If your kidneys are not working well, the urea nitrogen will stay in the blood. Normal blood contains 7-20 mg/dl of urea. 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.

What does a BUN level of 62 mean?

Normal BUN levels for adults over 60 are slightly higher than normal levels for adults under 60. Higher BUN levels can indicate: heart disease. congestive heart failure.

What happens if BUN is high?

High values

A high BUN value can mean kidney injury or disease is present. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure.

Is a BUN of 27 bad?

This can be greatly, and potentially dangerously, elevated by strenuous exercise. Dehydration associated with exercise may cause elevation of BUN and creatinine, two aspects of a kidney test. The BUN may be markedly elevated in the presence of severe dehydration; the creatinine may be mildly elevated.

Do BUN levels fluctuate?

So to recap, BUN levels fluctuate, while creatinine is removed at a constant rate and its blood levels are usually stable. That’s why the BUN/Creatinine ratio can be used to check for issues such as dehydration, kidney injury/disease, gut bleeding, and other problems .

Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m2 in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
