Brief Answer:
See below.

Detailed Answer:
Welcome and thank you for asking on HCM!
The normal ranges of blood sugar are 70-110 in the morning and before meals, and up to 140 after meals.
In people over 70 years old who should not risk for hypoglycemia it shouldn't be under 90 in the morning and after meals it is tolerated until 180.
Values such as 300 mg/dl or 500 mg/dl are too high.
Hope you are much better informed now regarding the blood sugar levels.
It will be a pleasure to answer further questions.
