Dialysis patients can no longer excrete large quantities of fluids consumed; therefore, excess fluid can be retained in the body resulting in overloading of the blood circulation.Your daily fluid allowance includes plain water, tea, coffee, milk, gravy, soup and porridge.Thus, both peritoneal dialysis and haemodialysis patients will need to consider urine output, remaining kidney function, and body size to restrict their fluid intake.Limited urine output does not indicate dehydration in dialysis patients.
