Full Answer

There are five stages of chronic kidney disease, according to The Renal Association. The first stage is normal kidney function, in combination with genetic traits or urinalysis abnormalities. Stage 2 is abnormal urinalysis or genetics in the presence of mildly reduced kidney function. The third stage indicates moderately reduced kidney function, while stages 4 and 5 reveal severely and very severely reduced kidney function, respectively. These categories are more precisely defined by a numerical measurement known as the glomerular filtration rate, or GFR. During stage 1 chronic kidney disease, the GFR is above 90, and in the fourth and fifth stages, it is below 30, necessitating dialysis.

When the filtering process of the kidneys becomes dysfunctional, disruption occurs in several crucial areas of the body. Mineral and electrolytes become unbalanced, water-soluble waste collects, the pH balance of the blood is disturbed, and the production of red blood cells is interrupted, according to Healthline. The most common causes for kidney disease include diabetes and high blood pressure, as reported by the National Kidney Foundation.
