Most charts are more concerned with fasting and postprandial readings. While trying to keep my searches focused on children, I found this at
Blood Sugar Monitoring under the heading
Diabetes In Children:Numbers To Aim For
Here are the normal glucose levels for people without diabetes:
- Before breakfast: 70-110
- Before lunch, supper, and bedtime snack: 70-120
- One hour after meals: 140 or less
- Two hours after meals: 120 or less
It doesn't address bedtime numbers.
There is a chart with bedtime numbers at the bottom of
this page, but it is referring to children already diagnosed and using insulin.
