Does anyone on here have normal thyroid results but they need to sleep in the day because of brain fog and/confusion? In this case, no amount of good sleep in the night seems to make a difference.

Crushing tiredness and brain fog
Welcome to the forum
Are you diagnosed as hypothyroid or trying to get diagnosed
Do you have any recent thyroid and vitamin results to add
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
Low vitamin levels are extremely common, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)
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.
In U.K. medics never call it Hashimoto’s, just autoimmune thyroid disease (and they usually ignore the autoimmune aspect)
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 and if on levothyroxine…….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

As we often say around here, normal is just an opinion… Your thyroid blood tests might have results which fall within the laboratory reference ranges but often that doesn’t mean they’re optimal.
Do you have a copy of your blood test results? If not, that’s the place to start. Ask your GP’s receptionist for a copy of them (just say you want them for your records—you’re allowed!) and then post them here for comment.
TSH 1.19
T4 9.2
Harlie2020
Please add the reference ranges (eg FT4: 15 [12-22]), your FT4 result looks suspiciously low in range. We frequently see ranges here that are 7-17, 9-19, 11-23, 12-22 and others, so we need the range that came with your results to interpret them but I would imagine your FT4 is very low in range, as will be your FT3 if it was tested, and that suggests undermedication.
We also need the ranges to respond about your results. The reason being that labs use different machines and therefore ranges can also be different.
To amend your results above, press the down arrow next to More and select edit and put in the ranges.
Are you taking a bit of T3 a few times a day?? I take 2.5mcg mid - morning, mid-day and mid - evening and find that helps a lot with the symptons you are having. This is in addition to my daily, one time, early morning dose of T4.
I’m not on any medication. I’m told I’m normal and don’t need it!
Lots of people find that helpful but others, like me, prefer to single or double dose so the cells are saturated
The problem I have is getting the medication. My doctor won’t give me any!
That’s not uncommon. You may have to source it yourself
Do you know how? Also - I’m a bit worried about self diagnosing - what if I get some levothyroxine and overdo it!
playtime2 and Hidden these replies are inappropriate
Harlie2020 is not diagnosed as hypothyroid or on any thyroid medication and TSH and Ft4 don’t suggest she has thyroid problem
My apologies for my misunderstanding SD. Her FT4 is below range. The fact that her doctor is taking the ‘normality’ of her TSH as an indicator that she doesn’t have thyroid problems doesn’t make sense. I’d appreciate some help in getting to grips with this. Thank you
Edit
We realise that a thyroid vitamin panel is an excellent test, but surely the only criteria according to NICE are TSH and FT4 (T4 if you’re lucky and FT3 if it’s your birthday.) Negatives in other tests are concerning as they will help us to get our levels optimal - but they won’t negate the criteria which a doctor should be using
Her Ft4 is NOT below range
Range is 7.7-15.1
Underlines, yet again why it’s so important to always include ranges on results.
Low vitamin levels and fluoxetine may be affecting levels too
My apologies. I didn’t look at the graph and there was no range given. I don’t think any of us would call this result ‘normal’ though SD.
That’s ‘Doctor talk’ which we try to get away from on this forum.
I hope we’re not going to fall out about 2 points 😉
Happy New Year
28% through range……not that unusual for someone not on replacement thyroid hormones
Obviously need vitamins, Ft3 and thyroid antibodies tested
Which is what Harlie2020 is doing next
SD. I’m sure Harlie is very grateful for your advice and information. I still can’t rationalise the information you’ve given to her but as long as she can that’s the main thing. 😉
I really appreciate all your contributions. I have a cortisol and thyroid peroxidase antibody test on Tuesday. vitD and ferrin good/normal. Should I have anything else?
A nice cup of tea 😉
This is my result and range
See below
These results are “normal “
Any ideas?
Low vitamin D, low B12 …..low iron/ferritin
What’s your diet like
Are you picky eater, vegetarian or vegan
Are you taking any other medications
Any other illness
My vita d was tested and good. I take supplements. I do eat well. I do drink daily although I wouldn’t say heavily. I exercise daily.
I’m taking fluoxetine as well
Harlie2020
I’m taking fluoxetine as well
I do drink daily although I wouldn’t say heavily
Are you aware that drinking alchohol is not recommended when taking fluoxetine and this may be causing your fatigue and brain fog/confusion. See
healthline.com/health/depre... alcohol
Interactions
The ingredients in Prozac are designed to help calm your mood. One of the side effects of the drug is tiredness. Prozac can interfere with coordinated movement and alertness, like alcohol does. Combining Prozac with alcohol can quickly lead to increased sedation. Having even one drink while you take Prozac can cause extreme drowsiness. This effect can lead to potentially dangerous situations. These include poor decision-making, impaired driving, and an increased risk of falls and injuries.
Mixing alcohol and Prozac can also lead to other side effects. These can include:
dizziness
sudden fatigue and weakness
feelings of hopelessness
suicidal thoughts
Mixing Prozac and alcohol may cause fatigue and weakness.............
So maybe, before going to the expense of private testing of all that has been suggested and the cost of seeing an endo privately, you could stop the alcohol whilst taking fluoxetine and see if things improve.
A TSH of 1-1.5 is absolutely “normal “

