Management of Hyperphosphatemia

❖ Dietary phosphate restriction 800-1,000 mg/day

❖ Phosphate binders

❖ To minimize the rest of phosphate balance

❖ Dialysis Phosphate removal

❖ Hemodialysis 20-40 mmol/session

❖ Peritoneal dialysis 10-12 mmol/day

Phosphate Restriction

❖ 800-900 mg/day

Treatment of CKD-MBD: Phosphorus and Calcium

❖ 4.1.5: In patients with CKD G3a-G5D, decisions about phosphate-lowering treatment should be based on progressively or persistently elevated serum phosphate (Not Graded).

❖ 4.1.6: In adult patients with CKD G3a–G5D receiving phosphate-lowering treatment, we suggest restricting the dose of calcium-based phosphate binders (2B)
