If your blood glucose level is above 200 mg/dl, you need to take insulin to reduce blood sugar. If your blood glucose level is below 75 mg/dl, you will need to swing into action and get some sugar into your system. In general, good blood glucose target numbers are:
• 90-115 mg/dl in the morning when you wake up
• Under 150 mg/dl two hours after eating
Or wherever your doctor says they should be!
