CKD Kidney Disease: Symptoms, Causes, Stages, Treatment and Long-Term Kidney Care

Learn about CKD kidney disease, including early symptoms, common causes, eGFR stages, diagnosis, treatment, diet, prevention and when to consult a nephrologist.

11 Nov, 2026

CKD kidney disease, commonly called chronic kidney disease (CKD), is a long-term condition in which there is persistent kidney damage or reduced kidney function.

The kidneys perform several important functions. They remove waste products from the blood, regulate fluid and electrolyte balance, help control blood pressure and contribute to the production of red blood cells and maintenance of bone health.

CKD can develop gradually and may remain unnoticed during its early stages. Some people discover the condition through routine blood or urine testing before they experience noticeable symptoms.

CKD is not one single disease. Diabetes, high blood pressure, glomerular disorders, inherited conditions, recurrent obstruction and other kidney problems can contribute to chronic kidney damage.

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 and other kidney-function problems.


Why Does CKD Develop?

CKD can have many underlying causes.

Common contributors include:

  • Diabetes

  • Long-standing high blood pressure

  • Glomerular kidney diseases

  • Polycystic kidney disease

  • Recurrent urinary obstruction

  • Repeated kidney infections in some patients

  • Certain inherited kidney disorders

  • Autoimmune diseases

  • Repeated episodes of acute kidney injury

  • Other structural or medical kidney conditions

The cause of CKD matters because treatment may differ substantially between patients.

For example, a person with significant urine protein from glomerular disease may need a different treatment strategy from someone whose kidney function has been affected primarily by long-standing hypertension.


What Happens to the Kidneys in CKD?

Healthy kidneys continuously filter blood and remove waste products through urine.

When chronic kidney damage develops, functioning kidney tissue may gradually become less able to perform these tasks.

As kidney function decreases, patients may develop:

  • Waste-product accumulation

  • Fluid retention

  • Electrolyte abnormalities

  • Acid-base disturbances

  • Anemia

  • Mineral and bone abnormalities

  • Increased cardiovascular risk

The rate of progression is different for every patient.

Some people remain stable for many years, while others experience progressive loss of kidney function.


What Are the Early Symptoms of CKD?

Early CKD often causes few or no obvious symptoms.

When symptoms do occur, they may be nonspecific.

Possible signs include:

  • Tiredness

  • Swelling around the ankles or feet

  • Foamy urine

  • Blood in urine

  • Changes in urine frequency

  • High blood pressure

  • Reduced appetite

  • Nausea

  • Muscle cramps

  • Itching

  • Sleep disturbances

These symptoms do not prove that a person has CKD.

Kidney testing is particularly important for people who have risk factors such as diabetes or hypertension.


CKD Kidney Disease and eGFR

The estimated glomerular filtration rate (eGFR) is commonly used to assess kidney filtration.

For adults with established CKD, the G stages are generally categorized as follows:

CKD Stage eGFR
G1 90 or higher
G2 60–89
G3a 45–59
G3b 30–44
G4 15–29
G5 Less than 15

An important point is that eGFR of 60–89 does not by itself establish CKD. For G1 and G2, there needs to be evidence of kidney damage, such as persistent albuminuria or another marker of kidney abnormality, generally present for at least three months.

G5 indicates severely reduced kidney function, but dialysis is not started solely because an eGFR has crossed one numerical threshold. Symptoms, complications and the overall clinical situation are considered.


What Tests Help Diagnose CKD?

Doctors generally use several pieces of information rather than relying on one blood-test result.

Serum Creatinine

Creatinine is a waste product that is commonly measured to estimate kidney filtration.

A high creatinine level can indicate reduced kidney filtration, but it can also be influenced by muscle mass, hydration, diet, medications and acute illness.

eGFR

eGFR provides an estimate of filtration and helps classify the severity of chronic kidney disease.

Urine Albumin Testing

A urine albumin-to-creatinine ratio (UACR) can identify albumin leakage from the kidneys.

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

Urinalysis

A urine test can identify:

  • Blood

  • Protein

  • Infection

  • Other abnormalities

Blood Tests

Depending on the stage and suspected cause, testing may include:

  • Potassium

  • Sodium

  • Bicarbonate

  • Hemoglobin

  • Calcium

  • Phosphorus

  • Glucose

Imaging

Ultrasound or other imaging may be recommended to evaluate kidney size, urinary obstruction, cysts, stones or structural abnormalities.


CKD Kidney Disease Caused by Diabetes

Diabetes is an important risk factor for chronic kidney disease.

Persistently high blood glucose can damage the kidney's filtering structures over time.

One of the earliest measurable abnormalities may be increased albumin in the urine.

Kidney monitoring in people with diabetes commonly includes:

  • eGFR

  • UACR

  • Serum creatinine

  • Blood-pressure assessment

  • Diabetes control assessment

Diabetes does not mean that kidney failure is inevitable. Appropriate management of glucose, blood pressure, albuminuria and cardiovascular risk can help protect kidney health.

Importantly, a person with diabetes can also develop kidney problems from causes other than diabetic kidney disease, such as dehydration, acute kidney injury, stones, obstruction, infection or other kidney disorders.


