Introduction
Many people search for "kidney failure levels" after receiving abnormal kidney function test results or being diagnosed with chronic kidney disease (CKD). Understanding the different levels of kidney function helps patients recognize the severity of their condition and the importance of early treatment.
Kidney disease usually develops gradually over time. Doctors evaluate kidney function using the Estimated Glomerular Filtration Rate (eGFR), along with blood tests, urine tests, imaging studies, and clinical findings. As kidney function declines, the disease progresses through different stages, with Stage 5 representing kidney failure.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, personalized treatment plans, dialysis planning, kidney transplant evaluation, and long-term kidney care to help preserve kidney function and improve quality of life.
What Is Kidney Failure?
Kidney failure occurs when the kidneys lose most of their ability to:
-
Filter waste products from the blood
-
Remove excess fluid
-
Maintain electrolyte balance
-
Regulate blood pressure
-
Support red blood cell production
-
Maintain healthy bones through vitamin D activation
Kidney failure may develop gradually due to chronic kidney disease or suddenly because of acute kidney injury.
How Are Kidney Failure Levels Determined?
Kidney function is primarily assessed using the Estimated Glomerular Filtration Rate (eGFR).
The eGFR is calculated using:
-
Serum Creatinine
-
Age
-
Sex
-
Other clinical factors
Doctors also consider:
-
Protein in the urine
-
Blood pressure
-
Medical history
-
Imaging findings
-
Overall health
A single creatinine value alone does not determine the stage of kidney disease.
Stages (Levels) of Chronic Kidney Disease
Stage 1
eGFR: 90 mL/min/1.73 m² or higher, with evidence of kidney damage.
Characteristics include:
-
Normal or near-normal kidney function
-
Possible protein in the urine
-
Structural kidney abnormalities
-
Usually no noticeable symptoms
Early treatment helps prevent progression.
Stage 2
eGFR: 60–89 mL/min/1.73 m² with evidence of kidney damage.
Many patients continue to have few or no symptoms.
Regular monitoring is recommended.
Stage 3
eGFR: 30–59 mL/min/1.73 m².
Stage 3 is divided into:
-
Stage 3A
-
Stage 3B
Possible symptoms include:
-
Fatigue
-
Mild swelling
-
High blood pressure
-
Changes in urination
Timely treatment can slow further kidney damage.
Stage 4
eGFR: 15–29 mL/min/1.73 m².
Kidney function is severely reduced.
Patients require close follow-up and preparation for possible kidney replacement therapy if needed.
Stage 5 (Kidney Failure)
eGFR: Less than 15 mL/min/1.73 m².
At this stage, the kidneys are unable to adequately support the body's needs.
Some patients require:
-
Dialysis
-
Kidney transplantation
-
Comprehensive supportive medical care
Treatment decisions depend on symptoms, laboratory findings, and overall clinical condition.
Symptoms of Kidney Failure
Symptoms often become more noticeable as kidney disease progresses.
Common symptoms include:
-
Fatigue
-
Weakness
-
Swelling of the feet, ankles, or face
-
Reduced urine output
-
Frequent urination at night
-
Foamy urine
-
Blood in the urine
-
High blood pressure
-
Nausea and vomiting
-
Loss of appetite
-
Muscle cramps
-
Dry or itchy skin
-
Difficulty concentrating
-
Shortness of breath
Some patients remain symptom-free until advanced stages.
Common Causes of Kidney Failure
Kidney failure may result from:
-
Diabetes
-
High blood pressure
-
Chronic glomerulonephritis
-
Polycystic kidney disease
-
Lupus nephritis
-
Recurrent kidney infections
-
Urinary tract obstruction
-
Kidney stones
-
Autoimmune diseases
-
Certain inherited kidney disorders
Managing the underlying cause is essential to slowing disease progression.
How Is Kidney Failure Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a complete kidney evaluation.
Medical History and Physical Examination
The doctor reviews:
-
Symptoms
-
Medical history
-
Current medications
-
Family history
-
Blood pressure
-
Diabetes status
Blood Tests
Investigations may include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Hemoglobin
These tests assess kidney function and detect complications.
Urine Tests
Urine investigations may include:
-
Urinalysis
-
Protein Testing
-
Albumin-to-Creatinine Ratio (ACR)
-
Urine Microscopy
Protein in the urine is an important marker of kidney damage.
Imaging Studies
Depending on the patient's condition, investigations may include:
-
Kidney Ultrasound
-
CT Scan
-
MRI when clinically indicated
Imaging helps identify kidney stones, cysts, urinary obstruction, or structural abnormalities.
Kidney Biopsy
In selected cases, a kidney biopsy may be recommended to identify the exact cause of kidney disease.
Treatment for Kidney Failure
Treatment depends on the stage of kidney disease and its underlying cause.
Blood Pressure Control
Maintaining healthy blood pressure helps preserve kidney function.
Diabetes Management
Good blood sugar control slows kidney damage in diabetic patients.
Medications
Your nephrologist may prescribe medications to:
-
Control blood pressure
-
Reduce protein loss in urine
-
Treat anemia
-
Correct electrolyte imbalances
-
Reduce swelling
-
Support bone and mineral health
Treatment is individualized for each patient.
Kidney-Friendly Diet
A personalized diet may include:
-
Reduced salt intake
-
Appropriate protein intake
-
Limiting processed foods
-
Managing potassium and phosphorus when required
Diet recommendations depend on the stage of kidney disease.
Dialysis
When kidney failure becomes advanced and symptoms indicate the kidneys can no longer adequately support the body, dialysis may be recommended.
Dialysis removes waste products and excess fluid from the blood.
Kidney Transplant
Suitable patients with end-stage kidney disease may benefit from kidney transplantation after a comprehensive evaluation.
Transplantation often provides improved long-term quality of life compared with long-term dialysis.
How to Protect Your Kidneys
Healthy habits can help slow kidney disease progression.
Recommendations include:
-
Control diabetes and blood pressure.
-
Follow a kidney-friendly diet.
-
Maintain a healthy weight.
-
Exercise regularly.
-
Avoid smoking.
-
Limit alcohol intake.
-
Stay hydrated according to medical advice.
-
Avoid unnecessary pain-relieving medications.
-
Attend regular nephrology follow-up appointments.
Early intervention is the best way to preserve kidney function.

Frequently Asked Questions (FAQs)
What is the final level of kidney failure?
Stage 5 chronic kidney disease is considered kidney failure, where kidney function is severely reduced and kidney replacement therapy may become necessary.
Does a high creatinine level always mean kidney failure?
No. A high creatinine level indicates reduced kidney filtration but does not automatically mean kidney failure. Doctors evaluate eGFR, urine tests, imaging, and other clinical findings.
Can kidney disease stop progressing?
In many cases, early treatment and lifestyle changes can significantly slow disease progression, although chronic kidney disease is usually not completely reversible.
When should I consult a nephrologist?
You should seek medical evaluation if you have high creatinine levels, reduced eGFR, swelling, protein or blood in the urine, diabetes, high blood pressure, or symptoms of kidney disease.
Conclusion
Understanding kidney failure levels helps patients recognize the progression of chronic kidney disease and the importance of timely medical care. Kidney function is primarily assessed using eGFR, along with creatinine levels, urine tests, and other investigations. Early diagnosis, regular monitoring, medications, dietary changes, and management of underlying conditions can slow disease progression and improve quality of life. When kidney function becomes severely impaired, dialysis or kidney transplantation may be considered.
