Welcome to Ask The Doctor.
Blood sugar variations can occur in normal people too. Fasting blood sugar of 126 mg/dl it is considered as diabetes and if blood sugar fasting is between 110-126 mg/gl, we call it Pre-diabetes or impaired fasting.
Your blood sugar levels seems normal to me.
You can get a glycosylated hemoglobin (HbA1c) done to be sure.
I hope it helps.
