The end stage of renal disease (ESRD) refers to advanced kidney failure in which the kidneys have lost most of their ability to perform essential functions such as removing waste products, balancing fluids and electrolytes, and maintaining acid-base balance.

This stage is also commonly called kidney failure or end stage kidney disease.

Kidney failure usually develops after significant progression of chronic kidney disease, although severe acute kidney injury or other serious conditions can sometimes lead to a need for kidney replacement therapy.

End stage renal disease requires close medical supervision. Depending on the person's condition, treatment may include hemodialysis, peritoneal dialysis, kidney transplantation or comprehensive conservative kidney management.

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

What Happens When the Kidneys Reach the End Stage?

Healthy kidneys perform several important functions. They:

• Remove metabolic waste from the blood

• Help control fluid balance

• Regulate electrolytes such as potassium and sodium

• Contribute to acid-base balance

• Produce hormones involved in red blood cell production

• Help regulate bone and mineral metabolism

• Contribute to blood-pressure regulation

When kidney function becomes severely impaired, these processes can become increasingly difficult for the body to maintain.

Waste products may accumulate, fluid may build up, potassium may become dangerously high and metabolic disturbances can develop.

The symptoms and complications vary considerably between individuals.

What Causes End Stage Renal Disease?

End stage kidney disease can develop from several long-term kidney conditions.

Common causes include:

Diabetes

Diabetes can damage the small blood vessels and filtering structures within the kidneys over time.

Persistent high blood glucose can contribute to albuminuria and progressive loss of kidney function.

High Blood Pressure

Long-standing uncontrolled hypertension can damage kidney blood vessels and contribute to progressive kidney disease.

Kidney disease can also make blood pressure more difficult to control, creating a cycle that requires careful management.

Glomerular Diseases

Conditions affecting the kidney's filtering units can cause persistent protein loss, blood in urine and progressive kidney damage.

Examples include certain forms of glomerulonephritis and FSGS.

Polycystic Kidney Disease

Inherited disorders such as autosomal dominant polycystic kidney disease can gradually damage kidney tissue and eventually result in kidney failure in some affected individuals.

Recurrent Kidney Injury

Repeated episodes of acute kidney injury may contribute to permanent kidney damage in some patients.

Urinary Obstruction

Long-standing obstruction caused by stones, strictures, prostate enlargement or other conditions can impair kidney function.

Other Kidney Diseases

Autoimmune diseases, inherited disorders, chronic infections and other kidney conditions may also contribute to advanced renal failure.

Identifying the original cause remains important even after kidney function becomes severely reduced because it can influence treatment and management.

What Are the Symptoms of End Stage Renal Disease?

Symptoms can become more noticeable as kidney function declines, although some people may have relatively few symptoms despite severe laboratory abnormalities.

Possible symptoms include:

• Persistent tiredness

• Weakness

• Reduced appetite

• Nausea

• Vomiting

• Itching

• Swelling of the feet, ankles or face

• Breathlessness

• Muscle cramps

• Sleep disturbances

• Difficulty concentrating

• Changes in urine output

• Unpleasant taste in the mouth

• Weight changes related to fluid or nutritional problems

These symptoms are not specific to kidney failure and may occur in other medical conditions.

Does End Stage Renal Disease Always Cause Swelling?

No.

Fluid retention can cause swelling in people with advanced kidney failure, but not every patient develops noticeable edema.

Swelling may appear around the:

• Ankles

• Feet

• Legs

• Hands

• Face

Fluid can also accumulate in the lungs and contribute to breathlessness.

Sudden or severe breathlessness requires urgent medical assessment.

What Tests Are Used to Evaluate End Stage Renal Disease?

A nephrologist may use several investigations to evaluate the severity and complications of advanced kidney disease.

Kidney Function Tests

Blood testing commonly includes:

• Serum creatinine

• eGFR

• Blood urea

• Electrolytes

• Bicarbonate

Creatinine should not be interpreted in isolation. Trends in kidney function and the patient's overall clinical condition are important.

Urine Testing

Depending on the situation, doctors may assess:

• Urine protein

• Urine albumin

• Blood

• Infection

• Urine volume

Blood Counts

Advanced kidney disease may contribute to anemia, so hemoglobin and other blood-count measurements may be monitored.

Mineral and Bone Tests

Calcium, phosphorus, parathyroid hormone and related measurements may be evaluated when appropriate.

Imaging

Ultrasound or other imaging may be used to evaluate kidney size, structural abnormalities, obstruction or other relevant findings.

What Is the eGFR in End Stage Renal Disease?

An eGFR below 15 mL/min/1.73 m² falls within the kidney-failure range.

However, an eGFR number alone does not determine exactly when dialysis should begin.

Doctors also consider:

• Symptoms

• Fluid overload

• Potassium levels

• Acid-base abnormalities

• Nutritional status

• Uremic complications

• Urine output

• Overall health

• Response to medical treatment

• Patient preferences and treatment goals

Some patients may be managed without immediate dialysis while preparation for kidney replacement therapy is undertaken.

