Kidney disease develops gradually over time. Understanding the stages of kidney disease can help patients and families recognize the importance of early detection and treatment.
Kidney disease is commonly divided into five stages based on a measurement called the estimated glomerular filtration rate (eGFR). This test measures how well the kidneys filter waste from the blood.
Higher eGFR values generally indicate better kidney function. As kidney disease progresses, the eGFR decreases.
Kidneys filter waste effectively.
Diabetes, high blood pressure, family history, obesity.
May begin silently with no symptoms.
Kidney function declines over time.
The kidneys are still working well, but tests may show early damage such as protein in the urine.
Kidney function is slightly reduced. Most people still have no obvious symptoms.
Kidney function is more noticeably reduced. Some people begin to develop symptoms.
Close monitoring is needed. Planning for advanced treatment may begin.
The kidneys can no longer filter waste effectively. Dialysis or transplant may be required.
In Stage 1, the kidneys are still functioning well, and the eGFR is usually normal or high. However, there may be signs of kidney damage, such as protein in the urine.
Kidney function is slightly reduced, but many people still experience few or no symptoms. Early treatment and lifestyle changes can help prevent further damage.
At this stage, kidney function is moderately reduced. Some people may begin to experience symptoms such as fatigue or swelling.
Kidney function becomes significantly reduced. Doctors typically begin preparing patients for possible dialysis or other advanced treatments.
Stage 5 occurs when the kidneys are no longer able to adequately filter waste from the blood. At this point, dialysis or kidney transplantation may be necessary to support life.
Kidney disease often progresses silently. Many people do not realize they have kidney problems until the disease has reached advanced stages.
Regular screening for people with diabetes, high blood pressure, or a family history of kidney disease can help detect problems early and allow treatment to begin sooner.
If you have diabetes or high blood pressure, regular kidney screening can help detect early changes before serious damage occurs.
