Hi, I recently just took a blood test and my BUN level is a 4. It was a six 2 years ago so it's dropping. My creating level is .70 so that's fine. My protein is high it's a 8.9. So I don't understand how my BUN would be low I thought it had to do with lack of protien. Ido t think I am over hydrated I only drink about 6-8 cups of water a day. Could this be dangerous and what can I do?
