Marginally high TSH

Duckeggs profile image
8 Replies

hi everyone,

I did a blood test back in late August for various symptoms such as high heart rate, nausea, lightheaded, heart palpitations, as well as chest pain. I was sure it was hyperthyroidism, as I have history of this back in 2018. I also have history of hypothyroidism in 2021 during pregnancy only with zero symptoms.

My blood test for thyroid shows TSH at 4.75 mU/L and t4 is 14pmol/L. My GP didn’t test t3 or antibodies. He said he will order a retest in 3-6 months. Another GP ordered a 24 hour ecg that showed tachycardia and some sinus tachycardia, in an otherwise healthy heart. Referral to a cardiologist upon my request.

I don’t know what to make of this as my symptoms showed hyperthyroidism however my blood test showed as subclinical hypothyroidism. I am so confused. My symptoms have been debilitating and I am experience near fainting episodes and have fainted once. The random high heart rate really affects me. My vitamin levels are all within normal range but on the lower end of normal for vitamin D, ferritin is at 37 and folic acid at 6.9. B12 is on the higher end.

Any insight would be appreciated

So next step is to improve low vitamin levels

Then get FULL thyroid and vitamin testing

ALWAYS test thyroid levels early morning

How low was vitamin D

How much vitamin D are you taking

NHS Guidelines on dose vitamin D required

panmerseyapc.nhs.uk/media/2...

GP will often only prescribe to bring vitamin D 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 if over 50nmol, but under 75nmol (but they rarely do)

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

But improving to around 80nmol or 100nmol by self supplementing may be better

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

vitamindsociety.org/pdf/Vit...

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

Test twice yearly when supplementing

Can test via NHS private testing service

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.

One spray = 1000iu

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

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

Vitamin D may prevent Autoimmune disease

newscientist.com/article/23...

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

only add one supplement at a time and then wait 10-14 days to assess before adding another

Suggest starting with vitamin D

Low folate

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

This can help keep all B vitamins in balance

Difference between folate and folic acid

healthline.com/nutrition/fo...

Many thyroid patients have MTHFR gene variation and can have trouble processing folic acid supplements

thyroidpharmacist.com/artic...

B vitamins best taken after breakfast

Igennus B complex popular option. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose and may need separate methyl folate couple times a week

Post discussing different B complex

healthunlocked.com/thyroidu...

Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) Thorne can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

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

endocrinenews.endocrine.org...

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg)

High B12, if not supplementing, especially with low folate …..could be paradoxical B12

Paradoxical B12 deficiency

Hi, thanks for getting back. I don’t know what to make of the mismatched symptoms and wondering if anyone else experienced my symptoms with hypothyroidism?

In response to your questions. My vitamin d level was at 50. So I think it’s literally on the border. I started supplementing with 2,000 iu in the past two weeks on my own.

Everything else seems fine with my vitamin levels so I’ve not been supplementing.

GP didn’t prescribe any levothyroxine for the sibclinical hypothyroidism. Is that something I should request?

Low vitamin levels common when thyroid levels are low

Then retest thyroid including thyroid antibodies

Low ferritin

cks.nice.org.uk/topics/anae...

Serum ferritin level is the biochemical test, which most reliably correlates with relative total body iron stores. In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency

Never supplement iron without doing full iron panel test for anaemia first and retest 3-4 times a year if self supplementing.

It’s possible to have low ferritin but high iron

Test early morning, only water to drink between waking and test. Avoid high iron rich dinner night before test

If taking any iron supplements stop 5-7 days before testing

Medichecks iron panel test

medichecks.com/products/iro...

Look at increasing iron rich foods in diet

Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

List of iron rich foods

dailyiron.net

davidg170.sg-host.com/wp-co...

Great in-depth article on low ferritin

oatext.com/iron-deficiency-...

drhedberg.com/ferritin-hypo...

This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.

Get FULL thyroid and vitamin retest 6-8 weeks after adding last vitamin supplement

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test

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

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

Post all about what time of day to test

healthunlocked.com/thyroidu...

Testing options and includes money off codes for private testing

thyroiduk.org/testing/

Medichecks Thyroid plus BOTH TPO and TG antibodies and vitamins

medichecks.com/products/adv...

Medichecks and BH also offer private blood draw at clinic near you, or private nurse to your own home…..for an extra fee

Only do private testing early Monday or Tuesday morning.

Do you have the ranges for your blood test results? You could put them into the thyroid calculator I wrote, at thyroid.chingkerrs.online/ and see the percentage through ranges (the ranges vary by lab so percentages are often more meaningful).

Thanks, I can give this a try. How does this work exactly? What does the calculator show after?

Decant in reply toDuckeggs

Hopefully it's quite self explanatory and it has a little bit of help information on the page. You basically type the blood test and minimum and maximum values from the range and it displays the percentage through the range. Then you press the "Copy Results" button and paste the text into your post here on HealthUnlocked. There are rows for the common thyroid and vitamins that the admins here like. Have a go!

I'd be happy to hear if you have any feedback on how I could make it easier to use!
