Chronic kidney disease (CKD) is a long-term condition in which the kidneys have abnormalities in their structure or function that persist over time.
The kidneys perform several essential functions. They remove waste products from the blood, regulate fluid and electrolyte balance, help control blood pressure and contribute to the production of hormones involved in red blood cell formation and bone health.
CKD can develop gradually and may remain unnoticed for years. This is why someone can have kidney damage even when they feel completely healthy.
The condition can range from early kidney abnormalities with preserved filtration to advanced kidney failure requiring kidney replacement therapy.
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 disorders.
What Causes Chronic Kidney Disease?
CKD can result from several medical conditions.
Diabetes
Diabetes is one of the major causes of chronic kidney disease. Persistently elevated blood glucose can damage the tiny blood vessels and filtering structures within the kidneys.
High Blood Pressure
Long-standing uncontrolled hypertension can damage kidney blood vessels and contribute to progressive loss of kidney function.
Glomerular Diseases
Conditions affecting the kidney's filtering units, such as certain forms of glomerulonephritis, can cause persistent protein or blood in the urine and progressive kidney damage.
Polycystic Kidney Disease
Some inherited conditions can cause multiple cysts to develop in the kidneys and gradually affect kidney function.
Recurrent Kidney Stones or Obstruction
Repeated obstruction, complicated stones or certain structural urinary conditions may contribute to kidney damage.
Previous Acute Kidney Injury
Some people who experience severe acute kidney injury may have an increased risk of developing or worsening chronic kidney disease.
Other Causes
Autoimmune disorders, inherited conditions, infections and certain medications or toxins can also affect kidney health.
What Are the Early Symptoms of Chronic Kidney Disease?
One of the most important facts about CKD is that early disease may cause no obvious symptoms.
When symptoms occur, they can include:
-
Persistent tiredness
-
Swelling around the ankles or feet
-
Puffiness around the eyes
-
Changes in urination
-
Foamy urine
-
Blood in urine
-
Increased or reduced urine output
-
High blood pressure
-
Muscle cramps
-
Poor appetite
-
Nausea
-
Itching
-
Sleep disturbances
These symptoms can have many other causes, so they cannot confirm CKD by themselves.
Blood and urine testing is often needed to identify kidney disease.
How Is Chronic Kidney Disease Diagnosed?
Doctors generally use a combination of kidney-function tests and evidence of kidney damage.
Serum Creatinine
Creatinine is a waste product filtered by the kidneys.
An elevated creatinine level can indicate reduced filtration, although the result must be interpreted in context.
eGFR
The estimated glomerular filtration rate provides an estimate of how well the kidneys are filtering blood.
The eGFR helps categorize CKD when abnormalities persist.
Urine Albumin
Albumin in the urine can be an important marker of kidney damage.
A urine albumin-to-creatinine ratio may be used to measure albumin loss.
Urinalysis
A urine examination may identify:
-
Blood
-
Protein
-
Infection
-
Crystals
-
Other abnormalities
Blood Pressure
Blood-pressure measurement is important because hypertension can both contribute to and result from kidney disease.
Imaging
Kidney ultrasound or other imaging may be recommended when doctors need to assess kidney size, stones, cysts, obstruction or structural abnormalities.
Understanding the Stages of Chronic Kidney Disease
CKD is commonly categorized according to eGFR, along with other evidence of kidney damage.
| CKD Stage | eGFR Range |
|---|---|
| Stage 1 | 90 or higher with evidence of kidney damage |
| Stage 2 | 60–89 with evidence of kidney damage |
| Stage 3a | 45–59 |
| Stage 3b | 30–44 |
| Stage 4 | 15–29 |
| Stage 5 | Below 15 |
An eGFR alone does not tell the complete story.
Urine albumin, the cause of kidney disease, duration of the abnormality and changes over time are also important.
What Happens as Chronic Kidney Disease Progresses?
CKD progression varies significantly.
Some people remain stable for many years, particularly when the underlying cause and risk factors are well controlled.
