It is important to manage your blood glucose levels as close to normal as possible to avoid complications in the long term. Testing your blood glucose levels regularly allows you to have instant feedback to help you manage and learn about your diabetes.
What your blood glucose levels mean:
Range Levels Comments Low blood glucose less than 3.5 mmol/L Hypoglycaemia # Normal range 4-8 mmol/L during the day Appropriate glycaemic control Ideal control 4-6 mmol/L before meals
Up to 8mmol/L after meals*
Appropriate glycaemic control Fair control 6-7 mmol/L before meals
Up to 11mmol/L after meals*
Associated with minimal development of long term complications Poor control 7mmol/L or more before meal
11.1 mmol/L or more after meals*
Associated with the development of long term complications. More active treatment and close management is required
*after meals indicates two hours after the start of the meal
# Hypoglycaemia can occur in people who are on insulin and certain types of oral hypoglycaemic tablets that lower your blood glucose levels, e.g. medications in the sulphonylurea drug group. Hypoglycaemia can also occur when meals are late, missed, or when not enough carbohydrates are eaten, or when you have extra or unplanned physical activity.
