Tracking and charting blood sugar levels is a good way to determine if a particular diabetes treatment plan is working, advises the American Diabetes Foundation. However, in order for the chart to be most effective, it must also record daily factors that affect blood glucose levels.
After measuring blood glucose levels, patients should write down their reading along with their level of physical activity, recently eaten foods and current levels of stress, according to the American Diabetes Foundation. Once these details are recorded, patients can examine the chart to see if several days of high or low glucose readings coincide with these particular factors. Then they can work with their doctor to make any necessary adjustments.
