The vibrating wakes me up for the third time this night. It’s 3 a.m., and my new continuous glucose monitoring system (CGM) says my blood sugar reads 55. I know it’s a lie. I recently checked my blood sugar, and it was stable at 93. I have no active insulin in my system, but I just started this CGM, which I have decided to call “Cosmo,” and the nurse said it may take a few days to reflect my actual blood sugar. It’s a shame, but in the few weeks that I’ve had Cosmo, I still won’t give it up.
In the almost five years that I’ve had Type 1 diabetes, I’ve thought about investing in a CGM, which uses a sensor to monitor my blood sugar 24/7, but there can be a 20-minute delay since it’s reading my glucose levels from the interstitial fluid (a thin layer of fluid that surrounds the body’s cells), as opposed to a glucometer that reads it from a blood sample. I’ve always erred on the hypoglycemic side – two seizures in my short history as a result.
But in addition to the added expense of a CGM (my health insurance history has not been very consistent), I didn’t know if I wanted a 24/7 reminder of my diabetes. I wasn’t sure I really wanted to know how much two pieces of bread or pasta or ice cream affected my blood sugar in the three hours I didn’t check it with my glucometer. Even though by the time that three-hour period had passed, my blood sugar returned to a normal state of 80-120, it didn’t mean that in that time, it hadn’t spiked to 300 and come back down. Did I really want to know that? Continue reading →