Suggest you test thyroid, cortisol, vitamin D, folate, ferritin and B12 via Blue Horizon
When you say test thyroid. What do you mean?
Just testing TSH and Ft4 is incomplete
Full thyroid testing is TSH, Ft4 and Ft3 plus BOTH TPO and TG antibodies
Your TSH and Ft4 don’t suggest a problem
But you might have raised thyroid antibodies
Low vitamins can make you feel very unwell, especially low iron/ferritin
Anxiety can affect cortisol levels
Cheapest way to test vitamin D, folate, ferritin B12 and cortisol levels is by testing along with thyroid Via Blue horizon

But the FT4 isn't! Since when did you condone diagnosing and dosing by the TSH?
Ft4 is 28% through range
Yes? And you think that's normal??? Pretty certain is isn't. There was a time when you wouldn't have thought that, either. What happened? And, if her FT4 is that low, could be that her FT3 is lower - and if it's higher, then that's pretty conclusive proof that her thyroid is struggling.
Thanks for the comments.
I am due to have a cortisol and thyroid peroxidase antibody test on Tuesday. vitD and ferrin good/normal. Should I have anything else?
What do you call good/normal? Whose opinion is that? If it's your doctors then he could be wrong - they very often are. Always best to give the exact numbers: results and ranges. 'Good/normal' is meaningless.
Is it your doctor doing these tests on Tuesday? Because, if it is, he won't be aware that there are two Hashi's antibodies: TPOab and TgAB. Ideally, you want them both tested, because the TPOab can be low, and your TgAB could be high, and both mean that you have Hashi's.
You also need vit B12 and folate. tested.
Is TGab the one that they are not testing for? The form says thyroid peroxdaise antibody - what do I need to add? B12 and folate too
These are my other results
Ferritin is not deficient….but it’s still pretty poor
Was obviously very low/deficient in past tests
Have you been working on improving low iron/ferritin
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

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.

