A Continuous Glucose Monitor (CGM) is a small device that tracks blood sugar levels in real-time. It consists of a tiny sensor placed under the skin, which measures glucose levels in the interstitial fluid. The data is sent to a display device, usually a smartphone or a dedicated receiver, allowing users to see their glucose trends throughout the day. This technology helps people manage diabetes more effectively by providing continuous feedback on their glucose levels.
CGMs are important for health because they help individuals with diabetes understand how their bodies react to food, exercise, and medications. This real-time monitoring can lead to better decision-making about diet and insulin use. By catching highs and lows in glucose levels quickly, users can take action to maintain stable blood sugar, which is crucial for preventing complications related to diabetes.
The basic function of a CGM in the body is to provide a constant reading of glucose levels, helping users maintain their target ranges. Unlike traditional blood glucose meters, which require finger pricks to test blood samples, CGMs offer a painless and continuous way to monitor glucose. This ongoing data collection can reveal patterns and trends, making it easier for users to adjust their diabetes management strategies.
Overall, CGMs represent a significant advancement in diabetes care technology. They empower users with valuable information about their glucose levels, enabling them to lead healthier lives with more informed choices.
