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 is a bad BUN creatinine ratio?
The ideal ratio of BUN to creatinine falls between 10-to-1 and 20-to-1. Having a ratio above this range could mean you may not be getting enough blood flow to your kidneys, and could have conditions such as congestive heart failure, dehydration, or gastrointestinal bleeding.
What does a creatinine level of 200 mean?
120-200. Mild to moderate kidney failure – but in someone with little muscle, 200 could sometimes mean more severe kidney failure. 300+ Moderate to severe kidney failure. Most dialysis patients have creatinine measurements over 300 all of the time.
Does drinking more water lower creatinine levels?
Drinking more water could lower the serum creatinine level, but does not change kidney function. Forcing excessive water intake is not a good idea.
What does a BUN creatinine ratio of 15 mean?
Normal or intrarenal (ATN) Normal range. Can also be ATN. Some sources say the normal range is 10-15:1. Renal damage causes reduced reabsorption of BUN, therefore lowering the BUN:Cr ratio.
What are symptoms of high BUN?
In addition, your BUN levels may be checked if you are experiencing symptoms of later stage kidney disease, such as:
- Needing to go the bathroom (urinate) frequently or infrequently.
- Recurring fatigue.
- Swelling in your arms, legs, or feet.
- Muscle cramps.
- Trouble sleeping.

What causes high bun and creatinine levels?
Diabetes or hypertension can be the causes of heightened levels of BUN and creatinine. Even some medications, like antibiotics, anti-inflammatory medicines, and gout medication, affect these levels. High protein diet and heart failure are some other causes.
