**3.2.2 Blood pressure control**

Six prospective studies demonstrate improvement in blood pressure control after switching patients to lower dialysate sodium. Blood pressure control is defined as reduction in predialysis blood pressure measures or reduction in number of prescribed antihypertensives. Three studies showed no change in blood pressure control. No study, however, showed worsening blood pressure on lower dialysate sodium. It seems certain that a modest reduction in dialysate sodium can have beneficial influence on blood pressure management.
