Starting haemodialysis: what to expect before, during and after your first session

A practical, evidence-based guide to preparing for haemodialysis, understanding the session, and knowing what to ask your kidney care team.

Starting haemodialysis: what to expect before, during and after your first session

Being told you may need haemodialysis can bring practical questions alongside the medical ones. What happens at the first visit? How long does a session take? What should you bring? Knowing the usual steps can make it easier to have a focused conversation with the kidney care team.

This guide describes common haemodialysis arrangements. Your own plan, schedule and preparation depend on your health, access type and prescription, so confirm instructions with your treating team.

What haemodialysis does

In haemodialysis, blood passes through a filter called a dialyser and returns to the body. The treatment helps remove waste and extra fluid when kidneys cannot do enough of this work. It supports kidney function but is not a cure for kidney failure.

A clinician prescribes the treatment based on individual factors, including test results, body size, remaining kidney function, symptoms, access and other health conditions. The schedule and settings are not interchangeable between patients.

Before the first session

The team reviews your medical history, medicines, recent tests, symptoms and vascular access. Bring referral notes, discharge summaries, current medication names and recent kidney results when available. Tell staff about allergies, previous dialysis, infections, recent procedures and any change in how you feel.

  • Confirm the branch, appointment time and how early to arrive.
  • Ask whether you should eat, drink or take medicines as usual; do not change medicines without your prescriber's advice.
  • Ask which records and identification to bring.
  • Discuss transport and a contact person in case you feel unwell after treatment.
  • Request an itemised explanation of the session fee and any likely separate charges.

If you have a fistula or graft, ask the team how they want it assessed before treatment. If you have a catheter, follow the care instructions given by your clinical team; do not adjust dressings or lines yourself.

During a typical session

Staff check observations and the dialysis access, connect the prescribed blood lines, and monitor the treatment. The dialyser filters the blood while the machine controls the treatment according to the prescription. Staff should explain what they are doing and how to get their attention.

Some people read, rest or listen to audio during treatment. Tell staff promptly about discomfort, nausea, cramps, dizziness, chest symptoms, breathlessness or anything that feels unusual. The duration and frequency are set for the individual; online examples are not a substitute for your own prescription.

After the session

The team disconnects the circuit, checks the access and takes post-treatment observations as needed. You may feel tired; tell staff if symptoms persist or are severe. Ask how results and future appointments will be communicated, and whom to contact between sessions.

Keep a simple record of appointments, questions, symptoms and medicine changes to discuss at reviews. Do not alter fluid intake, diet or medicines based on a general article.

Questions worth asking

  • Who is responsible for my kidney care plan and how do I reach them?
  • What access do I have, and what changes should I report immediately?
  • What is my individual schedule and what should I do if I miss a session?
  • Which medicines should I take on treatment days?
  • What does the quoted session fee include, and what is billed separately?
  • How are lab tests, reviews and complications handled?

For Life Centre enquiries, check the current price list and ask the team which parts of your care may be charged separately. Wherever possible, request an itemised explanation before proceeding.

Common questions

Questions about this topic

How long is a first haemodialysis session?

It depends on the clinician's prescription and your circumstances. Ask the treating team for the planned duration; do not rely on a general online estimate.

Can I eat or take my medicines before dialysis?

Instructions vary with the treatment and your medicines. Ask your kidney care team what to do; do not stop or change prescribed medicines on your own.

What should I bring to dialysis?

Confirm with the centre. Useful items often include referral and recent medical records, a medicine list, identification and anything the centre has specifically asked you to bring.

Does haemodialysis cure kidney failure?

No. Haemodialysis replaces some kidney functions and is one treatment option. A kidney specialist can explain the options appropriate to you.
