What is the role of continuous glucose monitoring in insulin therapy?

Continuous glucose monitoring (CGM) plays a crucial role in managing insulin therapy for individuals with diabetes by providing real-time blood glucose levels. This technology allows patients and healthcare providers to track glucose trends continuously throughout the day and night, enabling timely adjustments to insulin dosing and lifestyle choices.

By delivering frequent and accurate readings, CGM helps in making informed decisions regarding insulin administration and dietary intake, effectively reducing the risk of hypo- or hyperglycemic episodes. With the capability to alert users to rising or falling glucose levels, CGM empowers patients to manage their diabetes proactively, promoting better overall glycemic control.

While other options suggest functionalities of insulin management, they do not accurately describe the primary purpose of continuous glucose monitoring. For instance, CGM does not directly provide scheduled insulin doses, monitor dietary habits, or replace the need for injections; instead, it serves as an important tool to enhance the effectiveness and safety of insulin therapy.