Others experience faster deterioration.
Factors that may contribute to progression include:
-
Poorly controlled blood pressure
-
Diabetes
-
Significant albuminuria
-
Smoking
-
Cardiovascular disease
-
Recurrent kidney injury
-
Certain kidney diseases
-
Medication-related kidney injury
-
Other individual risk factors
Regular monitoring allows treatment to be adjusted when necessary.
Treatment for Chronic Kidney Disease
There is no single medicine that cures every form of CKD.
Treatment is designed around the underlying cause and the patient's level of kidney function.
Control Blood Pressure
Maintaining blood pressure within the individualized target recommended by a healthcare professional is an important part of kidney protection.
Certain medicines may also help reduce albumin loss in selected patients.
Manage Diabetes
Good diabetes management can reduce the risk of kidney complications.
Depending on the patient's condition, certain glucose-lowering medicines may provide additional kidney or cardiovascular benefits.
Reduce Albuminuria
Persistent albumin in urine may indicate increased risk of kidney-function decline.
Appropriate medicines may reduce albumin loss and help protect kidney function in selected patients.
Manage Cholesterol and Cardiovascular Risk
People with CKD have an increased risk of cardiovascular disease.
Managing cholesterol, blood pressure, diabetes, smoking and other cardiovascular risk factors is therefore important.
Treat Complications
Advanced CKD can cause:
-
Anemia
-
Potassium abnormalities
-
Acid-base disturbances
-
Mineral and bone abnormalities
-
Fluid retention
These complications may require specific treatment and monitoring.
Can Chronic Kidney Disease Be Reversed?
In most cases, established chronic kidney damage cannot simply be reversed.
However, the progression of CKD can sometimes be slowed significantly by identifying the cause and managing important risk factors.
For example, appropriate treatment may help:
-
Control blood pressure
-
Reduce albuminuria
-
Improve diabetes management
-
Prevent recurrent kidney injury
-
Treat urinary obstruction
-
Avoid kidney-harming medications
-
Manage cardiovascular risk
An apparent decline in kidney function should also be evaluated because temporary factors such as dehydration, infection or medication effects can sometimes worsen kidney-test results.
Chronic Kidney Disease Diet
There is no universal diet that is suitable for every person with CKD.
Dietary recommendations depend on:
-
CKD stage
-
Potassium level
-
Phosphorus level
-
Protein intake
-
Blood pressure
-
Diabetes
-
Fluid status
-
Dialysis status
Depending on individual needs, a healthcare professional may recommend adjustments to:
-
Salt
-
Protein
-
Potassium
-
Phosphorus
-
Fluid intake
Avoid extreme diets or unnecessary protein restriction without professional guidance.
A renal dietitian can help create an individualized nutrition plan.
Drinking Water With Chronic Kidney Disease
Adequate hydration is important for many people, but more water is not necessarily better for everyone with CKD.
Patients with advanced kidney disease, reduced urine output, heart failure or fluid retention may need to limit their fluid intake.
Therefore, fluid recommendations should be based on kidney function and individual medical advice.
Medicines and Chronic Kidney Disease
As kidney function declines, some medicines may remain in the body for longer and require dose adjustment.
Patients with CKD should inform healthcare professionals about all medicines they take, including:
-
Prescription drugs
-
Over-the-counter medicines
-
Painkillers
-
Supplements
-
Herbal preparations
Certain nonsteroidal anti-inflammatory drugs (NSAIDs) can harm kidney function in susceptible people and should not be used routinely without appropriate medical advice.
Never stop an important prescribed medicine without consulting the prescribing doctor.
Can Lifestyle Changes Help Manage CKD?
Lifestyle measures can complement medical treatment.
Helpful habits may include:
-
Avoiding tobacco
-
Maintaining a healthy weight
-
Limiting excessive salt
-
Staying physically active according to your health status
-
Managing diabetes
-
Monitoring blood pressure
-
Avoiding unnecessary painkillers
-
Following individualized dietary recommendations
-
Attending regular kidney-function testing
Lifestyle changes cannot replace treatment for an established kidney disorder, but they can support overall kidney and cardiovascular health.
