How Many Stages of Kidney FailureChronic Kidney Failure (CKF) is a slow progressive process and it is divided into five stages based on GFR (glomerular filtration rate). This can help the doctor to give the best care and treatment for the patients. The patients themselves can also take some measures to slow down the progression of Chronic Kidney Failure. You can get a general understanding of it from this article.

Glomerular Filtration Rate (GFR)

Glomerular filtration rate (GFR) is the best measure of kidney function. The GFR is the number used to figure out a person’s stage of kidney disease. A math formula using the person’s age, race, gender and their serum creatinine is used to calculate a GFR. A doctor will order a blood test to measure the serum creatinine level. Creatinine is a waste product that comes from muscle activity. When kidneys are working well they remove creatinine from the blood. As kidney function slows, blood levels of creatinine rise.

Five stages of Chronic Kidney Failure

♦ Stage 1: with normal or high GFR (GFR > 90 mL/min)

♦ Stage 2: Mild kidney damage (GFR = 60-89 mL/min)

♦ Stage 3:

- Stage 3A: Moderate kidney damage (GFR = 45-59 mL/min)

- Stage 3B: Moderate kidney damage (GFR = 30-44 mL/min)

♦ Stage 4: Severe kidney damage (GFR = 15-29 mL/min)

♦ Stage 5: End Stage Renal Damage (ESRD) (GFR <15 mL/min)


No matter which stage of kidney disease you are in, you can take some measures to slow down or prevent the aggravation of the kidney disease. You can do as follows:

♦ Eat and drink restrictedly

- Low sodium intake in any stage of kidney disease

- Moderate protein intake: Target protein intake for people with Chronic Kidney Failure stages 1-4 should be 0.8g/kg body weight per day. Yet, for people with End Stage Renal Disease, they are recommended to take protein for stable maintenance hemodialysis patients is 1.2g/kg body weight/d.

- Low potassium and phosphorous diet

- Enough vitamins and calories
