Dialysis is a life-saving medical procedure that helps individuals with kidney failure. By mimicking the functioning of healthy kidneys, dialysis ensures the removal of waste products and excess fluids from the body. If you or someone you know is undergoing dialysis or may need it in the future, it’s essential to understand how this process works. In this blog post, we will address some frequently asked questions about dialysis.

What is Dialysis?

Dialysis is a treatment that performs the functions of healthy kidneys when they fail. It aids in removing waste, salt, and excess water from the body to maintain the proper balance of electrolytes and keep blood pressure under control.

Who Needs Dialysis?

Dialysis is necessary for individuals whose kidneys have lost their ability to function properly. This mainly applies to patients with end-stage renal disease (ESRD) or acute kidney injury (AKI). Patients suffering from diabetes, high blood pressure, or other conditions affecting kidney function may also require dialysis.

How Does Dialysis Work?

There are two primary types of dialysis: hemodialysis and peritoneal dialysis.

Hemodialysis

In hemodialysis, blood is removed from the patient’s body and passed through a dialyzer, a machine that acts as an artificial kidney. The dialyzer filters waste products and excess fluids from the blood, which is then returned to the patient’s body. This procedure usually takes place three times a week for three to four hours per session.

Peritoneal Dialysis

In peritoneal dialysis, a sterile cleansing fluid is introduced into the patient’s abdomen through a catheter. The fluid, known as dialysate, sits in the peritoneal cavity and draws waste and excess fluids from the blood through the peritoneal membrane. The dialysate is then drained, removing the toxins from the body. Peritoneal dialysis is a daily procedure performed by the patient at home or work.

What Are the Differences Between Hemodialysis and Peritoneal Dialysis?

  • Hemodialysis is typically performed in a hospital or dialysis center, whereas peritoneal dialysis can be done in the comfort of one’s home.
  • Hemodialysis requires a vascular access point, usually created through the insertion of a catheter or the creation of an arteriovenous fistula or graft. Peritoneal dialysis only requires the placement of a catheter into the abdomen.
  • Hemodialysis is performed for several hours only a few times a week, while peritoneal dialysis is done every day, usually during the night.

Dialysis is a critical procedure for individuals with kidney failure. Understanding how dialysis works allows patients and their families to adapt to this lifestyle change. Whether it is hemodialysis or peritoneal dialysis, both methods provide relief to patients and help them lead a better quality of life. If you or a loved one requires dialysis, consult with healthcare professionals to determine the best approach to meet your specific needs.

Remember, dialysis is just one part of the treatment plan for kidney failure. A healthy lifestyle, proper medication, and regular monitoring are equally essential for managing this condition effectively.
