Are high levels of creatinine and blood sugar signs of renal insufficiency?
Patient: Hello, I am 52 y.o. white female. Recent lab results show my Creatinine level at .93 mg/dl. My Dr. is saying I have renal insufficiency; my a1c is 5.4 and fasting blood sugar was 100, he says I am pre-diabetic, I feel he is being a little too aggressive with diagnoses? Doctor: Hi,  If blood sugar level goes above 100 and below 126 than it is called pre diabetic. I am not in favour to label your case as pre diabetic.  However you need to get checked your fasting and post prandial blood sugar again after few weeks to check control in sugar. Meanwhile take low fat and low sugar diet with active exercise. Your creatinine is within limit.  Hope I have answered your question. Let me know if I can assist you further.  Regards, Dr. Parth Goswami, General & Family Physician