What Is Uremia?

Uremia refers to a clinical syndrome associated with severe kidney dysfunction and accumulation of waste products and other metabolic abnormalities.

Possible manifestations can include:

• Nausea and vomiting

• Loss of appetite

• Severe fatigue

• Itching

• Difficulty concentrating

• Confusion

• Sleep disturbances

• Muscle twitching

• Pericarditis or other serious complications in severe cases

Suspected uremic complications require prompt assessment by a medical team.

When Is Dialysis Considered in End Stage Renal Disease?

Dialysis may be required when kidney function is insufficient to maintain safe internal balance and complications cannot be adequately controlled with medical treatment.

Potential indications can include:

• Persistent severe fluid overload

• Pulmonary edema

• Dangerous potassium elevation that does not respond adequately to medical treatment

• Severe metabolic acidosis

• Significant uremic symptoms or complications

• Certain toxin exposures

• Progressive kidney failure with inadequate clearance and significant complications

There is no single creatinine value that automatically means dialysis is required.

The nephrologist makes this decision after considering the complete clinical picture.

Hemodialysis for End Stage Renal Disease

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

Blood travels through a specialized access and is filtered before returning to the body.

Common types of vascular access include:

• Arteriovenous fistula

• Arteriovenous graft

• Dialysis catheter

For patients expected to need long-term hemodialysis, early discussion about vascular access can be important.

Dialysis frequency and treatment duration are individualized according to clinical needs.

Peritoneal Dialysis

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

Dialysis fluid 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 may be performed at home for appropriately selected patients after training and preparation.

The choice between hemodialysis and peritoneal dialysis depends on medical factors, lifestyle, home circumstances, patient preference and the recommendations of the treating team.

Is Kidney Transplantation an Option?

For appropriately selected patients with kidney failure, kidney transplantation can be an important kidney replacement treatment.

A transplant involves placing a functioning donor kidney into the recipient.

Potential transplant evaluation may consider:

• Overall health

• Heart and blood-vessel health

• Infections

• Cancer screening

• Previous medical conditions

• Immunological compatibility

• Ability to follow long-term treatment

• Availability of an appropriate donor

After transplantation, patients require lifelong medical follow-up and immunosuppressive treatment.

A transplant is not suitable for every patient, so assessment by a transplant team is essential.

Can End Stage Renal Disease Be Reversed?

Established chronic kidney failure is generally not simply reversed with a medicine or home remedy.

However, the situation can differ when severe kidney dysfunction is caused by an acute and potentially reversible condition.

A person with advanced kidney disease may also experience temporary worsening due to:

• Dehydration

• Infection

• Medication effects

• Urinary obstruction

• Acute illness

Treating such problems can sometimes improve kidney function.

Therefore, a sudden deterioration in a patient with advanced kidney disease should always be evaluated rather than automatically assumed to be permanent.

What Is Conservative Kidney Management?

Not every patient with kidney failure chooses or is suitable for dialysis or transplantation.

Conservative kidney management focuses on controlling symptoms, managing complications and supporting quality of life without dialysis.

Depending on the individual situation, care may address:

• Fluid-related symptoms

• Blood pressure

• Anemia

• Nausea

• Itching

• Pain

• Appetite and nutrition

• Electrolyte abnormalities

• Psychological and social support

Treatment decisions should involve the patient, family and healthcare team, taking medical circumstances and personal goals into account.

Nutrition in End Stage Renal Disease

Dietary needs change as kidney function declines and may also change after dialysis begins.

Depending on laboratory results and treatment modality, dietary advice may address:

• Sodium

• Potassium

• Phosphorus

• Protein

• Fluid intake

• Calorie intake

There is no single renal diet suitable for every patient.

For example, people receiving dialysis may have different protein requirements from people with advanced CKD who are not yet on dialysis.

A renal dietitian or nephrologist can provide individualized guidance.

Fluid Management in Kidney Failure

Fluid intake must be personalized.

Some patients with advanced kidney disease retain fluid and may require a fluid limit.

Others may have significant fluid losses or specific medical circumstances requiring different advice.

Drinking excessive water does not restore severely damaged kidneys and can worsen fluid overload in susceptible patients.

Follow the fluid recommendation provided by your healthcare team.

Managing Blood Pressure in Advanced Kidney Disease

Blood-pressure management remains important even when kidney function is severely reduced.

Treatment may involve:

• Appropriate medicines

• Sodium reduction

• Fluid management

• Regular blood-pressure monitoring

• Management of other cardiovascular risk factors

Medication choices need to account for kidney function, potassium levels and the patient's overall condition.

Anemia in End Stage Renal Disease

The kidneys contribute to production of erythropoietin, a hormone involved in red blood cell production.

