Chronic renal failure is an older term often used to describe significant long-term reduction in kidney function. Today, doctors generally use the term Stage 3 Chronic Kidney Disease.
Stage 3 is categorized according to estimated glomerular filtration rate (eGFR):
-
Stage 3A: eGFR approximately 45–59 mL/min/1.73 m²
-
Stage 3B: eGFR approximately 30–44 mL/min/1.73 m²
For CKD to be diagnosed, kidney abnormalities generally need to persist for at least three months.
A single low eGFR result does not necessarily establish chronic kidney disease. Repeat testing and assessment of urine protein or albumin may be required.
Is Stage 3 Kidney Disease the Same as Kidney Failure?
Not exactly.
Stage 3 CKD indicates a moderate reduction in kidney function. It is not the same as complete kidney failure or end-stage kidney disease.
Kidney failure is generally associated with Stage 5 CKD, particularly when eGFR is below 15 mL/min/1.73 m² and kidney function is severely impaired.
However, Stage 3 is an important point at which specialist care can help reduce the risk of further deterioration.
Symptoms of Chronic Renal Failure Stage 3
Some patients with Stage 3 CKD have no noticeable symptoms.
When symptoms occur, they may include:
Tiredness and Weakness
Reduced kidney function may contribute to anemia and the buildup of waste products, resulting in fatigue or reduced stamina.
Swelling
Fluid retention can cause swelling around the:
-
Feet
-
Ankles
-
Legs
-
Hands
-
Face
Changes in Urination
Some patients may experience:
-
Increased urination
-
Night-time urination
-
Foamy urine
-
Blood in the urine
-
Changes in urine volume
High Blood Pressure
Hypertension can both contribute to kidney damage and become more difficult to control as CKD progresses.
Muscle Cramps
Changes in fluid and electrolyte balance may contribute to muscle cramps.
Itchy or Dry Skin
Some patients with reduced kidney function may experience dry or itchy skin, although persistent itching is more common in advanced kidney disease.
Poor Appetite or Nausea
More significant accumulation of waste products may cause appetite changes or nausea.
Symptoms vary considerably between individuals, and some patients remain symptom-free despite abnormal kidney tests.
Common Causes of Stage 3 Chronic Renal Failure
Several conditions can cause or contribute to Stage 3 CKD.
Diabetes
Long-standing or poorly controlled diabetes can damage the kidney's filtering units and cause albumin to leak into the urine.
High Blood Pressure
Chronic hypertension can damage blood vessels within the kidneys and gradually reduce kidney function.
Glomerular Diseases
Conditions affecting the kidney's filtering units, such as glomerulonephritis, can cause progressive renal impairment.
Polycystic Kidney Disease
Inherited cystic kidney disorders can gradually reduce kidney function.
Recurrent Kidney Infections
Repeated or severe kidney infections may cause permanent scarring in some patients.
Kidney Stones or Urinary Obstruction
Repeated obstruction or significant urinary tract abnormalities can damage kidney tissue over time.
Autoimmune Kidney Diseases
Diseases such as lupus can affect the kidneys and lead to chronic kidney damage.
Previous Acute Kidney Injury
An episode of severe acute kidney injury may sometimes result in incomplete recovery and leave persistent kidney impairment.
Who Is at Higher Risk of Stage 3 CKD?
Risk may be increased in people with:
-
Diabetes
-
High blood pressure
-
Heart disease
-
Obesity
-
Family history of kidney disease
-
Previous acute kidney injury
-
Recurrent kidney stones
-
Autoimmune diseases
-
Older age
People in higher-risk groups may benefit from periodic kidney function and urine testing.
How Is Chronic Renal Failure Stage 3 Diagnosed?
Diagnosis requires more than a single blood test.
At Prabhakar Bhurke Clinic, a super specialist nephrologist may evaluate kidney health using several investigations.
Serum Creatinine and eGFR
Creatinine is used to estimate kidney filtration through the eGFR calculation.
The eGFR helps determine the stage of CKD and monitor changes over time.
Urine Albumin Testing
Urine albumin-to-creatinine ratio (ACR) helps determine whether protein is leaking through the kidney's filtering system.
