Thanks for your question.
BUN refers to the blood urea nitrogen level.
This is a metanolite of proteins in the body.
Your BUN is mildly elevated which is likely from dehydration.
Adequate oral fluid intake will be helpful.
This is nothing serious and I do not think your doctor ignored that.
But your did not think it important to address.
Hence please do not worry.

Hmmm. I was fasting, because I had blood drawn for a lipid panel at the same time. But I deliberately drank a lot of water beforehand because (a) I was advised to do so and (b) I've learned over the years that it's easier for them to hit my veins if I do. So I very much doubt that I was dehydrated. Does this change your answer at all? Thank you
my answer still remains the same.
Thank you very much!
Although you drank fluids, fasting itself can cause midly elevated BUN.
Kidney disease can cause this but your creatinine level is normal.
So kidney disease is unlikely.
