Final answer:
Continuous Glucose Monitoring (CGM) is the method of continuously tracking glucose levels via a sensor inserted under the skin, offering real-time glucose readings and aiding diabetes management.
Step-by-step explanation:
Continuous Glucose Monitoring (CGM)
The method of tracking glucose levels 24 hours a day through a tiny sensor inserted under the skin on the abdomen or arm is known as Continuous Glucose Monitoring (CGM). These devices provide real-time glucose readings, alerting users to highs and lows that may occur throughout the day and night. CGM systems typically involve a small, disposable sensor inserted under the skin, which measures the level of glucose in the interstitial fluid. A transmitter attached to the sensor sends the data wirelessly to a display device, such as a handheld monitor or a smartphone app, allowing for close monitoring of glucose levels without frequent fingersticks.
CGM devices are particularly useful for patients with diabetes, as they help in maintaining a more precise control over blood glucose levels, which can be critical in managing the condition. This is a step forward from traditional methods, such as the use of test strips and reflectance photometers that required a drop of blood from a finger p_rick. The information from CGM can also guide treatment decisions and, in some cases, the devices can be linked to insulin pumps to automatically adjust insulin delivery based on the glucose readings.
For patients with hormone resistance, such as those with Type 2 diabetes, where body cells do not respond to normal amounts of insulin, CGM can be an integral part of managing their condition. By providing detailed glucose trends, CGM can help in determining the most effective treatment plans, potentially including medication adjustments, dietary changes, and physical activity considerations.
