3rd stage kidney disease, commonly called stage 3 chronic kidney disease (CKD), means that kidney function is moderately reduced.

Doctors classify CKD primarily using the estimated glomerular filtration rate (eGFR) along with evidence of kidney damage and how long the abnormality has been present.

Stage 3 CKD is generally divided into:

• Stage 3A: eGFR 45 to 59 mL/min/1.73 m²

• Stage 3B: eGFR 30 to 44 mL/min/1.73 m²

Stage 3 does not automatically mean kidney failure or dialysis.

Many people with stage 3 kidney disease can remain stable for years when the underlying cause and major risk factors are appropriately managed.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and management for patients with chronic kidney disease.

What Causes Stage 3 Kidney Disease?

Stage 3 CKD can develop from several underlying conditions.

Common causes include:

• Diabetes

• High blood pressure

• Glomerular kidney diseases

• Recurrent kidney infections

• Long-standing urinary obstruction

• Polycystic kidney disease

• Certain inherited kidney disorders

• Previous episodes of acute kidney injury

• Other chronic kidney conditions

Identifying the cause is important because treatment can differ considerably from one patient to another.

What Is the eGFR in 3rd Stage Kidney Disease?

eGFR is one of the main measurements used to classify CKD.

CKD Stage	eGFR
Stage 1	90 or higher with evidence of kidney damage
Stage 2	60 to 89 with evidence of kidney damage
Stage 3A	45 to 59
Stage 3B	30 to 44
Stage 4	15 to 29
Stage 5	Less than 15

A single eGFR result should not automatically be interpreted as chronic kidney disease. Doctors consider whether reduced kidney function persists and review other findings such as urine albumin.

What Creatinine Level Is Seen in Stage 3 Kidney Disease?

There is no single creatinine value that defines stage 3 CKD.

Creatinine varies according to factors such as:

• Age

• Sex

• Muscle mass

• Diet

• Hydration

• Certain medications

• Overall health

Two people with the same creatinine level can have different eGFR values.

Therefore, doctors generally use creatinine as part of an eGFR calculation rather than using creatinine alone to determine the CKD stage.

What Are the Symptoms of 3rd Stage Kidney Disease?

Stage 3 kidney disease may produce few noticeable symptoms.

Some people may experience:

• Tiredness

• Swelling around the ankles or feet

• Changes in urination

• Foamy urine

• Increased or decreased urine frequency

• Muscle cramps

• Dry or itchy skin

• Reduced appetite

• Sleep disturbances

• High blood pressure

However, these symptoms are not specific to CKD.

Some patients with stage 3 disease feel completely well, which is why routine kidney-function testing can be important for people at increased risk.

Can Stage 3 Kidney Disease Cause Swelling?

Yes, swelling can occur when kidney disease contributes to fluid retention or significant protein loss through the urine.

Swelling may appear around:

• Ankles

• Feet

• Legs

• Hands

• Face or eyelids

New or rapidly worsening swelling should be medically evaluated because it can also occur with heart, liver, medication-related and other conditions.

Is Stage 3 Kidney Disease Serious?

Stage 3 CKD should be taken seriously because it indicates a meaningful reduction in kidney function.

However, it does not mean that kidney failure is inevitable.

The future course varies between individuals.

Factors that can influence progression include:

• Underlying kidney disease

• Blood pressure control

• Diabetes control

• Urine albumin levels

• Rate of eGFR decline

• Smoking

• Cardiovascular health

• Medication use

• Episodes of acute kidney injury

Regular monitoring allows changes in kidney function to be identified earlier.

Can 3rd Stage Kidney Disease Be Reversed?

Whether kidney function can improve depends on the underlying cause.

Some temporary factors can cause kidney function to worsen and subsequently improve.

For example, an episode of dehydration or acute illness may temporarily reduce kidney function.

However, established chronic kidney damage or scarring generally cannot simply be reversed.

The aim of treatment is therefore to:

• Identify the cause

• Protect remaining kidney function

• Reduce factors that accelerate progression

• Treat complications

• Monitor kidney function over time

Treatment for 3rd Stage Kidney Disease

There is no single medicine that treats every case of stage 3 CKD.

Treatment is based on the cause and the patient's individual risk profile.

Control Blood Pressure

High blood pressure can contribute to kidney damage and accelerate CKD progression.

Appropriate blood-pressure treatment may help protect kidney function.

Manage Diabetes

For patients with diabetes, individualized glucose management is an important part of kidney protection.

Doctors may also monitor urine albumin and eGFR regularly.

Reduce Excess Albumin in Urine

Patients with significant albuminuria may benefit from specific kidney-protective treatments when medically appropriate.

Medication choice depends on kidney function, potassium levels, blood pressure and other factors.

Treat Underlying Kidney Disease

Some kidney diseases require disease-specific treatment.

The treatment may involve medicines that control inflammation, immune activity or other mechanisms depending on the diagnosis.

Manage CKD Complications

Doctors may monitor for:

• Anemia

• Electrolyte abnormalities

• Acid-base disturbances

• Mineral and bone abnormalities

• Fluid retention

• Cardiovascular risk

Not every patient develops these complications.

What Diet Is Recommended for Stage 3 Kidney Disease?

There is no single diet suitable for every person with stage 3 CKD.

