I'm diabetic since 6 years & hypertensive since 2 years.
Diabetes remains under control but bp sometimes get uncontrolled
My serum
creatinine level on 11th May was 0.9 mg/dl & on 21st September it came 1.1 mg/dl. (Lab normal : 0.72-1.25).Had low protein diet & adequate hydration the day before test
However,blood urea & serum potassium came normal at every time
Urine ACR done on 1st August was also normal
USG (KUB+PVRU) done on 4th April was also normal
Took Chlordiazepoxide (Librium) 25 mg twice a day for 1 month which was stopped 1 week before the test
Took a bottle of beer daily for 20 days which was stopped 4 days before the test
What might be the cause of such significant rise ?
