What is Dialysis?

Dialysis is a medical procedure that helps people with kidney failure by removing waste products and excess water from their blood. When the kidneys are not working properly, they cannot filter these substances out of the blood, which can lead to a buildup of toxins in the body.

Dialysis can be performed in two ways: hemodialysis and peritoneal dialysis. Hemodialysis is the more common type of dialysis and involves using a machine to filter the blood. Peritoneal dialysis uses the patient's own peritoneum (the lining of the abdomen) to filter the blood.

Dialysis is a lifesaving treatment for people with kidney failure. It can help them to live longer and healthier lives. Let's explore the two main types of dialysis, hemodialysis and peritoneal dialysis, in more detail.

What is Dialysis

Dialysis is a lifesaving treatment for people with kidney failure.

  • Blood filtering treatment
  • Removes waste and excess water
  • Two main types: hemodialysis and peritoneal dialysis
  • Hemodialysis uses a machine
  • Peritoneal dialysis uses the patient's peritoneum
  • Dialysis helps people live longer and healthier lives
  • Can be performed in a hospital or at home

Dialysis is a complex medical procedure, but it is essential for people with kidney failure to survive. By understanding the basics of dialysis, you can better support your loved ones who are undergoing this treatment.

Blood filtering treatment

Dialysis is a blood filtering treatment that helps people with kidney failure by removing waste products and excess water from their blood. When the kidneys are not working properly, they cannot filter these substances out of the blood, which can lead to a buildup of toxins in the body. Dialysis helps to prevent this buildup by filtering the blood and removing the harmful substances.

There are two main types of dialysis: hemodialysis and peritoneal dialysis. Both types of dialysis work by filtering the blood, but they do so in different ways.

Hemodialysis is the more common type of dialysis. It involves using a machine to filter the blood. The machine is connected to the patient's bloodstream through two needles, one in an artery and one in a vein. The blood flows through the machine, where it is filtered and cleaned. The filtered blood is then returned to the patient's body through the vein.

Peritoneal dialysis is another type of dialysis that uses the patient's own peritoneum (the lining of the abdomen) to filter the blood. A special solution is introduced into the peritoneal cavity, and the waste products and excess water from the blood diffuse across the peritoneum into the solution. The solution is then drained from the peritoneal cavity, taking the waste products and excess water with it.

Dialysis is a lifesaving treatment for people with kidney failure. It can help them to live longer and healthier lives. Dialysis is typically performed in a hospital or dialysis center, but it can also be done at home.

Removes waste and excess water

Dialysis helps to remove waste products and excess water from the blood. These substances can build up in the body when the kidneys are not working properly, leading to a number of health problems.

  • Urea

    Urea is a waste product that is produced when the body breaks down protein. High levels of urea in the blood can lead to fatigue, nausea, and vomiting.

  • Creatinine

    Creatinine is a waste product that is produced when muscles break down. High levels of creatinine in the blood can lead to muscle cramps, weakness, and fatigue.

  • Potassium

    Potassium is an electrolyte that is important for nerve and muscle function. High levels of potassium in the blood can lead to heart rhythm problems and muscle weakness.

  • Sodium

    Sodium is an electrolyte that is important for fluid balance in the body. High levels of sodium in the blood can lead to swelling, high blood pressure, and seizures.

  • Excess water

    Excess water in the body can lead to swelling, high blood pressure, and shortness of breath.

Dialysis helps to remove these waste products and excess water from the blood, preventing them from building up to dangerous levels. This helps to improve the patient's overall health and well-being.

Two main types: hemodialysis and peritoneal dialysis

There are two main types of dialysis: hemodialysis and peritoneal dialysis. Both types of dialysis work by filtering the blood, but they do so in different ways.

  • Hemodialysis

    Hemodialysis is the more common type of dialysis. It involves using a machine to filter the blood. The machine is connected to the patient's bloodstream through two needles, one in an artery and one in a vein. The blood flows through the machine, where it is filtered and cleaned. The filtered blood is then returned to the patient's body through the vein.

  • Peritoneal dialysis

    Peritoneal dialysis is another type of dialysis that uses the patient's own peritoneum (the lining of the abdomen) to filter the blood. A special solution is introduced into the peritoneal cavity, and the waste products and excess water from the blood diffuse across the peritoneum into the solution. The solution is then drained from the peritoneal cavity, taking the waste products and excess water with it.

Both hemodialysis and peritoneal dialysis are effective treatments for kidney failure. The type of dialysis that is best for a particular patient will depend on their individual needs and preferences.

Hemodialysis uses a machine

Hemodialysis is a type of dialysis that uses a machine to filter the blood. The machine is called a hemodialyzer, and it works by passing the patient's blood through a semipermeable membrane.

  • Blood flows through the machine

    The patient's blood is pumped out of their body and into the hemodialyzer. The blood flows through the hemodialyzer, where it is filtered.

  • Waste products and excess water are removed

    As the blood flows through the hemodialyzer, the waste products and excess water are removed. The waste products and excess water pass through the semipermeable membrane and into the dialysate solution.

  • Clean blood is returned to the body

    Once the blood has been filtered, it is returned to the patient's body. The clean blood is returned to the body through a vein.

  • Dialysis treatments are typically performed three times per week

    Hemodialysis treatments are typically performed three times per week, for three to four hours each treatment. The length of each treatment may vary depending on the patient's individual needs.

Hemodialysis is a lifesaving treatment for people with kidney failure. It helps to remove waste products and excess water from the blood, and it can help to improve the patient's overall health and well-being.
