Why do patients with CRF on dialysis suffer from bone pain? Question:

Hello, Doctor! My husband is already on hemodialysis and he has CRF (chronic renal failure). Now he have much complains of the strong pains of the bones of the thigh and lower leg. Why is this? Why do patients on dialysis suffer from bone pain?

Causes of pain in chronic renal failure:

In CRF, bone cells: osteoclasts and osteoblasts are kept in balance, and so there is renal cystic disease. When calcium, parathyroid hormone, phosphorus and vitamin D are not in imbalance, the kidney disease of the bones arises.

CRF means that the kidneys are already severely impaired and most of the kidney functions are lost and as a result, excess phosphorus can not be removed by the kidneys and high phosphorus interferes with the absorption of calcium.

Moreover, during dialysis, blood does not flow through the kidneys and so ischemia and hypoxia in the kidneys are aggravated, and therefore on the dialysis program the kidneys will be worse and worse.

How to relieve bone pain in patients on dialysis?

Treatment should restore the balance of calcium, parathyroid hormone, phosphorus and vitamin D. Usually, phosphorus binders, rich vitamin D and a decrease in the intake of phosphorus are needed.

Why do patients with CRF on dialysis suffer from bone pain?

Of course, you need treatment for kidney repair, to improve kidney function and reduce the frequency of dialysis.
