What type of monitor is used to track real-time glucose levels in patients with diabetes?

A continuous glucose monitor (CGM) is specifically designed to track real-time glucose levels in patients with diabetes. This device measures glucose levels in the interstitial fluid just beneath the skin, providing continuous readings throughout the day and night. Unlike traditional glucose meters, which require periodic fingerstick blood tests, CGMs offer the advantage of real-time monitoring, notifications for high or low blood sugar levels, and trend data that can help patients and providers make informed decisions about insulin dosing and dietary changes.

By using a CGM, patients can gain valuable insights into how their glucose levels fluctuate over time in response to food intake, physical activity, and other factors. This continuous tracking can significantly improve diabetes management and help prevent complications associated with uncontrolled glucose levels.

The other options, such as a blood pressure monitor, thermometer, and pulse oximeter, serve different critical health monitoring purposes but are not designed for glucose level tracking. For example, blood pressure monitors measure cardiovascular status, thermometers assess body temperature, and pulse oximeters check oxygen saturation in the blood. Each of these devices plays an essential role in patient care, but none can provide the real-time glucose monitoring that a continuous glucose monitor can.
