What could be causing high creatinine levels in my blood?
My blood tests have been coming back showing high level of creatinine. I don't have kidney problems or diabetes that I know of. I've been checked for diabetes in the past. I drink a gallon of water or more everyday. I eat a very high protein diet and work out 1-2 hours a day. I have been using protein and creatine powder. What could be causing this? Also, my bladder seems to be very overactive. I have to urninate every half hour.
