Decrease in flow.: Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body. Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not intrinsic kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal-reversible.

Many causes: Blood tests called BUN (blood urea nitrogen) and cr (creatinine) are often checked to help evaluate kidney function. The normal bun/cr ration is about 10:1 to 15:1. Some of the more common causes of an elevated bun/cr ratio are: dehydration, GI bleeding, increased protein intake, small amount of muscle mass, increased muscle breakdown.

Depends: Need to know if level is high from poor blood flow to kidney (pre-renal), intrinsic kidney trouble (intra-renal) or blockage (post-renal). Most common kidney problems in us are from high blood pressure and diabetes. Control those diseases and creatinine should behave itself.

Diabetes and creatin: Normal level of creatinine in blood is 0.6 to 1.2mgmdiabetes effects kidneys if the diabetes is not well controlled, and causes elevation of creatonine level.It is very difficult to reduce the level, but if you control biabetes and keep BP normal you can prevent it from getting worse, if it is too high over six then dialysis may be indicated and will bring the level down.

Between 0.5-1.2: The typical reference ranges for serum creatinine are 0.5 to 1.0 mg/dl for women and 0.7 to 1.2 mg/dl for men. Look for refernce values from the particular lab.

Upper limit : Creatinine of 1.2 is the upper limit of normal. More important is for you see your estimated glomerular filtration rate. Creatinine levels depend primarily on renal function, muscle mass and to some extent on state of hydration. You should discuss this result with your doctor at your next visit, .