Severe kidney disease can therefore contribute to anemia.

Patients may experience:

• Fatigue

• Weakness

• Reduced exercise tolerance

• Breathlessness

Evaluation may include hemoglobin, iron status and other relevant tests.

Treatment depends on the cause and may include iron therapy, erythropoiesis-stimulating agents or other interventions when appropriate.

Potassium Problems in Advanced Renal Failure

The kidneys help remove excess potassium.

In severe kidney dysfunction, potassium can accumulate in the blood.

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

Patients with advanced kidney disease should not make major dietary potassium changes without medical advice because requirements vary according to kidney function, medications and laboratory results.

How Can Kidney Failure Progression Be Managed?

For patients who still have meaningful residual kidney function, management may focus on preserving it for as long as possible.

Depending on the cause and clinical situation, this can include:

• Blood-pressure management

• Diabetes control

• Appropriate reduction of albuminuria

• Avoiding unnecessary kidney-harming medicines

• Treating infections

• Managing anemia and mineral abnormalities

• Dietary management

• Monitoring electrolytes

• Regular nephrology follow-up

Even advanced kidney disease benefits from appropriate management because complications can change over time.

Preparing for Kidney Replacement Therapy

When progression toward kidney failure is anticipated, early planning can help avoid urgent dialysis initiation when possible.

Planning may involve:

• Discussing hemodialysis

• Discussing peritoneal dialysis

• Planning vascular access

• Evaluating transplant eligibility

• Reviewing medications

• Nutrition counselling

• Understanding home-based treatment options

• Discussing conservative management when appropriate

Early education allows patients and families to understand their choices before an emergency develops.

When Is End Stage Renal Disease an Emergency?

Advanced kidney disease requires urgent medical attention when serious complications develop.

Seek immediate medical care for symptoms such as:

• Severe breathlessness

• Chest pain

• Confusion

• Fainting

• Very little or no urine

• Severe or rapidly increasing swelling

• Persistent vomiting

• Severe weakness

• Symptoms associated with dangerously high potassium

• Rapid deterioration in general health

These symptoms can indicate complications requiring urgent treatment.

How Can Patients With Kidney Failure Protect Their Health?

Patients with advanced renal disease can support their health by:

• Taking prescribed medicines consistently

• Attending scheduled nephrology appointments

• Following individualized fluid recommendations

• Monitoring blood pressure

• Following the recommended renal diet

• Keeping diabetes under appropriate control

• Avoiding unapproved supplements and herbal remedies

• Avoiding unnecessary painkillers

• Reporting significant changes in urine output

• Keeping dialysis sessions and transplant-related appointments as scheduled

Family members can also help patients maintain medication schedules and attend medical appointments.

Frequently Asked Questions

What is the end stage of renal disease?

End stage renal disease is advanced kidney failure in which the kidneys can no longer adequately perform their essential functions. Kidney replacement therapy or comprehensive conservative management may be required depending on the individual situation.

What are the signs of end stage renal disease?

Possible signs include severe fatigue, swelling, nausea, vomiting, itching, appetite loss, changes in urine output, breathlessness and difficulty concentrating. Some patients may have few symptoms despite severe kidney dysfunction.

What eGFR is considered end stage renal disease?

An eGFR below 15 mL/min/1.73 m² is within the kidney-failure range. However, eGFR alone does not determine whether dialysis must start.

Does everyone with end stage renal disease need dialysis?

Not necessarily. Dialysis decisions depend on symptoms, complications, laboratory findings, fluid status, residual kidney function and the overall clinical situation.

Can end stage renal disease be cured?

Established chronic kidney failure generally cannot be cured with medication. Dialysis, kidney transplantation and conservative kidney management are treatment approaches used according to individual circumstances.

Can kidney function improve in advanced renal disease?

A sudden decline caused by a reversible problem may improve when the underlying cause is treated. Permanent chronic kidney damage, however, generally cannot simply be reversed.

Is kidney transplant better than dialysis?

Dialysis and transplantation are different kidney replacement options, and suitability varies from patient to patient. Transplant evaluation depends on medical eligibility, while dialysis may be necessary for patients who are not transplant candidates or while awaiting transplantation.

Conclusion

The end stage of renal disease represents advanced loss of kidney function and requires careful, ongoing medical management. Symptoms may include swelling, fatigue, nausea, itching, appetite loss, breathlessness and changes in urine output, but symptoms alone cannot determine the severity of kidney failure.

Evaluation typically includes kidney-function tests, electrolyte monitoring, urine assessment and evaluation for complications.

When kidney function is no longer sufficient to maintain the body's balance, treatment may involve hemodialysis, peritoneal dialysis or kidney transplantation. Some patients may instead receive comprehensive conservative kidney management based on their medical condition and treatment goals.

Early discussion with a nephrologist can help patients and families understand treatment choices and prepare for kidney replacement therapy when necessary.
