How can a low-sodium diet help me if I have kidney disease?

Melissa Stinson, NP
Nephrology
A change to a low-sodium diet can slow the progression of kidney disease by lowering blood pressure, helping blood pressure medications work more effectively and also lowering protein spillage in the urine. Limiting your salt intake can also improve uncomfortable symptoms, such as swelling of the legs and ankles. A low-sodium diet not only is essential if you have kidney disease, but it can reduce your risk of other serious complications, such as stroke, heart failure and aneurysm.
Controlling salt (or sodium) in the diet is very important for patients with chronic kidney disease. Higher levels of salt can cause higher blood pressure and higher blood pressure in turn causes more kidney damage. The kidneys also lose the ability to filter salt from the blood as the disease gets worse, which makes the salt levels in the blood higher.
