I am a double board certified clinical doctor and can help you with this.

what is your question?

You have vitamin D defeciency.

You have insulin resistance which indicates possible pre diabetes, or bad diet.

The parathormone is concerning, but there is no calcium.

If that is not high, then it needs to be repeated.

Thyroid values are normal.

The slightly high c peptide goes along with the high insulin, and shows that you do have some insulin


I would want to see your diet in detail.

I would want to see an ionized calcium level.

In fact, the low vitamin D can be stimulating the parathormone levels, and that is most likely at this point.
