In certain patients levels of Blood Urea Nitrogen (BUN) and Creatinine may rise above permissible limits and reach dangerous limits due to various reasons. This happens when the kidneys do not filter out the toxins which condition is called renal failure. It may be due to functional or structural changes of the kidney tissues. When BUN and Creatinine rise to a certain limit, hemodialysis is carried out, which is a procedure in which the blood is cleansed of toxins through a machine, replacing work that the kidneys normally do. Dialysis is done primarily to provide an artificial replacement for lost kidney function due to renal failure. Decision to carry out dialysis depends on many factors.
Normal levels of Creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dl) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females. The normal range for BUN is 7 to 20 milligrams per deciliter (mg/dL). At certain places it is mentioned as 7 – 25 mg/dl for adults.
Chronic causes of renal failure include poorly controlled diabetes, high blood pressure and glomerulonephritis. Side effects of certain medicines can also cause renal failure.
Once renal failure has occurred, orthodox medical system has only dialysis to offer. In advance cases transplant of kidney is the last option whereas homeopathy has the medicines that can improve and restore the kidney functions considerably and gradually and reduce the levels of BUN and Creatinine to normal limits restoring the natural function of the kidney. We have done it in several cases.
