What Causes Itching in Dialysis Patients

2013-05-01 14:38

What Causes Itching in Dialysis PatientsA majority of dialysis patients notice that they experience skin itching. Some of them feel itchy all the time, while others may complain their skin itches more severely during or just after dialysis treatment. However, what causes itching in dialysis patients?

We know people with end-stage kidney disease have a higher incidence of skin itching than the general population, while dialysis also raises this high incidence. Therefore, patients’ ESRD, dialysis treatment and phosphorus metabolic disorder all can contribute to their skin problems.

In ESRD also known as renal failure, large part or nearly all of kidney function has been damaged. Then, more and more wastes and purified protein derivative build up in the blood. So high level of various wastes are likely to cause skin problem including itchy skin and dry skin.

High phosphorus level is another cause, because dialysis is commonly used to remove small molecular substances including uric acid, creatinine, blood urea nitrogen, water, etc, but can’t eliminate all phosphorus from the body. Over time, too much phosphorus will build up in the blood and cause itching skin easily.

In rare cases, this skin problem is due to allergies. If patients notice itching occurs at the beginning of dialysis treatments, they may have an allergy to the blood tubing, dialyzer or other elements associated with dialysis.

Because different patients have various conditions, doing a diagnosis to make sure the root cause is very necessary for the following treatment. If you are suffering from severe skin itching that happens all the time, the high build up of wastes may be the root cause. In this situation, kidney function improvement is the most effective treatments to solve both your skin problem and many other symptoms. The key to achieve this purpose is to increase damaged kidney cells’ self-curative ability and nourish them. As for the later two causes, correct medicines, diet and some changes in dialysis treatment can help ease itching effectively.
