What sodium intake is advised for CKD patients with proteinuria?

For patients with chronic kidney disease (CKD) who have proteinuria, a sodium intake of less than 2300 mg per day is recommended. This guideline is based on the understanding that high sodium intake can lead to increased blood pressure and further kidney damage, which is particularly concerning for those with CKD. Proteinuria itself often indicates a more advanced stage of kidney impairment, and managing sodium intake is a critical aspect of dietary interventions to preserve kidney function and manage overall health.

Reducing sodium intake can help decrease fluid retention and lower blood pressure, which is essential for preventing complications associated with kidney disease. The recommendation aligns with dietary management policies aimed at providing a protective effect on kidney function while also addressing cardiovascular risk factors that are often present in CKD patients.
