Monitoring your blood glucose level which is known as self testing is an essential part of managing your diabetes. Checking your blood sugar helps you avoid low blood glucose levels (hypoglycemia) and high blood glucose levels (hyperglycemia). When you check your blood glucose level it helps you better understand how exercising, what you eat, and what stress does to your blood glucose levels. If your blood glucose levels are good it shows how well your medication is working. When checking your blood glucose it helps your doctor make your care plan to keep your blood glucose levels under control. Speak to your doctor to find out how often you need to check your blood glucose levels. For example it could be before and after you eat or before or after physical activity. Your doctor may also have you check it if you feel low and after you treat the low blood glucose level. If you check your blood glucose levels you will be able to steer clear of diabetes related problems such as heart disease, stroke, high blood pressure, high cholesterol, blindness, kidney disease, and skin problems.
