Yesterday I got to the office, opened my kit to test my blood before eating breakfast at my desk, and discovered that I only had two test strips with me. Ugh. I had two options: run home to get more strips or ration the two strips by testing at strategic moments during the day. I opted for that later and planned to test before lunch and again in the late afternoon.
Had I been wearing my Dexcom, this wouldn’t have been a big deal at all. However, I’d just removed a sensor a few days before and was taking a little break with the plan to put on a new sensor after swimming again the following morning.
I’d been at 70 mg/dl after swimming and had just an apple sauce pouch to correct about 90 minutes before. I figured I was in range and calculated a breakfast bolus for my Almond Butter bar and coffee. Seeing as I wouldn’t want to do a postprandial check, I gave more thoughtful consideration to the bolus amount.
A little over an hour after eating, I felt like my blood sugar was dropping. I decided to test and confirmed a blood sugar of 71 mg/dl. Ate a few grapes and a small banana from my office fruit bowl and assumed I’d bring my blood sugar up to the higher end of “in range”.
Luckily I had a very low carb lunch with me. So, I bolused 1 unit of insulin and ate my two egg muffins with avocado, without much concern about my blood sugar.
Finally, at 4:00 p.m., I used the last strip and was pleased to see a result of 107 mg/dl.
Upon reflection on my day, it occurred to me that there’s no substitute for knowing your body and making sound food and insulin bolus decisions. Although I love having blood sugar data available to me (in either finger stick or CGMS form), I can manage my blood sugar over short periods without a lot of data, if I’m willing to think about my actions carefully. Also, I’m sometimes guilty of letting blood sugar information cause unwise therapeutic decisions (for example when I give a correction bolus too soon)!
So, while I won’t restrict my testing on a regular basis, this was a good reminder to me that wise food choices, accurate insulin dosing, and bolusing ahead of meals are the bedrocks of my diabetes control.
