BUN 5 mg/dL in your blood test results
You received your blood test result with a BUN value of 5 mg/dL. This analysis helps you to check if your BUN value is within normal range.
Your BUN value of 5 mg/dL is too low. A good Blood urea nitrogen (BUN) is usually between 7 and 20 mg/dL.
Increase your Blood urea nitrogen (BUN) by 2 mg/dL to be within normal range.
Causes
Because BUN is produced when your body breaks down protein, a low-protein diet can cause low BUN levels. Low protein can cause fatigue, poor muscle tone, poor concentration, and low immunity. Overhydration can also cause low BUN levels. In some cases, low BUN levels are a sign of liver disease. When your liver doesn't function properly, it may not break down protein and produce BUN. Liver disease can cause malnutrition, jaundice, fatigue, muscle aches, and other issues.
Treatment & Medication
If you have low BUN levels because of a low-protein diet, the best treatment is to incorporate more protein-rich foods into your meals. If liver disease is the cause of your low BUN levels, your doctor will focus on treating that issue. Treatments for liver disease include medications, lifestyle changes, and surgery.
Useful Information
A blood urea nitrogen test, or BUN test, shows how well your kidneys are functioning. Your liver breaks down the proteins you eat and produces urea nitrogen, which is released into your blood. Healthy kidneys should remove the BUN and leave only a small amount in the blood. Abnormal BUN levels show that something is wrong with your kidneys.
