Hi there, I am currently waiting my thyroid, b12 and vit d blood test results as Im having racing heart beats/palpitations, dizziness, weight loss, nausea, dermatitis, very very weak nails, fatigue.
Does anyone else have this racing heart issue with suspected or diagnosed thyroid?
I have had these symptoms for a very long time now and they have either become worse or more of them.
Many thanks 
Yes, racing or irregular heart rate common
Can see you have endometriosis.
Autoimmune thyroid disease also called Hashimoto’s and endometriosis often go together
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 iron/ferritin common with endometriosis
Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies
Ask GP to test vitamin levels and 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 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.

Wow thank you so much for all the fantastic help and information.
My gp told me not to fast and said noting about being tested early in morning. I had my test today at 9.30 am, and I had had breakfast.
My last B12 level was 183 and my Vitamin D was 50, and this was in Jan this year.
He has tested my T1 level only, and I should have the results on Monday next week.
I have decided to go for private blood tests once I have collated all my results, as I feel my B12 may be the culprit. I had a feeling that my endometriosis may also affect me in some way down the line.
What’s the Range on B12, if that’s an NHS serum test the result looks very low (range typically 200-680)
Vitamin D, are you now supplementing to improve?
Aiming for vitamin D at least around 80nmol and around 100nmol maybe better
It was on the NHS serum test and the range for my hospital said normal, 120 is considered low range.I was taking ADCAL prescribed by hospital but my GP took me off them and said just buy over counter vitamin d3, which I have been taking but I dont feel as good on them.
Serum B12 (NHS test) any result under 500 can be too low. Any result under 300 very likely too low
When were iron and ferritin levels last tested
Are you vegetarian or vegan?
How low was vitamin D
NHS Guidelines on dose vitamin D required
ouh.nhs.uk/osteoporosis/use...
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

Once you Improve level, very likely you will need on going maintenance dose to keep it there.
Test twice yearly via NHS

Vitamin D and Covid
Notice how much vitamin D many of these medics are taking
Hi, Im not vegetarian or vegan.My last blood test in March this year:
B12 183
Vitamin d level was 52
Serum Calcium 2.46 (range 2.2-2.6)
Ferritin 53ng/ml (range 15.0-300.0)
Folate 8.1 ug/l (range 2.5-9999.0)
TSH level 2.26 mu/l (range 0.3-5.0)
Free T4 10.1 pmol/l (range 7.9-16.0)
I had blood tests done yesterday and the results should be back by Monday
Hi there, I have just got my blood tests back, and the hospital have refused to re-do my b12 and folate and ferritin, and vitamin D as I have had them done already in hospital when I was admitted with a racing heart a month ago.My thyroid results are TSH level 2.31 mu/l range 0.3 -5.0, Free T4 10.6 pmol/l range 7.9-16.0 ..I feel I would like to have private tests done as I feel awful
Hi Mrss25, I had many of the symptoms you describe when under medicated. These improved massively when thyroid medication & key vitamins were optimal. Many of us test privately on this forum as then we have control over what is tested and the time etc, just post results with ranges & members will advise. I don’t even bother asking for GP comments from the blood test lab as people here are far more knowledgeable & you have to wait longer for your results if you would like a medic to comment.Best wishes to you.
Hello,I have graves disease(diagnosed 2018) which causes my thyroid to be over active.I have experienced some is the symptoms you describe.I had racing heart, increased sweating, weight loss despite increased appetite, my nails were lifting from the beds, muscle weakness and joint pain to name a few.My doctor tested T4, TSH and thyroid antibodies to diagnose.Unfortunately it's a slow process and I'm still on medication.This forum is amazing to share experiences and learn about thyroid conditions. I'm very grateful to have found it.
When I was given levothyroxine I had constant palpitations during the night in particular. The cardiologist was puzzled and was contemplating putting an implant into my heart. Just about then T3 was added to T4 and palps ceased and I never consulted with the cardiologist again.
Thyroid hormones run our whole metabolism in our bodies from head to toe. The Active thyroid hormone is T3 (liothyronine) but they prescribe T4 (levothyroxine) which is supposed to convert to T3 (it does for many people but not everyone).
You'd need to ask for a Free T4 and Free T3 to be testd.
A common problem associated with thyroid disease (and/or being female and/or some other diseases) is low iron and ferritin (iron stores).
Low iron can cause tachycardia (fast heart rate). Have you had iron, ferritin, TIBC, transferrin saturation, CRP tested recently?
I had all these symptoms except for the dermatitis and was eventually diagnosed with an underactive thyroid, hope you get sorted soon.
