blood tests say over medicated on levo but feel awful without it

hello

I was diagnosed with hypo 18 months ago (TSH 48) and put on 50 levo then told that was too high and went on 25mg. Felt AWFUL on 25mg rapidly gained weight, fatigue , pins and needles, depression etc. but now have convinced my endo to let me have 37mg my blood work shows my TSH is now 0.01

free t4 is 23 and free t3 is 7.7 so worried they will take my off meds completely. Even though my ultrasound my thyroid is nearly atrophied and very high thyroid antibodies.

Has anyone else found this? I am so confused and endo seems equally confused.

My white blood cell count has also been flagged as high. Be great if anyone can shed any light on any of this!

Thank you so much

Hi Frankyn, welcome to the forum.

If you have very high antibodies, and a shrunken thyroid, then you have Ord's Thyroiditis. Not surprised your endo is confused! lol He doesn't have the training to know what's going on.

Ord's disease is the same as Hashimoto's Thyroiditis except that with Ord's the thyroid shrinks, and with Hashi's, there's usualy a swollen thyroid - a goitre. Have you heard of Hashi's? It's more well-known than Ord's.

They are both autoimmune diseases - hence the antibodies - where your immune system slowly destroys your thyroid. And, during an attack on the thyroid, the dying cells deposit their stock of hormone into the blood, causing your FT4/3 to rise sharply, and the TSH therefore becomes suppressed.

So, you're not over-medicated, you're having a temporary 'hyper' swing. Eventually the excess hormone will be used up/excreted, and you will become hypo again. It's crazy that endos don't know about this, but they don't. You'll have to explain it to him. :)

Thank you so much for taking the time to reply. Ever since I started levo my TSH has consistently been under 0.3 is that standard for Ord’s? Thank you again

Nothing is standard for Ord's. Everything varies all the time. :)

But, what time do you have your blood draw? TSH is highest early morning - before 9 am. It then drops sharply until it is at its lowest around midday. So, given that most doctors only look at the TSH, we always advise getting the blood draw before 9 am. That way, you can compare them more accurately.

One more thing, how long was the gap between your last dose of levo and the blood draw? If you took it a couple of hours before, you have a false high FT4. You need to leave a gap of 24 hours.

But, you still have Ord's. :)

That’s a very small dose of levothyroxine

Just testing TSH is completely inadequate

ALWAYS test thyroid levels early morning, ideally before 9am and last dose levothyroxine 24 hours before test

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

For full Thyroid evaluation you need TSH, FT4 and FT3 tested

plus both TPO and TG thyroid antibodies tested at least once

Very important to test vitamin D, folate, ferritin and B12 at least once year minimum

About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies

Autoimmune thyroid disease with goitre is Hashimoto’s

Autoimmune thyroid disease without goitre is Ord’s thyroiditis, where thyroid shrinks and shrivels up

Ord’s is very common in U.K.

Both are autoimmune and generally called Hashimoto’s.

Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)

Have you had vitamin D, folate, ferritin and B12 levels tested

Are you currently taking any vitamin supplements

In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)

Recommended on here that all thyroid blood tests early morning, ideally before 9am and last dose levothyroxine 24 hours before 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 or all relevant vitamins

Have you had coeliac blood test done

Extremely common to develop Gluten intolerance with any autoimmune disease, but especially with autoimmune thyroid

Only 5% of Hashimoto’s patients are diagnosed as coeliac, but a further 80% find strictly gluten free diet helps or is essential

Did you have fT3 or fT4 measured when your TSH was 48? This would be useful as there is a genetic condition called resistance to thyroid hormone (RTH) which presents with a high fT3 or fT4 and a non-suppressed TSH This puts high demand on the thyroid and makes it susceptible to autoimmune thyroiditis.

What were your blood test results when you were on 25 mcg?

Frankyn in reply tojimh111

Thank you I’ve never heard of this! Bloods were TSH 0.03 free t3 4.2 abs free t4 12.8

Please add ranges on these Ft4 and Ft3 results

Different labs have different ranges

jimh111 profile image
jimh111 in reply toFrankyn

In that case it will not be RTH.

Gosh thanks so much for the replies l. So so helpful these last tests were at 9.00 and 25 hours after a dose but previous ones weren’t.

This time my ferritin is 67 but white blood cells and neutrophils been flagged as low.

For my last blood tests in February (on 25mg levo) and my TSH was still 0.01 and free T4 was 21. My iron saturation was also flagged as low (14) and triglycerides as high (2.46)

My anti TPO was 345 and ANTI TG was 179

The consultant says he doesn’t understand why when my TSH was 48 before meds and antibodies are so high the bloods show that even 25mg is too high for my body. I am keen to try a different medication…

Thanks again. It’s all so new and confusing to me x

So home many blood tests have shown high Ft4 and Ft3 and low TSH

A temporary hashi flare can last a few months

A Hashimoto’s flare is when thyroid hormones are released as cells in thyroid breakdown after an immune attack

After each attack thyroid becomes a little more damaged and increasingly hypothyroid

These flares tend to only happen in early stage of the disease. Eventually the Thyroid becomes completely defunct

Have you had vitamin D, folate and B12

What vitamin supplements are you currently taking

Biotin can falsely affect test results, biotin is in many vitamin supplements

Low vitamin levels tend to lower TSH

Get GP to retest thyroid levels every 2-3 Months

If not had test since February that’s far too long a gap

You should have bloods retested 6-8 weeks after each dose change or brand change in levothyroxine

When was dose increased to 37.5mcg ?

