low blood pressure

[Cecilbenhard]

is low blood pressure associated with an underactive thyroid?

[greygoose]

Low blood pressure is a symptom of hypo, yes. It's one symptom that doctors actually know about!

[Cecilbenhard in reply to greygoose]

Thank you greygoose - yet another symptom to try and convince my GP!

[greygoose in reply to Cecilbenhard]

Well, he really should know that. It's basic thyroid 101.

Sadly these days they only seem to take note of TSH....🙈 As one GP told me...... symptoms are old hat we go on bloods and scans! Marvelous!!

😞

[greygoose in reply to waveylines]

What a very, very stupid thing to say! Doesn't give you much confidence in his level of intelligence, does it. Obviously he's never experienced symptoms of anything. He'd get very short shrift from me!

[waveylines in reply to greygoose]

Female doctor....lol......

[greygoose in reply to waveylines]

No excuse!

[waveylines in reply to greygoose]

Even worse in my book!!

i've read in several papers that untreated hypo causes high diastolic pressure ( the second number) , and iv'e seen it mentioned that low systolic pressure ( the first number ) can be a symptom in myxoedema coma,( which is very severe hypo , but doesn't necessarily mean you have to be in a coma)

i remember reading in various places that hypothyroidism causes 'narrow pulse pressure' , which means the difference between the systolic and diastolic numbers is less than usual ~but i've not seen anything that mentions 'low blood pressure' ( if that means both numbers are low ?) as a symptom of hypo.

this post has a collection of papers about affects of thyroid hormones on heart (list is at the end of replies) : healthunlocked.com/thyroidu... thyroid-disease-effects-on-heart-and-cardiovascular-system

Thanks tattybogle - maybe mine isn’t low?? It’s 107/56 with a pulse rate of 52 which is low.

according to this , your diastolic ( 2nd number ) is a smidge low , but i don't know if it's low enough to be a concern. And your systolic (1st number) seems fine.

"The NHS has a general guide that can tell you if your reading is within the normal range:

Low blood pressure: under 89/59mmHg

Normal blood pressure: between 90/60 mmHg and 120/80 mmHg

High-normal blood pressure: between 120/80 mmHg and 140/90 mmHg - you may be at risk of high blood pressure in the future"

based on the studies i've read , if hypo was the cause , i'd have thought diastolic would be high not low ? , but i know very little about it other than what i've read .and much of it i don't understand to be honest.

Thank you for taking the time to reply. Im seeing the practice nurse soon so I will talk to her about it x

[waveylines in reply to Cecilbenhard]

If it's from your own BP monitor take it with you so she can calibrate it.

[Cecilbenhard in reply to waveylines]

Thank you

Yes, peripheral vascular resistance caused when Hypo increases Diastolic primarily.

In fact, it's one of only a few causes of IDH.

Left Ventricular issues commonly go hand-in-hand with Thyroid issues for this reason.

Before starting Levo I was always told by anyone taking my blood pressure “That’s nice and low”. Now that I’m on Levo it’s suddenly increased to high normal (I think 130/80 - lower number was 80 or 90). But I’m 71 now so maybe is more linked with age.

[Cecilbenhard]

thanks Bearo, I’m 70 so maybe it is though I’m very careful about diet and exercise generally.
