ESRD hemodialysis refers to the use of hemodialysis as a form of kidney replacement therapy for people with end-stage renal disease (ESRD), also called end-stage kidney disease.

When the kidneys become severely damaged, they may no longer adequately:

• Remove metabolic waste

• Eliminate excess fluid

• Maintain electrolyte balance

• Regulate acid-base balance

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

It does not completely reproduce every function of healthy kidneys, but it can help perform important filtration functions when native kidney function is severely reduced.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized assessment and management for patients with advanced kidney disease and dialysis-related needs.

What Is End-Stage Renal Disease?

ESRD generally refers to kidney failure in which kidney function is severely reduced and kidney replacement therapy or comprehensive conservative management is required depending on the patient's circumstances.

An eGFR below 15 mL/min/1.73 m² is commonly categorized as kidney failure, but eGFR alone does not automatically determine when dialysis should begin.

Doctors consider:

• Symptoms

• Fluid balance

• Potassium

• Acid-base status

• Nutritional status

• Uremic complications

• Urine output

• Overall health

• Patient preferences and treatment goals

Some people with very low kidney function may not need immediate dialysis if complications remain controlled.

Why Is Hemodialysis Used in ESRD?

Healthy kidneys continuously filter blood.

In ESRD, this filtration capacity becomes severely impaired.

Hemodialysis can help:

Remove Waste Products

Waste substances that accumulate because of reduced kidney filtration can be removed through dialysis.

Remove Excess Fluid

Dialysis can remove fluid when the kidneys cannot adequately eliminate it.

Help Control Electrolytes

Hemodialysis can help manage certain electrolyte abnormalities, including elevated potassium.

Improve Acid-Base Balance

Dialysis can help correct significant metabolic acidosis in appropriate patients.

These functions are important for maintaining internal physiological balance.

How Does Hemodialysis Work?

During hemodialysis, blood travels from the body through the dialysis circuit and into a dialyzer.

The process generally involves:

1. Blood leaves the body through a dialysis access.

2. A blood pump moves the blood through the dialysis machine.

3. Blood passes through the dialyzer.

4. Waste products and excess fluid move out of the blood.

5. Treated blood is returned to the body.

The dialysis prescription is individualized according to kidney function, body size, fluid status, laboratory findings and other clinical factors.

What Is Dialysis Access?

A reliable route into the bloodstream is necessary for conventional hemodialysis.

Common forms of access include:

Arteriovenous Fistula

An AV fistula connects an artery and vein, usually in the arm.

It is often preferred for long-term hemodialysis when suitable because it can provide durable access with appropriate care.

Arteriovenous Graft

A graft uses a synthetic or biological conduit to connect an artery and vein.

It may be considered when a suitable fistula cannot be created.

Dialysis Catheter

A temporary or tunneled catheter can provide vascular access.

Catheters may be useful in urgent situations or when permanent access is not yet available, but they can carry higher infection and complication risks than a well-functioning fistula or graft.

When Should Dialysis Access Be Planned?

Dialysis access planning should ideally begin before dialysis becomes an emergency when progressive kidney decline suggests that kidney replacement therapy may be needed.

Early planning can allow time for:

• Vascular assessment

• Fistula creation

• Fistula maturation

• Patient education

• Modality selection

• Transplant evaluation

Planning ahead can reduce dependence on emergency dialysis catheters in suitable patients.

How Often Is Hemodialysis Done for ESRD?

A common in-center hemodialysis schedule is three sessions per week, with each treatment lasting several hours.

However, the exact prescription varies.

Factors that may influence dialysis frequency and duration include:

• Remaining kidney function

• Body size

• Fluid gain between sessions

• Dietary intake

• Laboratory results

• Dialysis adequacy

• Medical condition

Home hemodialysis can provide different scheduling options for selected patients.

The dialysis team determines the appropriate prescription.

What Happens During an ESRD Hemodialysis Session?

Before dialysis, the healthcare team may check:

• Blood pressure

• Pulse

• Weight

• Fluid status

• Vascular access

• Symptoms

During treatment, the patient is monitored for:

• Blood-pressure changes

• Cramps

• Nausea

• Headache

• Access problems

• Other symptoms

After dialysis, weight and vital signs may be reassessed.

Patients should report unusual symptoms to the dialysis team.

What Are Common Side Effects of Hemodialysis?

Some patients experience symptoms during or after dialysis.

These may include:

• Low blood pressure

• Muscle cramps

• Fatigue

• Headache

• Nausea

• Dizziness

• Itching

• Feeling weak after treatment

Symptoms can have different causes.

For example, excessive or rapid fluid removal may contribute to low blood pressure or cramping.

The dialysis team can review the treatment prescription when symptoms occur repeatedly.

What Are Possible Complications of Long-Term Hemodialysis?