The combination of eGFR and albuminuria provides important information about kidney disease risk.
Blood Tests
Additional tests may include:
-
Blood urea nitrogen
-
Electrolytes
-
Hemoglobin
-
Blood glucose
-
Calcium
-
Phosphorus
-
Other tests depending on the patient's condition
Blood Pressure Assessment
Blood pressure monitoring is an important part of CKD evaluation and treatment.
Kidney Ultrasound
Ultrasound may help assess:
-
Kidney size
-
Structural abnormalities
-
Cysts
-
Stones
-
Urinary obstruction
Additional Investigations
Depending on the suspected cause, the nephrologist may recommend autoimmune tests, specialized laboratory investigations, or a kidney biopsy.
Treatment for Chronic Renal Failure Stage 3
The main goal of treatment is to preserve kidney function and reduce the risk of progression.
Treatment varies depending on the cause, eGFR, urine albumin levels, blood pressure, diabetes status, medications, and other health conditions.
Control Blood Pressure
Maintaining an appropriate blood pressure is one of the most important aspects of kidney protection.
Certain blood-pressure medicines may also reduce protein leakage in the urine when appropriate.
Manage Diabetes
Good diabetes management can help reduce ongoing kidney damage.
Depending on the individual patient, the nephrologist may consider kidney-protective medications in addition to glucose-lowering treatment.
Reduce Protein Loss in Urine
Patients with albuminuria may benefit from medications that reduce pressure within the kidney's filtering system.
Treatment should be selected according to the patient's kidney function, potassium level, blood pressure, and other medical factors.
Manage Cholesterol and Cardiovascular Risk
CKD is associated with increased cardiovascular risk. Managing cholesterol and other cardiovascular risk factors is therefore an important part of long-term treatment.
Treat Anemia
Some Stage 3 CKD patients develop anemia.
If anemia is present, the doctor may investigate causes such as iron deficiency and determine appropriate treatment.
Manage Mineral and Electrolyte Problems
Calcium, phosphorus, potassium, and acid-base status may require monitoring depending on kidney function and other clinical factors.
Avoid Kidney-Harming Medicines
Certain medicines, particularly unnecessary or frequent use of NSAID painkillers, can worsen kidney function in susceptible individuals.
Always discuss regular medication use with your doctor.
Diet for Stage 3 Chronic Renal Failure
There is no single kidney diet that is appropriate for everyone with Stage 3 CKD.
Dietary recommendations depend on:
-
Kidney function
-
Urine protein levels
-
Potassium level
-
Phosphorus level
-
Blood pressure
-
Diabetes
-
Nutritional status
General principles may include:
-
Limiting excessive salt intake
-
Avoiding highly processed foods
-
Maintaining an appropriate protein intake
-
Eating a balanced diet
-
Managing blood sugar
-
Maintaining a healthy body weight
Potassium and phosphorus should not be restricted automatically. Restrictions should be based on laboratory results and individual medical advice.
Fluid intake should also be individualized rather than increased or restricted without a reason.
Can Chronic Renal Failure Stage 3 Be Reversed?
Chronic kidney disease is generally considered a long-term condition and established kidney damage may not be completely reversible.
However, kidney function can sometimes remain stable for many years, and appropriate treatment may slow progression significantly.
If a reduced eGFR is caused partly by a reversible factor, such as dehydration or an acute illness, kidney function may improve after the underlying problem is treated.
The prognosis depends on the cause of CKD, eGFR trend, albuminuria, blood pressure, diabetes control, and other health factors.
Can Stage 3 CKD Progress to Kidney Failure?
It can, but progression is not inevitable.
Some patients remain stable at Stage 3 for a long period, while others experience faster progression.
Factors associated with higher risk may include:
-
Persistent significant albuminuria
-
Poorly controlled blood pressure
-
Poorly controlled diabetes
-
Continued exposure to kidney injury
-
Certain progressive kidney diseases
-
Recurrent acute kidney injury
Regular monitoring allows doctors to identify changes early and adjust treatment.
Does Stage 3 CKD Require Dialysis?
Usually, no.