CKD and High Blood Pressure

High blood pressure and CKD can influence each other.

Long-term hypertension can damage blood vessels and kidney tissue. Kidney disease can also contribute to elevated blood pressure through changes in fluid and hormone regulation.

Blood-pressure treatment is therefore an important part of CKD management.

Depending on the individual situation, doctors may prescribe medicines that help control blood pressure and reduce albuminuria.

Kidney function and potassium may need monitoring when certain kidney-protective medicines are used.


Understanding Albuminuria in CKD

Albuminuria means that albumin is being lost into the urine.

Persistent albuminuria may indicate damage to the kidney's filtering barrier.

It is useful not only for identifying kidney damage but also for assessing the risk of CKD progression.

Treatment that reduces albuminuria may be appropriate in selected patients.

However, the cause of protein or albumin in urine should be investigated rather than assuming every case represents the same disease.


Can CKD Kidney Disease Be Reversed?

This depends on what caused the kidney problem.

Some temporary changes in kidney function can improve when an acute contributing factor is corrected.

However, established chronic structural kidney damage or scarring is generally not simply reversed with a medicine or home remedy.

The goals of CKD care may therefore include:

  • Identifying the underlying cause

  • Preserving remaining kidney function

  • Reducing factors that accelerate progression

  • Treating complications

  • Lowering cardiovascular risk

  • Preparing for kidney replacement therapy when necessary

Early management can be particularly important because CKD may progress silently.


Treatment for CKD Kidney Disease

There is no single medicine that treats every form of CKD.

Treatment is tailored to the cause, kidney-function level, urine findings and other health conditions.

Management may include:

Blood-Pressure Treatment

Maintaining blood pressure within an individualized target can help reduce cardiovascular and kidney risks.

Diabetes Management

Appropriate glucose control can help reduce the risk of kidney complications in people with diabetes.

Medicines That Reduce Albuminuria

ACE inhibitors or ARBs may be prescribed for selected patients, particularly when albuminuria is present.

SGLT2 Inhibitors

SGLT2 inhibitors may provide kidney and cardiovascular benefits for appropriate patients with CKD, including many people with diabetes and some without diabetes.

Eligibility depends on kidney function and other clinical factors.

Management of Complications

Doctors may treat:

  • Anemia

  • High potassium

  • Acidosis

  • Mineral and bone abnormalities

  • Fluid overload

according to the patient's laboratory results and symptoms.

Medication Review

Some medicines require dose adjustments when kidney function declines.

Unnecessary kidney-harming medicines should be avoided where possible.


CKD Kidney Disease Diet

There is no single CKD diet suitable for every patient.

Dietary recommendations depend on:

  • CKD stage

  • Potassium level

  • Phosphorus level

  • Proteinuria

  • Diabetes

  • Blood pressure

  • Nutritional status

  • Fluid balance

  • Dialysis status

Depending on the individual situation, a healthcare professional may recommend controlling excessive sodium intake and adjusting protein, potassium, phosphorus or fluids.

Patients should avoid extreme dietary restrictions without professional guidance because inadequate nutrition can also be harmful.


Fluid Intake in CKD

Fluid requirements vary considerably.

Some people with CKD can drink according to normal thirst and medical guidance, while others with advanced disease or fluid overload may require a specific fluid limit.

Therefore, drinking excessive amounts of water is not a universal treatment for CKD.

People with kidney disease should follow individualized fluid advice, particularly when swelling, reduced urine output or heart disease is present.


CKD and Anemia

As kidney function declines, the kidneys may produce less erythropoietin, a hormone involved in red blood cell production.

CKD-related anemia can contribute to:

  • Fatigue

  • Weakness

  • Reduced exercise tolerance

  • Breathlessness

Doctors may investigate other causes of anemia, such as iron deficiency, before selecting treatment.

Depending on the cause and severity, management may involve iron therapy or other treatments.


CKD and Bone or Mineral Problems

Advanced CKD can disturb the balance of calcium, phosphorus, vitamin D and parathyroid hormone.

These changes can affect bone health and contribute to mineral-bone disorder associated with CKD.

Monitoring may include:

  • Calcium

  • Phosphorus

  • Parathyroid hormone

  • Vitamin D in selected circumstances

  • Alkaline phosphatase

Treatment depends on the laboratory findings and stage of kidney disease.


CKD and Heart Health

People with CKD have an increased risk of cardiovascular disease.

High blood pressure, diabetes, albuminuria, anemia, abnormal cholesterol levels and other factors may contribute to this risk.

Kidney care therefore includes more than monitoring creatinine.

Doctors may also address:

  • Blood pressure

  • Diabetes

  • Cholesterol

  • Smoking

  • Weight

  • Physical activity

  • Cardiovascular risk factors


Can Lifestyle Changes Help With CKD?

Lifestyle measures can complement medical treatment.

