Which of the following best describes the term "glycemic control"?

Glycemic control refers specifically to the management of blood glucose levels within a target range to minimize the risk of complications associated with diabetes. This involves monitoring and treating blood glucose levels to ensure they remain stable and as close to normal as possible. Effective glycemic control helps to reduce the risk of diabetes-related complications, including cardiovascular disease, neuropathy, and retinopathy.

Maintaining blood glucose within a defined range involves a combination of lifestyle modifications, medication adherence, dietary changes, and regular physical activity. Therefore, option B accurately encompasses the essence of glycemic control, which is fundamentally about blood glucose management rather than other aspects of metabolism, caloric intake, or the frequency of testing alone.
