What is Hemodialysis?

Hemodialysis is a treatment that uses a machine called a dialyser (artificial kidney) to filter the blood outside the body. Blood is drawn from the patient, cleaned through the dialyser to remove waste products and excess fluid, and then returned to the body. This process mimics the kidneys' natural filtration and is typically performed three times a week for most patients.

Why is Hemodialysis Needed?

When chronic kidney disease advances to End-Stage Renal Disease (ESRD), the kidneys fail to adequately filter blood, leading to a buildup of harmful substances. Hemodialysis prevents complications such as fluid overload, high blood pressure, electrolyte imbalances, and uremia. It serves as a bridge to kidney transplantation or a long-term management option.

How the Hemodialysis Procedure Works

  1. 1
    Vascular Access: Blood access created via AV fistula, graft, or catheter (AV fistula preferred for long-term use).
  2. 2
    Connection: Two needles inserted into the access site — one draws blood out, one returns cleaned blood.
  3. 3
    Filtration: Blood passes through the dialyser across a semi-permeable membrane, removing wastes via diffusion and excess fluid via ultrafiltration.
  4. 4
    Duration: Each session lasts 3–5 hours, usually 3 times per week.
  5. 5
    Monitoring: Vital signs, blood pressure, and weight closely monitored throughout each session.

Preparation and Lifestyle Considerations

  • Create vascular access well in advance (AV fistula ideally 2–3 months before starting)
  • Follow dietary guidelines on fluid, potassium, phosphorus, and sodium intake
  • Maintain hygiene around access sites to prevent infections
  • Monitor weight daily to track fluid removal needs
  • Attend all scheduled sessions to avoid complications from missed treatments

Frequently Asked Questions

How often do I need hemodialysis?

Most patients require sessions three times a week, but frequency can be adjusted based on kidney function and overall health.

Is hemodialysis painful?

The procedure itself is not painful. Needle insertion may cause brief discomfort, but local numbing is often used and many patients relax during sessions.

What should I eat before a dialysis session?

Follow your dietitian's advice. Typically limit fluids and avoid high-potassium foods. A light meal is usually fine.

Can I travel while on hemodialysis?

Yes, with planning. Arrange treatments at dialysis centres near your destination and carry medical records.

What happens if I miss a dialysis session?

Missing sessions can lead to fluid overload, high potassium, or serious issues. Contact your doctor immediately if you must miss one.

How long can someone stay on hemodialysis?

Many live productive lives for years or decades on hemodialysis, especially with good care and a possible future transplant.

What are common side effects during treatment?

Some experience low blood pressure, cramps, or nausea. These are managed by adjusting fluid removal or medications.

Can hemodialysis be done at home?

Yes, home hemodialysis is an option for suitable patients after training, offering more flexibility.

How is vascular access cared for?

Keep the site clean, avoid injury, check for thrill/bruit daily, and report any changes like swelling or redness promptly.

Does hemodialysis replace all kidney functions?

It replaces filtration but not hormone production or other roles, so medications and monitoring remain important.

What blood tests are done regularly during dialysis?

Tests monitor haemoglobin, electrolytes, calcium, phosphorus, and dialysis adequacy (like Kt/V or urea reduction ratio).

Is hemodialysis covered by insurance?

Many policies cover it as essential treatment. Our team can assist with documentation.
