ESRD stands for end-stage renal disease. It is a term used for kidney failure in which kidney function has become severely reduced and kidney replacement therapy such as dialysis or kidney transplantation may be required.

Kidney failure is generally associated with kidney function below about 15% of normal, often corresponding to an eGFR below 15 mL/min/1.73 m². However, an eGFR value alone does not determine exactly when dialysis should begin. Symptoms, fluid status, electrolyte abnormalities, acid-base problems and the overall clinical condition are also important.

The term ESKD (end-stage kidney disease) is also commonly used. NIDDK describes ESRD as kidney failure treated with dialysis or kidney transplantation.

ESRD, Stage 5 CKD and Kidney Failure: Are They the Same?

These terms are closely related but should not always be used interchangeably without context.

Stage G5 CKD refers to very severely reduced kidney function, generally an eGFR below 15 that persists for the required period or a patient already receiving dialysis.

Kidney failure means the kidneys can no longer perform enough of their essential functions to maintain the body's internal balance without additional treatment.

ESRD or ESKD generally refers to kidney failure requiring or being treated with dialysis or transplantation.

This distinction matters because someone can have a very low eGFR and require careful preparation for kidney replacement therapy without necessarily starting dialysis immediately.

What Happens to the Body in ESRD?

Healthy kidneys perform several important functions. They:

• Remove waste products from the blood

• Remove excess water

• Help regulate sodium and potassium

• Contribute to acid-base balance

• Help regulate blood pressure

• Produce hormones involved in red blood cell production

• Support healthy bones and mineral balance

When kidney function becomes severely impaired, these functions may become difficult to maintain.

As waste products and excess fluid accumulate, symptoms and complications can develop.

Common Symptoms of ESRD

Symptoms can develop gradually, and some people may have significant kidney dysfunction before they feel seriously unwell.

Possible symptoms include:

• Persistent tiredness

• Reduced appetite

• Nausea

• Vomiting

• Itching

• Swelling of the feet, ankles or legs

• Reduced urine production

• Muscle cramps

• Weakness

• Sleep difficulties

• Difficulty concentrating

• Confusion

• Breathlessness

• Changes in taste

• Unexplained weight changes

These symptoms are not specific to ESRD and can have other causes. Kidney function therefore needs to be assessed with appropriate blood and urine testing.

Why Do Patients With ESRD Develop Swelling?

Severely reduced kidney function can make it difficult for the body to remove enough sodium and water.

The retained fluid may collect in tissues, causing edema.

Swelling can appear around:

• Feet

• Ankles

• Lower legs

• Hands

• Face

If excess fluid accumulates significantly, it may also contribute to breathlessness.

Fluid management is therefore an important component of advanced kidney care.

Does ESRD Always Mean Immediate Dialysis?

No.

A very low eGFR is an important indicator of advanced kidney failure, but dialysis is not started solely because a particular creatinine or eGFR number has been reached.

The nephrologist considers whether kidney failure is causing complications that cannot be controlled safely with medical treatment.

Potential reasons for starting dialysis can include:

• Difficult-to-control fluid overload

• Dangerous potassium abnormalities

• Significant metabolic acidosis

• Uremic symptoms or complications

• Severe symptoms related to kidney failure

• Progressive inability of the kidneys to maintain the body's internal balance

The decision should be individualized between the patient and kidney-care team.

How Is ESRD Diagnosed?

Diagnosis involves more than one laboratory value.

Kidney Function Testing

Blood tests commonly include:

• Serum creatinine

• eGFR

• Urea

• Sodium

• Potassium

• Bicarbonate

These results help assess the degree of kidney dysfunction and associated metabolic problems.

Urine Testing

Depending on the condition, doctors may assess:

• Urine protein

• Albumin

• Blood

• Infection

• Other abnormalities

Blood Pressure Assessment

Advanced kidney disease can be associated with difficult-to-control blood pressure, and hypertension can also contribute to kidney damage.

Additional Evaluation

Depending on the patient's history, doctors may evaluate:

• Hemoglobin

• Calcium

• Phosphorus

• Parathyroid hormone

• Nutritional status

• Cardiovascular health

• Kidney imaging

The exact investigations depend on the patient's underlying disease and current condition.

What Causes ESRD?

ESRD is not a single disease. It can result from several long-term kidney conditions.

Diabetes-Related Kidney Disease

Diabetes can progressively damage the kidney's filtering structures and is a major cause of kidney failure.

Long-Standing High Blood Pressure

Poorly controlled hypertension can damage kidney blood vessels and accelerate chronic kidney disease.

Glomerular Diseases

Conditions affecting the kidney's filtering units can cause persistent proteinuria, blood in urine and progressive loss of kidney function.

