Correction Bolus Ban
As I predicted several months ago when I began using the Dexcom CGMS again, my biggest frustration is when I overreact to the information and make poor decisions in my blood sugar management. Typically this takes the form of giving correction boluses when I see arrows pointing upwards after eating.
I’ll have just giving a meal bolus, usually within the last hour, but those arrows strike an emotional chord with me. It’s like I assume that the arrow is going to continue to climb unless I do something about it. When, in reality, if I just wait (experience has proved this is the case), the arrow will level out and often even drop, from the active meal bolus insulin.
So, as part of my New Year’s Resolution – I made a very specific declaration: no correction boluses until 2 to 3 hours after a meal bolus. In short, I’m referring to this as my “correction bolus ban”. This reminder will hopefully keep me from reacting to the Dexcom information too hastily and let the insulin that’s already in my body plus the passing of time help bring my blood sugar back into range.
However, I need to find a way to track when I gave a meal bolus (here’s one place I really miss a pump!). I’m thinking of using my phone reminder to note the time of my meal injection so I can easily track the 2 hour postprandial time. Along those lines, I’m thinking of different criteria I can use to gauge whether I really need a correction bolus. Such as: only if I’m over 180 mg/dl and the arrow still points up. Otherwise, I’ll wait another hour to see what the Dexcom graph is showing. Basically, I want to avoid having to snack between meals in order to keep my blood sugar from bottoming out.
I’ll let you know how this new system works!
