Tertiary hyperparathyroidism means excess production of parathyroid hormone that has escaped all normal body feedback controls and so persists even in cases where the initial cause (low blood calcium) has been corrected.
How do you know if you have primary or secondary hyperparathyroidism?
If your doctor said you have secondary hyperparathyroidism because your vitamin D is low, then check your calcium. If your calcium is high, then you have primary hyperparathyroidism, not secondary.
