When BUN and creatinine are both elevated on a blood test it can be an indication of a kidney problem. A high protein diet, antibiotics, anti-inflammatory medications, and gout medications all can cause high BUN and creatinine.Dehydration, kidney stones, kidney disorders or bleeding from the digestive tract such as from a bleeding ulcer can also cause elevated values of these tests. Any test result should be correlated clinically.Consult a doctor for more queries and assistance. Do keep me posted.
Best luck and regards!