Long-term hemodialysis requires ongoing monitoring.

Potential complications include:

Vascular Access Problems

Fistulas, grafts and catheters can develop:

• Infection

• Narrowing

• Clotting

• Poor blood flow

Anemia

Kidney failure reduces erythropoietin production and can contribute to anemia.

Mineral and Bone Disorders

Abnormal calcium, phosphorus and parathyroid hormone regulation can occur in advanced kidney disease.

Cardiovascular Disease

People with ESRD have a high burden of cardiovascular complications, requiring comprehensive risk management.

Fluid Overload

Excess fluid between dialysis sessions can contribute to:

• Swelling

• High blood pressure

• Breathlessness

• Heart strain

Individual fluid and sodium recommendations are important.

What Should ESRD Patients Eat?

There is no single dialysis diet suitable for every patient.

Nutritional recommendations depend on:

• Potassium levels

• Phosphorus levels

• Residual kidney function

• Dialysis schedule

• Diabetes

• Body weight

• Nutritional status

• Other medical conditions

Depending on the individual situation, the dialysis team or renal dietitian may advise attention to:

Sodium

Excess sodium can increase thirst and fluid accumulation.

Potassium

Some dialysis patients need to limit high-potassium foods, particularly when blood potassium is elevated.

Phosphorus

Phosphorus management may involve dietary changes and, when prescribed, phosphate binders.

Protein

Unlike some non-dialysis CKD diets, people on maintenance dialysis often require adequate protein intake because dialysis can increase protein needs.

Protein restriction should not be undertaken without professional advice.

Fluids

Fluid intake may need to be limited depending on urine output and fluid accumulation.

Can ESRD Be Treated Without Hemodialysis?

Yes, hemodialysis is not the only kidney replacement option.

Depending on the patient's medical condition and preferences, options may include:

• Peritoneal dialysis

• Kidney transplantation

• Conservative kidney management

The appropriate approach should be discussed with a nephrologist.

Peritoneal Dialysis vs Hemodialysis

Peritoneal dialysis uses the lining of the abdomen as a membrane for exchanging waste and fluid.

Hemodialysis uses an external dialyzer.

The choice between modalities depends on:

• Medical suitability

• Home circumstances

• Lifestyle

• Support system

• Patient preference

• Previous abdominal surgery

• Vascular access considerations

• Local availability

There is no single dialysis modality that is suitable for every patient.

Kidney Transplantation for ESRD

For appropriately selected patients, kidney transplantation can provide a functioning donor kidney and may eliminate the need for ongoing dialysis after successful transplantation.

Transplant evaluation can include assessment of:

• Overall health

• Cardiovascular status

• Infection risks

• Cancer screening

• Blood group and immunological factors

• Surgical suitability

Not every patient is a transplant candidate, and evaluation is individualized.

Some patients may receive a transplant before dialysis, while others undergo dialysis before transplantation.

Conservative Kidney Management

Some patients with advanced kidney disease may choose or be advised to receive comprehensive conservative care rather than dialysis.

This approach can focus on:

• Symptom management

• Fluid and electrolyte control

• Blood-pressure management

• Anemia management

• Nutritional support

• Quality-of-life considerations

• Advance care planning

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

How Is Dialysis Adequacy Monitored?

Dialysis is not assessed simply by how a patient feels after a session.

The healthcare team may monitor:

• Urea reduction

• Kt/V or other adequacy measures

• Fluid status

• Blood pressure

• Electrolytes

• Nutritional status

• Anemia

• Vascular access function

• Symptoms

Regular laboratory testing and clinical assessment help determine whether the dialysis prescription remains appropriate.

What Is Dry Weight in Hemodialysis?

Dry weight is an estimated post-dialysis weight at which the patient has an appropriate fluid balance without significant signs of fluid overload or excessive fluid removal.

Determining dry weight is not simply a matter of choosing a fixed number.

The dialysis team considers:

• Blood pressure

• Swelling

• Breathing

• Weight trends

• Symptoms during dialysis

• Other clinical findings

Dry weight may need adjustment as the patient's condition changes.

Why Does Fluid Management Matter in ESRD?

People with very little urine production may accumulate fluid between dialysis sessions.

Excess fluid can lead to:

• Swelling

• High blood pressure

• Breathlessness

• Pulmonary edema

• Increased cardiovascular strain

Limiting excessive sodium can help reduce thirst and fluid accumulation in appropriate patients.

Fluid recommendations should be individualized according to residual urine output and the dialysis plan.

ESRD and High Potassium

Potassium can accumulate when kidney function is severely impaired.

Dangerously high potassium can affect the heart and may become life-threatening.

