Trusting our Meter Results
In this day and age, people with diabetes rely on technology to help us make informed management decisions. Pumps, with their insulin-on-board and bolus wizard functions help with insulin dosing decisions. Continuous glucose monitors provide important blood sugar trending information that allows for better insulin dosing and lifestyle decisions. Then, there’s the basic glucose monitor which is still the foundation of a PWD’s technological arsenal.
That’s why it is extremely frustrating when the basic glucose monitor is unreliable. Last Thursday, before heading out for a morning run, I tested my blood sugar and got a result of 192 mg/dl. I’d just tested less than 30 minutes before (after treating a low that morning) and was 113 mg/dl. So, I doubted that 192 mg/dl was accurate and tested again; this time is was 140 mg/dl. Okay, that seemed more reasonable but I didn’t like that 50 plus point swing and thought one more test would help me narrow in on my actual blood sugar. The third test returned a result of 240 mg/dl!!! Instead of clarity, I was now more confused and frustrated than before. In a bit of a rage, I tested again and saw 203 mg/dl.
Since I’d been low (after waking with high blood sugar and overcorrecting), I figured that there was enough insulin on board and since I didn’t have my Dexcom on, I didn’t want to worry about dropping too low on the run. I opted not to bolus and hoped my blood sugar would gently trend down while running. Luckily, that’s what happened and my blood sugar (if my meter can be trusted!) was 150 mg/dl after exercising.
