Two Weeks of Continuous Glucose Data

My FreeStyle Libre adventure came to an end last Thursday. Fortunately, Abbott supplied me with two sensors (plus the reader) free of charge, meaning I have a second one sitting on my shelf at home. I’ve been watching some of the other bloggers in attendance at Diabetes Exchange who have already moved on to their second sensor without hesitation. However, I don’t feel quite ready to use mine just yet.

I should stress that this is not a bad reflection on the FreeStyle Libre itself. This could easily apply to any device that produces continuous glucose data. This is a very individual feeling after having access to this kind of data for the very first time in my life. Of course, your diabetes may vary. 

The FreeStyle Libre was one of the first major pieces of diabetes tech that I’ve used. Up until recently, I’ve only ever used finger sticks and insulin injections. I’ve never before had access to such detailed data, nor has it been so convenient and easy to obtain.

Traditional glucose monitoring has become second nature to me. I use a significant number of test strips throughout the day in order to evaluate my pre meal, post meal and overnight glucose levels. This doesn’t necessarily mean that I’m struggling with my diabetes. It’s just another tool that works really well for me in managing my diabetes throughout the day, and gives me significant peace of mind.

As you could imagine, I entered my FreeStyle Libre adventure with great enthusiasm. My reader was attached to me for the better part of two weeks. I carried it around with me in my track pant pockets at home. It lay with the remotes while I was sitting in front of the television, within easy reach. It sat in my shirt pocket at work. And I carried it in my jacket pockets when I went out.

The data was so convenient and easy to access. A simple scan, and I was able to see where my glucose levels were sitting. If I was curious again in 5 minutes time, I could easily do so again. I didn’t even have to contemplate getting up from the couch to do so. The appearance of trend arrows, and I could easily see what direction my glucose levels were headed, and if I needed to act on it.

In two short weeks, I formed quite an attachment to my Libre. For the better part, I relied on it as an indication of my glucose data. However towards the end of my 14 day adventure, scanning definitely became a bit of a compulsion. Data did start to feel like a weight on my shoulders.

My family suggested that perhaps I was only scanning so often because this was an exciting new product that I was trying to get the most out of. If I used it regularly, perhaps I wouldn’t. I was also starting out on insulin pump therapy at the time, and using the data to evaluate my insulin delivery settings on the pump.

Going back to finger sticks has felt quite freeing these past few days. I’m back to testing glucose levels at my set times – before meals, 2 hours after meals, 4 hours after meals, at bedtime and once during the night. I’m not tempted to over test, and I don’t feel so overwhelmed with data.

The Libre was a wonderful experience. I loved that it was so discreet, lightweight and convenient to use. This is actually something that I see myself using from time to time, unlike a CGM. Definitely for my next holiday. It was extremely insightful in fine tuning my insulin pump settings, and I’ll be putting my next sensor to good use in that department, too.

I just don’t feel that I’m the kind of person who could handle continuous glucose data all the time. Perhaps my opinion and needs will change with time and more experience in this arena. But for now, I feel I need to put some more distance behind me before I feel ready to insert my second sensor.


  1. I have only had experience with CGM but i also found the data a bit of an overload at times, even after weeks of continued use i was still micro managing my diabetes, with strong urges to check readings continuously. As you say and i agree, the data is invaluable when fine tuning your pump. Over time i found that once i had a longitudinal picture and i had my pump so finely tuned i infrequently needed correction does, i stopped using CGM continuously. I now only use CGM when i am unwell or intending to do extreme exercise regimes. Of course costs come into it as well, i guess if it was not so expensive i would use CGM all the time and believe that over time the urge to micro manage would subside. Overall this type of data enables ordinary persons to gain insights into their diabetes that otherwise would be impossible, when applied to diabetes it cannot be argued that better overall management is achieved both directly by the data obtained and indirectly by the secondary benefits.