Management can involve:

• Dietary changes when appropriate

• Medication review

• Potassium-lowering medicines in selected situations

• Adequate dialysis

• Urgent medical treatment when severe

Do not make major dietary restrictions without knowing your blood potassium level and receiving professional advice.

ESRD and Anemia

Anemia is common in advanced kidney disease.

Reduced kidney production of erythropoietin is an important contributor.

Management may include evaluation and treatment of:

• Iron deficiency

• Blood loss

• Inflammation

• Other nutritional deficiencies

• Kidney-related erythropoietin deficiency

Selected patients may require iron therapy or erythropoiesis-stimulating agents.

Treatment is based on laboratory findings and clinical circumstances.

What Happens If a Dialysis Session Is Missed?

Missing dialysis can allow:

• Fluid to accumulate

• Potassium to rise

• Waste products to build up

• Blood pressure to worsen

The consequences depend on remaining kidney function, fluid intake, diet and overall health.

If a dialysis session is missed, the dialysis center or treating nephrologist should be contacted promptly for individualized instructions.

Do not independently double a subsequent treatment.

When Should an ESRD Patient Seek Urgent Medical Care?

Immediate medical attention may be needed for:

• Severe breathlessness

• Chest pain

• Fainting

• Severe weakness

• Confusion

• Very high potassium

• Severe swelling

• Persistent vomiting

• Very low blood pressure

• Fever or chills with a dialysis catheter or other access

• Sudden loss of access function

• Significant bleeding from dialysis access

Patients should have a clear emergency plan from their dialysis team.

ESRD Hemodialysis and Daily Life

Many people receiving maintenance dialysis continue to work, travel, exercise and participate in family activities, although schedules and physical capacity may need adjustment.

Daily care commonly involves:

• Following the dialysis schedule

• Taking prescribed medicines

• Monitoring fluid intake

• Following individualized dietary recommendations

• Protecting vascular access

• Attending blood tests and medical appointments

The treatment plan may evolve as the patient's health changes.

Can Exercise Be Done During Hemodialysis?

Physical activity may be beneficial for many dialysis patients, but the type and intensity should be individualized.

Exercise programs may include:

• Walking

• Light resistance exercises

• Stretching

• Supervised intradialytic exercise in selected centers

Patients should discuss exercise plans with their healthcare team, especially if they have cardiovascular disease, severe anemia or other limitations.

Long-Term Kidney Care for ESRD Patients

ESRD management extends beyond dialysis itself.

Important areas include:

• Blood-pressure control

• Diabetes management

• Cardiovascular risk reduction

• Anemia treatment

• Bone and mineral management

• Nutritional support

• Infection prevention

• Vascular-access care

• Medication review

• Transplant assessment when appropriate

• Psychosocial support

Regular nephrology follow-up helps coordinate these aspects of treatment.

Frequently Asked Questions

What is ESRD hemodialysis?

ESRD hemodialysis is a form of kidney replacement therapy that uses a dialysis machine and dialyzer to remove waste products and excess fluid when kidney function is severely impaired.

Is hemodialysis the only treatment for ESRD?

No. Depending on the patient's situation, treatment options may include hemodialysis, peritoneal dialysis, kidney transplantation or comprehensive conservative kidney management.

How many times a week is hemodialysis needed?

A common in-center schedule is three times weekly, with each session lasting several hours. The actual prescription is individualized.

Can a person with ESRD live a normal life on dialysis?

Dialysis can become part of a person's long-term routine, and many patients continue working, exercising and participating in daily activities. Individual experiences vary according to health, age, complications and treatment schedule.

What happens if too much fluid builds up between dialysis sessions?

Excess fluid can cause swelling, high blood pressure and breathlessness and may place additional strain on the heart and lungs. Fluid and sodium management are therefore important.

Can ESRD patients receive a kidney transplant?

Some patients with ESRD may be suitable for kidney transplantation after a comprehensive medical evaluation. Transplant eligibility varies between individuals.

What should I do if I miss dialysis?

Contact your dialysis center or nephrologist as soon as possible. Do not independently double your next treatment or make major fluid or medication changes.

Conclusion

ESRD hemodialysis is an important form of kidney replacement therapy for people whose kidneys can no longer adequately remove waste and excess fluid. Treatment uses a dialyzer to filter the blood and help control fluid, electrolyte and acid-base disturbances.

Successful long-term dialysis involves much more than attending dialysis sessions. Vascular-access care, fluid management, nutrition, anemia treatment, mineral-bone health, cardiovascular risk management and regular monitoring all play important roles.

For some patients, peritoneal dialysis, kidney transplantation or comprehensive conservative management may be appropriate alternatives or complements to hemodialysis.

If you or a family member has advanced kidney disease, a nephrologist can explain the available treatment pathways and help develop an individualized plan based on kidney function, symptoms, medical conditions and personal preferences.
