Why would my BUN creatinine ratio be high?

A high BUN value may be caused by a high-protein diet, Addison’s disease, or tissue damage (such as from severe burns), or from bleeding in the gastrointestinal tract. High BUN-to-creatinine ratios occur with sudden (acute) kidney problems, which may be caused by shock or severe dehydration.

What does a BUN reading of 25 mean?

The normal range of blood urea nitrogen (BUN) is between 7 and 20 mg/dL or 2.5 and 7.1 mmol/L. There may be slight variations between labs. A decline in kidney function can cause an increase in BUN levels. There is no definite value of BUN that would diagnose kidney failure.
