What is dialysis - Smashing Health Guide

Dialysis is a treatment for individuals whose kidneys are coming up short. There are two types of dialysis, hemodialysis and peritoneal dialysis, both of which perform normal kidney functions by filtering out waste and excess fluid from the blood.

What is dialysis?

Dialysis is a treatment for individuals whose kidneys are coming up short. When a person has kidney failure, the kidneys do not filter the blood properly. As a result, waste and toxins accumulate in the bloodstream. Dialysis does the work of the kidneys, eliminating waste and excess fluid from the blood.

Who needs dialysis?

People with kidney failure, or end-stage renal disease (ESRD), may need dialysis. Injuries and conditions such as high blood pressure, diabetes and lupus can affect the kidneys, leading to kidney disease.

Some people develop kidney problems for no apparent reason. Kidney failure can be a long-term condition or can occur suddenly (acutely) after a serious illness or injury. This type of kidney failure can go away as people recover.

There are five stages of kidney disease. In stage 5 kidney disease, doctors consider you to be in the final stage of kidney disease (ESRD) or kidney failure. At this point, the kidneys perform about 10% to 15% of their normal function. People may need dialysis or a kidney transplant to stay alive. Some people get dialysis while waiting for a transplant.


Kidney function

The kidneys are part of the urinary system. These two bean-shaped organs are located below the rib cage on each side of the spine. They cleanse the toxins from the blood, returning filtered and nutrient-rich blood.

Excess waste and water form urine, which travels from the kidneys to the bladder. The kidneys also help regulate blood pressure.


Types of dialysis

There are two ways to get dialysis:

  • Hemodialysis.
  • Peritoneal dialysis


Hemodialysis

In the case of hemodialysis, a device removes blood from the body, filters it through a dialyzer (artificial kidney) and returns the cleaned blood to the body. This 3 to 5 hour process can take place in a hospital or dialysis center three times a week.

You can also have hemodialysis at home. Home treatments may need four to seven times a week for fewer hours per session. People can choose to have hemodialysis at home at night while they sleep.


Comparison of the two types of dialysis

Hemodialysis and peritoneal dialysis both filter out unwanted waste from the body. Depending on the type of dialysis treatment that the person chooses, they may also have the option of doing dialysis at home or in a dialysis center.


Peritoneal dialysis

Peritoneal dialysis uses the blood vessels in the lining of the abdomen - the body's natural filter - along with a solution called dialysate to filter toxins. With this method, a peritoneal catheter serves as an access to the abdomen, and the blood never leaves the body. Peritoneal dialysis at home can be performed with a device or manual, at home, at work or even while traveling.


Hemodialysis

Hemodialysis filters the blood using a dialysis machine or a dialyzer. Once the person is connected to the device through hemodialysis access, the blood flows into the device, is filtered and returned to the body.

Hemodialysis is performed either at home or in a dialysis center. Hemodialysis at home can be performed in the comfort of your own home, either with the help of a care partner or alone. Hemodialysis in the center is performed by a team of qualified nurses and technicians.

In the case of hemodialysis, the duration and frequency of treatment depend on the doctor's prescription and the place of treatment.

Hemodialysis at home can be performed 5-6 days a week for 2 1/2 to 3 hours each, 3 days a week for 3-5 hours, or 6-8 hours during sleep each night. or two nights. Longer treatments or a different number of weekly treatments may also be needed, depending on the patient's condition.

Hemodialysis in the center is usually done 3 times a week for 3-5 hours during the day or 8 hours for nocturnal hemodialysis.

In the case of peritoneal dialysis, the duration of treatment will depend on whether to choose ambulatory continuous peritoneal dialysis (CAPD) or automatic peritoneal dialysis (APD):

Dialysis treatment is prescribed by a specialist. Together, your doctor will discuss treatment options and determine what is appropriate for each patient. If it is decided that the patient should undergo dialysis, the doctor will prescribe the duration and frequency of treatment according to health needs.
