REAL WORDS

"The best thing I did early on was start a care journal. When my brain felt foggy and everything was coming at me fast, I wrote it all down — questions, notes, how I was feeling. Over time, it became my reference point as I found my new routine."
-Lucy, Caregiver & Professional Note-Taker

Your First Steps

What Usually Happens Next

After diagnosis, most people move through an intense early phase. It’s not linear — and it’s not meant to be mastered all at once.

You’ll meet with your nephrologist and care team, learn about options, schedule catheter placement, and begin training. What makes this phase challenging isn’t difficulty — it’s the volume of information.

You’re allowed to slow the pace and come back to questions as your confidence grows.

You Are Still You

A diagnosis changes the path – not the person walking it.
People living with PD work, rest, travel, raise families, build routines, and find joy in everyday moments.

You don’t have to be brave today.

You just have to be here – and you already are.

This chapter doesn’t define the whole story.

What is Peritoneal Dialysis

Understanding the Treatment — Without the Overwhelm

Peritoneal Dialysis is a form of dialysis that works inside the body using your peritoneum (the lining of your abdomen) as a natural filter. A special fluid helps pull waste and extra water out — gently and steadily.

How it Works

How Peritoneal Dialysis Actually Works

A catheter sits in your abdomen as your access point. Dialysis fluid flows in, your peritoneum filters waste and extra water into that fluid, then it drains out and gets replaced. This cycle repeats several times a day to keep your body in balance.

  • Soft catheter placed in your abdomen
  • Fluid exchanges happen on your schedule
  • Your body stays balanced throughout the day

Know Your Options

What Makes Peritoneal Dialysis Different

Peritoneal Dialysis is often chosen because it happens at home, on a schedule that fits your life. Many people find the steadier rhythm easier on their body and mind. You stay independent while having your care team close by. In many parts of the world, peritoneal dialysis is often the first option offered — helping people maintain more flexibility, independence, and quality of life as they adjust.

  • Care happens at home, in a space that feels familiar
  • You build a routine that fits your life
  • Treatment is needle-free and designed for comfort

Clarity

What Peritoneal Dialysis is Not

Let’s clear up a few common misconceptions — so you can move forward with more clarity and less pressure.

COMMON CONCERNS

What PD is Not

  • Not limited to the hospital
  • Not one-size-fits-all
  • Not something you’re expected to master on day one

WHAT PEOPLE EXPERIENCE

Confidence Builds with Time

It gets easier as you go — with support, repetition, and real-life experience.

Your Options

Peritoneal Dialysis vs. Hemodialysis

Most people hear about two main dialysis options: peritoneal dialysis (PD) and hemodialysis (hemo). Both are effective. Both are valid. Choosing one does not lock you in forever.

Know the Difference

The Big Difference, in Plain Terms

  • Hemodialysis is often done at a dialysis center on a set schedule (and in some cases, at home).
  • Peritoneal dialysis is typically done at home and offers more flexibility.

One isn’t better — they’re simply different ways of supporting your body.

Many people change modalities over time.
Your treatment can evolve as your life, health, and needs change.
This decision is about what fits right now.

You Have Options

What Matters Most

The right choice supports your health – and fits your life, your routine, and what matters most to you.

Support Your Health

Fits Into Your Daily Life

Treatment works best when it fits into your day — your schedule, your routines, and the life you want to keep living.

Feels More Manageable In Time

What feels overwhelming at first becomes more familiar — and with the right support, confidence grows step by step.

Your New Rhythm

Peritoneal Dialysis at Home, What Daily Life Can Look Like

Your Home

Routines That Work For You

Over time, you find a rhythm that fits your day - not something that takes it over.

Support Is Always There

Your care team is there to guide you, answer questions, and support you as you learn and adjust.

A Realistic, Reassuring Truth

Life Finds a New Shape

Questions

Real concerns deserve real answers. Your care team is here to help.

PD fluid does remove some protein, which is why your care team monitors this closely. They can adjust your treatment and diet to help maintain balance. Ask your nephrologist what your protein levels look like and what you need to focus on.

Yes. You may need to plan around your exchange schedule or find positions that feel comfortable with your catheter. Many people find their intimacy returns once they adjust. Talk openly with your partner and your care team about what feels right.

Getting on the transplant list starts with a referral from your nephrologist to a transplant center for an evaluation. This process looks at your overall health, readiness for transplant, and any steps needed to move forward. Your care team can help guide you through the process and timing that’s right for you.
For a clear overview of how transplant listing works, including evaluation steps and what to expect, visit the American Kidney Fund transplant resources. 

Some people explore living donation as part of the transplant process. Becoming a donor is a personal decision that involves medical evaluation, education, and informed consent. Transplant centers provide donors with their own care teams to ensure safety, privacy, and support throughout the process. If you’d like to learn how living donation works and what donors can expect, the American Kidney Fund offers clear, donor-focused information.  

Many people on PD continue to urinate, especially early on. This is actually helpful because it means your kidneys are still working. Over time, urine output may decrease. Your care team will monitor this and explain what's normal for you.

The exchanges themselves shouldn't hurt, though you may feel pressure or fullness in your abdomen. Some discomfort is normal at first as your body adjusts. If something feels sharp or wrong, tell your care team right away. Pain isn't something you have to accept.

Yes. Many people travel locally and internationally on PD. You'll need to plan ahead, arrange supplies, and coordinate with your care team. It takes preparation, but it's absolutely possible. Ask your team about travel resources and what you need to arrange.

Trust your instincts. If something feels off—pain, fever, cloudy fluid, or just a gut feeling—contact your care team. They'd rather hear from you than have you wait and worry. Your body knows things. Listen to it.

No. You need a clean, dry space for exchanges, but it doesn't have to be a dedicated room. A corner of your bedroom, bathroom, or kitchen works fine. Many people set up a small station with their supplies. Your space is yours to arrange.
