This does not appear to be diabetes, especially given your hemoglobin A1C, which tells you your overall blood sugar control over the past 3 months. If you want to monitor this, you could have the hemoglobin A1C repeated in 3-4 months to see what the trend is. If you continue with your healthy lifestyle, this likely will not be a problem. Best of luck to you!

Technically yes. Visit this site for information on this topic: https://www.cdc.gov/diabetes/basics/getting-tested.html Regular aerobic exercise for 30 minutes/day, 5 days/week will help in controlling glucose. Wish you good health!
