Been taking T3 for a couple of months and my already low blood pressure has gone down this week.

This week my waking blood pressure has gone down to about 45/78. It is usually about 55 /85. I'm gradually working up my T3 dosage and am now on about 47.5 mcg. Does anyone have any idea why this change has occurred or any advice please?

Have a look at this link - scrol down to the "heart" heading for an explination.

Hope it helps.

The first number should be bigger than the second in a blood pressure reading!

Could you check and confirm what you meant, please?

Sorry. I meant to say 78/45.

That's OK - it is what I assumed - but I have been stung by making bad assumptions!

Hi Waking BP can be low but your systolic BP is too low. Does it go up OK during the night. I now have low BP due to major heart problems and an ICD. However when I went on T3, ages ago, it did not effect my BP.Is your NA level normal ? you may need to have some salt, not too much because it is an electrolyte and can badly affect the heart if too high, just in range is ideal. Also I would ask for U`s and Es and magnesium, separate test and calcium to check all the electrolytes.All simple blood tests. if this does not work ask for a 24 hour BP monitor.When my heart kept stopping my BP was highish, on treatment for it.It does go low when n high AF and with various arrythmias. ( which I cannot spell! ) I hope this helps. Main thing is how it is the rest of the day.
