CGM: how did we get along without it?

It’s been a while since my last post. We’ve been busy. V started wearing Dexcom Continuous Blood Glucose Monitor (CGM) a few weeks ago. We had a bumpy start. Something stopped working almost a week after we put on the first sensor. We replaced a couple of sensors but it was not fixing the problem. After talking to tech support, we replaced the receiver. That did not fix the problem either. We then got the transmitter replaced and now everything seems to be back on track. And let me tell you, it is awesome.

V was a little nervous at first about putting the first sensor on. We all were. But it turned out to be a fairly easy process. And after an initial pinch, we were all relieved that it did not hurt. In fact, after a little while V completely forgot it was even there. It did not seem to bother her during any activities, including bathing, sleeping and sports. And it gave us data. Lots and lots and lots of data. Now we are seeing all the in-betweens. We are learning that V’s BG really shoots up after she eats and it takes a good 3 hrs to bring it back to the normal range. We are also learning that she stays stable at night. That is a tremendous relief! Of course everything can change in the future but for now we are thrilled that there really is no reason for us to check her in the middle of a night on regular basis. We are also learning how exercise affects her BG levels hours after it’s over. And it’s allowing us to fine-tune her carb snacks during and after so that we can avoid huge swings and drops. We are not quite there yet, it’s a work in progress, but it’s so cool to have this information to guide us.

We are also excited about how accurate the CGM is most of the time. Once in a while there will be a fluke. Like when a couple of mornings ago Dexcom gave us a low alarm whereas blood check showed a perfectly good number around 100. But those moments are rare and often CGM is within 10 points of the blood check. CGM does not replace finger pricking. We sill do it at meals and whenever we make a decision about either treating a low or correcting a high. But it’s definitely reduced the need to poke a finger at night, or during exercise or other activities, because then we can rely on CGM to give us a good ballpark number of where V is at.

We have not yet had a 100% match to the blood check. But I’m sure one day it will happen. For today, I will take this (113 vs. 114) as pretty darn awesome:
