Being told that you have stage 1 kidney disease can be confusing, particularly when your kidney filtration rate appears normal. The important distinction is that stage 1 chronic kidney disease generally means the kidneys are filtering at a relatively preserved level, but there is evidence of kidney damage or another persistent kidney abnormality.

Because early kidney disease may produce few noticeable symptoms, it is often discovered during routine blood tests, urine testing, health screenings or investigations for another medical condition.

Recognizing the condition early gives patients an opportunity to identify the underlying cause and take steps to protect kidney function.

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

What Is Stage 1 Kidney Disease?

Stage 1 kidney disease generally corresponds to G1 CKD, where the eGFR is 90 mL/min/1.73 m² or higher, together with evidence of kidney damage that persists for at least three months.

Evidence of kidney damage can include:

• Persistent albumin in urine

• Other abnormalities in urine

• Structural kidney abnormalities on imaging

• Certain pathological findings

• Specific established kidney disorders

An eGFR of 90 or above does not automatically mean a person has stage 1 CKD. Evidence of kidney damage is also required.

What Is eGFR?

The estimated glomerular filtration rate, or eGFR, estimates how efficiently the kidneys filter waste from the blood.

The broad G categories are:

• G1: 90 or higher

• G2: 60–89

• G3a: 45–59

• G3b: 30–44

• G4: 15–29

• G5: Less than 15

Doctors interpret eGFR alongside urine findings, medical history and other investigations rather than using one number in isolation.

What Causes Stage 1 Kidney Disease?

Several conditions can cause early kidney damage.

Common causes include:

Diabetes

Long-term high blood glucose can damage the tiny blood vessels and filtering structures within the kidneys.

High Blood Pressure

Uncontrolled hypertension can damage kidney blood vessels and contribute to progressive CKD.

Glomerular Diseases

Diseases affecting the kidney's filtering units can cause protein or blood to appear in urine.

Polycystic Kidney Disease

Inherited cystic disorders can gradually affect kidney structure and function.

Kidney Stones

Repeated stones or urinary obstruction may contribute to kidney damage in some patients.

Recurrent Urinary Infections

Repeated or complicated infections can sometimes affect kidney health.

Congenital Kidney Abnormalities

Some people are born with structural abnormalities that increase their long-term kidney risk.

Autoimmune Kidney Disorders

Certain immune-mediated diseases can affect the kidney's filtering units.

What Are the Symptoms of Stage 1 Kidney Disease?

Many people with stage 1 kidney disease have no obvious symptoms.

When symptoms occur, they may include:

• Foamy urine

• Blood in the urine

• Mild swelling

• Increased urination

• Changes in urinary habits

• High blood pressure

These symptoms can have many different causes and cannot establish a CKD diagnosis by themselves.

Protein in Urine: An Important Early Warning

Albuminuria is an important marker of kidney damage.

Healthy kidney filters generally retain albumin in the bloodstream. Damage to the filtering barrier can allow albumin to pass into urine.

A urine albumin-to-creatinine ratio (UACR) is commonly used to assess urine albumin.

Persistent albuminuria can indicate increased kidney and cardiovascular risk even when eGFR remains relatively preserved.

How Is Stage 1 Kidney Disease Diagnosed?

Diagnosis may involve several types of evaluation.

Blood Tests

A healthcare professional may review:

• Serum creatinine

• eGFR

• Electrolytes

• Blood glucose

Urine Testing

Testing may assess:

• Albumin

• Protein

• Blood

• Infection

• Other urinary abnormalities

Blood Pressure Measurement

Blood pressure should be monitored because hypertension is both a cause and consequence of kidney disease.

Kidney Imaging

Ultrasound or other imaging may be recommended if structural abnormalities are suspected.

Does Stage 1 Kidney Disease Mean Kidney Failure?

No.

Stage 1 CKD does not mean that the kidneys are failing.

In this stage, filtration can remain preserved. The diagnosis indicates that there is evidence of chronic kidney damage or another qualifying kidney abnormality.