Chicken livers if iron is good, but ferritin low

Oh, I hate those stupid graphs! Can never make head nor tail of them! Can't even see them clearly on here.
Much prefer that information is given in the following way:
Date:
Name of test: result (range).
That way, we can see all the important info at a glance.
So vitamin D is pretty good
Do you supplement?
Yes
Hi Harlie2020,
SlowDragon makes a very good point about the term ‘normal’ (note my use of the inverted commas). It is a misused term that you should be wary of. What should be aimed for is OPTIMAL.
Only two little words, but they mean very different things. In fact one could say ‘normal’ is meaningless. GPs who don’t know what they are doing generally tell you that you are ‘normal’ if you are in range.
The trouble is the majority of GPs don’t understand what the range is there for - it’s a guide only! Sadly most think the range is a ‘cup’ and that the patient is a ‘ping-pong ball’ and if they get the ping-pong ball in the cup they win a prize.
They simply do not understand that you can be on completely different doses at either end of the range and be hypo (at the lower end) and be optimal and well (at the upper end) OR, heaven forbid, because of other confounding factors you may sit outside the top of the range before you feel well OR (panic stations) the range might not apply at all! 😱😂.
Symptoms should be the most important diagnostic tool, but it sits at the bottom of the list as an annoyance. Nothing annoys a doctor more than having a lovely set of blood results, all ‘normal’ and the damned patient goes and spoils it all by having symptoms! 😂
Ever been told by a GP “Your symptoms should have cleared up by now” or something similar and made to feel the failure for not having responded to their rubbish treatment??
Vitamins need to be higher than just in the bottom of the range SlowDragon has provided loads of info on this - work through it - it is worth it. GPs in the main have no idea on this either - refer back to cup/ping-ping ball scenario.
If you take the advice from seasidesuzie and drop alcohol
Then get vitamins and thyroid checked as advised by SlowDragon you will have a better idea of what is going on. And get PRINTED results don’t rely on Patient Access- my Patient Access is patchy and things have been altered/disappeared (yes really). I have screenshots 🤔. I also have my complete set of tests- get copies of everything keep records 😊👍.
Sometimes other medication and lifestyle can suppress TSH and it’s not even a direct measure of something your thyroid makes.. TSH is a really unreliable measure in isolation and adds very little to diagnosis or management compared to getting FT4 and FT3 results and getting your vitamins optimal (not normal).
The forum came to my rescue about a year ago. I’m well and here as a result of their support and advice.
There’s lots to get your head around but plod through it at your own pace - it is worth the effort (from one who has been plodding my way through too and in a better place as a result).
Thank you. That is really helpful. I agree optimal should be the aim. It is so frustrating to be told - I’m not sure we can do anything for you when they haven’t done the right tests and/ or read the result correctly. The impact on my life is no joke and yet I’m getting ‘computer says no!’. Sooooo frustrating. Thanks again x
Please add actual results and ranges for vitamin D and ferritin
We regularly see what a GP says are “normal” vitamin results….that are far from OPTIMAL
Optimal vitamin levels are
Vitamin D at least around 80nmol and around 100nmol maybe better
Serum B12 at least over 500
Folate and ferritin at least half way through range
Extraordinary how often a GP will say ferritin is normal when it’s under 30
cks.nice.org.uk/topics/anae...
In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency
There are two thyroid antibodies for autoimmune thyroid disease
TPO and TG antibodies. NHS only tests TG antibodies if TPO antibodies are high. Significant minority of Hashimoto’s patients only have high TG antibodies and struggle to get diagnosed
Which is why I suggest that she gets FULL thyroid and vitamin and cortisol testing
I agree it’s on low side….but there’s zero point taking these results to an endocrinologist
I have a friend, similar results….stuck on SSRI antidepressant over 35 years….low energy etc. A year ago they got FULL thyroid and vitamin testing done via BH - showed deficient folate, very low vitamin D, low B12….lowish Ft4 and lowish Ft3….but no raised antibodies.
After 9 months improving all four vitamins to GOOD levels was able to successfully ween off SSRI with very little difficulty …..subsequent full thyroid testing 3 months later now shows excellent Ft4 and Ft3
Another friend…..has lichen planus…..and an impeccable diet. She had full thyroid and vitamin testing done…..was utterly astonished to see low folate, very low vitamin D, only average B12 and ferritin. Lowish Ft4 and Ft3…..but no raised thyroid antibodies. Improving low vitamin levels by supplementing significantly improved thyroid levels. As lichen Planus is autoimmune she has gone strictly gluten free and seen dramatic improvement in lichen symptoms
I agree it’s on low side….but there’s zero point taking these results to an endocrinologist
Agreed. But there's zero point in telling the OP that her results are 'normal', either.
Her ferritin was dire/deficient…..now improving ….but still got long way to go to optimal
Be interesting to see what B12 and folate are
Yes. But so has her FT4!
Ft4 is 9.2 (7.7-15.1)
That’s 28% through range
Yes, so you have pointed out several time, and I have seen for myself, and I still say that is NOT normal.
SD,
TSH - 1.19
FT4 - 9.2 [7.7 -15.1]
Even without ranges TSH appears too low with FT4 of only 20% through range (not 28% 😉), for someone unmedicated.
I would not call this 'normal' either. Even with the likely iron/nutrient deficiencies, TSH should be higher encouraging wholly inadequate FT4 levels to raise, and based on these results & O/P's symptoms FT3 is likely to be inadequate also.
Wishing you all a Happy New Year, bursting with fulfilling and exciting opportunities. And remember, if opportunity doesn't knock, build a door! 😂😂😂😂
😅🤣😂 love that.....I think a lot of us are quite good at building doors thankfully! Happy New Year to you! Xx

I’ve just been looking at your question, Harlie, the question which started this thread.
The symptoms you’ve described can be associated with very many conditions. I’ve said on here before that we just rule anything out or anything in, you should have a thorough investigation which should go beyond blood tests.
There are many members on the HU forums who would confirm that their final diagnosis was far from that they first considered. Menopause, Diabetes etc.