Polycystic Kidney Disease

Inherited kidney disorders such as polycystic kidney disease can gradually reduce kidney function.

Recurrent Kidney Injury

Repeated episodes of acute kidney injury or severe kidney damage may contribute to permanent loss of kidney function.

Obstructive Kidney Disease

Long-standing urinary obstruction caused by stones, strictures, prostate-related obstruction or other conditions can sometimes cause chronic kidney damage.

Other Kidney Diseases

Autoimmune diseases, inherited disorders, infections and certain medication-related kidney injuries can also contribute to advanced kidney disease.

Identifying the original cause remains important even after ESRD develops because it can influence treatment, complications and transplant planning.

ESRD and Dialysis Options

When kidney replacement therapy becomes necessary, dialysis is one of the major treatment approaches.

There are two principal forms of dialysis.

Hemodialysis

Hemodialysis circulates blood through a dialysis machine and a filter called a dialyzer.

The process helps remove:

• Waste products

• Excess fluid

• Certain excess minerals

Hemodialysis may be performed in a dialysis center or, for selected patients, at home.

The schedule and duration are individualized.

Peritoneal Dialysis

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

Dialysis fluid is introduced into the abdominal cavity through a catheter. Waste and excess fluid move into the dialysis solution, which is then drained and replaced.

Peritoneal dialysis can provide an alternative to hemodialysis for appropriately selected patients.

Is Dialysis a Cure for ESRD?

No.

Dialysis performs some of the functions that failing kidneys can no longer perform, but it does not restore normal kidney function or repair permanently damaged kidneys.

Patients receiving dialysis may still require:

• Medicines

• Dietary management

• Fluid management

• Blood-pressure monitoring

• Anemia management

• Mineral and bone disease management

• Regular laboratory testing

• Ongoing nephrology follow-up

The treatment plan is adjusted according to the patient's clinical needs.

Kidney Transplantation for ESRD

A kidney transplant is another major treatment option for appropriately selected patients with kidney failure.

During transplantation, a functioning donor kidney is placed into the recipient's body to perform kidney functions.

A transplant may come from:

• A living donor

• A deceased donor

Transplant evaluation involves detailed medical assessment to determine whether transplantation is appropriate and safe.

A transplant is a treatment for kidney failure rather than a simple cure. Recipients need lifelong follow-up and anti-rejection medicines to protect the transplanted kidney.

Can a Person Receive a Kidney Transplant Before Dialysis?

In selected patients, preemptive kidney transplantation may be possible before dialysis begins.

This depends on factors such as:

• Rate of kidney-function decline

• Overall health

• Transplant eligibility

• Availability and suitability of a donor

• Evaluation by a transplant center

Early discussion with a nephrologist and transplant team can allow time for appropriate evaluation and preparation.

What Is Conservative Management in ESRD?

Not every patient chooses dialysis or is medically suitable for transplantation.

Conservative kidney management focuses on treating symptoms and complications without dialysis or transplant.

It may include:

• Symptom control

• Medication management

• Fluid and dietary planning

• Blood-pressure management

• Treatment of anemia and other complications

• Emotional and supportive care

• Advance-care planning

This approach can be considered for selected patients, particularly when other serious health conditions or personal treatment goals make dialysis inappropriate or undesirable.

The decision should be made through a detailed discussion between the patient, family and healthcare team.

Why Early ESRD Planning Matters

Waiting until a medical emergency occurs before discussing kidney replacement therapy can make treatment planning more difficult.

Patients approaching kidney failure may benefit from early education about:

• Hemodialysis

• Peritoneal dialysis

• Home dialysis where available

• Kidney transplantation

• Conservative management

Early preparation may also allow time to plan appropriate dialysis access and complete transplant evaluation.

What Is Dialysis Access?

Patients preparing for hemodialysis may need a reliable way to connect their bloodstream to the dialysis machine.

Possible access types include:

• Arteriovenous fistula

• Arteriovenous graft

• Dialysis catheter

When long-term hemodialysis is expected, access planning should ideally occur before dialysis becomes urgently necessary.

The appropriate access depends on the patient's veins, health status, expected dialysis needs and clinical circumstances.

ESRD and Diet

Nutrition becomes particularly important in advanced kidney disease.

Dietary recommendations may involve individualized management of:

• Sodium

• Potassium

• Phosphorus

• Protein

• Fluid

• Calories

There is no single ESRD diet that is suitable for everyone.

Dietary needs can change after dialysis begins, and patients should follow the plan recommended by their nephrologist and renal dietitian.

Avoid extreme dietary restrictions or unverified kidney-detox diets.

