I have been under endocrinologist at my local hospital (Cornwall) for about five years. I have progressed from T4 to combined T4 T3 and then to T3 only.
A year or so ago I saw a locum about something else, she looked at my bloods and referred me back to endo. without my knowledge. The consequence was I saw another endo. who insisted I needed to take T4 and reduce T3 until on T4 only. I didn't do this and fought off requests to do so. In sept. my gp came back (been away for a year.) and called me in . He suggested I add 25 mcg. T4 and see how I go. Endo. had put that no T4 would endanger my heart in my notes. I did as requested and was ill. Vertigo breathing problems and worse of all blood pressure rising dramatically.
On reporting these symptoms my gp suggested a visit to a different hospital (Devon).
The appointment has just come through and I want to be well armed but not demanding of this new endo.
So do I need T4 for my heart? is this a long term condition that might develop over years? Since stopping T4 my BP is back to normal as are breathing and vertigo.
In the years of T3 only I have not lost weight or had any symptoms over overactivity.
