title: The effect of dietary salt restriction on hypertension in peritoneal dialysis patients.
abstract: OBJECTIVE
  To investigate the effect of dietary salt restriction on blood pressure levels, total sodium removal, and hydration status of peritoneal dialysis (PD) patients.
  
  
  METHODS
  Thirty-one stable PD patients who consulted a renal dietitian monthly for dietary recommendations, including restricted salt intake <5 g/day, and education about hypertension and hypervolemia were included in this study. Baseline and third month clinical and laboratory findings, bioelectrical impedance analysis results, and urinary and peritoneal sodium removal values were recorded.
  
  
  RESULTS
  The mean age of the patients was 47.6 years and the mean time on PD was 39.6 months. The mean total sodium removal decreased slightly from 139.4 ± 69.1 to 136.2 ± 64.8 mmol/day (P > 0.05) for the whole sample, and from 164.3 ± 70.9 to 154.2 ± 72.3 mmol/day (P > 0.05) for the hypertensive subgroup (n: 17). Systolic blood pressure (from 134.3 ± 20.1 to 127.2 ± 19.5 mmHg, P: 0.01), diastolic blood pressure (from 83.2 ± 12.0 to 77.4 ± 10.5 mmHg, P: 0.01) and total body water (from 39.2 ± 10.9 to 38.3 ± 9.3 L, P: 0.04) decreased significantly.
  
  
  CONCLUSIONS
  We demonstrated that even a little reduction in daily dietary sodium intake caused significant decreases in blood pressure levels and fluid overload.
