I wear a Dexcom CGM or continuous glucose monitor. I chose Dexcom because their accuracy is the best for me and the range/distance of the sensor transmission is the best available. I am asked this question quite often so I will list some pros and cons for me.
- I know what my blood sugar is or is near at all times of the day and night
- I can drive my vehicle without as much worry about going low suddenly
- I can sleep much better knowing that my Dexcom should catch my lows
- I can react to a high or low much sooner and take corrective actions
- I know what the food I eat does to my blood sugar and how quickly it affects me
- Dexcom makes me much more responsible for the blood sugar readings and helps me to say no to foods I know I just cannot conquer
- I can wear it for longer than 7 days and just keep restarting it
- It gives me much more confidence living with t1d because I can look at my Dexcom and see where my blood sugar is trending.
- The data can be shared with others and others can get alerts on their phones
- You can monitor your child's/spouse/significant others' blood sugar remotely
- You don't have to poke your finger a million times a day, only needs calibrating every 12 hours
- It helps you to nail down your insulin doses/pump settings better by watching your trends
- The receiver is rechargeable so I don't have to worry about having batteries for it all the time, I just need to make sure I have a micro usb cable handy
- Dexcom helps me when it comes to physical activity or being outside in the heat because sometimes I can drop so fast that I dont catch it until I am really really low. So my Dexcom alerts me and I can react sooner and I have confidence in knowing whatever I am doing that I can look at Dexcom and see if I am going low.
- You have another device attached to you all the time
- If you don't have the G5 you have to carry the receiver, which is what I do.
- Not paired to my first generation tslim pump
- I have to buy and use extra tape to get it to stay on, the built in tape is not sticky enough for me
- Costs can be high depending on your insurance coverage
- Some micro usb cables are not recognized and/or you have to plug and unplug it a bunch of times to start charging
- Sometimes when the G4 transmitter battery is going low it will give a warning that it is going low but sometimes it doesn't. I have had this happen to me.
- The sensor you wear on your body is rather large and when you have to use tape it takes up quite a large spot on your body.