Who Should Be Tested for Chronic Kidney Disease?
Kidney-function testing may be particularly important for people with:
-
Diabetes
-
High blood pressure
-
Cardiovascular disease
-
Family history of kidney disease
-
Previous acute kidney injury
-
Recurrent kidney stones
-
Recurrent urinary infections
-
Known kidney abnormalities
-
Persistent protein or blood in urine
People with risk factors should discuss appropriate screening intervals with their healthcare professional.
When Should You See a Nephrologist?
A nephrologist specializes in medical kidney disease.
Specialist assessment may be appropriate when you have:
-
Persistently elevated creatinine
-
Reduced eGFR
-
Significant albumin or protein in urine
-
Unexplained blood in urine
-
Difficult-to-control blood pressure
-
Progressive decline in kidney function
-
Recurrent kidney stones
-
Electrolyte abnormalities
-
Advanced CKD
-
Kidney failure
Early specialist involvement can help identify the cause and establish a long-term management plan.
When Can Chronic Kidney Disease Become an Emergency?
CKD itself is often a long-term condition, but complications can become urgent.
Seek immediate medical attention for:
-
Very little or no urine
-
Severe breathlessness
-
Severe swelling
-
Confusion or altered consciousness
-
Persistent vomiting
-
Severe weakness
-
Chest pain
-
Severe dehydration
-
Rapid worsening of symptoms
These signs can indicate serious kidney or systemic complications.
What Happens in Advanced Chronic Kidney Disease?
When kidney function becomes severely reduced, doctors may discuss kidney replacement options.
These can include:
Hemodialysis
Blood is circulated through a dialysis machine to remove waste products and excess fluid.
Peritoneal Dialysis
The peritoneal membrane inside the abdomen is used to help remove waste products and fluid.
Kidney Transplantation
A kidney transplant may be an option for appropriately selected patients.
Conservative Kidney Management
Some patients may choose comprehensive conservative management rather than dialysis, depending on their health, prognosis and treatment preferences.
The appropriate approach is individualized.

Frequently Asked Questions
What is chronic kidney disease?
Chronic kidney disease is a long-term abnormality of kidney structure or function that persists over time. It can range from early kidney damage to advanced kidney failure.
What are the first signs of CKD?
Early CKD may have no noticeable symptoms. Protein or albumin in urine, elevated creatinine, reduced eGFR or high blood pressure may reveal kidney disease before symptoms appear.
Can chronic kidney disease be cured?
Established chronic kidney damage is generally not completely reversible. However, appropriate treatment can slow progression and help manage complications.
Can people with CKD drink plenty of water?
Fluid needs vary. Some people need adequate hydration, while those with advanced kidney disease, reduced urine output or fluid retention may require restrictions.
Does CKD always lead to dialysis?
No. Some people remain stable for many years without dialysis. Progression depends on the underlying cause, kidney function, albuminuria, other health conditions and response to treatment.
Which doctor treats chronic kidney disease?
A nephrologist specializes in the diagnosis and medical management of kidney diseases, including CKD and kidney failure.
Conclusion
Chronic kidney disease can develop silently and progress at different rates. Diabetes, high blood pressure, glomerular disorders, inherited conditions, recurrent urinary problems and other factors can contribute to long-term kidney damage.
Because early CKD may cause few or no symptoms, appropriate blood and urine testing is important, especially for people with recognized risk factors.
Treatment focuses on identifying the cause, protecting remaining kidney function, controlling blood pressure and diabetes, reducing albuminuria when appropriate and managing complications. In advanced disease, dialysis, transplantation or comprehensive conservative kidney management may be considered according to the individual's circumstances.
If you have an abnormal creatinine or eGFR, persistent protein in urine, difficult-to-control blood pressure or other kidney-related concerns, timely evaluation by a nephrologist can help determine the most appropriate next step.
