What Is A Dangerous High BUN Level

What Is A Dangerous High BUN LevelBlood urea nitrogen (BUN) is one blood test used commonly to reflect kidney function just like serum creatinine. If BUN level is too high, it must indicate some dangerous conditions. Do you know what is a dangerous high BUN level?

What is blood urea nitrogen?

This test is used to indicate the content of urea in the blood, and urea is one terminal product of protein metabolism. Normally, kidneys are responsible for eliminating excessive urea out of the body via urine. Then, normal BUN level ranges from 9 to 20 mg/dl.

When high BUN level is considered to be dangerous?

If the production of urea increases abnormally or urea excretion amount declines, BUN level will rise. According to the underlying cause, the dangerous BUN levels are different from case to case.

When patients take in too much meat or rich-protein foods, patients' blood urea nitrogen will increase quickly. Besides, if patients suffer from severe dehydration for limited fluid intake or strenuous exercise, urine output will decline obviously, causing more urea to deposit in the blood. All of these problems can cause BUN level to increase quickly. In this condition, patients don't need to be worried. This is because prompt modifications of diet plan and lifestyle can make BUN level back to normal effectively.

However, if high BUN level is caused by kidney problem, patients should pay highly attention to their illness condition. In China, doctors determine patients' kidney disease has aggravated into uremic stage, when BUN level rises to 60 mg/dl. Then, patients should take some effective therapies such as dialysis, Blood Purification or Clear Blood Pollution Therapy to reduce their high BUN level.
