Secondary Hyperparathyroidism

It is the activity increase in the parathyroid glands due to low calcium or high phosphorus levels.  Secondary hyperparathyroidism is a common complication of chronic renal failure.


In patients with chronic renal insufficiency, the inability to discharge phosphorus received by food with the urine result in hyperphosphatemia and then hypocalcemia. Hypocalcemia stimulates PTH secretion and also hyperphosphatemia reduces the synthesis of vitamin D.


Total parathyroidectomy (removal of all glands) and autotransplantation (planting of a part in the body) are performed or 3.5 glands are removed.
