Chronic kidney disease (CKD) is a long-term condition in which the kidneys become damaged or lose their ability to filter waste and excess fluid effectively.

As CKD progresses, some patients eventually develop kidney failure and may need kidney replacement therapy, such as dialysis or kidney transplantation.

However, being diagnosed with CKD does not automatically mean that dialysis is required.

Dialysis is generally considered when kidney function has become severely reduced and the kidneys can no longer adequately maintain fluid, electrolyte and acid-base balance or control symptoms despite appropriate medical treatment.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and management for chronic kidney disease, advanced kidney failure and dialysis-related care.

What Is Chronic Kidney Disease?

CKD refers to abnormalities of kidney structure or function that persist over time.

Common causes include:

• Diabetes

• High blood pressure

• Glomerular kidney diseases

• Polycystic kidney disease

• Recurrent kidney injury

• Chronic urinary obstruction

• Certain inherited disorders

• Long-standing kidney inflammation

• Other medical conditions

CKD is commonly classified according to the estimated glomerular filtration rate (eGFR) and the amount of albumin or protein present in urine.

Early CKD may have few or no noticeable symptoms.

Does Everyone With CKD Need Dialysis?

No.

Many people with CKD never require dialysis.

With appropriate treatment, kidney-function decline can sometimes be slowed for many years.

Management may include:

• Blood-pressure control

• Diabetes management

• Reduction of excess urine albumin when appropriate

• Appropriate medicines

• Dietary management

• Avoiding unnecessary kidney-harming medicines

• Treatment of complications

• Regular kidney-function monitoring

Dialysis becomes relevant when kidney failure reaches a stage where kidney function is no longer sufficient to maintain health despite medical management.

At What Stage of CKD Is Dialysis Usually Considered?

Dialysis is most commonly associated with kidney failure or CKD stage 5, when eGFR is severely reduced.

However, eGFR alone does not determine the exact time dialysis should begin.

A person with a very low eGFR may remain clinically stable without immediate dialysis, while another person may need dialysis because of serious complications.

Doctors consider the entire clinical picture rather than using a single creatinine or eGFR number.

What Are the Signs That Dialysis May Be Needed?

Dialysis may be considered when advanced kidney disease causes complications that cannot be adequately controlled with medication and other measures.

Possible indications include:

Severe Fluid Overload

When the kidneys cannot remove enough fluid, swelling and breathlessness can develop.

Persistent High Potassium

Severely elevated potassium can affect the heart and may become life-threatening.

Severe Metabolic Acidosis

Kidney failure can impair the body's ability to maintain normal acid-base balance.

Uremic Symptoms

Accumulation of waste products may cause symptoms such as:

• Nausea

• Vomiting

• Loss of appetite

• Severe fatigue

• Confusion

• Itching

• Difficulty concentrating

Progressive Nutritional or Functional Decline

Advanced kidney failure may contribute to loss of appetite, weight loss and declining physical condition.

Inability to Control Fluid or Blood Chemistry

When medical treatment is no longer sufficient to control complications, kidney replacement therapy may be recommended.

Why Creatinine Alone Does Not Decide on Dialysis

Patients often ask about a particular creatinine level for dialysis.

There is no universal creatinine number that automatically means dialysis must begin.

Creatinine is influenced by factors such as:

• Age

• Muscle mass

• Diet

• Hydration

• Kidney function

• Certain medications

• Acute illness

Doctors therefore consider creatinine together with eGFR, potassium, bicarbonate, urine output, fluid status, symptoms and other findings.

What Is Hemodialysis?

Hemodialysis uses a dialysis machine and a specialized filter called a dialyzer to remove waste products and excess fluid from the blood.

During treatment:

1. Blood is circulated from the body to the dialysis machine.

2. The blood passes through a dialyzer.

3. Waste products and excess fluid are removed.

4. The treated blood returns to the body.

Hemodialysis may be performed at a dialysis center or, in selected circumstances, through a home dialysis program.

The treatment schedule is individualized.

What Is Peritoneal Dialysis?

Peritoneal dialysis uses the lining of the abdomen, called the peritoneum, as a natural filtering membrane.

Dialysis solution is introduced into the abdominal cavity through a catheter.

Waste products and excess fluid move into the dialysis solution, which is then drained and replaced.

