Chronic kidney disease and salt intake

Reducing salt intake provides clear benefits for the heart and kidney health of patients with chronic kidney disease. Excessive salt intake is consistently linked to increased risk of heart disease and worsening kidney function. People with chronic kidney disease (CKD) may be particularly susceptible to salt's detrimental effects due to the kidney's important role in controlling salt balance and their increased risk of dying from heart disease.

Researchers found that on average, low salt intake reduced excess extracellular fluid volume by 1 liter, lowered blood pressure by 10 /4 mm Hg, and halved protein excretion in the urine, without causing significant side effects.

If maintained long-term, this could reduce risk of progression by 30%. Otherwise, progressing to end stage renal disease will require dialysis or transplant. Additionally, research suggests that salt restriction is an inexpensive, low-risk and effective intervention for reducing cardiovascular risk and risk of worsening kidney function in people with CKD.
