On starting dialysis sodium intake should be limited to below 100mmol, equivalent to 6 g salt/day. When dialysis patients become anuric their fluid and sodium intake needs to be further restricted, to 1 litre fluid/day and 80100 mmol sodium/day. In patients able to maintain a urinary output above ll/day, fluid restriction of 1.5-2 l/day and more flexible sodium intake may be appropriate. Residual urinary excretion is maintained for longer in PD than HD patients and hence fluid and sodium intake can initially be more liberal in PD patients.
