Increased Level of Urea in the Blood
Urea is another compound found in the bloodstream which should be excreted in the kidneys during metabolism. You realize that when the kidney fails, it can’t excrete urea which causes the compound levels in the blood flow to increase and occupy other tissues in the blood. The body uses it in numerous body processes, but it becomes toxic if its level increases beyond the required level thus causing various complications to patients suffering from kidney failure. [2]
