Dexcom G7
The Dexcom G7 continuous glucose monitoring (CGM) system is revolutionizing how individuals manage their diabetes. This real-time glucose monitoring without the need for finger pricks, CGM gives users insight into their glucose levels, allowing them to make informed decisions. I love using this data to help clients learn more about patterns when it comes to blood sugars and outside influences.
Everything you Need to Know about Dexcom G7
Let’s learn more about the Dexcom G7 system, exploring its technology, components, and functionalities.
So, here’s the deal with this cool tech: the sensor, using continuous glucose monitoring (CGM), checks out your glucose levels in the fluid just under your skin. This is the interstitial fluid which is slightly different from the capillary blood measured with a finger prick.
And guess what? You can say goodbye to those annoying finger pricks because this method is totally non-invasive. It’s like a hassle-free pass to keeping tabs on your glucose levels, making life a whole lot easier for you.
It’s important to note that interstitial fluid has a lag time vs finger prick capillary blood directly from the blood vessel. See the illustration for a visual guide but essentially glucose is in the blood vessel prior to traveling into the interstitial fluid- creating a 10-15 minute lag time in readings.
The glucose measured in two different areas can vary up to 20%, as numbers increase the variation gets bigger. This can be especially noticeable when glucose levels are changing rapidly, such as right after a meal. The blood sugar from a fingerprick will increase before a CGM reading. The trend arrows will illustrate how quickly levels are changing and improve understanding in how different things can affect blood sugars.
Dexcom Sensor and Receiver
The beauty of the G7 (vs the G6) is that it has a sensor and transmitter all in one piece. The G6 has a transmitter as a separate piece that must be replaced every 3 months. By having this combo it not only makes the device more affordable but it is also much easier to use.
The sensor is a small, discreet device that is inserted just beneath the skin and worn on the body to monitor glucose levels continuously. This is replaced every 10 days. The transmitter (now included as part of the sensor) is responsible for transmitting glucose data from the sensor to the receiver or mobile app.
A receive or mobile app can be used to receive the data and evaluate glucose readings. The G7 is also significantly smaller, make it more enjoyable to wear and conceal. The G6 is also currently being phased out so I’d go for the update on your next refill.
Dexcom G7 app and Dexcom Clarity
The Dexcom G7 app includes not only real time readings every 5 minutes but customizable features such as low blood sugar alerts, rising blood sugar alerts and more. These settings can be tuned to whatever limits you desire. The Clarity app takes all the glucose data from your Dexcom G7 continuous glucose monitoring system and turns it into easy-to-understand charts and graphs.
So, instead of staring at a bunch of numbers, you get these cool visuals that show you how your glucose levels have been doing over time. It’s like having a personal glucose coach right in your pocket, helping you keep track of your numbers and stay on top of your diabetes game.
Plus, you can share these reports with your healthcare team, so they can see how you’re doing and give you the best support possible. It’s all about making managing your diabetes a little less complicated and a lot more manageable. Check out my report below. GMI= estimated A1c Time in Range was 97%. Let me know if you have any questions in interpreting the report.
Dexcom Overlay Patches
The Dexcom G7 also includes overlay patches. Overpatches provide an extra layer of protection and security. These clear, waterproof patches are perfect for ensuring your sensor stays securely attached and clean, even during activities like swimming or bathing.
My Experience wearing Dexcom G7
I wore a Dexcom G7 (provided by my local representative to experience the technology firsthand). While I do not have diabetes I do have a strong family history of diabetes and have a personal history of hypoglycemia. I especially noticed nighttime low blood sugars after a glass (or two) of wine. The alert for dropping under 55 went off and woke me up. I definitely felt crappy but did not need to treat because my lived kicked on and released sugar to bring me back up to normal.
The highest reading I had I believe was around 200 and that was after eating a large portion of pasta. Again, not having diabetes my pancreas released insulin and was able to bring my blood sugar back down quickly to normal range. Some of my other higher readings were during exercise. This makes sense because it is a stress on your body- but it does help lower them quickly overall creating a good time in range.
It was an interesting experience but not a necessary one for someone who does not have blood sugar issues. My biggest takeaway is how important it is to pair alcohol with food- even if you don’t have diabetes!
Dexcom G7 Review
In conclusion, the Dexcom G7 continuous glucose monitoring system represents a significant advancement in diabetes management technology. With its innovative sensor technology, reliable data transmission, and user-friendly components, it empowers individuals with diabetes to take control of their health and live life to the fullest.
