In brief: Bad high BUN levels?

A high BUN by itself rarely gives any information.
Blood urine nitrogen (BUN) is a product of protein (p) metabolism. Pt with a low p intake will have low bun's compared to anothers with a high p intake with the same renal function. If your BUN and creatinine are elevated with high sodium and chloride levels, dehydration may be the cause. If not, renal failure may be present. Ask your physician.
