Salt Substitutes may pose hazard for Hemodialysis, Dialysis, Chronic Kidney Disease (CKD) and End Stage Renal Failure (ESRD) Patients.
While limiting salt (sodium chlorida NaCl) is often recommended as a means of moderating hypertension, salt substitutes pose a potential danger for some kidney failure patients. Patients with
failing kidneys may not be able to eliminate potassium, an important mineral for life, but in excess amounts can lead to life threatening heart arrhythmias.
Salt substitutes may contain higher amounts of potassium in exchange for lower amounts of sodium chloride. The excess potassium can lead to hyperkalemia (or elevated potassium in the blood) that can cause conduction problems in the heart causing an irregular heart rate or arrhythmia. Please consult with your nephrologist, dietician or health care provider before using a salt substitute.
