What Causes Low BUN levels in blood?
A low BUN value may be caused by a diet very low in protein, by malnutrition, or by severe liver damage. Drinking too much liquid may cause overhydration and cause a low BUN value. Women and children may have lower BUN levels than men because of how their bodies break down protein.
What is considered a low BUN level?
In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But normal ranges may vary, depending on the reference range used by the lab, and your age. Ask your doctor to explain your results. Urea nitrogen levels tend to increase with age.
What are the symptoms of low BUN?
Symptoms of liver and kidney disease
- frequent urination, especially at night.
- change in urine volume.
- decreased need to urinate.
- a burning sensation during urination.
- brown or red urine that appears foamy.
- pain, especially in the area near the kidneys (flank region)
- muscle cramps.
- numbness in the hands and feet.
What is a concerning BUN level?
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.
How do you treat low BUN levels?
Proper hydration is the most effective way to lower BUN levels. A low-protein diet can also help lower BUN levels. A medication wouldn’t be recommended to lower BUN levels. However, abnormal BUN levels don’t necessarily mean you have a kidney condition.
Is a BUN level of 5 bad?
The BUN is roughly one-half of the blood urea . Normal human adult blood should contain between 5 to 20 mg of urea nitrogen per 100 ml (5 to 20 mg/dL) of blood, or 1.8 to 7.1 mmol urea per liter .
Is a low BUN level bad?
Abnormally low levels of BUN can be a sign of malnutrition, lack of protein in the diet, and liver disease. Therefore, other tests included in a panel test like the comprehensive metabolic panel may provide helpful information for understanding the significance of low blood urea nitrogen.
Is a BUN level of 7 Bad?
The normal BUN level is between about 7 and 21 milligrams per deciliter (mg/dL). Unless this level is greater than 60 mg/dL, it may not help your healthcare provider measure your kidney health. A better measure is the ratio of BUN to creatinine found in your blood.
What happens if blood urea is low?
Low urea levels are not common and are not usually a cause for concern. They can be seen in severe liver disease or malnutrition but are not used to diagnose or monitor these conditions. Low urea levels are also seen in normal pregnancy. Urea levels increase with age and also with the amount of protein in your diet.
When should I be concerned about BUN levels?
The normal BUN level is between about 7 and 21 milligrams per deciliter (mg/dL). Unless this level is greater than 60 mg/dL, it may not help your healthcare provider measure your kidney health.
What are symptoms of a 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.
Can exercise increase BUN levels?
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. Rehydration will normalize these values.
Is a BUN level of 12 bad?
Understanding Your Results. Your result will be a number that measures how much BUN is in your blood. The range considered normal is between 7 to 20 milligrams per deciliter.
Is a BUN level of 27 bad?
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 level of BUN requires dialysis?
A blood urea nitrogen (BUN) level of 75 mg/dL is a useful indicator for dialysis in asymptomatic patients, but one that is based on studies with limitations. Different parameters, including absolute and relative indicators, are needed.
