I have been having symptoms of diabetes for awhile. My sister is diabetic and tested me. I have had several postprandial numbers well over 200 and one of 391. My fasting numbers are always over 100 and had some 126,127,153. Had fasting blood work along with lipid panel done last week. The nurse said my fasting level was 5.2 and showed normal lipid levels. But I am still experiencing symptoms and high postprandial numbers. Is it possible I can still be diabetic? Nurse said for me to stop checking my blood. That was her only advice. She said I'm not diabetic since my morning fasting test showed normal. I'm confused. Any help would be appreciated.
