[ Summary ] | In dialysis patients, abnormal metabolism of calcium(Ca) and phosphorus(P) frequently develops due to decreased excretion of P from the kidney and the decreased absorption of Ca from the intestine resulting from vitamin D deficiency. Low serum Ca and high serum P lead to renal osteodystrophy due to the overse cretion of parathyroid hormone, and high Ca-P products increase the risk of metastatic soft tissue calcifications, especially within the cardiovascular system. To prevent these serious complications, dietary guidance on Ca and P intake is very importants. Food high in protein and/or Ca contents are usually high in P and must be therefore restricted in dialysis patients. High P containing foods are dairy products, fish and shellfish, liver, buckwheat noodles, and preserved food. If protein intake is adequate, there is almost always a requirement for phosphate binders to appropriately control serum P. Based on clinical laboratory data, the status of complications, the medications taken, and the patients' food preferences, dietary P intake should be aggressively restricted in order to maintain a healthy nutritional status in dialysis patients. |
