I have Hashimotos and have been on T4 and T3 for six years. During the six years I have had low blood pressure, usually below 110/70 but I

have been taking NDT only, for the last two weeks and my blood pressure has increased to 130/85. Would this be caused by NDT?

Blood pressure has to do with thyroid also? Mine is usually 90x60!

Jaie, have you had a thyroid blood test since switching to NDT? Perhaps you should check that you aren't over or under medicated which might affect BP.

[Jaie]

Thanks for the replies. Clutter I haven't had a blood test since I started on NDT as I live in France and can't tell my Endo I am taking NDT. I believe NDT is illegal in France.

[Clutter in reply to Jaie]

Jaie, it's certainly illegal to import it. Post your most recent thyroid bloods, the amount of T4 and T3 you were taking and how much NDT you've switched to and we'll have a looky. It's hard to see why switching from T4 and T3 to NDT which contains both would cause a rise in BP if you've got the NDT dose roughly equivalent.

[Jaie]

TSH 0,015 (0.47 - 4.68)

T4 14.00 (10.00 - 28.20)

T3 6.34 (4.00 - 8.30)

I was taking 100mcg of T4 and 45mcg of T3.

I stopped the T4 and T3 and started on 1 grain, felt fine so increased the dose every few days until I was on 4 grains. After a few days I had a tight feeling in my chest and felt breathless so I reduced the dose and I am now on 2 grains. Thanks for your help.

[Clutter in reply to Jaie]

Jaie, I think the reason for your BP rising is likely that you increased NDT too quickly and too much and overmedicated. 4 grains is roughly equivalent to 300mcg T4. 45mcg T3 plus 100mcg T4 is roughly equivalent to 235mcg T4.

[Jaie]

Thanks again, I will stay on 2 grains and see how I feel.

Hi Jaie, this might be some help, as lots of helpful info about NDT dosage:
