Key Components of CGM Systems
Continuous glucose monitoring (CGM) systems have transformed how people with diabetes handle their blood sugar. These tools offer up-to-the-minute glucose data. This lets users tweak their diet, exercise, and meds based on this data. The many parts of CGM systems team up to give precise, dependable glucose readings.
The core element of a CGM system is the sensor. It’s a tiny, pliable wire placed just under the skin. This sensor constantly checks glucose in the interstitial fluid around cells. This gives a full view of how glucose changes over the day and night. Depending on the type, sensors can work for seven to 15 days, and some last even longer. There’s also a wait time of 30 minutes to two hours before the sensor starts showing glucose data.
The sensor links to a small device called a transmitter, which you wear on the outside of your skin. This transmitter beams the glucose readings to a receiver or app on your phone. Users can then see their glucose levels live. They also notice any trends or patterns. CGMs have been found to lead to fewer times of low blood sugar and a drop in A1C levels for those with Type 1 or Type 2 diabetes. They’ve cut down on the number of blood sugar checks needed each day, too.
CGM systems contribute to better glycemic control by providing continuous data that helps users make informed decisions. Then, there’s the receiver or phone app, which is the last piece of a CGM system. This device shows you your glucose levels as they really are, plus graphs and alerts. With many CGM models, you can set up your own alarms. They warn you when your glucose is above or below a safe level. Some CGM systems even link up with insulin pumps. This makes managing diabetes smoother and more automatic.

Introduction to Continuous Glucose Monitoring (CGM)
Continuous Glucose Monitoring, or CGM, has changed the game in managing diabetes. It provides real-time glucose data day and night. More and more people are using this tech because of its clear benefits. It gives a detailed look at glucose trends, improving how diabetes is treated and controlled. CGM systems contribute to better glycemic control by providing continuous insights that help in making informed decisions about diet and insulin usage.
What is CGM?
A continuous glucose monitor is a device you wear. It measures glucose in the interstitial fluid under your skin. It shows glucose levels every minute, which is about 1,440 readings a day. This lets you see your glucose patterns over time, not just right now. CGM includes a sensor under the skin, a transmitter, and a receiver or app for your phone to see your glucose info.
Benefits of CGM for diabetes management
Using a CGM can make managing diabetes better and cut down on low sugar events. It leads to improved outcomes. With real-time glucose data, you can smartly manage your diabetes. This includes changing your insulin, food, or how much you exercise. It also helps keep your glucose levels in range for type 1 diabetes.
One big plus of CGM is you might not need as many finger pricks to test your glucose. This means less pain and more convenience for those with diabetes. CGMs can also warn you if your glucose levels get too low or too high to help avoid serious situations.
Welcome surprises, CGM can work with shots or insulin pumps, too. It can even link to pumps to give you insulin automatically. You can also share your glucose data with friends, family, or your healthcare team in real-time or later, which is a helpful feature.
CGM technology has made a huge difference for people with diabetes. It brings a new level of personal and detailed glucose monitoring and care.
But even with all these benefits, not everyone hits their glucose goals. Things like what you eat, how you exercise, stress, meds, and sleep can change your glucose. So, if your levels are off, talking with your doctor is key to find out why and how to fix it.
Sensors: The Heart of CGM Systems
The sensor is like the heart of a Continuous Glucose Monitoring (CGM) system. It’s a small but vital part that checks glucose levels in the fluid around cells. These sensors are key in managing diabetes. They give real-time data on glucose, helping people make smart choices about their health. Over time, these sensors have improved a lot. Now, they can check glucose levels every 30 seconds and show levels every 5 minutes. Sensors contribute to better glycemic control by providing continuous and accurate glucose readings.
How CGM sensors work
CGM sensors are placed right below the skin to measure glucose in the interstitial fluid. They use an enzyme and an electrode to detect glucose. This creates an electric signal that shows how much glucose is there. Then, the sensor sends this information to a device. This device could be a small machine or an app on a smartphone. It lets the user see and understand their glucose data.
One big plus of CGM sensors is they give data all the time. This helps people see trends in their glucose. It’s very useful for those with diabetes. They can use this info to adjust their medicine, eating, and exercise to stay healthy. For example, using sensors with a pump can lower a key diabetes indicator called HbA1C by 0.7% compared to other methods.
Sensor placement and wear time
You usually wear CGM sensors on the belly or arm to measure glucose in the interstitial fluid. They’re kept in place by special tapes. Different CGM systems might need the sensor in different spots. For instance, the Eversense CGM system goes under the skin on the upper arm.
It’s the first to be put in by a doctor and can work for 90 days.
How long a sensor can be worn has got better, too. In the past, they had to be changed every 3-5 days. But now, they can last 7 to 15 days before needing to be replaced, depending on the brand. This means fewer times you have to put in a new sensor and better glucose tracking.

Transmitters: Connecting Sensors to Displays
In a CGM system, the transmitter is key. It sends glucose data from the sensor to the display wirelessly. This lets users see their blood sugar levels in real time through a smartphone app or receiver.
The transmitter can be reused or thrown away, depending on the CGM model. Transmitters contribute to better glycemic control by providing continuous and accurate glucose monitoring.
Some transmitters can be reused with each new sensor. Others are one with the sensor, so you replace them together. Still, some CGM systems need time, up to two hours, to start working after you put them on. The transmitter might also need to be charged before use for uninterrupted data sharing, a must for sensors that last 7 to 14 days.
To keep the sensor and transmitter safely stuck to the skin, people often add more adhesive. This helps avoid the transmitter falling off during the day and provides steady data. But remember, most CGM systems show a delay of 10-12 minutes in glucose readings, which is vital when reading these numbers.
“The CGM transmitter is the unsung hero of the system, working tirelessly to keep us connected to our glucose data 24/7.”
The prices of CGM transmitters can change depending on the brand and type. For a Dexcom G6 in 2022, it cost around $422. Sensors, which you need to replace every 10 days, add to the cost.
