Thyroid and blood pressure association

[userotc]

Id welcome any views on the relationship between BP (high or low) & thyroid. A quick search on this forum indicates relatively little information but some anecdotal evidence that hypothyroidism can raise BP. But a scientific literature search is less clear (see below links & some key comments):

Some key comments on above reports:

1st link: relationship & mechanism for low T3 causing hypertension

2nd link: T3, T4 associated with hypertension

3rd link: Hypo & hyperthyroid can raise BP but "results of clinical studies are often controversial"

4th link: Uncertainties with need for RCTs

The only link I have on the subject is this one :

Many thanks for your reply. Re the link you kindly sent, Ive not been diagnosed with thyroid disease or on T4 meds. It was suggested on this forum a while ago that I may have central hypo but I avoided levo option (maybe good decision according to link?). And a Medichecks doctor reported for my last Advanced Thyroid test results 2.5y ago re CH:

"This illness tends to cause a low thyroxine and a low/normal or low thyroid stimulating hormone. Thyroxine probably tends to be a bit lower than we see here and the thyroid stimulating hormone would often be a bit lower too. As there is a chance you may fit the picture let's look a bit deeper and fortunately you've already done some of the other hormonal tests. Looking at everything together I think it's unlikely that you have central hypothyroidism".

Whilst Im generally against medics (!), he seems quite adamant although he did go on to suggest a retest and neuro-endocrine referral if results low.

My BP is not below range at ave 112/69 (so diastolic slightly more of a concern than systolic mentioned in your link for low BP?) but I often get dizziness etc symptoms when I think its dropped further. NaCl supplements dont seem to help.

Note: The underlying cause is likely a prescription medication (as per my profile).

I may retest thyroid soonish and then consider a Nutritional Therapist that specialises in it or maybe consider retrying a thyroid glandular first.

I've been testing my heart rate, BP and basal temp several times a day (except on office days) since I went onto combination therapy back in July.

My symptoms are 100% hypothyroid and my blood pressure is almost always raised and my basal temperature is always below 38.8.

So for me there is a clear link between hypothyroidism and blood pressure.
