Is too much calcium from the para thyroid related to under active thyroid disease?

I have had been hypothyroid for over 30 years and latterly have a range of symptoms. I have now been told by my GP (one of many) that my parathyroid is making too much calcium. I have been suffering with a lot of bone and muscle aches which seems to be getting worse. Can anyone shed any light please? Thanks Harper

The parathyroids don't make calcium, they release parathyroid hormone which controls calcium levels, this might help explain it


This is a link re the Parathyroid Gland:-


Hi I recently had a mammogram, which showed calciforcation in my L breast I was given a biopsy and had a marker inserted and it will be used in future test , were Neg ,does this indicate, that calcium can deposit in soft tissue, is another issue with Hypo and Levo 125 mic


Hi if the calcium is over range ( corrected calcium) it is important to stop taking any vitD.It is all Endo. If you have a test for PTH, Calcium and vit D , done together , must be AM, all high, or 2 high and D high for you. over range.Then if out of range. GP is not correct. You then need a nuclear scan and CT together for PTH, no other way, large teaching hospital, and also an ultra sound of thyroid. If there is a problem shown with PTH, essential to have surgery. This can be separate from thyroid disease but is Endo. PTH can cause very serious conditions , also thyroid, and is easily corrected. in the mean time if corrected calcium reaches 3, after 2 consecutive tests, you need to go into hospital for an IV, dangerous, but calcium over 3 more so.

Best wishes,



Chapter 12 in Dr Barry Durrant-Peatfields book - The Thyroid and How to Keep it Healthy - does mention the connection in the control of calcium. The job of the parathyroids is to keep the calcium in the blood in quite a narrow range. When calcium levels are high in the blood then the thyroid secretes calcitonin to reduce it....He also mentions that a poorly functioning thyroid cannot produce adequate supplies of calcitonin - although apparently the parathyroids seem able to cope with this....

Are you taking too much VitD - which can stimulate calcium production. I have also read that Magnesium is at play in this situation - sorry do not have the reference to hand....


Don't know if this is of any help but i had high calcium and after they run a few blood tests,it was due to levothyroxine being to high,once they lowered it ,the high calcium went away.
