What Are the 5 Stages of Renal Disease?
Renal, or kidney, disease is often a slow and insidious disease process. Most of the time, people with early kidney disease have no symptoms and are unaware that their kidneys are starting to fail. There are five stages of chronic kidney disease, defined by the change in glomerular filtration rate (GFR), which measures how well the kidneys are removing waste from the blood. The National Kidney Foundation states that 20 million Americans have some degree of kidney failure; diabetes and high blood pressure are frequent causes of renal disease.