Depending on individual health needs, these may include:

  • Avoiding excessive salt

  • Maintaining a healthy body weight

  • Staying physically active as appropriate

  • Keeping diabetes under control

  • Monitoring blood pressure

  • Avoiding tobacco

  • Avoiding unnecessary painkillers

  • Taking prescribed medicines correctly

  • Avoiding unverified herbal kidney remedies

  • Attending scheduled kidney tests

Lifestyle changes should complement, rather than replace, medical treatment.


What Happens When CKD Becomes Advanced?

As kidney function becomes severely reduced, complications may become more difficult to control.

Advanced CKD can involve:

  • Severe fluid retention

  • Persistent electrolyte abnormalities

  • Acidosis

  • Anemia

  • Mineral-bone abnormalities

  • Loss of appetite

  • Nausea

  • Itching

  • Reduced physical capacity

  • Symptoms related to uremia

At this stage, nephrology care becomes particularly important.

Treatment planning may include dialysis education, vascular access planning, peritoneal dialysis assessment, transplant evaluation or conservative kidney management depending on the patient's circumstances and preferences.


Does CKD Always Lead to Dialysis?

No.

Many people with CKD do not require dialysis.

Progression varies according to the cause of CKD, degree of albuminuria, blood-pressure control, diabetes, age, other health conditions and other factors.

Dialysis is generally considered when kidney failure results in complications that cannot be adequately controlled with medical treatment.

The decision is based on the patient's clinical condition rather than a single creatinine or eGFR number.


How Can CKD Progression Be Slowed?

The approach depends on the cause, but kidney-protection strategies may include:

  • Controlling blood pressure

  • Managing diabetes

  • Treating albuminuria appropriately

  • Using kidney-protective medicines when indicated

  • Avoiding unnecessary nephrotoxic exposures

  • Maintaining an appropriate diet

  • Monitoring kidney function

  • Managing cardiovascular risk

  • Treating recurrent urinary obstruction or other underlying causes

  • Following regular nephrology care when required

Changes in eGFR and urine albumin over time can be more informative than a single measurement.


When Should You See a Nephrologist?

A kidney specialist may be appropriate if you have:

  • Persistent high creatinine

  • Reduced eGFR

  • Persistent protein or albumin in urine

  • Blood in urine without an established explanation

  • Difficult-to-control hypertension

  • Recurrent acute kidney injury

  • Progressive decline in kidney function

  • Significant electrolyte abnormalities

  • Advanced CKD

  • Kidney failure

People with diabetes or hypertension may also benefit from regular kidney screening based on their risk profile.


Warning Signs That Need Urgent Medical Attention

Seek urgent medical care if kidney disease is accompanied by:

  • Very little or no urine

  • Severe breathlessness

  • Rapidly increasing swelling

  • Chest pain

  • Confusion

  • Persistent vomiting

  • Severe weakness

  • Fainting

  • Rapid deterioration in health

These symptoms can indicate serious kidney or systemic complications.

Frequently Asked Questions

What does CKD kidney disease mean?

CKD kidney disease refers to chronic kidney disease, a condition involving persistent kidney damage or reduced kidney function over time.

Can CKD be cured?

There is no universal cure for established CKD. Some reversible factors may improve kidney function, while chronic structural damage generally requires long-term management to preserve remaining kidney function.

What are the first signs of CKD?

Early CKD may have no noticeable symptoms. Protein or albumin in urine, abnormal kidney-function tests and high blood pressure may identify the condition before symptoms become obvious.

Is CKD the same as kidney failure?

No. CKD includes a broad range of kidney-function levels. Kidney failure represents very advanced loss of kidney function and may require kidney replacement therapy.

Can a person with CKD live without dialysis?

Yes. Many people with CKD do not need dialysis. Even advanced kidney disease requires individualized assessment before deciding whether kidney replacement therapy is necessary.

What is the role of eGFR in CKD?

eGFR estimates kidney filtration and is used to classify CKD severity. It is interpreted alongside urine albumin, the cause of kidney disease, symptoms and changes over time.

Can diet improve CKD?

An individualized diet can support kidney health and help manage complications, but there is no universal diet that reverses CKD. Sodium, protein, potassium, phosphorus and fluid intake may need adjustment depending on the patient.

Should I drink more water if I have CKD?

Not necessarily. Fluid needs depend on kidney function, urine output, swelling, heart health and other factors. Excessive fluid can be harmful in some patients.


Conclusion

CKD kidney disease is a long-term condition that can affect kidney filtration and the body's fluid, electrolyte and metabolic balance. Because early CKD may produce few symptoms, blood and urine testing can be important for people at increased risk.

Diabetes, high blood pressure, glomerular disorders, inherited diseases and other kidney conditions can contribute to CKD. Treatment focuses on identifying the underlying cause, protecting remaining kidney function, managing complications and reducing cardiovascular and kidney-related risks.

CKD does not automatically mean dialysis. Many patients can remain stable for long periods with appropriate treatment and monitoring, while advanced disease may eventually require planning for dialysis, transplantation or other forms of kidney replacement therapy.

If you have an abnormal creatinine result, reduced eGFR, persistent protein in urine or another kidney-related concern, specialist evaluation can help determine the cause and appropriate management.
