Hypothyroidism and atrial fibrillation
Posted , 8 users are following.
I suffer from Hypothyroidism and take Natural thyroid hormones. I also get spells of Atrial Fibrillation.
How many of you taking just T4 experiance Atrial Fibrillation. An Endocrinologist felt I might be harming myself by taking NDT, but has not said how I might be harming myself, so it would enlighten me to know if those of you taking T4 also experiance irregular fast heart rate.

and PLEASE. Tell us why your endocrinologist thinks NDT may be harmful...

As a first approximation and not having any of the above numbers I would say your NDT dose is probably too high. Long ago before blood tests the patients would monitor their pulse rate to determine if their dose was too high. If it was, they would reduce thier dose a little and then another little until the fast pulse became normal - I still do this.
The thing Endo's worry about with NDT is that it has T3 and T3 is the active hormone which will give you energy - too much will give you a fast pulse and possibly palpitations. However, the good news is that T3 only has a half life of 6 +/- 2 hours so if you have a racing pulse, miss out the second dose of the day - if that is the way you take NDT.
But anyway, first let us know the numbers so that we can give a more accurate assessment.
Oh, and Dave, another aspect of Endo's and NDT is that Endos do not measure T3, so the patient could be manufacturing thier own T3 via a periferal organ (e.g. the liver). But then the Endo does not measure T3 so they do not know how much T3 their patient ends up with - so it could be a lot, that which they convert themselves and the T3 dose from the NDT. It all takes a lot of measuring via blood tests and for some reason Endos are reluctant to measure. They are flying blind, that's why they could run into a harmful condition.

March 17th results---- FT4 13.65, FT3 5.94, TSH L <0.01 november="" 19th="" results----ft4="" 14.82,="" ft3="" 5.89,="" tsh="">0.01><0.005
it appears that the ft4 has gone up since last time and the ft3 has gone down and the tsh even more suppressed.
is it possible that i need to decrease the ndt and add a little t3.
at present i am taking 3 grains of ndt (thyroid-s) and did not take any before the test this morning. it="" appears="" that="" the="" ft4="" has="" gone="" up="" since="" last="" time="" and="" the="" ft3="" has="" gone="" down="" and="" the="" tsh="" even="" more="" suppressed.="" is="" it="" possible="" that="" i="" need="" to="" decrease="" the="" ndt="" and="" add="" a="" little="" t3.="" at="" present="" i="" am="" taking="" 3="" grains="" of="" ndt="" (thyroid-s)="" and="" did="" not="" take="" any="" before="" the="" test="" this="">0.005

Now I realize that we are two different human beings but my dose is 1.5 grains of NDT (and I had a thyroidectomy due to Th Cancer) and anything over this makes me a bit hyper (and that is bad). 3 grains is considered very high here in the US and I would seriously tell you that this is a high dose and that it is probably causing your atrial fibrilation. Try 2.5 and assess your symptoms, that would be my sugestion.
Does your heart fibrilate just after you have taken your meds? Well, up to 3 hours after, and then calms down? I ask this because T3 has a half life of about 4-6 hours and you are giving your all ready adequate T3 level a big temporary boost just after your pill.

Yesterday I had only taken one grain of NDT after my test and had also been to my photo club in the afternoon, but there was no Afib on getting back but it was noted at 10.00pm.On going to bed I still had Afib and as temp was low at 35.6cc I decided to take another grain of NDT, but as I still had Afib at 3.20am but temp had dropped lower at 35.00cc but I took half the 3.75mg Bisoprolol, but Afib contined until I had my bowels open, but the Bisoprolol had left me with a low BP of 114/55 bpm66 which in turn causes me to be out of breath. I have not taken any NDT this morning and will proceed at 2 grains a day, but I am somewhat confused that my tests indicate too much NDT, but symptoms indicate not enough.

It's a difficult one Kathleen. I would get with your doc again and see what s/he suggests is the next move.

Or could it be your adrenal glands playing up (stress/body trauma is reported to cause this)?

I also had a dizzy spell at the sink on Friday and held onto the sink to stop myself falling and put my head down which helped and then held onto what I could until I reached my bedroom to take my BP and my BP was up and not in Afib but I had taken Bisoprolol in the early hours of that morning. I have cut down the NDT to 2 grains a day and no Afib but my hair is falling out still.
They were also weening me off Prednisolone but I reached 2mg a day and the pain in my muscles and joints got too much and could not get appointment with my GP so increased the Prednisolone myself and now taking 10mg a day. The pain is better than it was and Prednisolone is supposed to help the adrenals.
Before I was diagnosed with HYPO my hair used to fall out then so bad that I had to wear a bonnet to stop it going in the food on cooking.
I have wondered myself if it might be due to RT3 and if to go back to taking just T3 for a bit.
I was none too pleased about them refusing me NDT or even T4 with no explanation and the ENDO I saw said she felt I was harming myself by taking NDT but no explanation as to how. I received a response but still no explanation so have gone back to ask for an explanation again and they have agreed to investigate.
I am not taking Bisoprolol all the time only when in Afib

So this prompts the question: did the hair loss start after your spell in A&E with no NDT?

Before being diagnosed with HYPO I had, had spells of passing out plus having a fall on a bus when having problems with T4. In fact the muscle and joint pains started when taking T4. How can they blame the T3 in the NDT as causing harm and also the test this time for T3 has gone down. My views on T3 is that it can be more rapidly controlled that T4 can although you have to take it several times a day due to its half life. I don't think my hair was faling out when taking T3 only. Could the rise in T4 have caused the TSH to drop so much as it could not be due to the T3.
Could RT3 cause the TSH to fall.

Now if you have an excess of T4 then you will probably have low TSH, but low TSH is not caused by high RT3. Low TSH and high RT3 are both results of excess T4.

My inclination is not to go through surgery to remove the mesh TVT until they get me in a better state.
There is also adenal fatigue that Doctors refuse to admit exists.
I feel positive that the antipsychotic drug I was put on for 13 years prevented the T4 from converting to T3 and the reason my weight went up and up despite being prescribed more and more T4.
