I've just been diagnosed with type 2 diabetes. What are the best times to use my glucose monitoring system? I'm supposed to check twice a day.
The best time of day to check your blood glucose is before meals, two hours after meals and at bedtime. This does not mean you will be checking seven times a day, but it does mean that when you pick a time, you will want it to be one of these. Each time of day gives you different information about your blood glucose level. Before breakfast readings tell you about what happened to your blood glucose overnight. Before lunch and supper tells you how well your blood glucose is doing throughout the day. Bedtime readings let you know how the dinner meal is affecting your blood glucose, while checking before and two hours after a meal also lets you know how different types of food affect your blood glucose. The typical pattern of checking recommended for people who are newly diagnosed is before breakfast and two hours after your largest meal. You may not always have to check twice a day, but at the beginning checking at least two times a day at various times will help you to learn about your own diabetes and how different activities, medication and food affect you.
