Dietary salt intake

High dietary sodium intake may increase the risk of hypertension and cardiovascular disease. The effect of dietary restriction of salt in foods has been investigated in people with chronic kidney disease. A 2021 Cochrane review of controlled trials in people with CKD at any stage, including those on dialysis, found high-certainty evidence that reduced salt intake may help to lower both systolic and diastolic blood pressure, as well as albuminuria. However, there was also moderate certainty evidence that some people may experience hypotensive symptoms, such as dizziness, following sudden sodium restriction. It is unclear whether this affects the dosage required for anti-hypertensive medications. The effect of salt restriction on extracellular fluid, oedema, and total body weight reduction was also uncertain.
