Beginning last summer, for the first time, I had a blood test come back reporting high levels of Urea Nitrogen (BUN) and BUN/Creatinine Ratio. I just had a follow up appointment, and the levels were high again. I made sure I was hydrated. I had actually fallen asleep early the night before, and woke up dehydrated... but made up for it, drinking several glasses of water off and on hours before the test.. Again, the doctor called and stated "I was a little dehydrated" with BUN of 29 (should be 7-25) and a BUN/Creatinine Ratio of 29 (should be 6-22).
I've read about possible causes.. I'd say my diet is moderate protein intake, though it's not much different than in years past, if any different at all. I do have urinary retention, but this is a side effect of an antidepressant medication I'm on... and I've been this way for many, many years as well. My father has low kidney function, along with many other conditions... So I'm just keeping a close eye on this. I go back on Wednesday... Any thoughts???
