Hello doctor,

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.



Welcome to icliniq.com.

It appears that you do not have diabetes but just impaired fasting glucose, or in other words, you might develop diabetes in the next few years if you do not have a proper diet control. I would suggest that you control your diet by eating low fat, low carbohydrate, drink plenty of water, and exercise moderately by walking for 30 minutes a day. Recheck your HbA1C levels every six months. Do not worry. Hope you find my advice of some benefit. Good luck.

Thank you doctor,

I have attached my blood sugar reports for your better understanding.

I have seen the reports (attachment removed to protect patient identity). The reports confirm my previous diagnosis of impaired fasting glucose. Have a good diet control and exercise regularly. Good luck.
