Why is it so important to monitor your blood sugar level?
Diabetics who have their condition under control have the best possible protection against emergencies and against diabetes-related secondary diseases. Medically speaking, controlling diabetes means keeping your blood sugar values in the near-normal range of 80 mg/dL to 120 mg/dL. If you inject insulin, you can achieve this goal only if you monitor your blood sugar levels at regular intervals.
In this case "under control" means that you regularly check your blood sugar levels and determine the insulin dose you need on the basis of these measured values. Regularly monitoring your blood sugar levels allows you to be actively involved in managing your diabetes. You can determine whether the therapy that was selected for you is the right one or whether the insulin dose needs to be adjusted.
Monitoring your blood sugar level also shows you how your blood sugar level is affected by diet, therapeutic measures (insulin, medication), sport, travel and illness and lets you take corrective actions immediately. You should speak to your doctor about the details of monitoring blood sugar levels.
