To be sure, ask your doctor how often you should check your blood glucose. If you are treating your diabetes through diet and exercise or oral medication, diet and exercise, you should probably check your blood glucose level at least twice daily. If you take insulin, check your blood glucose four times daily. This will help you assess how well your meal and exercise plan and medication are working to stabilize blood sugar. Blood sugar levels of 180 two hours after eating or above 140 before eating are considered high.
