Could A Unhealthy Diet Have Caused A Rise In BUN And Creatinine Levels?

had blood test my BUN 37, creatinine 2.2. prior to blood test, was dehydrated from drinking diet coke only, on a high protein diet, and used motrin about 2/3 times a week. i had a sonogram which showed no kidney abnormalities. going for a repeat blood and 24 hour urine, next week. could these factors made my levels rise?? can they go down?? i have been off motrin, eating little protein, no more diet coke, and drinking lots of water.
