The term stage 2 renal disease is commonly used to describe an early category of chronic kidney disease associated with an eGFR of 60 to 89 mL/min/1.73 m².

However, an important clarification is needed: an eGFR between 60 and 89 does not by itself establish chronic kidney disease.

For a person to be classified as having CKD in the G2 range, there generally needs to be evidence of kidney damage that persists for at least three months. Examples include albumin in the urine or certain structural or other kidney abnormalities.

This distinction is important because some otherwise healthy people may have an eGFR in this range without having CKD.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation of abnormal kidney-function results and early kidney disease.

What Does an eGFR of 60 to 89 Mean?

eGFR is an estimate of how effectively the kidneys filter blood.

The G2 kidney-function category is defined as:

eGFR: 60–89 mL/min/1.73 m²

It is described as mildly decreased GFR in the CKD classification system.

But the number needs context.

For example:

• eGFR 85 with no evidence of kidney damage does not automatically mean CKD.

• eGFR 75 with persistent albuminuria may meet CKD criteria.

• A temporary reduction during an acute illness may not represent established chronic disease.

• A changing eGFR needs to be interpreted alongside previous results.

Therefore, one laboratory report should not be used in isolation to label someone with stage 2 kidney disease.

Stage 2 Renal Disease vs Stage 2 Renal Failure

These terms are sometimes used interchangeably online, but they are not medically equivalent.

Stage 2 CKD represents an early category of chronic kidney disease when appropriate evidence of kidney damage is present.

It is not the same as kidney failure.

Kidney failure is classified in the G5 range, where eGFR is below 15 mL/min/1.73 m², although dialysis decisions depend on the patient's overall clinical condition rather than an eGFR number alone.

Therefore, a diagnosis of stage 2 CKD does not mean that dialysis is required or that the kidneys are close to stopping.

What Can Cause Stage 2 Kidney Disease?

Many conditions can cause or contribute to early chronic kidney damage.

Diabetes

Persistently high blood glucose can damage the small blood vessels and filtering structures within the kidneys.

Diabetic kidney disease often develops gradually, making regular kidney testing important for people with diabetes.

High Blood Pressure

Long-term hypertension can damage kidney blood vessels and contribute to declining kidney function.

At the same time, kidney disease itself can contribute to elevated blood pressure.

Protein or Albumin in Urine

Persistent albuminuria can indicate damage to the kidney's filtration barrier.

A urine albumin-to-creatinine ratio, or UACR, is commonly used to assess urinary albumin.

Glomerular Diseases

Conditions affecting the kidney's filtering units can produce:

• Proteinuria

• Blood in urine

• High blood pressure

• Reduced kidney function

Recurrent Kidney Stones or Obstruction

Repeated obstruction or complicated urinary tract conditions can contribute to kidney damage in some patients.

Inherited Kidney Disorders

Certain inherited diseases can gradually affect kidney structure and function.

Previous Kidney Injury

An episode of acute kidney injury may sometimes leave persistent kidney damage.

The cause needs to be identified because treatment varies substantially between different kidney diseases.

Are There Symptoms in Stage 2 Kidney Disease?

Often, there may be no obvious symptoms.

Early CKD can remain silent, which is one reason kidney disease may be discovered during blood or urine testing performed for another reason. NIDDK notes that testing may be the only way to identify kidney disease in some people.

Possible findings can include:

• Protein or albumin in urine

• Blood in urine

• High blood pressure

• Mild changes in kidney-function tests

• Changes related to the underlying disease

Symptoms such as significant swelling, severe fatigue, nausea or breathlessness are more commonly associated with more advanced kidney dysfunction or other complications and should not automatically be attributed to stage 2 disease.

Can Stage 2 Kidney Disease Cause Back Pain?

Usually, mild CKD itself does not cause typical kidney pain.

Back or flank pain may instead be related to another condition, such as:

• Kidney stones

• Urinary obstruction

• Kidney infection

• Cysts

• Musculoskeletal problems

If someone with an abnormal kidney-function test develops significant flank pain, fever, blood in urine or urinary symptoms, further evaluation may be appropriate.

