ombowstring..As your EXCESS Parathyroid Leeches Calcium from your bones..Your Vit D level drops..!!! Inversely when you’re deficient in Vit D ..And therefore unable to absorb Calcium from your Gut..Your Parathyroid level rises..!!!
I have only seen Vit D replaced in ASYMPTOMATIC PARATHYROID ADENOMA..Which yours is NOT..That also with a very careful follow up of serum and urinary CALCIUM..!!!
I am intrigued at your ENDOCRINOLOGIST agreeing with your Vit D supplementation..With your KIDNEY STONES..!!!