Peritoneal dialysis can be performed using different schedules and techniques depending on the patient's medical needs and lifestyle.

Hemodialysis vs Peritoneal Dialysis

Both are forms of kidney replacement therapy, but they work differently.

Hemodialysis

• Uses a dialyzer outside the body

• Requires vascular access

• Can be performed in a dialysis center or at home in selected patients

• Treatment frequency depends on the prescribed dialysis plan

Peritoneal Dialysis

• Uses the peritoneal membrane

• Requires a peritoneal dialysis catheter

• Can often be performed at home

• Requires careful infection-prevention practices

The appropriate choice depends on medical suitability, lifestyle, home circumstances and patient preference.

How Is Dialysis Access Created?

Patients planning long-term hemodialysis may need vascular access.

Possible types include:

Arteriovenous Fistula

A connection is surgically created between an artery and vein.

Arteriovenous Graft

A synthetic or biological conduit may connect an artery and vein when a fistula is not suitable.

Central Venous Catheter

A catheter may be used when dialysis is needed urgently or while more permanent access is being prepared.

When long-term dialysis is anticipated, early access planning can help reduce complications.

What Happens Before Starting Long-Term Dialysis?

Preparation may begin before dialysis becomes urgent.

A nephrologist may discuss:

• Dialysis modality

• Vascular access

• Peritoneal dialysis catheter

• Dietary requirements

• Medication adjustments

• Vaccinations when appropriate

• Anemia management

• Bone and mineral health

• Cardiovascular risk

• Kidney transplantation

Early education gives patients and families time to understand their options.

Can Dialysis Be Delayed in CKD?

Sometimes.

Dialysis does not have to begin simply because eGFR has fallen below a particular value.

If symptoms and complications can be safely controlled through medical treatment, dialysis may not yet be necessary.

However, delaying dialysis when serious complications are present can be dangerous.

The decision should be individualized by a nephrologist.

Can Kidney Function Improve After Dialysis Starts?

It depends on why dialysis was started.

If dialysis was initiated because of acute kidney injury superimposed on CKD, kidney function may sometimes recover sufficiently for dialysis to be discontinued.

If dialysis is required because of irreversible end-stage kidney disease, long-term dialysis is usually necessary unless the patient receives a successful kidney transplant or another suitable treatment changes the situation.

This is why determining the cause of kidney failure is important.

What Are Common Symptoms in Advanced CKD?

People with advanced kidney disease may experience:

• Persistent tiredness

• Poor appetite

• Nausea

• Vomiting

• Itching

• Swelling of the legs or face

• Breathlessness

• Changes in urine output

• Sleep problems

• Muscle cramps

• Difficulty concentrating

Some people may have relatively few symptoms despite significant reduction in kidney function.

Regular monitoring is therefore important for people with advanced CKD.

What Tests Are Used Before and During Dialysis?

Doctors may monitor:

• Serum creatinine

• eGFR

• Urea

• Potassium

• Sodium

• Bicarbonate

• Calcium

• Phosphorus

• Hemoglobin

• Albumin

• Urine output

• Blood pressure

• Fluid status

The exact testing schedule depends on the patient's condition and dialysis treatment plan.

What Is Dialysis Adequacy?

Dialysis should remove enough waste and fluid to meet the patient's treatment needs.

Dialysis adequacy may be assessed using:

• Clinical symptoms

• Fluid status

• Laboratory results

• Dialysis dose measurements

• Treatment duration and frequency

• Overall nutritional and health status

A single creatinine result does not determine whether dialysis is adequate.

What Diet Is Recommended During Dialysis?

Dietary needs vary between patients.

A renal dietitian or nephrologist may provide guidance regarding:

Sodium

Excess sodium can contribute to thirst, fluid retention and high blood pressure.

Potassium

Some dialysis patients need to limit high-potassium foods depending on blood potassium levels.

Phosphorus

Advanced kidney disease can cause phosphorus accumulation, requiring dietary management and sometimes medicines called phosphate binders.

Protein

Protein requirements can differ between people with advanced CKD who are not on dialysis and people receiving dialysis.

Fluid

Fluid intake may need to be limited when urine production is reduced or fluid accumulates.

There is no single kidney diet that is appropriate for every dialysis patient.

What Are Possible Dialysis Complications?

Dialysis is an important life-supporting treatment, but complications can occur.