How Is Stage 2 Renal Disease Diagnosed?

Diagnosis involves more than checking creatinine once.

1. Serum Creatinine and eGFR

Blood creatinine is used to estimate kidney filtration.

eGFR is an estimate rather than a direct measurement of kidney function, and trends over time can be more informative than a single value.

2. Urine Albumin Testing

A urine albumin-to-creatinine ratio can identify albumin leakage.

Persistent albuminuria can be an important marker of kidney damage and helps with risk assessment.

3. Urinalysis

A routine urine examination may detect:

• Blood

• Protein

• Infection

• Other abnormalities

4. Blood Pressure Measurement

Blood pressure is an important part of kidney assessment because uncontrolled hypertension can contribute to kidney damage.

5. Imaging

Ultrasound or other imaging may be recommended when structural abnormalities, obstruction, stones or other conditions are suspected.

6. Additional Testing

Depending on the suspected cause, a nephrologist may recommend additional blood tests, autoimmune testing, genetic evaluation or kidney biopsy.

Not every patient needs all of these investigations.

Why Is UACR Important in Stage 2 CKD?

An eGFR between 60 and 89 tells only part of the story.

The amount of albumin in urine can provide additional information about kidney damage and future risk.

A person with mildly reduced eGFR and persistent albuminuria may require closer assessment than someone with a similar eGFR but no evidence of kidney damage.

This is why modern CKD assessment considers both GFR and albuminuria, along with the underlying cause and other clinical factors.

What Is the Treatment for Stage 2 Renal Disease?

There is no universal tablet that treats every case of stage 2 CKD.

Treatment is directed toward the underlying cause and modifiable risk factors.

Control Blood Pressure

Keeping blood pressure within the target recommended by the treating clinician can help protect kidney and cardiovascular health.

Some medications have additional kidney-protective benefits in selected patients.

Manage Diabetes

For people with diabetes, appropriate blood-glucose management is an important part of reducing further kidney damage.

Reduce Significant Albuminuria

When albuminuria is present, certain kidney-protective medicines may be appropriate depending on the patient's diagnosis, blood pressure, potassium level and other factors.

Review Medicines

Some medicines can affect kidney function or require dose adjustments when kidney function changes.

Do not stop prescribed medicines without discussing them with your doctor.

Manage Cholesterol and Cardiovascular Risk

Kidney disease and cardiovascular disease are closely connected. Overall cardiovascular risk should therefore be addressed as part of long-term kidney care.

Treat the Specific Kidney Disease

Glomerular disease, recurrent stones, obstruction, autoimmune disease and inherited kidney disorders may each require different treatment strategies.

Can Stage 2 Renal Disease Be Reversed?

It depends on what caused the abnormal kidney findings.

If a reversible factor is contributing to reduced kidney function, correcting it may improve kidney measurements.

However, established chronic kidney damage or scarring cannot always be completely reversed.

The goal is often to:

• Identify the cause

• Treat reversible contributors

• Reduce ongoing kidney injury

• Control blood pressure and diabetes

• Reduce significant albuminuria when appropriate

• Monitor kidney function over time

An early diagnosis can provide an opportunity to address risk factors before more substantial kidney-function loss occurs.

Does Stage 2 CKD Progress to Kidney Failure?

Not necessarily.

Many people with early CKD do not progress to kidney failure.

The likelihood of progression depends on factors such as:

• Underlying cause

• eGFR trend

• Albuminuria

• Diabetes

• Blood-pressure control

• Cardiovascular disease

• Recurrent acute kidney injury

• Other medical conditions

NIDDK notes that some people with CKD progress more rapidly while others never develop kidney failure. Monitoring progression helps identify people at higher risk.

How Can You Protect Kidney Function at Stage 2?

Early kidney disease is an important time to establish long-term kidney-protection habits.

Keep Blood Pressure Controlled

Follow the blood-pressure target recommended by your healthcare professional.

Manage Blood Sugar

If you have diabetes, follow your individualized diabetes-management plan.

