Understanding blood glucose ranges is an important part of diabetes self-management.
This page provides 'normal' blood sugar ranges as well as blood sugar ranges for adults and children with type 1 diabetes, type 2 diabetes, and blood sugar ranges to determine diabetes in people.

Ranges of recommended target blood glucose levels
The NICE recommended target blood glucose levels for adults with type 1 diabetes, type 2 diabetes, and children with type 1 diabetes are listed below.
Furthermore, the International Diabetes Federation's target ranges for people who do not have diabetes are stated.
The table serves as a general guide. You should aim for an individual target set by your healthcare team.

Blood sugar levels in normal and diabetic people
Normal blood sugar levels for the vast majority of healthy people are as follows:
- When fasting, 4.0 to 5.4 mmol/L (72 to 99 mg/dL) [361]
- 7.8 mmol/L (140 mg/dL) and higher 2 hours after consuming
- Diabetes patients should aim for the following blood sugar levels:
4 to 7 mmol/L before meals for people with type 1 or type 2 diabetes
After meals, people with type 1 diabetes should have less than 9 mmol/L and people with type 2 diabetes should have less than 8.5 mmol/L.
Blood sugar levels used to diagnose diabetes.
The following table lays out the criteria for diagnoses of diabetes and prediabetes.
