With these test results, being overweight, and your family history, probably you have diabetes -- or at least pre-diabetic. See your doctor and take it from there. Good luck.

You can reduce your risk of getting diabetes by losing at least 10% of your body weight and exercising 150 minutes/week. Consult a nutritionist for diabetes prevention diet. Wish you good health!
