High blood glucose levels can be controlled with diet, exercise, and medications. In many cases, doctors suggest that people use blood glucose meters or monitors. These devices provide patients with immediate feedback on how well their lifestyle changes and medications are working. Your doctor will tell you what time of day and how often to check your blood sugar levels, and may also measure your A1C levels every few months in order to understand trends in your blood sugar levels over extended periods of time.