ESRD and Fluid Intake

Fluid management is often important when kidney function is severely reduced.

Some patients with ESRD produce very little urine and may need a prescribed fluid limit.

Drinking excessive water does not improve failing kidney function and can worsen fluid overload in susceptible patients.

The correct fluid allowance depends on:

• Urine production

• Dialysis schedule

• Body weight

• Blood pressure

• Heart function

• Degree of fluid retention

• Other medical conditions

Follow the individualized plan provided by the kidney-care team.

ESRD and Anemia

Healthy kidneys contribute to red blood cell production through hormone production.

Advanced kidney disease can reduce this function and contribute to anemia.

Patients may experience:

• Fatigue

• Weakness

• Reduced exercise tolerance

• Breathlessness

• Difficulty concentrating

Doctors may evaluate hemoglobin and iron status and provide treatment when indicated.

ESRD and Bone and Mineral Problems

Advanced kidney disease can disturb the body's balance of calcium, phosphorus and parathyroid hormone.

Over time, these changes can affect bones and cardiovascular health.

Monitoring may include:

• Calcium

• Phosphorus

• Parathyroid hormone

• Vitamin D-related measurements when appropriate

Treatment is individualized according to laboratory findings and kidney disease status.

Can ESRD Patients Still Live Active Lives?

Kidney failure can significantly change daily routines, but appropriate treatment can help many people continue family, work and social activities.

Dialysis schedules, diet, fluid restrictions, medications and medical appointments may require planning.

Physical activity may also be possible for many patients, depending on their overall health.

The aim of treatment is not only to manage laboratory values but also to support quality of life, independence and long-term health.

When Should an ESRD Patient Seek Urgent Medical Attention?

A person with advanced kidney disease should seek urgent medical care for symptoms such as:

• Severe breathlessness

• Chest pain

• Confusion

• Fainting

• Very little or no urine

• Severe weakness

• Persistent vomiting

• Rapidly worsening swelling

• Severe palpitations or suspected dangerous potassium abnormality

• High fever or signs of serious infection

Dialysis patients should also promptly report problems involving their dialysis access, including significant bleeding, redness, swelling, pus or other signs of infection.

Frequently Asked Questions About ESRD Renal Disease

What does ESRD renal mean?

ESRD means end-stage renal disease, a term associated with kidney failure in which kidney function has become severely reduced and dialysis or kidney transplantation may be required.

Is ESRD the same as Stage 5 kidney disease?

ESRD is closely associated with Stage G5 CKD, but the terms are not identical in every context. Stage G5 generally refers to eGFR below 15 mL/min/1.73 m² for the appropriate duration or a patient already receiving dialysis.

What eGFR is considered ESRD?

An eGFR below 15 mL/min/1.73 m² is generally in the kidney-failure range. However, the decision to begin dialysis depends on the overall clinical situation rather than eGFR alone.

Does everyone with ESRD need dialysis?

People with established kidney failure may require dialysis or transplantation, but the exact treatment pathway depends on clinical circumstances, transplant eligibility and treatment preferences. Conservative management may also be considered for selected patients.

Can ESRD be reversed?

Established kidney failure caused by permanent chronic kidney damage is generally not reversible. However, a very low kidney-function result should be interpreted carefully because acute kidney injury can sometimes temporarily reduce kidney function. The underlying cause and duration need to be evaluated.

What are the main ESRD treatment options?

Treatment options include hemodialysis, peritoneal dialysis, kidney transplantation and, for selected patients, conservative kidney management.

Can an ESRD patient receive a kidney transplant?

Yes. Appropriately selected patients can be evaluated for kidney transplantation. A transplant evaluation determines whether surgery and long-term immunosuppressive treatment are suitable.

Is ESRD the same as acute kidney failure?

No. ESRD generally refers to advanced, permanent kidney failure, whereas acute kidney failure or acute kidney injury develops over a short period and may sometimes recover. Some patients with severe acute kidney injury require temporary dialysis while the kidneys recover.

Conclusion

ESRD renal disease refers to advanced kidney failure in which the kidneys can no longer adequately perform their essential functions. It is commonly associated with Stage G5 CKD and may require kidney replacement therapy.

Symptoms can include swelling, fatigue, itching, nausea, reduced urine output, muscle cramps, weakness and breathlessness, although symptoms vary considerably between individuals. Diagnosis requires assessment of kidney function and associated complications rather than relying on symptoms alone.

Treatment options include hemodialysis, peritoneal dialysis and kidney transplantation. Selected patients may also choose or be offered conservative kidney management focused on symptom control and quality of life.

Planning early for kidney replacement therapy can provide more time to understand treatment choices, prepare for dialysis when appropriate and explore transplant eligibility.