The focus is on identifying the cause and preventing further damage.

Can Stage 1 Kidney Disease Progress?

Some patients remain stable for many years, while others can experience progression.

Risk is influenced by:

• Albuminuria

• Underlying kidney disease

• Diabetes

• Blood pressure

• Smoking

• Cardiovascular disease

• Episodes of acute kidney injury

• Changes in eGFR over time

A stable kidney function trend is generally more reassuring than a rapidly declining eGFR.

Treatment for Stage 1 Kidney Disease

There is no single medicine that treats every case of stage 1 kidney disease.

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

Manage Blood Pressure

Keeping blood pressure within the range recommended by your doctor can help protect the kidneys.

Control Diabetes

Appropriate blood glucose management is important for people with diabetes.

Manage Albuminuria

Certain kidney-protective medications may be recommended for suitable patients with albuminuria.

Avoid Unnecessary NSAID Use

Some pain medicines, particularly certain non-steroidal anti-inflammatory drugs, can affect kidney function.

Discuss frequent painkiller use with your doctor.

Treat the Underlying Disease

Autoimmune disorders, infections, urinary obstruction and other kidney conditions require condition-specific treatment.

Diet for Stage 1 Kidney Disease

Not everyone with early CKD needs a highly restrictive kidney diet.

General healthy habits may include:

• Limiting excessive sodium

• Eating more minimally processed foods

• Maintaining a healthy body weight

• Avoiding excessive alcohol

• Following an appropriate protein intake

• Staying appropriately hydrated

Specific restrictions on potassium, phosphorus, protein or fluids should be based on medical advice and laboratory results.

Exercise and Stage 1 Kidney Disease

Regular physical activity can support:

• Healthy blood pressure

• Weight management

• Cardiovascular health

• Blood glucose control

Exercise recommendations should be adjusted for individual health conditions.

Can Stage 1 Kidney Disease Be Reversed?

The answer depends on why the kidney abnormality is present.

Some reversible conditions may improve with appropriate treatment.

Established chronic structural damage may persist, but progression can often be reduced by addressing the underlying cause and controlling risk factors.

How Often Should Kidney Function Be Checked?

Monitoring frequency varies according to individual risk.

Your doctor may consider:

• eGFR

• Urine albumin

• Blood pressure

• Diabetes status

• Underlying kidney condition

• Previous changes in kidney function

Patients with greater risk may need more frequent follow-up.

When Should You See a Nephrologist?

Consider specialist kidney evaluation if you have:

• Persistent protein or albumin in urine

• Repeated blood in urine

• Abnormal kidney imaging

• Reduced kidney function

• Diabetes with kidney abnormalities

• Difficult-to-control blood pressure

• Recurrent kidney stones

• Family history of kidney disease

• A known congenital or inherited kidney condition

Frequently Asked Questions

Is stage 1 kidney disease serious?

It is an early form of CKD and should not be ignored. However, stage 1 does not mean kidney failure, and many patients can remain stable with appropriate management.

Can you have stage 1 kidney disease with normal creatinine?

Yes. Kidney damage can exist even when serum creatinine and eGFR appear relatively normal.

Does stage 1 kidney disease require dialysis?

No. Dialysis is not normally required for stage 1 CKD.

Can stage 1 kidney disease go away?

Some reversible kidney abnormalities may improve, while established chronic kidney damage may remain. The outcome depends on the underlying cause.

What is the most important thing to do after diagnosis?

Identify the underlying cause, monitor kidney function and urine albumin, control blood pressure and diabetes when applicable, and follow an individualized kidney-protection plan.

Conclusion

Stage 1 kidney disease is an early stage of chronic kidney disease in which kidney filtration may remain well preserved despite evidence of kidney damage. Because symptoms are often absent, appropriate blood and urine testing is essential.

Early specialist care can help identify the cause, manage risk factors and reduce the likelihood of kidney disease progression.
