High Blood Urea Level after Hemodialysis

2013-08-08 15:29

High Blood Urea Level after HemodialysisSome dialysis patients complain that their blood urea level is still high after hemodialysis. For example, some one finds her blood urea level was 147 but it was still 102 after dialysis. Why does blood urea level is still high after hemodialysis?

What is hemodialysis?

Hemodialysis is used to take over of kidneys’ job of purifying blood. During hemodialysis, patients are hooked up to dialyzer, and their blood flows a little bite at a time through this dialyzer. Once the blood is purified, it is returned to the body. In addition, hemodialysis mainly filters small molecular substances such as urea, creatinine and water.

Why does patients’ blood urea is still high after hemodialysis?

The above is the basic action principle of hemodialysis. Even though hemodialysis can help eliminate waste products, toxins and excess water from the blood, it still can’t work as effectively as kidney. This is because our kidneys work 24 hours one day, while hemodialysis is only done 3 times one week in most cases. These substances will build up in the body during dialysis session.

Additionally, not every hemodialysis can guarantee cleanse patients’ blood adequately and not all of waste products can be removed from the body at one dialysis treatment. These are all reasons for high urea acid after hemodialysis.

How to deal with this situation

Replacing hemodialysis with peritoneal dialysis or other blood purification methods such as plasma exchange and immune adsorption may be one choice. As for which one is suitable for you, it should depend on your individual condition. Besides, making a healthy diet including limiting the intake of purine, protein and sodium, and stopping some medicines that can inhibit the elimination of blood urea. What’s more, treatment that can help improve kidney function is also needed. With these methods, you can find your blood urea level is reduced obviously.
