@celia16 I have a Dexcom G6 continual glucose monitor (CGM) as of February 2022. I have experienced some inaccuracies with that, particularly in the 24 - 72 hours after a sensor change. For example a greater than 100 point difference between CGM reading and glucometer reading. I know all about that CGM tests interstitial fluid and glucometer tests blood sugar. But still it was frustrating (especially in regards to low alerts) when CGM warned me that I was less than 40 and glucometer showed 139! Before checking the glucometer I panicked, overtreated and spiked to 300+. Lesson learned. In the 24 - 72 hours after a sensor change I check the glucometer often.

For the insulin pump I use Omnipod 5 since February 2023. This was recommended for me by one of the Mayo Clinic (Rochester, MN) endocrinologists. My local endocrinologist was leaning towards a Tandem pump. Because of a Medicare eligibility requirement I found out that I was not eligible for coverage for the Tandem but I was for the Omnipod 5 under part D. So we went with Omnipod 5.
There turned out to be 2 benefits to that. At the time it was the only one that was tubeless (a small benefit). The more important benefit is that it communicates with Dexcom G6 in a closed loop to recommend mealtime and correction boluses using an algorithm based on calculated “insulin on board”. This has started to be way over my head mathematically speaking but I can’t argue with the results. My A1C is “good” according to my providers and the CGM graph is increasingly approaching a greater percentage of steady flat line time in range. Before it looked like a mountain range with terrible peaks and valleys.

Another thing I might add is that I had a Medtronic insulin pump prior to 2000. It helped me achieve an A1C less than double digits but it was “ver primitive” according to my husband. I felt it was not user friendly at all. That was a long time ago. I hope your experience with Medtronics pump is better.

Could you keep me posted on how it’s going?
