Phosphate control essential for prevention and management of renal bone disease, arterial stiffening and vascular calcification.
Phosphate in the diet generally associated with intake of protein: Meat, fish, chicken, eggs, yoghurts, cheese, milk
Typical UK intakes of phosphate: – Men: 47mmol/day – Women: 36mmol/day
When GFR deteriorates to 25-30ml/min, phosphate retention can occur. Level of restriction depends on treatment mode, residual renal function, dietary intake, and biochemistry. Phosphate not very well dialysed – relatively large ion, with small gradient as plasma concentration low (1-2mmol/l).
Aim to maintain serum phosphate <1.8mmol/l. Control can be achieved via combination of:
|Low phosphate diet
Phosphate binding medication:
