How is a Continuous Glucose Monitor (CGM) device inserted?

Time to read 5 min

When it comes to a continuous glucose monitor or CGM, you need a specialist to insert the device. A tiny surgical incision is performed in the skin, around the upper arm region, and the sensor is placed inside it. A transmitter is worn on the other side that relays that data to a receiver, generally a smartphone. You can get accurate and real-time glucose levels data through the CGM ecosystem.

Exploring the major benefits of using a CGM

There are several inherent benefits of using the right CGM device. You can get better quality blood glucose levels when using a CGM compared to finger pricking and other methods. It is also a more convenient option, which is why many people managing diabetes prefer tracking their levels with a CGM device.

Ease of daily tracking

One of the most important reasons why people use CGM devices is the ease at which you can track your levels daily. You don't need to use any other device or system to measure multiple recordings each day, when you have a CGM embedded.

Simple to install

The ease of installation at the arm is one of the main reasons why people use CGM devices. You can get your glucose levels checked daily, multiple times a day, without worrying about uncomfortable pricking or other forms of blood drawing.

Consistent tracking of levels

With a CGM device, you can get more consistent tracking of levels throughout the day. You can get your glucose levels checked before and after meals, to optimize your diet. You can also check your levels during exercises so that you can sustain your glucose levels through intense workouts.

How does a continuous glucose monitor work?

If you are planning on using a continuous glucose monitor, then understanding how it works can help you manage it better. The following steps are involved in the installation and working of a CGM device.

1) A tiny sensor is inserted in the skin, generally in the upper arm region, which will start to record the sugar level readings.

2) The sensor is designed to read the interstitial glucose level for a fixed number of days (usually 14 days)

3) Through a built-in transmitter the data is sent to a reading device, which displays your sugar level readings in regular intervals.

4) Some products are designed to transmit data to a dedicated device, while others can send data to your smartphone directly. 

Why use a continuous glucose monitor CGM device?

There are many benefits to using a continuous glucose monitor device, which is why it is rising in popularity. You need the right CGM device that is developed by a trusted manufacturer so that you can accurately measure your blood sugar levels over time.

Perfect alternative to finger pricks

Older people and individuals that are sensitive to pricks can use a CGM as an ideal alternative. It allows people to access critical health information without undergoing invasive pricks daily. You can also improve your adherence to tracking protocols when you have an automated sensor capturing device installed. 

 Adapts to individual's lifestyle

A key reason why people use a CGM device is the adapting to their lifestyle. You can go swimming, exercise, go for long walks, and enjoy a party, while having complete control over your glucose levels in real-time.

Accurate glucose readings

A major benefit of opting for a CGM is the accuracy with which your glucose readings can be measured. You can get the right sugar levels data from within the sensor-reader ecosystem, as it is installed directly in your skin.

Ease of convenience

A CGM is one of the most convenient ways of gaining sugar level data, making it an ideal way to track health markers. You can also share a screenshot or report of your data with your healthcare provider for any oversight or recommendations.

Continuous tracking of levels

There are minimal restrictions about how many readings can be captured using the CGM device. You can gather information about your blood glucose levels with ease at any time. There is a continuous monitoring provided to you when you opt for a quality CGM device.

Recording glucose data in sleep

A CGM is the only device that records your blood sugar levels during your sleep. Since the tracker is inserted within the body, there is no need for finger pricks and no requirement of sleep data analysis.

The sensor automatically tracks data during your sleep, to provide doctors with blood sugar data when you sleep. Any significant spikes or dips can be tracked in real-time, making it highly important to use a CGM for tracking. 

Important requirements for using a CGM

When using a CGM device, you need to be mindful of a few points. You need to check the continuous glucose monitoring CGM device twice a day to ensure that it is functioning effectively.

Testing your CGM device

You can test a few drops of blood on a glucose meter and test your blood sugar levels through the device at the same time. The result should be identical, indicating that the device is measuring your glucose levels accurately throughout the day.

Replacing the sensor regularly

As a part of your regular upkeep, you need to also replace the CGM sensor every week or fortnight, based on what the manufacturer recommends. This will help you get accurate measures of your blood glucose levels so that you can manage your sugar correctly.

Be mindful of notifications

What is important to remember is to act immediately when your CGM starts to make sounds or notifies you of anomalies. It is important to take immediate action to control sugar levels for people with diabetes so that you can use an insulin pump when needed.

Regularly tracking your sugar levels

It's important to consistently track your sugar levels through the continuous glucose monitoring device. You should be able to track various levels within the reading, ensuring that the sensor is working correctly. 

Understanding the importance of tracking sugar levels

If you have diabetes and are looking to manage the disease long-term then you need the right sugar tracking device. You need to track your levels consistently to ensure that you can detect any spikes quickly. You can also get a better sense of why your levels are fluctuating over time, if there are no changes in your diet or lifestyle.

Gaining better glucose insights

Tracking sugar levels closely can help in bringing visibility into insulin requirements. Tracking the highs and lows of sugar levels consistently can provide better insights to doctors who can monitor people with diabetes closely.

Managing Hyperglycaemia & Hypoglycaemia better

Another important reason why tracking sugar levels consistently is key is to manage high and low blood sugar issues closely. Both hyperglycaemia and hypoglycaemia can be tracked better with the right management strategies.

Preventing life threatening situations

A major benefit of closely tracking sugar levels is the prevention of life-threatening situations. The risk of having a life threatening episode declines significantly when you are able to measure your blood sugar levels throughout the day.

More control over unpredictability

Tracking sugar levels consistently can help provide greater control through periods of unpredictability. If you find that your energy levels fluctuate significantly throughout the day, then there may be an issue with your sugar levels management.
