Introduction

Being told that you or a loved one needs dialysis can feel overwhelming and frightening. Many people have questions such as:

What exactly is dialysis?
Will dialysis cure kidney disease?
How will life change?
Can I continue working?
What foods can I eat?
How long will I need dialysis?

Although starting dialysis is a major life change, many people continue to live active and meaningful lives while receiving treatment.

This guide explains:

How the kidneys work
Why dialysis becomes necessary
Different types of dialysis
Lifestyle changes
Nutrition and self-care
Financial and emotional considerations

Understanding the Kidneys

The kidneys are two bean-shaped organs located near the middle of the back.

They perform many essential functions:

Remove waste products from the blood
Remove excess fluids
Maintain electrolyte balance
Help control blood pressure
Produce hormones
Support red blood cell production
Maintain bone health

Healthy kidneys work continuously to keep the body in balance.

What Is Kidney Failure?

Kidney failure occurs when the kidneys can no longer adequately perform their functions.

This may happen suddenly or gradually.

Acute Kidney Injury (AKI)

A sudden loss of kidney function.

Possible causes include:

Severe infection
Dehydration
Certain medications
Major surgery
Trauma

Some people recover completely.

Chronic Kidney Disease (CKD)

A gradual decline in kidney function over months or years.

Common causes include:

Diabetes
High blood pressure
Polycystic kidney disease
Glomerulonephritis
Recurrent kidney infections

End-Stage Kidney Disease (ESKD)

The most advanced stage of kidney failure.

At this stage, treatment often involves:

Dialysis
Kidney transplantation
Conservative management

What Is Dialysis?

Dialysis is a treatment that performs some of the functions normally carried out by healthy kidneys.

Dialysis helps:

Remove waste products
Remove extra fluid
Maintain electrolyte balance
Reduce symptoms caused by kidney failure

Dialysis can be life-saving.

Does Dialysis Cure Kidney Disease?

No.

Dialysis is not a cure.

It is a treatment that helps replace some kidney functions when the kidneys cannot work adequately.

Some people may eventually receive a kidney transplant.

Others may require dialysis long term.

Why Is Dialysis Needed?

When the kidneys stop functioning properly, harmful substances can build up in the body.

Without treatment, this may lead to:

Severe illness
Organ damage
Life-threatening complications

Dialysis helps remove these substances.

Signs and Symptoms of Kidney Failure

Symptoms may include:

Fatigue
Weakness
Nausea
Vomiting
Swelling of feet and legs
Loss of appetite
Itching
Difficulty breathing
Difficulty concentrating
Reduced urine output
High blood pressure

Some people may have few symptoms until kidney disease becomes advanced.

When Is Dialysis Started?

The decision depends on:

Kidney function
Symptoms
Blood test results
Overall health

Doctors consider multiple factors rather than a single laboratory value.

Types of Dialysis

There are two main types:

Hemodialysis
Peritoneal Dialysis

Both aim to remove waste and excess fluids.

Hemodialysis Explained

Hemodialysis uses a machine and a special filter called a dialyzer.

The process involves:

Blood leaves the body.
The machine filters waste and excess fluid.
Cleaned blood returns to the body.

Where Is Hemodialysis Performed?

Dialysis centers
Hospitals
Home settings in selected situations

How Often Is Hemodialysis Done?

Schedules vary, but many people undergo dialysis several times each week.

Your healthcare team will determine the appropriate schedule.

What Is Vascular Access?

A vascular access is needed to allow blood to flow to the dialysis machine.

Common types include:

Arteriovenous (AV) Fistula

Usually the preferred long-term access.

AV Graft

Used when a fistula is not possible.

Central Venous Catheter

May be used temporarily.

Peritoneal Dialysis Explained

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

A special fluid is placed into the abdomen through a catheter.

Waste products move into the fluid, which is later drained.

Types of Peritoneal Dialysis

Continuous Ambulatory Peritoneal Dialysis (CAPD)

Performed manually several times each day.

Automated Peritoneal Dialysis (APD)

Performed using a machine, often during sleep.

Advantages of Peritoneal Dialysis

Greater flexibility
Home-based treatment
Fewer visits to dialysis centers
More independence for some people

Choosing the Right Type of Dialysis

The choice depends on:

Medical condition
Lifestyle
Home environment
Personal preferences
Availability of support

The healthcare team can help determine the most suitable option.

Preparing for Dialysis

Preparation may involve:

Blood tests
Imaging studies
Creating vascular access
Vaccinations
Education sessions
Nutritional counseling

What Happens During Hemodialysis?

A typical session may involve:

Weight measurement
Blood pressure monitoring
Connection to the machine
Continuous monitoring
Completion of treatment
Reassessment before leaving

What Happens During Peritoneal Dialysis?

The process usually includes:

Filling the abdomen with dialysis fluid.
Allowing the fluid to remain for a period.
Draining the fluid.
Repeating the cycle as prescribed.

Diet and Nutrition on Dialysis

Nutrition plays a vital role in maintaining health and quality of life.

Diet recommendations vary between individuals.

Protein

People on dialysis often need adequate protein.

Sources include:

Eggs
Fish

Foods that may require monitoring include:

Processed foods
Certain dairy products
Soft drinks

Excess fluid may cause:

Swelling
Difficulty breathing
High blood pressure
Heart problems

Muscle cramps
Fatigue
Infection
Access problems

Infection of the abdomen (peritonitis)
Catheter problems
Hernias
Weight gain
