When the sugar rises over 200mg/dL, it tells you that blood sugar is not well controlled. There are many reasons that the blood sugar may be elevated before breakfast. Among the reasons, could be: expired medications, your dose is not sufficient, or your evening snack(s) have more carbohydrates than anticipated. Consult with your provider to the best corrective action.
