Hypo, Fast heart rate, low blood pressure

Hello,

I have a fast heart rate but low blood pressure and my cardio wanted to put me on a very low dose of beta blockers. I am borderline hypothyroid and my cardio said my heart is fine, it's my thyroid giving me the fast heart rate.

So, my question is: How do I take a beta blocker when my blood pressure is already low? Its always 90/60. Btw, my heart rate is only fast when I'm anxious (like at the dr's office where it spikes to 130) but my resting heart rate is consistently in the 70s-80s based on a holter and months of me documenting my bp and heart rate at home with a bp cuff. Once my cardio saw that, he told me use of the beta blockers is up to me.

Also, my endo took me off synthroid 3 months ago bc of the fast heart rate. But I believe with or without synthroid the heart rate is still the same -- spiking when I have anxiety.

Any suggestions?

Dehydration can cause low bp and fast heart rate.  I started a very low dose of a beta blocker 9 months ago because I became hyperthyroid.  I had borderline high bp though so that was not a concern (especially at the docs where it was very high).  Now that my thyroid has normalized a bit however, my heart rate and bp are going too low.  If you are like me, I too get the fast heart rate at the docs office.  I also get elevated bp.  I think if your heart rate is normal most of the time (as you said it was tested) and your bp is low, you do not need a beta blocker.  It is probably just the anxiety causing the fast heart rate.  If you are anxious MOST of the time, this is essentially the same thing as having a fast heart rate all the time, but if it is just on occasion, I wouldn't worry about it.  What might be more helpful is controlling your anxiety.  Maybe going to a therapist would help?  I know thyroid disease has a direct impact on anxiety, so you are not alone in this problem.  I am anxious all of the time.  Good Luck,

Danielle

Thanks Danielle! Yeah, anxiety is a big problem for me lately. Since I am borderline hypo I only used to take half of 25mcg and that actually helped me. But the endo took me off bc of concerns about heart rate. I want to get back on bc now I feel even more anxiety and fatigue.

Do you know if the anxiety goes away when your thyroid levels normalize? I really really hope so, bc this is by far my biggest and most troublesome symptom.

Thanks!

I am working on my master's in health psychology and my interest is actually hypothyroidism and it's relationship to anxiety.  I'd say when levels are normalized you definitely have an improved chance of the anxiety decreasing.  I do believe however in essentially a pandora's box.  Once anxiety is started (by any means), you basically classically condition yourself to having it even when the thyroid is normal.  It might get better, but your anxiety might very well need some further treatment.  I agree that it is one of the worst symptoms I experience.  I wish you well and really hope you have a decrease in it.  Have you tried natural breathing techniques or anything to aid in this?  I find it really does help!

I think that's great that you are focusing on hypothyroid and anxiety, since most people (dr.'s especially) say it's only a hyper symptom. What I think is that if you already had mild anxiety/nervousness throughout your life (like me), any thyroid problem is only going to make it sooo much worse, which is what's happening to me now.

I have tried natural breathing techniques and it definitely helps particularly in bringing my fast heart rate down. I've also gotten off of caffeine, chocolate, white sugar, and take a strong multivitamin and separately take Vit D 5,000 IU daily, and in general eat a lot healthier. I also stay well hydrated, including drinking coconut water almost daily. All have helped tremendously. I think walking, exercise helps too.

But anxiety is always there, and I'm okay with that but would like to bring it to the normal levels that I used to have, which I believe can happen (I hope) when my thyroid levels normalize. If you come across any other useful information that might help me (only natural, no drugs), please do share.

Thanks Danielle!

Doctor's tend to only believe hypothyroidism can cause depression, but this is simply not true.  I have found countless peer reviewed studies proving this.  I am also a natural remedy person so I do try a few things that help tremendously with the anxiety.  I'll send you a PM of some natural, safe drug free things I have tried to help with the anxiety.
