Does one on this forum have or had Atrial fibrillation and been advised by Endo that a low TSH can put you at risk for AF ? My TSH was .21 in August and .14 in November .

Olivia, my endo wants TSH <0.1 but it is usually <0.01. Endo's never mentioned atrial fibrillation. The Rotterdam Study finds no association between TSH and atrial fibrillation.

Total hogwash. (in my opinion) My heart symptoms have gone now that my TSH is low and my adrenals are under control.

No is the answer unless you are very frail with a heart condition already.

email louise.warvill@thyroiduk.org.uk and ask for a copy of Dr Toft's Pulse online article and question 6 highlight and give your Endo a copy. You will notice Dr Toft (ex President of the BTA) says some of us need a suppressed TSH.

How is your FT3 looking - if that is over range or under range - that is more like to be a problem :-)

thanks , have spent so much money and now it seems that the advice was incorrect ..... These were my results for August bearing in mind that I took my 1 1/2 grain of nature thyroid at 7am and was told to have blood work ;

The Endo was not interested in any of the results but the TSH

She told me to cut my mess down to 1 grain .... But I do crash and feel tired mid morning ... I do not know what to do .. Even the Endo in the States was. On earned with AF ..only had one incident three years ago .. Lots of stress since moving here ... Live in Leicester and do not know what to do next .. I have two prescriptions ..one for 1 grain and one for 11/2 .... Help ,

Sorry Olivia I do not have any experience with NDT. My only 'suggestion ' would be to check your adrenals and the basics - B12 - Iron - Ferritin - Folate - VitD. Where they are in their ranges is key to your wellbeing. Do you have any results for those ?

My TSH is currently 0.02 (I'm on T3 only) and my endo is not happy, but I've been gathering the evidence that people kindly post to show that this is not necessarily a problem. I've definitely read one article which says between 0.04-0.4 is safe, which means yours would be ok. As Marz says though, FT3 is the important one (mine's still at the bottom!).

Never had it but I do have angina and haven't had an attack since I started NDT. Your doctor is WRONG supressed or low TSH does NOT cause atrial fibulation. Not enough thyroxine may do and remember that TSH is a pituatary hormone NOT a thyroid hormone.
