Hi, I'm new to the site and am most interested in hearing from people who have tried continuous glucose sensors with their pumps, especially the Medtronic brand. I just got my first kit and sensors and the very first one I used was not a good experience. I believe I understand all the basics and know when to calibrate and how to check things, etc. However, my readings were often 50% or more off from my glucose meter, both higher and lower.

In addition to this, I received several low blood sugar warnings during the first night but never felt any of them and, because of the disparity from my monitor in readings, I don't even know if they were accurate. I have the warning set to vibrate because I'm somewhat hard of hearing but evidently the vibrate warning (although it works great during the day) just won't get the job done when I'm asleep.

I'm going to try my second sensor in a few days. Any advice? Thanks.

I put one in before I go to bed and let it "soak" all night and then when i wake up I will start the new sensor, the more fluid on it the better off you are.

Hello Barbara,
I highly recommend you join this group:
where you can read perspectives about all brands of CGM devices.

I can only offer my opinion on the Dexcom 7+: I love it. The values shown get closer to the values from your meter as the sensor has been in place more days. The ability to wake up before you go dangerously low is great. Overall, the only downside I see to CGM technology as a whole (as with every diabetes therapy, really) is cost. Depending on your insurance, assuming your ins. company approves you (if you have trouble getting approved, I recommend checking http://cgm-antidenial.ning.com/), it can get expensive. For instance, before hitting my deductible, I pay $250 for four sensors, which "technically" are meant to last a week (but if you read the CGM Users group, you will quickly learn that you can extend them longer than 7 days).

Here is an article on the experience so far I recently wrote on dLife:

Hope this all helps!