Which brand of levothyroxine are you currently taking

Many people find different brands are not interchangeable

Request coeliac blood test and vitamin testing

Frankyn in reply toSlowDragon

Thank you I will def request these tests. I did have a test on march when on 25mg and my TSH was 0.03 free t3 was 4.2 and free T4 was 12.8 so more in line with what the doctors wanted but that’s when I felt my worse

Definitely feel like I’ve had a flare up as felt worse this year than before I was diagnosed. My symptoms before diagnosis were weight gain, puffiness, cold , flu like, pale etc and now rapid weight gain, pins and needles all the time, sore throat every day, horse voice, fatigue etc.

I know I’m not alone and everyone here suffers with different symptoms .

Does anyone Else alway get low white blood cell counts?

Thanks again

TSH was 0.03

free t3 was 4.2

free T4 was 12.8

Please add ranges on these (figures in brackets after each result)

Ft4 and Ft3 look extremely low (under medicated)

ESSENTIAL to test folate, ferritin and B12 at least annually, more frequently if levels are low and working on improving

B12 is normal”

Please add actual result

Medics will say anything within range is normal

Range on B12 is typically 180-680

On levothyroxine we need B12 at least over 500

Test vitamin D twice year when supplementing

Exactly what “thyroid supplement” are you taking

Never take anything with iodine in, especially with Hashimoto’s

Never take iron supplements without testing full iron panel test first

Iron supplements must be be minimum 4 hours away from levothyroxine

Frankyn profile image
Frankyn in reply toSlowDragon

Thanks so much B12 was 331

Ferritin is 67

I am not consistent with my vitamins at the moment take zinc some days and b6 or b12 or a combined supplement others

Will check if iodine is in there now

SlowDragon profile image
SlowDragonAdministrator in reply toFrankyn

Basically avoid anything labelled a “thyroid supplement”

Most contain iodine or kelp in some form

B12 too low

No folate result?

Ferritin ok….over 70 is better

If taking iron supplement extremely important to do full iron panel test 3-4 times a year

It’s possible to have high iron and low ferritin

Iron is extremely toxic in excess

Low B12supplementing a good quality daily vitamin B complex, one with folate in (not folic acid)

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

Thorne Basic B recommended option that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule)

IMPORTANT......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...

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement and continue separate B12

Low B12 symptoms

b12deficiency.info/signs-an...

With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a B12 supplement as well as a B Complex (to balance all the B vitamins) initially for first 2-4 months.

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.

Was it just 1 high TSH without FT4 & FT3 results ?

The TSH of 48 could have been a false result? Antibody or biotin interference for example. Do you have FT4 & FT3 to compare?

Frankyn profile image
Frankyn in reply toPurpleNails

Yes just one high TSH result but my symptoms, the antibodies and ultrasound confirmed the hashimotos. I don’t have the t3 or 4 from those results annoyingly.

In march when I went down to 25 every day my TSH was 0.03 and free T3 4.2 and free T4 12.8 so the doctors would rather I was on that but feel so much better on 37.

Have put Ona stone and a half since they made me go down to 25mg.

My B12 was normal but haven’t had other virnamon checks will ask for them! And I take a thyroid supplement, iron tablets and zinc that now sounds is t the best thing to take.

Creatine and white blood cell count slightly low on all my results . Hard to know what’s best to ask for to feel better

PurpleNails profile image
PurpleNailsAdministrator in reply toFrankyn

Which thyroid supplement do you take?

Selenium & zinc are safe supplements but many thyroid support preparations contain iodine which might not be good and can affect thyroid adversely (& unpredictable). Causing either a decrease in levels or increase in levels.

Iron shouldn’t be taken unless iron panel done & known deficient.

I’ve noticed others with similarly elevated levels and not sky high levels tend to gain weight. I think it’s a result of low energy / high appetite,

Once levels are very high most are unwell & lose weight. I had unnoticed elevated levels many years.

You may also feel worse when changing dose not because it’s too high or too low a dose you may be like me and be quite sensitive to alterations & fluctuations which occur more often with autoimmune under active thyroid.

Your FT4 & FT3 levels were too low on 25mcg. The doctors are focusing on TSH. Aim for small increases (every 6 weeks) until FT4 in top third of range.

Yes, my sister has the same problem. The slightest reduction of levothyroxine and she feels awful. Fortunately she has educated her doctor to accept this situation. She also stopped taking the levothyroxine 24 hours before the test. She has been like this for quite a few years now without any problem.
