i can’t speak to your need for parathyroid surgery, but i can tell you that parathyroid hormone is critical to the function of Vitamin D, namely that the form of Vitamin D that one consumes is D3, which is converted to D2 in the liver, but the active ,D1, is converted from D2 under control of parathyroid hormone, so if you lack parathyroid hormone, little or no D1 gets produced ... so, regardless of surgery, IF you end up with little or no parathyroid hormone, you’ll have to take prescription D1 AND be very careful with the dose, because too much D1 can be toxic ...
you might want to quiz your doc about this situation and see what he says ...
one other thing that would be helpful at some point is daily 360 micrograms of Vitamin K2 MK-7 form, which bona fide peer-reviewed published research has shown that it is essential for the balance of calcium between the bones and tissues, namely MK-7 keeps calcium in the bones and out of the tissues ...
good luck ...
Do you ever consider contraindications with Vit K for people who take Coumadin? Your overwhelming need to dispense medical advice appears to lack a thorough knowledge of the complexity with drug interactions.
