What does normal BUN and high creatinine mean?

Check for severe dehydration. 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.

What are normal BUN and levels?

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 is the normal range of bun and creatinine?

What should my bun be at 24 mg / dL?

Your BUN value of 24 mg/dL is too high. A good Blood urea nitrogen (BUN) is usually between 7 and 20 mg/dL. Lower your Blood urea nitrogen (BUN) by 4 mg/dL to be within normal range. High BUN levels are usually caused by a problem with your kidneys.

Losing some weight if overweight. Weight loss can improve your kidney health and decrease creatinine levels [ 20 ]. Again, disbalance between BUN and creatinine is often due to a serious medical condition and it is important to address it.

What causes elevated BUN levels?

The following factors can lead to elevated BUN levels: kidney damage, failure, or disease. dehydration. shock. urinary tract blockages or disease. gastrointestinal bleeding. heart attack. heart failure.

What causes high bun?

High values A high BUN value can mean kidney injury or disease is present. Many medicines may cause a high BUN. A high BUN value may be caused by a high-protein diet, Addison’s disease, tissue damage (such as from severe burns), or from bleeding in the gastrointestinal tract.