Dietary recommendations may depend on:

• Potassium level

• Phosphorus level

• Urine protein

• Blood pressure

• Diabetes

• Body weight

• Other medical conditions

A healthcare professional or renal dietitian may recommend adjustments involving:

• Sodium

• Protein

• Potassium

• Phosphorus

• Fluid intake

Avoid extreme dietary restrictions without professional guidance.

How Much Water Should You Drink With Stage 3 CKD?

Fluid requirements are individualized.

Some people with stage 3 CKD can drink fluids normally, while others may require restrictions because of fluid retention or other medical conditions.

Therefore, drinking very large quantities of water is not a treatment for CKD.

Follow the fluid recommendation provided by your healthcare professional.

What Tests Are Important in Stage 3 CKD?

Regular monitoring may include:

Kidney Function

• Serum creatinine

• eGFR

• Blood urea

Urine Testing

• Urine albumin

• Urine protein

• Blood in urine

• Other abnormalities

Blood Tests

Depending on the patient's condition, doctors may monitor:

• Potassium

• Sodium

• Bicarbonate

• Hemoglobin

• Calcium

• Phosphorus

• Blood glucose

The frequency of testing depends on disease severity, stability and individual risk.

Can Stage 3 CKD Progress to Stage 4?

It can, but progression is not inevitable.

Some patients remain stable for long periods, while others experience gradual loss of kidney function.

A significant decline in eGFR over time deserves investigation.

The goal of treatment is to identify modifiable risk factors and slow progression wherever possible.

How Can You Protect Kidney Function in Stage 3?

Practical measures may include:

• Keep blood pressure within the target recommended by your doctor.

• Manage diabetes appropriately.

• Take prescribed medicines as directed.

• Avoid unnecessary NSAID painkillers.

• Avoid unverified herbal kidney remedies.

• Limit excessive dietary salt.

• Maintain an appropriate body weight.

• Stay physically active according to your health status.

• Avoid smoking.

• Attend scheduled kidney-function tests.

• Follow an individualized dietary plan.

Can Someone With Stage 3 Kidney Disease Live a Normal Life?

Many people with stage 3 CKD continue working, exercising and participating in normal daily activities.

The impact of CKD varies according to kidney function, symptoms, underlying disease and other health conditions.

Regular follow-up is important because CKD can change over time even when a person feels well.

Does Stage 3 Kidney Disease Require Dialysis?

Usually, no.

Dialysis is not prescribed simply because someone has stage 3 CKD.

Dialysis is generally considered when kidney failure becomes advanced and the kidneys can no longer adequately maintain the body's internal balance, particularly when serious complications cannot be controlled with medical treatment.

Stage 3 CKD is therefore generally managed with medical treatment, monitoring and risk-factor control rather than routine dialysis.

When Should You See a Nephrologist?

Specialist kidney evaluation may be appropriate when there is:

• Persistent reduction in eGFR

• Increasing creatinine

• Significant albumin or protein in urine

• Rapid decline in kidney function

• Difficult-to-control blood pressure

• Recurrent acute kidney injury

• Electrolyte abnormalities

• Unexplained blood in urine

• Suspected advanced kidney disease

A nephrologist can help determine the cause of CKD and create an individualized management plan.

Warning Signs That Need Prompt Medical Attention

Seek urgent medical care if stage 3 CKD is accompanied by:

• Very little or no urine

• Severe breathlessness

• Chest pain

• Confusion

• Persistent vomiting

• Rapidly worsening swelling

• Severe weakness

• Sudden deterioration in health

These symptoms can have several causes and may indicate a serious complication.

Frequently Asked Questions

What does 3rd stage kidney disease mean?

It generally refers to stage 3 chronic kidney disease, where eGFR is between 30 and 59 mL/min/1.73 m², divided into stage 3A and stage 3B.

Is stage 3 kidney disease the same as kidney failure?

No. Stage 3 CKD represents moderate reduction in kidney function. Kidney failure is generally associated with much more advanced loss of kidney function.

What creatinine level means stage 3 CKD?

There is no fixed creatinine number. Doctors use eGFR, calculated partly from creatinine, along with other clinical information.

Can stage 3 kidney disease be cured?

Established chronic kidney damage usually cannot simply be cured, but appropriate treatment may slow progression and manage complications. Some reversible factors can temporarily worsen kidney function and then improve.

Does stage 3 CKD require dialysis?

No. Most people with stage 3 CKD do not require dialysis solely because of their CKD stage.

What should I avoid with stage 3 kidney disease?

Avoid unnecessary NSAID painkillers, unverified supplements and extreme diets. Specific dietary and medication restrictions should be based on your kidney function and laboratory results.

Conclusion

3rd stage kidney disease is a significant but manageable stage of chronic kidney disease. It is divided into stage 3A and stage 3B according to eGFR.

An elevated creatinine level alone does not determine the CKD stage. Doctors consider eGFR, urine albumin, previous results, the underlying cause and the overall clinical picture.

Stage 3 CKD does not automatically mean dialysis or kidney failure. With appropriate medical management, blood-pressure and diabetes control, individualized dietary guidance and regular monitoring, progression may be slowed in many patients.

If you have been diagnosed with stage 3 CKD or have persistently abnormal kidney-function tests, specialist evaluation can help identify the cause and establish an appropriate long-term treatment plan.
