What causes elevated BUN and creatinine?

Dehydration generally causes BUN levels to rise more than creatinine levels. This causes a high BUN-to-creatinine ratio. Kidney disease or blockage of the flow of urine from your kidney causes both BUN and creatinine levels to go up.

Should I worry about high 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 happens if creatinine levels are high?

Elevated creatinine level signifies impaired kidney function or kidney disease. As the kidneys become impaired for any reason, the creatinine level in the blood will rise due to poor clearance of creatinine by the kidneys. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys.

What is an excessively high BUN creatinine ratio?

Results that are higher than this range mean there is an excess of BUN in the blood, which could mean your kidneys are not getting the proper blood flow. An excessively high ratio could also reveal conditions such as congestive heart failure, gastrointestinal bleeding, or severe dehydration.

What level of BUN indicates kidney failure?

If your BUN is more than 20 mg/dL, your kidneys may not be working at full strength. Other possible causes of an elevated BUN include dehydration and heart failure.
