Continuous Glucose Monitors (CGMs) are small devices used to monitor glucose levels in the body continuously throughout the day and night. They are commonly used by individuals with diabetes to manage their blood sugar levels, but they can also be used by people without diabetes who want to gain insight into their health and wellness- like me. CGMs consist of three main components: a small sensor, a transmitter, and a receiver or smartphone app. The sensor is usually inserted just beneath the skin, often on the abdomen or the back of the upper arm. It measures the glucose levels in the interstitial fluid, which is the fluid that surrounds the body's cells. The sensor is connected to a transmitter, which wirelessly sends the glucose data to a receiver or a smartphone app. The receiver displays real-time glucose readings, trends, and alerts. Some CGMs also offer the option to share the data with healthcare providers or caregivers, allowing for remote monitoring and support. By using a CGM, individuals can gain a better understanding of their glucose patterns and how their bodies respond to different factors, such as food, exercise, stress, and medication. CGMs provide valuable information about glucose fluctuations throughout the day, including spikes and dips that may go unnoticed with traditional fingerstick glucose meters. Here are five ways CGMs can help you understand your health: 1. Immediate feedback: CGMs provide real-time glucose readings, allowing you to see how your blood sugar levels change in response to various activities or events. This information can help you make immediate adjustments to your diet, exercise, or medication to maintain stable glucose levels.
2. Trends and patterns: CGMs track your glucose levels continuously, offering insights into long-term trends and patterns. You can identify how your glucose levels vary at different times of the day, identify high or low points, and observe how specific actions or lifestyle choices impact your glucose control.
3. Hypoglycemia and hyperglycemia detection: CGMs can alert you when your glucose levels are too low (hypoglycemia) or too high (hyperglycemia). These alerts can help you take prompt action to prevent severe complications or manage your glucose levels effectively.
4. Meal and exercise analysis: CGMs can help you understand how specific foods, meals, or exercise routines affect your blood sugar levels. You can make informed decisions about your diet and exercise choices based on real-time data and adjust your habits to achieve optimal glucose control.
5. Sleep monitoring: CGMs can provide insights into your glucose levels during sleep, helping you identify nighttime patterns and make adjustments to improve overnight glucose control. This is particularly useful for people with diabetes who experience dawn phenomenon or nocturnal hypoglycemia.
I recently went to the local pharmacy and purchased the FreeStyle Libre2. It is pretty easy to put on, and all you need to do is download the app and the monitor starts working in an hour (and lasts for 14 days). I am currently on day 4 of tracking and am obsessed with taking my glucose levels at all times of the day! Being the data nerd that I am, I am really excited to learn about how my body handles certain foods/drinks and exercise. I am working with a dietician currently as well, so along with her expertise can gain some insights into my glucose levels and how best to support it. It is important to note that while CGMs provide valuable information, they are not a substitute for regular blood glucose testing or medical advice. Consulting with a healthcare professional is crucial for interpreting the data and making informed decisions about your health management.
