Normal TSH and T4, but no endorphin rush when exercising and fatigued all of the time.

Hello all

I would appreciate some advice about what to do next. I have a diagnosis of lupus and am taking methotrexate prescribed by my rheumatologist. I am pretty certain that I have hypothyroidism. I feel so very tired all of the time, so cold, my muscles and joints are painful, I have a perpetually sore mouth with ulcers and feel that all of my systems are on a go slow. I have mild constipation, very dry skin and hair and my hair is extremely short as it now falls out before it gets a chance to grow to any length. I do not have bald spots, but my hair looks as though I have randomly hacked at it.

My metabolism is not behaving at all. Over the past 2 years I inexplicably gained almost four stone. I managed to lose two stone during the past year by exercising daily and maintaining an ultra sensible diet i.e. no alcohol, very little junk food, or sweet food, however I still weight two stones more than I should and cannot seem to lose any more. I used to run daily and have resumed running during the past year, however I find that when I try to jog on the treadmill I just can't seem to keep going. The best way of explaining it is this. If I were battery operated, my battery would be in need of changing. I just cannot get that endorphin rush that keeps you going when you exercise. The same thing happens when I do other exercise.

I do have a tendency towards iron deficiency and have had two iron infusions, most recently in May this year. My Gastroenterologist cannot find any particular source of bleeding and thinks I have either unexplained bleed, or anaemia of chronic illness.

My bloods are all within normal ranges right now.

TSH - 2.44

T4 - 13.1

Haemoglobin - 140

Ferritin 500 - due to iron infusion during summer

Transferrin - 2.20

Iron - 18

Transferrin saturation - 33

CRP - Less than 1

ESR - 2

B12 - 312

Folate 18.6

Serum cortisol - 374

Vitamin D - 100

Despite all of the normal results, I feel so exhausted all of the time. My rheumatologist and gastroenterologist think that this fatigue is lupus related, as most people with lupus experience chronic fatigue.

I cannot help feeling that my thyroid is playing up. I say this because of the difficulty losing weight, mild constipation and other symptoms described above.

Any thoughts anyone?

Can you add test ranges to your results please? They vary from lab to lab and hard to tell without them. Also, there is no FT3 reult, NHS rarely tests this, hence many of us paying privately to get what we need.

Have you ever had thyroid antibodies tested? That would also give a clue.

Hi Jaydee 1507

These are some of the ranges, but I can confirm that my results tend to fall in the middle of all ranges used, so they seem normal. I did have antibodies tested and the results were negative, but that was a couple of years ago.

Vit B12 range is 200 - 883 ng/L

Folate range is 3.1 - 20.0 ug/l

TSH range is 0.35 - 5.00 U mU/L

T4 range is 9.0 - 21.0 U pmol / L

If you're taking a B complex then your B12 is too low. Are you vegetarian/vegan?

Your FT4 is on the low side but your TSH isn't high enough to get a diagnosis.

You could try and get thyroid antibodies tested? If positive would indicate an issue.

Thanks Jaydee1507

Just googled Methotrexate and it can cause tiredness and fatigue as well as hair loss. Also doctors can prescribe folic acid which mitigates some of the effects of the drug, are you taking that? It could be thyroid related as autoimmune conditions often go together, but it could also be the Lupus or the Methotrexate.

Hi there Sparlingsunshine

I don't really think it's the methotrexate as I stopped taking it some time ago (due to lack of effect) and I'm still having the same symptoms. I was taking the folic acid when i was taking the methotrexate but I've stopped taking that too, though I do take vitamin B complex soluble twice weekly together with other supplements.

Lupus and Hashimoto’s frequently go together

Was test done early morning for highest TSH

What’s the range on Ft4 result, folate, B12

B12 looks low ….and Ft4

What vitamin supplements are you currently taking

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

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. 

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)

20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis 

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 just before 9am

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

Medichecks Thyroid plus antibodies and vitamins

Blue Horizon Thyroid Premium Gold includes antibodies, cortisol and vitamins

Only do private testing early Monday or Tuesday morning. 

Watch out for postal strikes, probably want to pay for guaranteed 24 hours delivery

Hello SlowDragon

My bloods were taken at 8am before eating. The supplements I am taking are selenium, kelp, zinc, fish oil capsules, L Lysine and stexerol vitamin D 1000 units per day, plus soluble vitamin c and B complex on Saturday and Sundays.

Vit B12 range is 200 - 883 ng/L

Folate range is 3.1 - 20.0 ug/l

TSH range is 0.35 - 5.00 U mU/L

T4 range is 9.0 - 21.0 U pmol / L

What are your thoughts?

Really not a good idea to supplement kelp or iodine in any form with possible thyroid disease, especially possible Hashimoto’s

Suggest you stop taking this and retest thyroid in 2-3 months

Iodine can make thyroid disease 10 x worse

Unless a long term vegan, unlikely low in iodine

Genova Diagnostics for iodine test

thyroiduk.org/help-and-supp...

Click on "Read the list of available tests" and on page 3 of the pdf you'll see

Urine Iodine Test:

Specimen requirements: Urine

Cost: £71.00

Order Code: END25

Turnaround time: 5 - 10 days

Iodine is an essential trace element, vital for healthy thyroid function. Adequate levels are required to enable the production of T3 and T4 thyroid hormones, whilst also being required in other areas of health.

Deficiencies can lead to impaired heat and energy production, mental function and slow metabolism. Urine iodine is one of the best measures of iodine status. This test is not performed as a loading test, but can be used to establish existing levels or to monitor iodine supplementation.

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

Which B complex are you currently taking

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

 

B12 is too low

Do you have Low B12 symptoms 

b12deficiency.info/signs-an...

methyl-life.com/blogs/defic...

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.

B12 drops 

healthunlocked.com/thyroidu...

B12 sublingual lozenges 

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

cytoplan.co.uk/shop-by-prod...

B12 range in U.K. is too wide

Interesting that in this research B12 below 400 is considered inadequate 

healthunlocked.com/thyroidu...

suggest you improve B12, stop taking kelp and get FULL thyroid test including thyroid antibodies in 2 months time

Do any private Test early Monday or Tuesday morning

Medichecks or Blue horizon offer test including both TPO and TG antibodies

Hi SlowDragon - Many thanks for this. I will do as suggested . Happy Christmas :)

Just a quick point on iron deficiency: it is common in people who have chronic kidney disease.

Have you had your kidney function checked?
