Hi I'm new to this website! I was diagnosed with kidney damage about 8 years ago. Last year, my kidney function was at 54%. As of this year (Oct. 17) my kidney function has dramatically decreased to 38%. My Nephrologist believes it could be from a medication I've been taking. Fenoglide(Fenofibrate). Has anyone else had this type of problem? And is 38% a not so bad reading? Also, when you have CKD how much water should you be drinking?
