Hyperparathyroidism causing hypothyroid? Or the other way around

[rach260190]

Hi everyone I'm just looking for some info and help regarding parathyroid and thyroid problems, if they can Co exist or one can cause the other.

A few months ago I was diagnosed with hypothyroidism and hyperparathyroidism.

My tsh was about 4.2 6.8 8.0 etc so always elevated. My calcium was 2.70 2.69 2.61 2.74.

I also have osteopenia in arms spine and on the way in my neck.

I have read that thyroid problems can rise calcium levels as there can be a problem with calciton. Which acts against the parathyroid hormone. Calcitonin decrease calcium levels in blood and phosphorus.

Where as parathyroid hormone increases blood calcium and phosphorus loss.

I have a lowish vit d low to low normal phosphorus and raised calcium.

I was started on a low dose of thyroxine which raised my free t4

I was also started on cinacalcet to normalise my calcium and supress parathyroid horome.

Since normalising my calcium with cinacalcet the low dose of thyroxine has made me hyperthyroid so I have now been told to stop taking thyroxine.

So I am thinking and so are my doctors that my parathyroid problem had caused a problem with my thyroid since my calcium has been normalised my thyroid has normalised.

However I know it is very complicated

but surely if I just hadon't a thyroid problem it wouldn't be causing high calcium and low phosphorus.

All so confusing... maybe I'll health and a parathyroid problem has caused issues with my thyroid regulation. .

Any help would be great thanks much appreciated

Do you have copies of your blood test results, with the ranges, as it makes it easier for members to comment. I don't know much about the parathyroid so cannot help. Even though the state 'normalized' maybe it is not 'normal' for you.

This is a link which may be helpful. Hyperpar... is on the left-hand side.

It's not unusual to have both thyroid and parathyroid problems, are you being treated ?