Dialysis is generally considered when kidney function becomes severely impaired and the patient develops complications that cannot be adequately managed through other treatment.
Dialysis decisions are based on the overall clinical condition rather than an eGFR number alone.
Most patients with Stage 3 CKD are managed with medications, lifestyle changes, monitoring, and treatment of the underlying cause rather than dialysis.
How to Protect Kidney Function in Stage 3
Patients can support long-term kidney health by:
-
Taking prescribed medications consistently
-
Monitoring blood pressure
-
Managing diabetes
-
Reducing excessive salt intake
-
Maintaining a healthy body weight
-
Exercising regularly as medically appropriate
-
Avoiding unnecessary NSAID painkillers
-
Avoiding smoking
-
Following recommended laboratory testing
-
Keeping regular nephrology appointments
Do not make major dietary or fluid changes without discussing them with your healthcare professional.
Monitoring Stage 3 Chronic Kidney Disease
Regular follow-up helps assess whether kidney function is stable or changing.
Monitoring may include:
-
eGFR
-
Serum creatinine
-
Urine ACR or protein testing
-
Blood pressure
-
Potassium
-
Hemoglobin
-
Other tests based on individual risk
The frequency of testing depends on kidney function, albuminuria, the underlying disease, and the treatment plan.
When Should You See a Nephrologist?
A nephrology consultation is particularly important if you have:
-
Persistent eGFR below 60
-
High creatinine levels
-
Protein or albumin in the urine
-
Blood in the urine
-
Difficult-to-control hypertension
-
Diabetes with kidney abnormalities
-
Recurrent kidney stones
-
Repeated kidney infections
-
Rapidly changing kidney function
-
Swelling or reduced urine output
Early specialist involvement can help identify the cause and develop an individualized kidney-protection strategy.

Frequently Asked Questions
What does chronic renal failure stage 3 mean?
It generally refers to Stage 3 chronic kidney disease, where eGFR is between approximately 30 and 59 mL/min/1.73 m², divided into Stage 3A and Stage 3B. The condition must generally persist for at least three months to be considered chronic.
Is Stage 3 kidney disease serious?
Stage 3 CKD is an important health condition because kidney function is moderately reduced. However, it does not mean that the kidneys have stopped working, and many patients can remain stable with appropriate treatment and monitoring.
What is the difference between Stage 3A and Stage 3B?
Stage 3A generally has an eGFR of 45–59, while Stage 3B has an eGFR of 30–44. Stage 3B represents a greater reduction in kidney filtration and may require closer monitoring depending on the patient's overall risk.
Will I need dialysis in Stage 3?
Usually not. Most Stage 3 patients do not require dialysis. Dialysis is generally reserved for advanced kidney failure with appropriate clinical indications.
Can Stage 3 CKD improve?
If kidney function is temporarily reduced because of an acute or reversible problem, eGFR may improve after treatment. Established chronic kidney damage is generally not fully reversible, but progression can often be slowed.
What should I eat with Stage 3 CKD?
Diet should be individualized. Many patients benefit from limiting excessive sodium and highly processed foods while maintaining appropriate protein intake. Potassium, phosphorus, fluids, and protein should be adjusted according to laboratory results and medical advice.
How often should kidney function be checked?
The appropriate frequency varies according to eGFR, urine albumin levels, the underlying kidney disease, and treatment. Your nephrologist can establish an appropriate monitoring schedule.
Which doctor treats Stage 3 chronic renal failure?
A nephrologist specializes in diagnosing and managing chronic kidney disease, including Stage 3 CKD, its complications, and strategies to protect remaining kidney function.
Conclusion
Chronic renal failure stage 3 generally describes Stage 3 chronic kidney disease, a condition characterized by a moderate reduction in kidney filtration. It does not mean that the kidneys have completely failed or that dialysis is immediately necessary.
Because Stage 3 CKD may progress silently, regular monitoring of eGFR, urine albumin, blood pressure, and other relevant health markers is important. Controlling diabetes and hypertension, treating the underlying kidney disease, following an individualized diet, and avoiding unnecessary kidney-harming medicines can help protect kidney function.