Avoid Unnecessary NSAID Use

Frequent or inappropriate use of certain painkillers can be harmful to susceptible kidneys.

Ask a doctor or pharmacist before using medicines regularly.

Limit Excess Sodium

Reducing excessive salt intake can support blood-pressure control.

Maintain a Healthy Weight

A healthy weight can benefit blood pressure, metabolic health and cardiovascular health.

Avoid Smoking

Smoking increases cardiovascular and overall health risks.

Stay Appropriately Hydrated

There is no universal requirement to drink excessive amounts of water for CKD. Fluid intake should reflect kidney function, heart health, medications and individual medical advice.

Keep Follow-Up Appointments

Regular testing helps identify changes in kidney function and urine albumin.

What Diet Is Recommended for Stage 2 Renal Disease?

There is no single diet suitable for every person with stage 2 CKD.

Dietary advice may depend on:

• Blood pressure

• Diabetes

• UACR

• Potassium

• Phosphorus

• Body weight

• Nutritional status

• Other medical conditions

A generally heart-healthy eating pattern with appropriate sodium intake may be useful, but unnecessary restriction of protein, potassium or other nutrients can be inappropriate.

A renal dietitian can provide individualized recommendations when needed.

Can You Live a Normal Life With Stage 2 CKD?

Many people with early CKD can continue their usual activities and remain stable for years.

The diagnosis should nevertheless be taken seriously because it provides an opportunity to identify and manage the factors that may contribute to progression.

Regular monitoring of kidney function, urine albumin, blood pressure and the underlying condition can help guide long-term care.

When Should You Consult a Nephrologist?

A kidney specialist may be appropriate when there is:

• Persistent albuminuria

• Repeated abnormal kidney-function results

• Unexplained blood in urine

• Declining eGFR

• Difficult-to-control hypertension

• Recurrent kidney stones or obstruction

• Suspected glomerular disease

• A family history of significant kidney disease

• An unexplained change in creatinine

A nephrologist can help determine whether an eGFR in the 60–89 range represents CKD and identify the cause when kidney damage is present.

Frequently Asked Questions

What does stage 2 renal disease mean?

Stage 2 generally corresponds to G2 kidney function, with an eGFR of 60–89 mL/min/1.73 m². To diagnose CKD in this range, there should also be evidence of persistent kidney damage.

Is stage 2 renal disease serious?

It is an early stage of CKD when CKD criteria are met, but it should not be confused with kidney failure. Appropriate evaluation and monitoring can help identify factors associated with progression.

Is stage 2 renal disease the same as kidney failure?

No. Stage 2 CKD is very different from kidney failure. Kidney failure corresponds to G5, generally with eGFR below 15 mL/min/1.73 m².

Can stage 2 CKD be cured?

Established chronic kidney damage may not be completely reversible. However, treating the underlying cause and controlling risk factors can help preserve kidney function.

Does stage 2 CKD require dialysis?

No. Stage 2 CKD does not normally require dialysis. Dialysis is considered in advanced kidney failure when clinically indicated.

What should I do if my eGFR is 60 to 89?

An eGFR in this range should be interpreted alongside urine albumin, previous kidney-function results and other evidence of kidney damage. An eGFR of 60–89 alone does not necessarily mean that you have CKD.

Can stage 2 kidney disease get worse?

It can, but progression is not inevitable. The underlying cause, albuminuria, diabetes, blood pressure and changes in eGFR over time influence risk.

Conclusion

Stage 2 renal disease generally refers to the G2 kidney-function category, where eGFR is between 60 and 89 mL/min/1.73 m². However, an eGFR in this range alone does not establish chronic kidney disease. Persistent evidence of kidney damage is also important when making the diagnosis.

Because early CKD may produce few noticeable symptoms, urine albumin testing, blood pressure assessment and monitoring of kidney-function trends can be valuable.

When stage 2 CKD is confirmed, treatment focuses on identifying its cause, managing conditions such as diabetes and hypertension, reducing relevant kidney risks and protecting kidney function over time.
