Treating renal, or kidney, disease involves treating the underlying causes of the disease, which are often high blood pressure and diabetes, according to WebMD. Treatment options for kidney failure as a result of end-stage, chronic renal disease include dialysis and kidney transplants, states Mayo Clinic.
Controlling diabetes through diet, exercise and medication helps slow the progression of kidney disease, states WebMD, because persistently high blood sugar levels can damage the tiny blood vessels in the kidneys that filter wastes from the blood, a condition called diabetic nephropathy. High blood pressure can both cause kidney damage and be a result of it. Treating high blood pressure with medications may stop the progression of the kidney damage it causes, while lowering the amount of protein in the urine, which also helps the kidneys function.
In addition, WebMD recommends supporting kidney health by exercising regularly, avoiding alcohol and other substances that can harm the kidneys, and eating a kidney-friendly diet that includes the correct amount of sodium, protein and fluids.
If renal disease progresses to kidney failure, dialysis is required to filter wastes, electrolytes and excess fluid from the blood, states Mayo Clinic. Dialysis is performed by running the blood through an external filter, usually three times per week, or filtered daily through the lining of the abdominal cavity, states the National Institutes of Health. Removing a failed kidney and transplanting a healthy one requires no further dialysis, states NIH.
