As stated above, a CGM is not a meter and finger pricks are still required when on a CGM. I just retired my CGM bit had used one for 4 years. Here are my answers
:- How do I know when would be best to calibrate my sensor to not botch all my future readings? If you go to a CGM, there are a ton of rules, equations, etc. you will need to learn. For example, never calibrate below 70 or above 170. There are many more.
- How do I accurately calibrate it, because the blood reading you would take to calibrate is ahead of the CGM reading from interstitial fluid, right? That is one of the reasons that readings are often inaccurate on a CGM.
- Also is it painful to have a meter lodged on the abdomen? Wearing it is not uncomfortable; it has a flexible catheder like the pump. However, I always hated inserting it, As Acid Rock once said,, the needle looks a little like a 10 penny nail.. I have ti get my nerve up to insert it. Additionally, it is covered over to keep the sensor from flopping around, and I have had mine bleed two or three days after insert, which was not fun.
- Did anyone have any experience with better A1C using one method over the other? A lot of people seems to get better results on A1Cs. In my case, my blood glucose levels were so tightly controlled (A1C of 5.1) that I was using it to protect myself from overnight lows. I helped me see patterns and trends and was helpful adjusting basal settings.
- I also heard that how your CGM readings correspond to your blood readings depends on where the CGM is placed, has anyone observed this? Yes. Just like a pump, there are good spots and not so good spots.
- Considering these problems, for those who have had experience with both the fingerprick method and CGM, do you find the CGM to be easier to use? As we know that both methods must be used with a CGM, here is why I stopped using mine. I became obsessive about looking at my meter, making adjustments if I was running high or low, etc. I worried all the time. There were nights when it beeped so much that we could not sleep, even when I was not really low. This lack of sleep was affecting our health. And I hated the procedure for insertion. Unlike a pump, this can be a three hour process, if all goes well. It can be a great tool, but I am happier without it.
- Which is your ideal meter, any meter, CGM or not CMG, and why? I use the military pharmacy system, and they carry accucheck products, so I have always used accucheck.
- Or just for fun, any ideal dream/fantasy meter? One that was more accurate, as even a meter can standardly be off 40 points. One that could accurately read glucose levels without blood, say with saliva....
Good luck--I hope this helps.
