When your kidneys are no longer able to function properly, i.e., when they reach a stage of end-stage renal disease (ESRD, where there is no chance of recovery of your kidney functions), dialysis becomes a life-saving treatment.

But despite being a common procedure, many patients and families still wonder: Is dialysis safe? And increasingly, questions arise: Is it painful? Is it temporary?

Let’s unpack the safety aspects of dialysis and explore how good dialysis is important to maintain good health.

Understanding Dialysis: A Lifeline for Kidney Failure

Dialysis is a medical process that removes waste products, excess fluids, and toxins from the blood when the kidneys can no longer do so effectively. There are two main types:

  • Hemodialysis (HD): Blood is filtered through a machine (dialyzer) using a special filter and then returned to the body, usually done in hospitals.
  • Peritoneal Dialysis (PD): Uses the lining of your abdomen to filter blood inside your body, usually done at home on a daily basis.

Is Dialysis Safe?

Yes, dialysis is generally safe, especially when performed regularly under medical supervision. Millions of patients worldwide undergo dialysis and enjoy improved quality of life and extended life expectancy provided they follow the treatment as per their doctor’s prescription.

Is Dialysis temporary?

This is a very frequently asked question. If your doctor has informed you that your kidney disease is not reversible and you have reached end-stage kidney disease, then dialysis is a lifelong treatment.

The other option is to go for a kidney transplant, which is the best treatment if your doctor considers you to be suitable for a transplant.

Is it painful?

Dialysis is generally a painless procedure. It involves placing needles in your fistula to access blood and circulate it through the dialysis machine. Some patients may experience some pain while placing needles, which can be minimized by applying a cream to the fistula site

However, as with any medical procedure, dialysis carries some side effects, including

  • Low blood pressure (hypotension)
  • Muscle cramps
  • Infections (especially at catheter or access sites)
  • Fatigue

How can these risks be minimized?

Most of these risks can be minimized by

  • Undergoing regular thrice-weekly treatment or sometimes twice weekly, depending on your doctor’s recommendation,
  • having a skilled healthcare team looking after you
  • Strict adherence to diet and fluid restriction plans
  • Have a detailed consultation with your doctor every month
  • Taking regular medications as advised
  • Regular 30–45 minutes of exercise per day, which is mandatory
