explain secondary hyperparathyroidism leading to renal osteodystrophy |
|
Definition
the commonest cause is CKD. decreasing kidney fx means the kidneys cannot convert enough vitamin D to its active form and are not able to excrete phosphate properly. this causes the formation of insoluble calcium phosphate and removes calcium from the circulation resulting in hypocalcaemia.
parathyroid glands detect this and release PTH to try and raise serum calcium. this is done in many ways including increasing the osteoclasting activity of bone which causes renal osteodystrophy. |
