While a renal diet is unable to prevent the development of kidney failure, it can help damaged kidneys work more efficiently, explains Drugs.com. It does this by balancing the amount of fluid, electrolytes and minerals in the body and reducing the amount of waste products that can build up in the bloodstream due to impaired function. A renal diet changes according to the severity of the kidney disease and the needs of the patient.

Chronic kidney disease, or CKD, refers to any number of conditions that damage the kidneys and prevent them from doing their job of removing metabolic waste from the blood, notes The National Kidney Foundation. Uncontrolled high blood pressure and diabetes are the two most common causes of CKD, comprising two-thirds of all cases. Other causes include lupus or other autoimmune conditions, repeated or persistent urinary tract infections, structural abnormalities and diseases that cause inflammation of the filtering structures within the kidney.

Additional risk factors for kidney disease include older age, a family history of kidney dysfunction and a history of cardiovascular disease according to Mayo Clinic. African-Americans, Native Americans and Asians are also at increased risk.
