Chronic kidney disease stage 1 is the earliest recognized stage of chronic kidney disease. It can be confusing because kidney filtration may still be within the normal or high range, yet there is evidence of kidney damage.

Many people with stage 1 CKD feel completely healthy and may discover the condition only through a routine urine or blood test. This makes early evaluation especially important.

When kidney disease is identified at this stage, appropriate management can help control the underlying cause, reduce the risk of progression and protect kidney health.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and long-term care for patients with kidney disease and kidney-related risk factors.

What Is CKD Stage 1?

CKD stage 1 generally refers to an eGFR of 90 mL/min/1.73 m² or higher together with evidence of kidney damage that has been present for at least three months.

An important point is that:

An eGFR of 90 or above by itself does not mean a person has CKD.

There must also be another marker of kidney damage, such as persistent albumin in the urine or certain structural abnormalities.

What Does eGFR Mean?

Estimated glomerular filtration rate (eGFR) is a calculation used to estimate how effectively the kidneys filter blood.

A simplified CKD classification includes:

• G1: eGFR ≥90

• G2: eGFR 60–89

• G3a: eGFR 45–59

• G3b: eGFR 30–44

• G4: eGFR 15–29

• G5: eGFR <15

The eGFR result should always be interpreted alongside urine findings, medical history and other tests.

What Causes Stage 1 Kidney Disease?

Possible causes include:

• Diabetes

• High blood pressure

• Glomerular diseases

• Polycystic kidney disease

• Recurrent kidney infections

• Kidney stones

• Congenital kidney abnormalities

• Autoimmune kidney disorders

• Family history of kidney disease

The cause matters because treatment should target the underlying condition whenever possible.

Symptoms of Chronic Kidney Disease Stage 1

Most people with stage 1 CKD have no obvious symptoms.

Occasionally, patients may notice:

• Foamy urine

• Blood in the urine

• Mild swelling

• Changes in urination

• High blood pressure

These symptoms are not specific to CKD, so laboratory testing is essential.

Protein in Urine and Stage 1 CKD

One of the most important findings in early kidney disease is albuminuria.

Healthy kidneys generally prevent significant amounts of albumin from passing into the urine. When kidney filters are damaged, albumin can leak into the urine.

A urine albumin-to-creatinine ratio (UACR) can help detect this problem.

Persistent albuminuria can be an important indicator of kidney and cardiovascular risk.

Can Stage 1 CKD Be Reversed?

It depends on the underlying cause.

Some kidney abnormalities or reversible factors can improve with appropriate treatment.

However, when structural or chronic kidney damage is established, the goal is generally to:

• Protect remaining kidney function

• Treat the underlying cause

• Reduce albuminuria when appropriate

• Control blood pressure

• Manage diabetes

• Reduce cardiovascular risk

• Prevent further kidney injury

Treatment for CKD Stage 1

Treatment is individualized according to the cause and risk profile.

Control Blood Pressure

Maintaining healthy blood pressure is important for protecting kidney function.

Manage Diabetes

People with diabetes should maintain appropriate blood glucose control and undergo recommended kidney screening.

Reduce Excess Salt

Reducing excessive dietary sodium can help with blood pressure management and overall kidney health.

Treat Albuminuria

Certain medications may reduce albumin leakage and provide kidney protection in appropriate patients.

Avoid Unnecessary Kidney-Harming Medicines

Some medications, including certain painkillers, can affect kidney function.

Discuss regular or over-the-counter medicines with a healthcare professional.

Lifestyle Changes for Stage 1 CKD

Healthy habits can support long-term kidney health.

Consider:

• Maintaining a healthy weight

• Exercising regularly

• Avoiding smoking

• Limiting excessive salt

• Managing blood sugar

• Monitoring blood pressure

• Staying appropriately hydrated

• Following prescribed medications

Dietary recommendations should be individualized rather than applying the same restrictions to every person with CKD.

Does Stage 1 CKD Progress?

Stage 1 CKD does not necessarily progress to advanced kidney disease.

Progression risk depends on factors such as:

• Amount of albumin in urine

• Underlying kidney condition

• Blood pressure

• Diabetes control

• eGFR trend

• Smoking

• Cardiovascular disease

• Episodes of acute kidney injury

A person with stable kidney function and minimal albuminuria may have a substantially different risk profile from someone with significant proteinuria and progressive disease.

How Is Stage 1 CKD Diagnosed?

Doctors may use several investigations.

Blood Tests

• Serum creatinine

• eGFR

• Electrolytes when indicated

Urine Tests

• Urinalysis

• Urine albumin-to-creatinine ratio

• Other urine studies when required

Blood Pressure

Hypertension can contribute to kidney damage and needs regular monitoring.

Imaging

Ultrasound or other imaging may be recommended when structural kidney disease is suspected.

How Often Should Stage 1 CKD Be Monitored?

There is no single schedule that applies to everyone.

Monitoring depends on:

• Cause of CKD

• Albuminuria

• eGFR

• Blood pressure

• Diabetes

• Rate of kidney function change

Your nephrologist can determine an appropriate follow-up schedule.

Can You Live a Normal Life With Stage 1 CKD?

Many people with early kidney disease can continue their normal activities and maintain good quality of life.

The important point is not to ignore the diagnosis.

Regular monitoring and management of the underlying cause can help reduce the risk of progression.

Stage 1 CKD and Kidney Stones

Some patients with early CKD may also have recurrent kidney stones.

Repeated stones can cause urinary obstruction and other kidney complications.

Patients with recurrent stones may benefit from evaluation of:

• Stone composition

• Urine chemistry

• Dietary factors

• Metabolic risk factors

Stage 1 CKD and Diabetes

Diabetes can damage the kidney's filtering units over time.

People with diabetes should regularly monitor:

• Blood glucose

• Blood pressure

• Urine albumin

• eGFR

Early detection of albuminuria can help identify diabetic kidney disease before substantial loss of filtration occurs.

When Should You See a Nephrologist?

A nephrology consultation may be appropriate if you have:

• Persistent protein or albumin in urine

• Blood in the urine

• Abnormal kidney imaging

• Family history of kidney disease

• Diabetes with kidney abnormalities

• High blood pressure with evidence of kidney damage

• Recurrent kidney stones

• A persistent abnormal kidney function test

Early specialist assessment can clarify the cause and establish a long-term monitoring plan.

Frequently Asked Questions

Is stage 1 CKD serious?

Stage 1 represents early kidney disease. It should be taken seriously because the underlying cause needs to be identified and managed, but it does not mean that kidney failure is inevitable.

What is normal kidney function in stage 1 CKD?

An eGFR of 90 or higher can fall within the G1 category, but CKD requires evidence of kidney damage that persists over time.

Can stage 1 kidney disease go away?

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

Does stage 1 CKD require dialysis?

No. Dialysis is not a treatment for stage 1 CKD.

Can stage 1 CKD progress to stage 2?

It can, but progression is not inevitable. Risk depends on the underlying disease and factors such as albuminuria and the trend in kidney function.

Conclusion

Chronic kidney disease stage 1 is an early stage in which kidney filtration may remain preserved while evidence of kidney damage is present. Because symptoms are often absent, urine testing, eGFR monitoring and assessment of underlying causes are important.

Early kidney care can focus on controlling blood pressure and diabetes, managing albuminuria when appropriate, avoiding preventable kidney injury and monitoring kidney function over time.