Possible problems include:

• Low blood pressure during dialysis

• Muscle cramps

• Fatigue

• Vascular-access infection

• Vascular-access blockage

• Catheter-related complications

• Fluid or electrolyte shifts

• Peritoneal dialysis-related infection

Regular medical follow-up helps identify and manage these problems.

Why Is Blood Pressure Control Important in CKD?

High blood pressure can both contribute to CKD and worsen kidney damage.

Managing blood pressure can help:

• Reduce cardiovascular risk

• Slow kidney-function decline in appropriate patients

• Reduce fluid-related complications

• Protect other organs

Blood-pressure targets should be individualized by the treating healthcare professional.

Diabetes and Chronic Kidney Disease

Diabetes is one of the leading causes of CKD.

People with diabetes and kidney disease may need:

• Blood glucose monitoring

• HbA1c assessment

• Urine albumin testing

• eGFR monitoring

• Blood-pressure management

• Kidney-protective diabetes treatment when appropriate

• Cardiovascular risk management

Diabetes treatment often needs to be adjusted as kidney function changes.

Kidney Transplantation as an Alternative to Long-Term Dialysis

For suitable patients with kidney failure, kidney transplantation can provide a functioning donor kidney and may eliminate the need for dialysis after successful transplantation.

Transplant evaluation can involve assessment of:

• General health

• Cardiovascular condition

• Infection risk

• Blood group and immunological factors

• Surgical suitability

• Medication requirements

• Ability to follow long-term transplant care

A nephrologist and transplant team can explain whether transplantation is appropriate.

Can CKD Be Managed Without Dialysis?

Many patients with CKD can be managed without dialysis, particularly before kidney failure develops.

Management may include:

• Treating the underlying disease

• Controlling blood pressure

• Managing diabetes

• Reducing proteinuria when appropriate

• Managing anemia

• Addressing mineral and bone abnormalities

• Dietary management

• Avoiding nephrotoxic exposures

• Regular monitoring

The objective is to preserve kidney function for as long as safely possible.

When Should a Person With CKD See a Nephrologist?

Specialist kidney evaluation may be appropriate when there is:

• Rapidly declining eGFR

• Persistently elevated creatinine

• Significant urine albumin or protein

• Difficult-to-control hypertension

• Recurrent acute kidney injury

• Electrolyte abnormalities

• Advanced CKD

• Symptoms suggestive of uremia

• Preparation for dialysis

• Questions about kidney transplantation

Early nephrology involvement can help patients understand treatment options before dialysis becomes urgent.

Frequently Asked Questions

At what stage of chronic kidney disease is dialysis needed?

Dialysis is most commonly required in kidney failure or CKD stage 5, but the decision is based on symptoms and complications rather than eGFR alone.

Can CKD patients avoid dialysis?

Some people with CKD never need dialysis, particularly when kidney disease is detected early and appropriately managed. However, advanced irreversible kidney failure may eventually require kidney replacement therapy.

Does a high creatinine level mean dialysis is necessary?

No. There is no single creatinine value that automatically requires dialysis. Doctors consider kidney function, symptoms, potassium, fluid status, acid-base balance and other complications.

Which is better for CKD: hemodialysis or peritoneal dialysis?

Neither is universally better. Both can be effective. The appropriate option depends on medical suitability, lifestyle, home circumstances and patient preference.

Can dialysis patients receive a kidney transplant?

Many patients with kidney failure can be evaluated for transplantation. Suitability depends on overall health and transplant-specific factors.

Can kidney function recover after dialysis starts?

Recovery may occur when dialysis was started for an acute and potentially reversible kidney injury. Recovery is much less likely when dialysis is required because of irreversible end-stage chronic kidney disease.

Conclusion

Chronic kidney disease dialysis is an important treatment option when advanced kidney failure prevents the kidneys from adequately maintaining fluid, electrolyte and waste balance.

However, dialysis should not be viewed as an automatic consequence of every CKD diagnosis. Many patients can remain stable for years with appropriate medical management, while others may require dialysis when kidney failure causes complications that cannot be controlled through conservative treatment.

When dialysis becomes necessary, patients may have options including hemodialysis, peritoneal dialysis and kidney transplantation, depending on their medical condition and individual circumstances.

Early nephrology care can help patients understand their kidney function, prepare for possible kidney replacement therapy and make informed decisions about treatment.
