and pick up.

Important to see exactly what has been tested and equally important what hasn’t been tested yet

Come back with new post once you get actual results and ranges on folate, ferritin and B12

supplementing a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.

This can help keep all B vitamins in balance and will help improve B12 levels too

Difference between folate and folic acid

chriskresser.com/folate-vs-...

Many Hashimoto’s patients have MTHFR gene variation and can have trouble processing folic acid.

thyroidpharmacist.com/artic...

B vitamins best taken after breakfast

Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)

Or Thorne Basic B is another option that contain folate, but is large capsule

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

endo.confex.com/endo/2016en...

endocrinenews.endocrine.org...

Low B12 symptoms

b12deficiency.info/signs-an...

With low B12 result taking a B12 supplement as well as a B Complex (to balance all the B vitamins) initially for first 2-4 months, then once your serum B12 is over 500 (or Active B12 level has reached 70), stop the B12 and just carry on with the B Complex.

B12 sublingual lozenges

amazon.co.uk/Jarrow-Methylc...

cytoplan.co.uk/vitamins/vit...

Only add one supplement at a time and then wait at least 10 days to assess before adding another

Studies are showing that low vitamin D is linked to severity of COVID.

Samanthamcx in reply to penny

Yes, I'd read that - as far as I'm aware I haven't had Covid (unless I've been asymptomatic)

penny in reply to Samanthamcx

Even if you haven’t had it it doesn’t mean to say that you won’t. Hopefully you’ll miss it, although being asymptomatic may confer some immunity. Having higher levels of vitamin D not only lessen severity they are also cited as being helpful in preventing certain cancers.

Samanthamcx in reply to penny

Of course not, there's always a risk and I only leave the house for food or blood tests since I work from home. I'm now on vitamin D and B12 medication.

Hopefully after the advice from SlowDragon you’ll be looking at taking more than 800iu of vitamin D3. Good luck.
