StageGFR Level
Normal kidney function 90 mL/min or more
Stage 1 90 mL/min or more
Stage 2 60 to 89 mL/min
Stage 3 30 to 59 mL/min
Stage 4 15 to 29 mL/min
Stage 5 Less than 15 mL/min or on dialysis
Stage 1 of Chronic Kidney Disease
Although, the GFR level falls within the normal range, slight abnormalities in the kidney function are reported at this stage. These abnormalities are often an indication of an onset of a kidney disease. However, these abnormalities can only be found in a pathological examination. The treatment options at this stage are abundant. The individual needs to keep his blood pressure under control and also a close watch on kidney failure symptoms is required.
Stage 2 of Chronic Kidney Disease
There is a mild reduction in GFR level which points to a kidney disease. Blood/urine tests, imaging studies are required to find out more about the kidney disease. A proper diagnosis at this stage is necessary to initiate the treatment of kidney disease.
Stage 3 of Chronic Kidney Disease
There is a moderate reduction in the GFR level. Depending upon the GFR level, this stage is further divided into two sub-stages, 3A and 3B. GFR level between 45 to 60 mL/min falls under stage 3A, while stage 3B is more severe, with GFR level between 30 to 45 mL/min. A proper screening at this stage is a must to prevent permanent damage to the kidneys.
Stage 4 of Chronic Kidney Disease
The GFR level drops to 15 to 29 mL/min which is an indication of an end stage kidney failure. Other organs in the body also start affecting due to kidney dysfunction. The only treatment available at this stage is renal replacement therapy.
Stage 5 of Chronic Kidney Disease(ESRD Overview)
The GFR level falls so low that the kidneys almost cease to work. The only treatment available to improve the chances of survival is permanent renal replacement therapy. This treatment is either in the form of dialysis or kidney transplant. More on kidney dialysis process.
Kidneys are one of the most important functional organs in the human body. Unhealthy lifestyle can greatly affect the working of kidneys. Hence, it is imperative that you adopt a healthy lifestyle and drink lots of water to avoid going through any of the kidney failure stages
