I am a 60 year old working woman, and my weight is 176 pounds. I am not diabetic, but my recent reports showed my fasting blood sugar level to be 105 mg/dL and HbA1C was 6.2 %. After seeing the report, I got scared, so I redid the test after a week. This time, my fasting blood sugar was 143 mg/dL and postprandial was 103 mg/dL. I am anxious, so please tell me that how come a nondiabetic patients sugar level is lower on one day and another day, it jumped to 143 mg/dL. What should I do now? Thank you.
