Kidney Dialysis

What is kidney dialysis?

Kidneys are responsible for filtering wastes from the blood. When kidneys are damaged, wastes and fluid build up in the body, resulting in swelling, high blood pressure, blood urine and so on. Dialysis provides an artificial replacement for lost kidney function, which will discharge the wastes and fluid from the body. Though it can not cure kidney disease, it is a way to save your life.

When do patients require kidney dialysis?

Generally speaking, when your illness develops into the end stage of kidney disease or when you have lost 85% to 90% of your kidney function, it is necessary for you to take dialysis.

What types of dialysis are there?

There are two main types of dialysis:
- Hemodialysis. It makes use of a machine to filter your blood. You have to go to a special clinic for treatments several times a week. It can eliminate the micro-molecular harmful substances, but the middle molecular and macromolecular substances still exist in your body, which will do further damage to your kidneys.
- Peritioneal dialysis. It makes use of peritoneum to filter you blood. You can stay at home for treatment several times a day. Moreover, it costs less than hemodialysis. But because the fenestra in peritoneum is bigger than semipermeable membrane in the hemodialysis, more nutrient will lose.

What are the side effects of dialysis?

- Itchy skin. It may be due to the accumulation of phosphrus.
- Low blood pressure. It may be due to the inadaptability to dialyzate or the rapid ultrafiltration.
- Muscle cramp. It may be due to oxygen deficit or low sodium or insufficient blood circulation in tissues.
- Infection. It is common for dialysis patients, because the bacteria is vey susceptible to invade into your body through the access connecting the inside and outside of the body.
- Nausea and vomit. It may be caused by dialyser reaction, polluted dialysate or abnormal component of electrolytes.
- Other side effects, such as diarrhea, headache and so on.
