Kidney disease can affect your body’s ability to clean your blood, filter extra water out of your blood, and help control your blood pressure. It can also affect red blood cell production and vitamin D metabolism needed for bone health.
The kidneys are two bean-shaped organs. Each kidney is about the size of a fist. Your kidneys filter extra water and wastes out of your blood and make urine. Kidney disease means your kidneys are damaged and can’t filter blood the way they should.
Dietary restrictions vary depending on the stage of kidney disease.A kidney-friendly diet, or a “renal diet,” usually includes limiting sodium and potassium to 2,000 mg per day and limiting phosphorus to 1,000 mg per day.
Damaged kidneys may also have trouble filtering the waste products of protein metabolism. Therefore, individuals with chronic kidney disease in stages 1–4 may need to limit the amount of protein in their diets.
However, those with end-stage renal disease undergoing dialysis have an increased protein requirement.
