Understanding

Dialysis

Dialysis is a life-saving treatment for individuals with kidney failure, a condition where the kidneys are no longer able to filter waste products and excess fluids from the blood effectively. This procedure replicates many of the kidneys' functions, helping to maintain balance in the body and prevent complications associated with kidney failure.

What is Dialysis?

Dialysis is a medical procedure that removes waste products and excess fluids from the blood when the kidneys are no longer able to perform these functions naturally. It is typically required for patients with end-stage renal disease (ESRD) or severe chronic kidney disease (CKD).

​

There are two main types of dialysis:

​

  1. Hemodialysis

  2. Peritoneal Dialysis

Types of Dialysis

Choosing the Right Type of Dialysis

The choice between hemodialysis and peritoneal dialysis depends on several factors, including the patient’s medical condition, lifestyle and personal preferences.

 

Our healthcare provider can help determine the best option based on individual needs and circumstances.

Dialysis requires significant lifestyle adjustments, but many patients continue to lead active, fulfilling lives. Key aspects of managing life with dialysis include:

​

  • Diet and Nutrition: Following a special diet to manage fluid and electrolyte balance.

  • Medications: Taking prescribed medications to control blood pressure, anemia, and other complications.

  • Regular Monitoring: Attending scheduled dialysis sessions and medical appointments to monitor health status and adjust treatments as necessary.

  • Support Systems: Engaging with  healthcare providers to address the emotional and psychological aspects of living with dialysis.

Living with Dialysis

Dialysis is a critical treatment for individuals with kidney failure, offering a way to manage the condition and maintain quality of life. Understanding the types of dialysis, their benefits and how to live with dialysis can empower patients and caregivers to navigate this challenging journey effectively.

1. Hemodialysis:

​

Hemodialysis uses a machine and a filter, known as a dialyzer, to clean the blood. The process involves:

​

  • Access to the Bloodstream: This is typically achieved through a fistula (an artery and vein joined together under the skin) or a graft (a plastic tube that connects an artery and a vein).

  • Dialysis Process: Blood is pumped from the body to the dialyzer, where it passes through a semipermeable membrane. Waste products and excess fluids move from the blood into a dialysis solution (dialysate) and are removed from the body.

  • Frequency: Hemodialysis is usually performed three times a week, with each session lasting about 3-5 hours.

2. Peritoneal Dialysis:

​

Peritoneal dialysis uses the lining of the abdomen (the peritoneum) as a natural filter. The process involves:

​

  • Access to the Abdomen: A catheter is surgically placed in the abdomen.

  • Dialysis Process: Dialysis solution is infused into the abdominal cavity through the catheter. Waste products and excess fluids pass from the blood vessels in the peritoneum into the dialysate. After a dwell time, the used solution is drained and replaced with fresh dialysate.

 

Types of Peritoneal Dialysis:

​​

Continuous Ambulatory Peritoneal Dialysis (CAPD): Manual exchanges are done several times a day.

​

Automated Peritoneal Dialysis (APD): A machine performs exchanges overnight while the patient sleeps.
