From my reports are there any preventive measures I should take for diabetes?

Hello doctor,

I am a 40-year-old male. I am a vegetarian. I pursue an active lifestyle. I do not smoke or drink. I am a long distance endurance marathon runner. I also strength train three days a week and run two days a week. I got my sugar test, thyroid profile and vitamin D levels checked yesterday. I am attaching the detailed reports, summary as follows:

1. Blood Glucose (F) 89 mg/dL.
2. Blood Glucose (PP) 102 mg/dL.
3. Urine sugar (both in F and PP) not present.
4. HbA1C 5.8 percent.
5. Thyroid profile: T3(CLIA) 57 ng/mL, T4(FPIA) 6.38 ug/dL, TSH(CLIA) 1.81 uIU/mL.
6. Vitamin D (25 hydroxycholecalciferol) 26.97 ng/mL.

From the reference ranges, things seem to be fine. I just wanted to check with you for any precautions or preventive measures to be taken. Thanks.

Hello doctor,

Thanks a lot for such a fast feedback. Should I take it just once a week for two months? Any particular strength levels? Also, just wanted to get it reconfirmed from you. I am not diabetic right? Is everything fine with my sugar and HbA1C levels?
