She’s not taken her thyroxine ( she takes 100 of levo a day since birth of her previous child 5 years ago) she stops the levo for a day if her heart too racy but this hasnt worked.

100mcg is quite a low dose, my Dad is on that because he is classed as elderly at 78. Do you have any of her blood results to share with us? We need TSH, T4, T3 and antibodies. Also has she had her vitamin levels checked because they are always low with people who have thyroid disease. We need B12, Iron and Ferritin, Vitamin D and Folate. I am sorry for your daughter's loss btw.

I’ve put her recent test results on here and she’s been fine until the anaesthetic. I’m on 100 and sos her sister too. Can’t get tested again for a bit just wondered if anyone had similar reaction?

100mcg is a low dose imho how do you feel? My Dad is fine on that dose but he is classed as elderly. Your TSH should be 1 or lower and your T4 and T3 should be in the upper third of the range.

Perhaps your daughter/s should join this site and so avoid the confusion? Do they have a computer?

Also I am glad you feel well on that low dose my Dad feels ok as well but he did have a strange result a couple of months ago when his TSH jumped up to 20 so his GP is keeping an eye on him

Sorry for your daughter’s miscarriage

Miscarriage often linked to being under treated for hypothyroidism. Was her dose of levothyroxine increased once pregnancy was confirmed

See pages 7&8

btf-thyroid.org/Handlers/Do...

Racing heart can be due to being under treated. Especially low Ft3

Anaesthetic can significantly affect B12 levels

b12-vitamin.com/anesthesia/

Low B12, folate, ferritin and Vitamin D EXTREMELY Common with hypothyroidism especially hashimoto’s

She will need bloods tested

Ideally Thyroid and vitamin tests NOW if still in hospital

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

Ask GP to test vitamin levels

Presumably she has hashimoto’s

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 .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Thyroid....little point doing private testing until been on constant unchanging dose for 6-8 weeks

Thankyou - she’s out of hospital now will get her tested asap

What supplements does she normally take

Does she regularly retest vitamin levels

Obviously extremely important to have good levels of folate and B12 before TTC .....equally important not to have levels too high.

Post on here in last week about research showing both B12 and Folate being Goldilocks vitamins for baby’s development.....not too little...not too much

Stopping Levo on odd days is not going to ever show correct levels when testing

Dose should be constant.

Which heart could be doing due to being under medicated

The heart needs good Ft3

Low iron or ferritin possible cause too

I wonder if your daughter has a sensitivity to the fillers/binders in levothyroxine. I had severe palpitations on levo (T4) but found that some T3 (extremely difficult to get prescribed now due to cost) added to T4, calmed my palps.

Before that the cardiologist was puzzled about why I had constant palpitations (especially during the night) he was thinking of putting an implant in heart to 'see what was going on'. Coincidentally some T3 was added to T4 and I never saw cardio again as palps ceased.
