Switching from a pump to multiple daily injections (MDI) isn’t nearly as common as people who switch from shots to a pump. But people do it. And I’m one of them. It’s not that I don’t like insulin pumps or that they don’t work. It’s just that when my pump happened to break back in March, I decided to take advantage of the opportunity to have a “pump vacation.”
I’ve discovered that one of the most difficult parts of being off the pump is doing the D-math that my pump used to do for me.
When I first started my break, I used my iPhone’s calculator to do all my calculations. First, I’d enter my blood sugar and figure the correction factor. Then, I would enter my carbs and use my I:C ratio to figure the bolus dose needed. I’d then add them together, do some rounding, and inject. It worked really well for several weeks.
And then I got lazy.
Instead of taking out my calculator, I just started estimating how many units of insulin I needed, and let me tell you, my mental math skills have never been that good. I also could never accommodate for Insulin On Board (IOB) properly, which was frustrating.
Thanks to our columnist, Wil Dubois, another pump renegade, I discovered RapidCalc, a new mobile app designed to work like a Bolus Wizard calculator. A couple of weeks later, I found out about a similar tool, ManageBGL, when the company followed me on Twitter. Apps to replicate a Bolus Wizard? Genius!
