What is your GFR?? And are you seeing a nephrologist? They can determine what is causing your kidneys not to function at their full capacity. It could be certain medications, diabetes, high blood pressure, etc. Also, anti-inflammatory meds like Ibuprofen and Aleve are not good for the kidneys. A below average GFR is not always bad... you just need to monitor it and it may go up. If it keeps dropping and dropping, thats when it becomes a concern.
not enough info..but a low GFR IS A SIGN OF CKD OR A STAGE OF RENAL FAILURE..WHATS THE GFR?? MINE IS GREATER THAN 60..IF WAS LESS THAN 60 FOR 3 CONSECUTIVE MONTHES THEN TESTING WOULD BEGIN..YOU DIDNT GIVE MUCH TO GO ON..ANYTHING LESS THAN 59 IS CKD..ANYTHING LESS IS RENAL DEPENDING ON OTHER FACTORS ALSO NEED MORE INFO TO EXPLAIN TO YOU!!!
