Hello,
fasting blood sugar in the range of 120 - 130 puts you firmly in diabetic territory, as
does your hba1c of 7.4 which corresponds to an average
blood sugar level of about 180. These levels would already require medications.
Consider that normal fasting should be below 90 and normal hba1c is < 5.0.
Given your height and weight, you are not overweight. Further you have no family history of diabetes. Therefore, I believe you should be evaluated for adult onset type 1 diabetes.
