A member asked:

How does bun and creatinine gets elevated due to dehydration? kindly explain how?

A doctor has provided 1 answer

Concentration: Simplest way, if you have lets say 100 particles in 5 liter of fluid, the concentration is 20 per liter. If you now have only 3 liter of fluid, the concentration is now 33.3.

A member asked:

45, Female. Can you interpret these numbers for me. BUN 22, Serum Creatinine is 1.17, EGFR is 56, Chloride is 108, AG ratio is 2.3. Can dehydration cause the elevation in the numbers or should I be concerned about my kidney function?

My husband is diabetic. He had a random urine after a fast so was dehydrated. The urine creatinine was 390, albumin 39 so the ratio was normal at 10. Could being dehydrated have caused the high numbers? His plasma creatine and bun were normal?

My BUN was 20 today. Can dehydration cause it to be higher? Mine has always been on low end. Creatinine is normal, no other symptoms or abnormal tests. I have barely been drinking a bottle of water per day for quite a while?
